Laminator dimmer hack for PCB/stencil toner transfer



The $25 laminator from Harbor Freight works very nicely but at 0.4m/minute it’s too fast for toner transfers. So as suggested by a user on my blog, I wanted to try this mod myself and see how it works, turns out pretty well. My second try gave me a perfect toner transfer on a soda can for making an SMT stencil.

IoT PCB things to consider for Startups

As IoT products are so new, you would assume that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and enduring a lots of technical troubles and delays. That may be not true.
Nevertheless it doesn’t imply IoT startups have a obvious approach to stardom. Facing them is a variety of design and manufacturing considerations that are special to these small products. These things to consider have to be taken into account for the new IoT device to achieve success.

On the plus side, it’s very important for IoT startups to be aware of that the basic foundation for a successful new product exists. This implies experience and knowledge concerning the design, fabrication and assembly of such leading-edge products are obtainable. Additionally, the best advice is for advisable IoT product entrepreneurs and leaders to listen to the recommendation that expert electronics manufacturing services or EMS vendors have to give. These companies together with their engineering team members have practiced the work with revolutionary IoT businesses in Silicon Valley participating in the very first of this coming sector.

The PCB of an IoT unit is a different beast than the traditional one, which is substantially larger and flat. IoT gadgets, on the other hand, consist mainly of either rigid-flex or flex circuit assemblies, which come with their very own sets of design layout, fabrication and assembly things to consider and detailed aspects.

Layout

A top concern is to search for knowledgeable designers who have achieved loads of rigid-flex PCB designs. PCB space for an IoT unit is tight. So you’d like the designer to have direct layout practical knowledge to proficiently design essential parts on that modest area.

Furthermore, nearly all IoT units aren’t fixed; they get considerable movement and folding. Right here, the knowledgeable designer plays a primary role in assessing bend ratios and lifecycle iterations as a serious part of a design. Additional essential design layout things to consider comprise signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are widely used on flex circuits to make sure parts attached to the flex circuit continue being tightly in place to prevent movement.

A new consideration is through-hole part positioning in rigid-flex circuits. How come is that very important? Virtually all of IoT devices are founded on surface mount device placement. Nevertheless , there could be through-hole parts, which are in most cases positioned on either the rigid part or the flex area of the board. Through-hole parts are in most cases useful to communicate input/output or I/O signals to the outside world. Like that, those signals can show up utilizing an LCD or LED monitor. Through-hole part placement is a crucial account in an IoT system for the reason that when used on the flex part of the board, suitable stiffeners need to be designed and implemented for proper assembly.

Eventually in the layout category, the heat that parts bring in is required to be thought of. IoT units are starting to be difficult with rigid-flex and flex circuits featuring up to 12 to 14 layers. Several units are digital. Nevertheless , increasingly analog units are getting used in IoT units. Analog circuitry brings about somewhat more heat than digital ones. This means that heat expansion and also contraction rate ought to be considered. In tech lingo, this is actually often called the Coefficient of Thermal Expansion or CTE and the good handling of it.

Fabrication

Choosing the proper fabricator is essential and is linked to the EMS enterprise you have picked out. The fabricator you want require IoT PCB fabrication practical experience. Amongst essential things to consider here are insuring tough adhesions between layers on both rigid and flex circuit sides, realizing all the crucial calculations and getting a strong knowledge of when current transfers from the rigid side to the flex side.

Such fabricators also need to get an in-depth understanding of incredibly miniature components for example 0201 as well as 00105 device packages, package-on-package, and the utilization of fine-pitch ball-grid array or BGA packaged devices.

Furthermore they should have experience in designing boards with pretty tight tolerances in terms of footprint for those sorts of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They should have laser drills for via drilling with sizes of 5 mils or under because these IoT products could be so tiny that a standard drill size of 5 to 8 mils perhaps may not be sufficient. They may need to go to a 3 mil, meaning you should have an leading-edge laser drilling capability on-site.

In case you’re placing via-in-pad, it’s really a easy way to use the small space that’s available on the rigid-flex board, but it creates difficulties for assembly. If vias aren’t completely planar or flat in shape, it might be challenging all through the assembly of those tiny BGA packaged devices. The reason being that non-planar surfaces can easily threaten the integrity of solder joints.

In some cases via in pads leave bumps in the event that they’re not scoured the correct way after adding the vias and gold finish on the top. In cases where there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices may not be a great joint. It may create sporadic connections, which can be a larger issue to cope with and remedy. It all boils down to which EMS enterprise you’re using because they’re the ones who will discover the fabrication plant to make a triumphant IoT device for you.

