Dave is there an easy way to calculate liquidous temp? or just a ball park for Hasl boards / BGA's. I placed a thermal couple with kapton tape over a BGA to get the approx profile. Thanks, Kevin

Don't worry Kevin, the boards will be in space, so about as far from you house as possible! The process is mapped out and proved, and was recorded as a six sigmas process. The operator of the process, on the otherhand, wasn't. Chrissie

Kevin, Agree with John's thoughts on profiling and the max temp of 240 degrees in particular. To add to it a bit we have seen the following parameters put in place at many assembly houses to protect against overcooking the components: --Time above

This is the book that Kevin wants to sell: http://www.elchempub.com/epfiles/ep29.htm It is a very good book and covers topics, like pad design for wave soldering SMT devices, that no other authors touch upon.

We had the same issue. Switch to the 440-R and remove your heat. Your wash cycle can be changed down to 2 minutes. Make sure to mix the correct amount, and you want have anymore delam's. Kevin S
