Another equipment manufacturer is Smart Sonic. Most equipment manufacturers have their own chemistries, but they are also willing to use other cleaners. What we have done is to send boards that need to be cleaned to the equipment manufacturer. W

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

We are preparing a batch of samples for test. several IC which packaged by BGA/CSP was removed from PCB by reworkstation. However, I need to re-use this IC. I want to know whether there is a way to remove the solder balls from these IC devices and ca

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

Steve, Moisture sensitivity needs to be taken seriously. Being in the commercial end of electronics now, I am using many plastic packages. Unfortunately, moisture sensitivity processing is not black and white and it does require procedures and dis

Our company laser re-ball's BGA down to 100 microns ball size. One of our OEM customers have asked us to function test there BGA on Mobile phone PCB's. Origionally we thought of a test sockets however the sockets interfere with other devices on the P

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
