Board Assembly News!

Happy New Years

I hope you all have had a good year and have many things to look forward to in 2023! Thank you for helping Bee Motion S3 reach its funding goal! We will continue to take orders as we prepare to assemble your Bee Motion S3s. This update talks about how these boards are being assembled.

Picking and placing all the parts!

When it comes to assembling circuit boards it can be a fun experience hand placing all the components in small batches, but when you need to build a lot of boards, hand assembly can be very time consuming and prone to mistakes. That’s where a pick and place machine comes in very handy.

If you’re unfamiliar with pick and place machines, they do pretty much what the name describes. They will pick all the components and place them on a PCB to assemble and solder the components to the board, and they do this a lot faster than a human can do when placing the components by hand.

How much faster is a PnP? They vary in speed and functionality, and my PnP is much faster than hand-assembling Bee Motion S3s. There are 43 components that are needed to populate a Bee Motion S3. If i’m hand assembling them, I can make about 5 to 6 boards in an hour if thats all I’m doing with no distractions. With my pick and place, I can build about 30 in an hour, which is a substantial difference in speed and efficiency!

The faster I can assemble and test them, the faster I can get them shipped to Crowd Supply to be distributed to you!

Stay tuned for future updates, where I’ll outline how I plan to fully test every Bee Motion S3 that ships.

As always, I really appreciate all the support and I look forward to getting these into backers hands as fast as possible.