PCB Assembly

It’s vital to head over to knowledgeable EMS companies that have correctly assembled IoT and wearable PCBs because they have special tooling and fixtures already available, which are vital for assembly to assure components are placed the proper way, exactly and the printing is accomplished effectively.

Printing could be a headache for IoT units. If it’s a rigid-flex board, then you will find there’s a difference between thicknesses of the rigid and flex circuit portions, signifying a special fixture is required to maintain the complete rigid-flex board planar or completely flat to get effective printing to be realized.

Startups have to be ready to discover the appropriate manufacturing partners and EMS enterprises. This way they can make sure that they have enough experience beforehand to get the multitude of design, fabrication and assembly details correctly performed as they are essential to a profitable and timely IoT product release.

ARM has taken a complete design from concept through to manufacturing a few hundred working units thus far, and learned a huge amount. This may inspire and encourage device makers to advance and innovate faster to make the Smartwatch market a success.

IoT PCB things to consider for Startups

Seeing that IoT appliances are so newer, you would consider that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and undergoing a wide range of technical complications. That is definitely not the case.
Nevertheless it doesn’t signify IoT startups have a very clear approach to fame and fortune. Facing them is many design and manufacturing considerations which are unique to these small products. These things to consider ought to be taken into account for the fresh new IoT product to reach your goals.

On the plus side, it’s a consideration for IoT startups to learn that the foundation for a successful cool product does exist. It implies experience and knowledge involving the design, fabrication and assembly of these kinds of innovative products are accessible. And the most sage advice is for sensible IoT product business owners and creators to take the counsel that encountered electronics manufacturing services or EMS vendors provide. These corporations together with their engineering employees already have undertaken the task with revolutionary IoT corporations in Silicon Valley entering the early stages of this surfacing market.

The PCB of an IoT product is a different beast than the traditional one, which is a great deal larger and flat. IoT products, on the contrary, are made up mainly of either rigid-flex or flex circuit assemblies, which include their own sets of design layout, fabrication and assembly things to consider and technicalities.

A primary consideration is to search out skilled designers who have completed numerous rigid-flex PCB designs. PCB space for an IoT product is scarce. So you want the designer to have directly layout knowledge to successfully design significant elements on that little space.

Moreover, virtually all IoT products are not fixed; they bear significant movement and folding.

Various other significant design layout things to consider contain signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are used on flex circuits to make sure elements installed on the flex circuit remain tightly constantly in place to stay away from movement.

One additional concern is through-hole element placement in rigid-flex circuits. How come is that very important? Virtually all of IoT products are based on surface mount device placement. But there may be through-hole elements, which are often positioned on either the rigid section or the flex portion of the board. Through-hole elements are normally used to connect input/output or I/O signals to the outside world. Like that, those signals can show up utilizing an LCD or LED monitor. Through-hole element placement is a significant concern in an IoT device since when used on the flex part of the board, suitable stiffeners must be designed and employed for proper assembly.

Last but not least in the layout category, the high temperature which elements generate has to be evaluated. IoT products are getting more complicated with rigid-flex and flex circuits featuring approximately 12 – 14 layers. Several products are digital. But ever more analog devices are being used in IoT devices. Analog circuitry delivers way more heat than digital ones.

Startups have to be set to decide on the ideal manufacturing partners and EMS corporations. In this manner they can be certain that they’ve sufficient experience in advance to get the multitude of design, fabrication and assembly details successfully performed since they are key to a lucrative and punctual IoT product roll-out.

#30 Internet of Things with ESP8266 #2: Physically Programming ESP-12



How do you program an ESP-7 or ESP-12 module if it is soldered onto a PCB in your “Thing”? In this video I show my proposal using pogo pins.
I also show how I create the timing to set the ESP8266 automatically into programming mode if the Arduino IDE starts to upload. For this solution, I use an Attiny85.

The code is on github: https://github.com/SensorsIot/Internet-of-Things-with-ESP8266

Internet of Things PCB ways to care for Startups

Because IoT products are so innovative, you would believe that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and suffering from a lots of technical headaches. That is definitely a fallacy.
However it doesn’t imply IoT startups have a obvious approach to fame and fortune. Facing them is a lot of design and manufacturing factors that are special to these small products. These concerns have to be taken into account for the fresh IoT product to reach your goals.

On the plus side, it’s important for IoT startups to recognise that the foundation for a successful cool product exists. This simply means experience and knowledge involving the design, fabrication and assembly of these sophisticated products are existing. Also, the most sage advice is for wise IoT product businessmen and creators to listen to the advice that skilled electronics manufacturing services or EMS companies provide. These corporations in addition to their engineering staffs have previously accomplished the task with groundbreaking IoT companies in Silicon Valley entering the beginning of this growing field.

