When I said partial build I should have clarified that all the boards we build are double sided so the plan is to build the bottom side then build the top side as they are ordered. The bottom will be standard and the top will have the options. I di

We handle this issue by adding a .1, .2 etc after the existing rev. Ex. Rev is A - we do an internal Rev changing an item and it goes to Rev A.1 - Basically you are building a Rev A with that ECO applied to it. It works well but you need to pay atte

To be precise, the component is a Xilinx Virtex platform FPGA with 1152 balls. We also assemble some DSPs up to 1000 balls with metal cover. At best, we can remove the components but it is almost impossible to find a working solder profile using IR.

We have a 1.6 mm thick automotive PCB board of size 35x70mm. One of our vendor has given us a batch with lesser soldermask thickness 5~8 microns. Will this affect the circuit board on a long term. What should be standard for the soldermask thickness?

Please help, we have by mistake repaired some boards using the wrong flux (water soluble on a no clean board). Unfortunatly we found out later on while we are testing the boards. The lab anyalysis clearly showed that the flux has eaten through the

Guys When stripping conformal coating from an entire assembly, how do I know the stripping solution won't damage anything on the PCB ? stuff like electronic sensitive devices, wiring, labelling and plastic hinges. And secondly when conformally coati
