Hi Rick, Cleaning No Cleans is becoming more of a norm. It is true that changing to a OA flux/paste would be a easier process to control from a cleaning standpoint. A water soluble process will cost a great deal less as well. However, if your pro

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani

AOI vs. electrical test

Electronics Forum | Wed Jan 04 12:48:34 EST 2006 | pjc

In-Circuit Test is the best method for ensuring solder joint connections. It is a much more reliable than AOI. An ICT machine can ensure solder connections are made for array package devices such as BGA, PGA, etc... AOI is best for component I.D.- is
