Dear all is there anyone knew about burn-in process and what type of solder must be used for burn-in-board? And, what the maximum temp during burn-in process? Thanks in advance.

PCBA Burn-in / ageing equipment

PCBA Burn-in testing: We need to test some products from -40c - +71c and need some testing equipment for it. We have some burn-in equipments but not at the this temperature range and not at the 7c per minute change rate that is needed. Anyone have so

WS flux vs test socket cleaners? --- Similar BUT Different

Electronics Forum | Mon Mar 16 08:44:42 EDT 2015 | davef

The environment of a burn-in chamber is specific. That environment has a fairly well defined affect on the metal contacts of a burn-in socket. Test socket cleaners are tailored for those specific requirements. Look at the MSDS for the WS flux and th

I have a problem run in Burn-in-Board that the sockets lead are deform and lifted about 6 mil to 10 mil from PCBA. Anybody can inform to me for this problem. Thank you

Stencil Fiducials

The E5s I had just needed the fids to be burned black. Never needed epoxy, although we did have one stencil that we had to touch up with a sharpie now and then because they didn't burn it dark enough (too hot...?).

WSOL and solder pot

Electronics Forum | Fri Mar 14 11:18:29 EDT 2008 | operator

The way it works is the liquid solder immediatley cures (or should I say burns) the WSOL where ever it touches it. This hardens and keeps it in place and protects whatever is under it. Some of the WSOL falls of in the pot. I am suprised that the burn

I am having trouble determining what the IPC classification is for the attachment. Also... if a burn, is it a defect and for what classes? Thanks

Solder splash from component terminal

Electronics Forum | Mon Feb 13 10:41:14 EST 2017 | dyoungquist

Could be that your temperature ramp up rate is too fast. This could cause the flux in the solder paste to burn off too rapidly. When that happens, it can expand as it heats up and burns off, causing the solder to get spread out from the pad.

You are lucky, out of 4 machines we have 2 failed withing first year. One has Panasonic X-axe servo driver burned. The other machine has the ASIC board burned. Nothing that can't be repaired, but still annoying as we had to wait 1 month for replaceme

Thanks Dave F for you 2 cents. You bring up some important points that what one person is doing isn't neccesary right for us. Someone might burn in their boards for 10 hours in temperature but their ramp time is only an hour versus someone else is