The PCB of an IoT product is a different beast than the traditional one, which is noticeably larger and flat. IoT units, on the contrary, consist largely of either rigid-flex or flex circuit assemblies, which include their very own sets of design layout, fabrication and assembly concerns and intricacies.

Layout

A primary concern is to seek professional designers who have accomplished a great deal of rigid-flex PCB designs. PCB space for an IoT product is scarce. So you want the designer to have directly layout practical experience to effectively design critical elements on that compact room.

Furthermore, most IoT products are not fixed; they incur substantial movement and twisting. Right here, the professional designer plays a vital role in calculating bend ratios and lifecycle iterations as a significant part of a design. Additional critical design layout concerns encompass signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are widely-used on flex circuits to ensure elements connected to the flex circuit continue being properly in position to protect itself from movement.

An alternative thing to consider is through-hole part placement in rigid-flex circuits. Why is that crucial? Most of IoT appliances are founded upon surface mount device placement. But nevertheless , there can be through-hole elements, which are typically attached to either the rigid part or the flex portion of the board. Through-hole elements are in most cases employed to communicate input/output or I/O signals to the outside world. Like that, those signals can show up employing an LCD or LED monitor. Through-hole part placement is a critical concern in an IoT item since when applied on the flex area of the board, right stiffeners ought to be designed and applied for proper assembly.

And finally in the layout category, the high temperature that elements deliver has to be thought of. IoT products are becoming more challenging with rigid-flex and flex circuits featuring more than 12 to 14 layers. Some products are digital. But nevertheless , progressively analog devices are being used in IoT devices. Analog circuitry cranks out a great deal more heat than digital ones. This implies heat expansion and also contraction rate should be thought about. In tech lingo, that is often called the Coefficient of Thermal Expansion or CTE and the effective therapy for it.

Fabrication

Choosing the proper fabricator is really important and is linked to the EMS partner you’ve selected. The fabricator you expect has to have IoT PCB fabrication experience. Amongst critical concerns here are making sure solid adhesions in between layers on both rigid and flex circuit sides, figuring out all of the significant calculations and getting a solid understanding of when current moves from the rigid side to the flex side.

Such fabricators also needs to get an in-depth expertise in really small-scale components just like 0201 and also 00105 device packages, package-on-package, and the utilization of fine-pitch ball-grid array or BGA packaged devices.

They additionally ought to have experience with designing boards with very tight tolerances in terms of footprint for those sorts of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They should have laser drills for via drilling with sizes of 5 mils or under mainly because these IoT units could be so small that a common drill size of 5 to 8 mils probably won’t be all you need. They may require to go to a 3 mil, which indicates that you need to have an enhanced laser drilling capability in house.

If you are placing via-in-pad, it is a great way to make use of the small space that is available on the rigid-flex board, but it poses trouble for assembly. If vias aren’t completely planar or flat in shape, it becomes hard through the assembly of those tiny BGA packaged devices. The reason being that non-planar surfaces could risk the integrity of solder joints.

In some cases via in pads leave bumps in the event they’re not scoured effectively after positioning the vias and gold finish at the top. In cases where there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices may not be an excellent joint. This could create irregular connections, which can be a larger issue to handle and take care of. It all boils down to which EMS partner you are using because they’re the ones who will select the fabrication house to make a victorious IoT product for you.

PCB Assembly

It’s vital to head over to professional EMS companies that have correctly assembled IoT and wearable PCBs because they have special tooling and fixtures readily out there, which are necessary for assembly to assure components are placed effectively, exactly and the printing is carried out in the right way.

Printing can be a problem for IoT devices. If it’s a rigid-flex board, then you will find a change between thicknesses of the rigid and flex circuit portions, indicating a special fixture is required to maintain the complete rigid-flex board planar or completely flat to make effective printing to be carried out.

Startups should be geared up to decide on the ideal manufacturing partners and EMS firms. This way they can be certain they’ve ample experience before hand to get the multitude of design, fabrication and assembly details successfully performed because they are essential to a lucrative and prompt IoT product launch.

Internet of Things PCB ways to care for Startups

Since IoT appliances are so fresh new, you would think that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and undergoing a lots of technical trouble. That is definitely incorrect.
But it doesn’t imply IoT startups have a certain way to stardom. Facing them is quite a few design and manufacturing concerns that are different to these small products. These concerns need to be thought about for the new IoT device to gain success.

