Internet of Things PCB considerations for Startups

Seeing that IoT devices are so newer, you would think that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and suffering a good deal of technical difficulties. That is definitely untrue.
Nonetheless it doesn’t indicate that IoT startups have a evident route to fame and fortune. Facing them is quite a lot of design and manufacturing points which are special to these small products. These considerations should be considered for the fresh IoT product to reach your goals.

On the plus side, it’s necessary for IoT startups to find out that the foundation for a successful new product exists. This means that experience and knowhow regarding the design, fabrication and assembly of such leading-edge products are out there. Also, the best advice is for discreet IoT product business men and innovators to become aware of the recommendations that qualified electronics manufacturing services or EMS providers are offering. These corporations together with their engineering staffs have already performed the work with groundbreaking IoT firms in Silicon Valley stepping into the beginning of this surfacing segment.

The PCB of an IoT product is a special beast than the traditional one, which is notably larger and flat. IoT gadgets, conversely, are made up largely of either rigid-flex or flex circuit assemblies, which include their own sets of design layout, fabrication and assembly considerations and detailed aspects.

Layout

A primary factor is to try to find encountered designers who’ve undertaken quite a lot of rigid-flex PCB designs. PCB space for an IoT product is at a premium. So you want the designer to have firsthand layout knowledge to correctly design significant parts on that little room.

Moreover, virtually all IoT gadgets are not stationary; they get substantial movement and turning. Right here, the encountered designer plays a key role in calculating bend ratios and lifecycle iterations as a significant part of a design. Various other significant design layout considerations contain signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are utilized on flex circuits to make certain parts attached to the flex circuit keep on being firmly in place to prevent itself from movement.

A new aspect to consider is through-hole element positioning in rigid-flex circuits. Why is that important? Most of the IoT units are founded on surface mount device placement. But nevertheless , there may be through-hole parts, which are often affixed to either the rigid part or the flex part of the board. Through-hole parts are in most cases helpful to connect input/output or I/O signals to the exterior world. Doing this, those signals can be shown having an LCD or LED monitor. Through-hole element placement is a significant concern in an IoT item given that when utilized on the flex section of the board, suitable stiffeners need to be designed and employed for ideal assembly.

Finally in the layout category, the high temperature which parts generate is required to be considered. IoT gadgets are starting to be more elaborate with rigid-flex and flex circuits featuring as many as 12 – 14 layers. Some gadgets are digital. But nevertheless , more and more analog systems are being used in IoT systems. Analog circuitry creates far more heat than digital ones. That means heat expansion plus contraction rate must be taken into account. In tech lingo, this is actually called the Coefficient of Thermal Expansion or CTE and the proper management of it.

Manufacturing

Deciding on the right fabricator is crucial and is linked to the EMS corporation you’ve decided on. The fabricator you’d like must have IoT PCB fabrication practical experience. Among significant considerations here are insuring good adhesions in between layers on both rigid and flex circuit sides, figuring out all of the important calculations and having a robust knowledge of when current transfers from the rigid side to the flex side.

These fabricators must also get an in-depth comprehension of exceptionally compact parts including 0201 and also 00105 device packages, package-on-package, and the utilization of fine-pitch ball-grid array or BGA packaged devices.

Additionally, they need to have knowledge of designing boards with fairly tight tolerances in terms of footprint for those kinds 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 mainly because these IoT devices could be so little that a standard drill size of 5 to 8 mils would possibly not be all you need. They may have to go to a 3 mil, which indicates that you will need to have an advanced laser drilling capability indoors.

In the event you are placing via-in-pad, it is a good way to make use of the small real estate that’s available on the rigid-flex board, nonetheless , it produces problems for assembly. If vias are not fully planar or flat in shape, it may be an obstacle through the assembly of those tiny BGA packaged devices. That’s because non-planar surfaces could endanger the integrity of solder joints.

Sometimes via in pads leave bumps in cases where they’re not scoured appropriately after putting the vias and gold finish on top. In case there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices wouldn’t be an ideal joint. This might create sporadic connections, which might be a bigger issue to address and remedy. It all boils down to which EMS corporation you are using because they’re the ones who will select the fabrication facility to make a triumphant IoT item for you.

PCB Assembly

It’s crucial to take a look at encountered EMS companies that have successfully assembled IoT and wearable PCBs because they have specialized tooling and fixtures readily existing, which are vital for assembly to assure components are placed properly, accurately and the printing is accomplished correctly.

Printing is usually a difficult task for IoT systems. If it’s a rigid-flex board, then there will be a difference between thicknesses of the rigid and flex circuit portions, indicating a special fixture is required to maintain the complete rigid-flex board planar or absolutely flat to permit effective printing to be achieved.

Startups must be well prepared to discover the most suitable manufacturing partners and EMS enterprises. Doing this they can make sure that they have enough experience beforehand to get the multitude of design, fabrication and assembly details effectively performed since they are crucial to a prosperous and prompt IoT product launch.

