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?

I would suggest 7mm thick "Durostone" as a carrier material. Cut lip/pocket for PCB so it is 0.05" thinner than thickness of PCB. Allow 0.010" gap on all sides of PCB. Machine lip to width between 0.050" and 0.100" to support under perimeter sides

It was a nice discussion. What I did here was a thermal shock test 1 hour@ +90 deg.c and immediately 1 hour @ -40 deg.c. The second test I did was a high humudity test for a week. After each test, I carried out a peel test with scotch tape. Those bo

Hi everyone, I am starting to use the lead free process and I had a few wetting problems (solder did not reach top side) at the wave soldering process once the pcb had passed our smt line (one heat pass). From what I understand, I have had a problem

We have one panel of 50 small boards that is 0.035" (0.89mm). Other than a dedicated fixture to support it during printing and placement we don't do anything differently. John Thorup

emmanuel, John's right, as long as there is support, nothing changes. Depending on the size of the board fixtures might be a better option over support pins. Unless the pins jump out of the machine and follow it into the reflow oven, You never know!!
