Should solder paste be placed back in the refrigirator after use? If so, is there a limit on how many times we may take it out and re-refrigirate it? After receiving solder paste, it is put away in the fridge. Then, removed a few hours before use

Grant, The strength of the joint in a CCGA is the column for one...it's more ductile, made out of 90% Pb, and it's meant to compensate for the massive CTE mismatches between the ceramic and the board (ie the columns flex to relieve stress from the e

In fact, we can solve this problem easily. AOI only check whether the IC is soldered well. But we can ask our technician to make a test first to control the reflowing temperature and time. 1. using tool to test the temperature between the bottom IC

Hi Peter, There is no Silver in it, which even in small quantities (0.3%-4%) improves solderability. I would try and see a demo on a similar machine to yours with a similar product as everyone can get their solder to look great in lab/showroom site
