A Little Background

The Innovation Heart of St. Vrain Valley Colleges seeks to transcend the normal classroom and offers experiential alternatives which might be growing right now’s college students into tomorrow’s leaders, innovators, and change-makers. As part of these efforts, the Innovation Heart hosts dozens of “mission groups” throughout a number of focus areas that search to finish actual tasks for actual individuals alongside business companions who present unimaginable mentorship alternatives for college kids.

SparkFun Electronics has been a long-standing companion with The Innovation Heart. Trade specialists from SparkFun have generously offered their time, power, and experience to college students – largely within the type of mentorship. This mentorship has been key in seeing a number of tasks get off the bottom, and the afternoon of Might thirteenth proved to be no exception.

Electrical Engineer, Pete Lewis, has been serving to the Electrical crew from Aquatics Robotics of the Innovation Heart for a bit over 2 years, serving to with the structure of the board in Eagle and the bodily manufacturing of the PCB. When laying out the board in Eagle, Pete defined many necessary steps to designing the board, corresponding to library work, hint placement and strategic half placement.

The Challenge

The Electrical crew was tasked with making a PCB for controlling and distributing energy to 6 motors. This PCB is designed to function on an underwater remotely operated rover, known as Rapids Prototype. The Electrical crew consists of Alex Fong, Ben Howard, Ben Gunn, and Ian Labadie. Alex, and Ian have been the unique designers of the board, with each Ben’s becoming a member of at a later time.

Sparkfun was essential within the completion of the board. As a way to full the board, exterior electrical elements wanted to be soldered onto the board utilizing solder paste. The PCB required a mess of Floor-Mounts which have been positioned on high of the respective pads, By-Holes, which might stick by way of the board and require guide soldering, and Ball-Grid-Array elements, that are extraordinarily small and arduous to put with out the right gear. Sparkfun had an oven completely suited to solder paste. When all of the surface-mounts and Ball-Grid Array elements have been positioned, the oven might warmth and solder each half on directly. As well as, the workers and employees have been very beneficiant with serving to out and the job grew to become a lot simpler.

At Sparkfun, step one to soldering the board was stenciling. With stenciling, there’s a template for the PCB that’s used to put solder paste on the pads. It’s a two-step technique of making use of solder paste and cleansing the surplus solder to be reused. Every member took turns making use of solder and cleansing it off utilizing putty knives. When Ben Howard completed stenciling the board, the crew had roughly 2 hours to put all of the elements on the pads with solder earlier than the paste dried fully. This was a serious problem because the crew had over 400 elements to put over 3 boards. The crew created an meeting line system inserting the identical elements on every board and eliminating elements off the listing on all boards.

It was particularly exhilarating to put the elements within the oven with each half positioned. We needed to be cautious strolling down the steps from the Sparkfun classroom, and cautious strolling to the oven due to the quite a few quantities of elements on every board. Sparkfun’s oven is designed to behave like a conveyor belt that heats up at totally different locations within the belt. That is tuned to completely warmth up solder paste. Whereas it was merely a conveyor belt oven, it was superb to see all 3 of our boards come out soldered with our elements on.

In Conclusion

Total, working with Sparkfun was an incredible expertise, whether or not it was working with Pete Lewis on-line and inserting elements on a board in CAD, or with the ability to work in-person to complete a board. The Electrical crew wouldn’t have gotten so far as it has with out SparkFun’s gear and superb engineers. There have been so many enjoyable and distinctive points of interest that added onto the expertise at Sparkfun Electronics and it was superb to undergo the method of stenciling, bodily inserting, and cooking printed circuit boards that have been in improvement since quarantine.
