Or get the chip to tristate the flash pins, contact them with something else and directly write the flash.
Or program the flash chip before soldering it in place.
Next time around have a connector, edge fingers, or pads for a pogo-pin spring contact jig.
#After Sales #PCB Assembly
How does a conventional board house deal with the issue of reflow during PCB component assembly with BGA’s on both sides of the board?
Are two different solders used (like regular lead free SAC305 and a low temp?)
I want to implement a control system I designed for a light electric motorbike. I would like to mount it as professionally as possible on the chassis. It consists of a power system pcb and a SAMC21 development board which I’ll merge later once this all works properly. I have tried screwing it directly on the aluminium chassis but have found that shocks and vibrations from the horn disturbed the system or even destroyed it upon large shocks. Is there a specific way car and motorcycle manufacturers mount their electronics to make their system as robust as possible?
Our team are developing a portable medical device with a small size, so we need a small PCB. How do I determine the traces width when designing a PCB? Actually we want it as narrow as possible to fit the device, is it OK?
