It's never been there and it wasn't supposed to be there, as it is not the original surface. Should I post the last image? :-) Regards, Vlad

Electro-mechanical assembly specification?

Electronics Forum | Tue Aug 26 13:28:50 EDT 2008 | qaman

I am new to the board so be gentle with me. There are standards such as IPC-610 for PCB assembly, IPC-600 for bare boards, etc. Is there a "standard" for electro-mechanical assembly? Is there an IPC standard or any other industry approved standard

Cleaning Wave solder fingers and chain

The chain and fingers for our Wave solder is getting a large amount of residue from the flux (high dissolved solids) we are using. Any recommendations for products that can clean polymerized flux.

We roll ours up, fingers and all, and soak them for about an hour in a solution of water and DOMINATE (heavy duty degreaser) you can order from Grainger. They come out looking brand new every time!

We use a power washer, blow dry, then lightly oil the links with mineral oil. Works great

We use immersion tin boards and ENIG with Sn63Pb37 with no problems. We did have to tweak the profile higher with ImmSn though.
