Hi, As I have seen in the data sheets from solder paste suppliers they always recommend to keep the solder paste until it reaches the ambient temperature after taking out from normal storage temperature. Mostly the storage temperature is 5 - 10 Cels

All solder pastes are worth consideration depending on your needs. What do you need to do? When you know this, run the experiment and determing what best works. I never have found a situation when/where Indium or Kester has failed to perform. This,

Any decent 7-zone reflow oven rated at 300 degrees C will handle lead free. Prices for used ovens in this range begin around $15K. For waves, the prices are all over the map. Send me a private e-mail and I'll introduce you to a friend of mine who sel

We are trying to apply solder to boards with 80 microinches of electro plated hard gold. No components involved, just print 63/37 paste and reflow. The results are very poor on some boards, not so bad on others? Pictures at http://www.sipad.net/thick

Identify the machine/program variables that can change the results on a standard sample, DOE to identify the range of each variable within which you still net the correct result, then verify before startup that each variable is within the allowable r
