Then BeagleCore™ is the perfect solution to turn your idea into professional and mass production ready product – hassle free!
BeagleCore™ can do everything BeagleBone Black does. It’s just smaller and more focussed. You can build your own PCB using BeagleCore™ as a soldering module. Simply develop everything using BeagleBone Black and afterwards realize your product by using BeagleCore™. This makes BeagleCore™ ideal for Internet of Things (IoT) solutions: it’s small, it’s simple, it’s powerful and it follows proven industry standards.
BeagleCore™ is a system on module (SOM) that offers the core features of BeagleBone (processor, memory, IOs) and is made for
inventors, makers and hackers.
We developed BeagleCore™ from scratch. In the beginning it was just an idea. We wanted to create boards for the industry that provide long term availability for the components (7+ years) and at the same time offer support for BeagleBone Capes, programming, etc.
BeagleCore™ is condensed awesome
No more need to implement a BeagleBone Black with all the cables and wires – simply use the ultra-small BeagleCore™ and build your own baseboard around it. You want to use Capes? Fine! Simply add a stacking Header Set to your baseboard along with a BeagleCore™ module
and you can start using BeagleBone Capes just like with a standard BeagleBone Black. Or maybe you want to add custom connectors to directly address your devices without using any Cape. Or remove the HDMI port, add more USB ports or any feature you like. BeagleCore™
unleashes your creativity while remaining compatible with BeagleBone Black at any time. It’s just a condensed version of a standard BeagleBone. See how tiny BeagleCore™ is, compared to other every day things around you:
BeagleCore™ is just a third of the size of a common BeagleBone Black. Still it offers the same functionality for all the core
features. We are using a well selected pin assignment in order to give access to all features of the BeagleBone Black. So if you can
run it on BeagleBone, you can run it on BeagleCore™ as well. Plus you have the advantages of creating your own PCB layout and not only rely on Capes to enhance your baseboard. This extends the possibilities of BeagleBone and almost sets no limit. If you can think it, you can build it.
IoT PCB considerations for Startups
Considering IoT devices are so cutting edge, you would consider that getting an IoT printed circuit board (PCB) project off the ground starts by reinventing the wheel and dealing with a good deal of technical trouble. This is untrue.
Nonetheless it doesn’t indicate that IoT startups have a certain path to fame and fortune. Facing them is a lot of design and manufacturing factors which are unique to these small products. These things to consider have to be taken into consideration for the fresh new IoT device to succeed.
On the plus side, it’s necessary for IoT startups to know that the basic foundation for a successful cool product does exist. This suggests experience and knowledge involving the design, fabrication and assembly of such state-of-the-art products are readily available. And the best advice is for discreet IoT product businessmen and forerunners to listen to the counsel that expert electronics manufacturing services or EMS suppliers provide. These businesses and also their engineering employees have previously accomplished this work with groundbreaking IoT firms in Silicon Valley entering into the early stages of this surfacing field.
The PCB of an IoT product is another beast than the traditional one, which is considerably larger and flat. IoT units, conversely, are comprised largely of either rigid-flex or flex circuit assemblies, which include their very own categories of design layout, fabrication and assembly things to consider and technicalities.
A principal factor is to find expert designers who’ve done numerous rigid-flex PCB designs. PCB space for an IoT product is scarce. So you need the designer to have directly layout practical knowledge to properly design crucial elements on that modest space.
Likewise, virtually all IoT gadgets aren’t fixed; they bear sizeable movement and turning. Right here, the expert designer plays an important role in working out bend ratios and lifecycle iterations as a vital part of a design. Various other crucial design layout things to consider consist of signal trace thickness, number of rigid and flex circuit layers, copper weight and stiffener placement. Stiffeners are employed on flex circuits to make certain that elements mounted on the flex circuit keep on being tightly in place to stay away from movement.
An extra thing to consider is through-hole component placement in rigid-flex circuits. Why is that essential? Many of IoT units are founded on surface mount device(SMD) placement. Nevertheless , there could be through-hole elements, which are typically attached to either the rigid part or the flex part of the board. Through-hole elements are in general helpful to communicate input/output or I/O signals to the exterior world. Doing this, those signals can show up utilizing an LCD or LED monitor. Through-hole component placement is a key consideration in an IoT product given that when applied on the flex part of the board, proper stiffeners ought to be designed and implemented for appropriate assembly.
Lastly in the layout category, the high temperature that elements bring in is required to be factored in. IoT gadgets are more and more complicated with rigid-flex and flex circuits featuring over 12 – 14 layers. Some gadgets are digital. Nevertheless , increasingly analog units are being employed in IoT units. Analog circuitry stimulates considerably more heat than digital ones. Therefore heat expansion and then contraction rate ought to be taken into consideration. In tech lingo, this is actually termed as the Coefficient of Thermal Expansion or CTE and the effective handling of it.
Deciding on the right fabricator is really important and is linked to the EMS enterprise you have picked. The fabricator you want has to have IoT PCB fabrication practical experience. Amongst crucial things to consider here are guaranteeing robust adhesions between layers on both rigid and flex circuit sides, realizing all of the vital calculations and having an excellent knowledge of when current transfers from the rigid side to the flex side.
Such fabricators also have to possess an in-depth knowledge of remarkably small components similar to 0201 as well as 00105 device packages, package-on-package, and the use of fine-pitch ball-grid array or BGA packaged devices.
In addition they must have expertise in designing boards with extremely 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 must have laser drills for via drilling with sizes of 5 mils or under because these IoT units could be so modest that a normal drill size of 5 to 8 mils might not be adequate. They might have to go to a 3 mil, meaning that you have to have an excellent laser drilling capability on-site.
In the event that you are placing via-in-pad, it’s really a easy way to take advantage of the small space that is available on the rigid-flex board, nonetheless , it produces difficulties for assembly. If vias are not entirely planar or flat in shape, it will be a difficulty throughout the assembly of those tiny BGA packaged devices. The reason being that non-planar surfaces might put in danger the integrity of solder joints.
At times via in pads leave bumps if they’re not scrubbed appropriately after positioning the vias and gold finish on the top. In case there are bumps, then the solder joints in the assembly for those tiny BGA balls in those IoT devices might not be an excellent joint. It may create sporadic connections, which can be a larger issue to deal with and improve. It all boils down to which EMS enterprise you’re working with because they’re the ones who will decide on the fabrication house to make a victorious IoT item for you.
It’s very important to pay a visit to expert EMS companies that have efficiently assembled IoT and wearable PCBs because they have specialized tooling and fixtures already available, which are vital for assembly to make sure that components are placed properly, accurately and the printing is conducted in the correct way.
Printing generally is a concern for IoT units. If it’s a rigid-flex board, then you can find a change between thicknesses of the rigid and flex circuit portions, which suggests a special fixture is necessary to retain the complete rigid-flex board planar or 100 % flat to help effective printing to become accomplished.
Startups need to be prepared to pick the proper manufacturing partners and EMS corporations. In this manner they can assure they have got enough experience beforehand to get the multitude of design, fabrication and assembly details effectively performed because they are essential to a thriving and prompt IoT product launch.