On the plus side, it’s very important for IoT startups to know that the foundation for a successful cool product does exist. This simply means experience and knowledge relating to the design, fabrication and assembly of these types of state-of-the-art products are readily available. Additionally, the most sage advice is for discreet IoT product business men and creators to heed the counsel that expert electronics manufacturing services or EMS companies have to offer. These companies along with their engineering staffs already have practiced the task with groundbreaking IoT companies in Silicon Valley participating in the initial phases of this growing segment.

The PCB of an IoT device is a different beast than the traditional one, which is greatly larger and flat. IoT products, in comparison, are comprised mostly of either rigid-flex or flex circuit assemblies, which come with their own categories of design layout, fabrication and assembly concerns and subtleties.

Layout

A top consideration is to look for knowledgeable designers who’ve completed loads of rigid-flex PCB designs. PCB space for an IoT device is tight. So you’d like the designer to have directly layout practical experience to proficiently design critical elements on that limited room.

Aside from that, most IoT products are not fixed; they have sizeable movement and rotating. Here, the knowledgeable designer plays a key role in determining bend ratios and lifecycle iterations as a significant part of a design. Other critical design layout concerns contain signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are utilized on flex circuits to reassure elements installed on the flex circuit continue to be tightly constantly in place to stop movement.

One additional thing to consider is through-hole element placement in rigid-flex circuits. Why’s that critical? The majority of IoT products are founded upon surface mount device placement. Yet , there could be through-hole elements, which are typically put on either the rigid section or the flex area of the board. Through-hole elements are in general helpful to communicate input/output or I/O signals to the outside world. Doing this, those signals can be exhibited employing an LCD or LED monitor. Through-hole element placement is an essential consideration in an IoT item as when applied to the flex part of the board, appropriate stiffeners have to be designed and applied for effective assembly.

Last of all in the layout category, the high temperature that elements generate must be deemed. IoT products are getting more difficult with rigid-flex and flex circuits featuring as many as 12 – 14 layers. Several products are digital. Yet , more and more analog devices are getting used in IoT devices. Analog circuitry causes a great deal more heat than digital ones. That means heat expansion and also contraction rate should be evaluated. In tech lingo, it is generally known as the Coefficient of Thermal Expansion or CTE and the proper remedy for it.

Fabrication

Finding the right fabricator is critical and is linked to the EMS firm you’ve picked. The fabricator you like should have IoT PCB fabrication practical experience. Among critical concerns here are insuring intense adhesions in between layers on both rigid and flex circuit sides, bearing in mind all the critical calculations and having a strong know-how about when current moves from the rigid side to the flex side.

Such fabricators also have to have an in-depth understanding of incredibly little parts including 0201 as well as 00105 device packages, package-on-package, and the employment of fine-pitch ball-grid array or BGA packaged devices.

Furthermore they must have experience with designing boards with fairly tight tolerances in terms of footprint for those sorts of BGA devices, in terms of up-to-date capabilities like laser direct imaging for putting the solder mask on the board. They ought to have laser drills for via drilling with sizes of 5 mils or under because these IoT products could be so little that a regular drill size of 5 to 8 mils probably won’t be all you need. They could have to go to a 3 mil, meaning that you have to have an state-of-the-art laser drilling capability on-site.

If you are placing via-in-pad, it is a fantastic way to use the small land which is available on the rigid-flex board, yet it presents trouble for assembly. If vias are not fully planar or flat in shape, it becomes tricky during the assembly of those tiny BGA packaged devices. The reason being that non-planar surfaces can easily threaten the integrity of solder joints.

Sometimes via in pads leave bumps in cases where they’re not scrubbed appropriately after adding the vias and gold finish at the top. If there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices wouldn’t be a perfect joint. It might create occasional connections, which can be a bigger issue to treat and repair. It all boils down to which EMS firm you’re working with because they’re the ones who will choose the fabrication factory to make a profitable IoT item for you.

PCB Assembly

It’s crucial to look at knowledgeable EMS companies that have successfully assembled IoT and wearable PCBs since they have special tooling and fixtures already existing, which are necessary for assembly in order to guarantee components are placed appropriately, precisely and the printing is carried out correctly.

Printing can be a problem for IoT devices. If it’s a rigid-flex board, then you will find a change between thicknesses of the rigid and flex circuit portions, which suggests a special fixture is required to keep the complete rigid-flex board planar or completely flat to permit effective printing to be reached.

Startups should really be geared up to decide on the most suitable manufacturing partners and EMS companies. In this manner they can ensure they have ample experience in advance to get the multitude of design, fabrication and assembly details efficiently performed since they are essential to a triumphant and on time IoT product launch.
