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

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

DC powered Power-up and ageing burn-in equipment, preferably non-product specific, starting from room temperature down to -41 degrees celcius and up to +71 celcius at a rate of 7 celcius per minute. But anyone who could suggest a manufacturer would b

This happens to be after the water wash process. These are Burn-In boards so an SMT epoxy is used prior to wave. The flux used is Kester 2331ZX. Would using a thinner cause this to occur? The residue is all over the board. Thanks.

Hi dave, Thanks for the comment. I have another issue. The board already pass Test and Burn-In processes, but after 2 months the BGA contact is found open (no contact on certain balls). How can that happen? Is it during build, the solder ball alrea

Ooops sorry! Has anyone ever had a problem with using FR4 for a burn-in board? We suggested using Nelco or getek, but will FR4 have any problems in the assembly area through the solder wave?

Try looking at Chart Industries. They offer HASS/HALT chambers that are capable of reaching the paramaters that you are looking for. Will require a nitrogen supply for the cooling end.We had a 3000gal tank of liquid nitrogen to feed two chambers.

We use Sharetree equipment for this task. Good for up to around 30 deg. c per minute ramps if required with liquid Nitrogen cooling.