A primary thing to consider is to try to find expert designers who’ve completed lots of rigid-flex PCB designs. PCB space for an IoT device is tight. So you want the designer to have direct layout experience to efficiently design significant elements on that little room.

Likewise, almost all IoT products are not stationary; they get extensive movement and twisting. Right here, the expert designer plays a key role in determining bend ratios and lifecycle iterations as a important part of a design. Other significant design layout considerations involve signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are widely used on flex circuits to make certain that elements connected to the flex circuit stay firmly constantly in place to stay away from movement.

One other concern is through-hole element positioning in rigid-flex circuits. How come is that important? Most IoT appliances are founded on surface mount device placement. But nonetheless , there could be through-hole elements, which are generally attached to either the rigid part or the flex area of the board. Through-hole elements are often helpful to connect input/output or I/O signals to the exterior world. That way, those signals can be exhibited using an LCD or LED monitor. Through-hole element placement is a vital factor in an IoT device since when utilized on the flex part of the board, suitable stiffeners should be designed and implemented for good assembly.

And lastly in the layout category, the high temperature which elements deliver must be deemed. IoT products are progressively more complex with rigid-flex and flex circuits featuring upwards of 12 – 14 layers. Some products are digital. But nonetheless , gradually more analog devices are being utilized in IoT devices. Analog circuitry creates far more heat than digital ones. Therefore , heat expansion plus contraction rate should be evaluated. In tech lingo, this is actually referred to as the Coefficient of Thermal Expansion or CTE and the correct therapy for it.

Fabrication

Selecting the best fabricator is critical and is linked to the EMS partner you have chosen. The fabricator you’re looking for has to have IoT PCB fabrication experience. Among significant considerations here are making sure sturdy adhesions in between layers on both rigid and flex circuit sides, knowing all of the essential calculations and having a great expertise in when current transfers from the rigid side to the flex side.

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

They even should have experience with designing boards with highly tight tolerances in terms of footprint for those kinds 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 as these IoT units could be so modest that a common drill size of 5 to 8 mils would possibly not be adequate. They may need to go to a 3 mil, which means that you will need to have an state-of-the-art laser drilling capability in house.

In case you are placing via-in-pad, it’s a good way to utilize the small real estate that is available on the rigid-flex board, nevertheless , it produces trouble for assembly. If vias aren’t 100 % planar or flat in shape, it becomes tricky during the assembly of those tiny BGA packaged devices. That’s because non-planar surfaces may put in danger the integrity of solder joints.

Sometimes via in pads leave bumps in the event that they’re not scoured thoroughly after installing the vias and gold finish on top. In the event there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices might not be an ideal joint. It may create occasional connections, which can be a greater issue to address and fix. It all boils down to which EMS partner you’re using because they’re the ones who will decide on the fabrication facility to make a thriving IoT product for you.

PCB Assembly

It’s crucial to head off to expert EMS companies that have efficiently assembled IoT and wearable PCBs as they have unique tooling and fixtures already out there, which are necessary for assembly to assure components are placed correctly, exactly and the printing is finished effectively.

Printing might be a issue for IoT devices. If it’s a rigid-flex board, then you will find a difference between thicknesses of the rigid and flex circuit portions, which suggests a special fixture is needed to retain the complete rigid-flex board planar or totally flat to enable effective printing to become actually done.

Startups should really be prepared to decide on the correct manufacturing partners and EMS firms. In this manner they can be certain they have got enough experience in advance to get the multitude of design, fabrication and assembly details effectively performed because they are key to a thriving and timely IoT product roll-out.

PCB solder pad repair & corrosion clean up – The epoxy method



This is a demonstration of a PCB repair which involves repairing damaged surface mount solder pads as well as cleaning up corrosion from a leaking electrolytic capacitor. The pads had been damaged by the owner of the motherboard as a result of him trying to repair the board on his own.

I hope that this video will give you some ideas on how to perform a proper pad repair using the epoxy method.
During this repair, I used an epoxy that is heat resistant up to 315°C for 60 seconds.
If you ever find any kind of epoxy on the market that is specified to be heat resistant up to more than 315°C, then I would be happy if you could let us know about it in the comment section as it does appear that high temperature epoxies are quite difficult to find.

The following products was used in this video:
CircuitWorks CW2500 – Two component epoxy overcoat
CircuitWorks CW3300 – Overcoat Pen

I have made several videos before where I have had to fix up other people’s mistakes that they have made during their repair attempts, and this repair only adds on to the list.
If you are not a repair technician and your motherboard has stopped working, it would be in the best of your own interest not to attempt a repair that you really cannot handle. Because there is a huge risk that you will actually end up doing more harm than good. We are of course mostly talking about board damage in the case of motherboards, but it gets considerably worse when dealing with things like power supplies, which can easily become a great shock hazard to inexperienced technicians and even result in electrocution.

As always, comments and questions regarding this repair are always welcome.
