Could be not enough peak temp. Do you have a profiler? I'd measure at the BGA joints- drill under board to get access to BGA solder joints and embed a couple of thermocouples with hi-temp solder, then run your profile to see max. temps. and that prof

A customer of mine has a Quad 4C that will not home in the X. It used to have the problem in the Y then they changed the cards and now that machine will not home in the X when powered up. Anybody have any ideas. I think I know what the problem is, bu

I by all means, am not an expert on Wave processes. But, our second bottom side zone for our wave is down. My boss said "well the flux looks okay, just run it" and won't give me the machine to properly fix. How many people have a problem with thi

Hi Ed, It all depends on more info needed. How many preheaers do you have in your wave? One, two, three? Are you talking bottom side preheat? What size boards do you run and what type of parts are on it. Typically, preheat does several things; w

Sorry it has taken me so long to respond. I got pulled off onto other projects and was not able to work on the solution to the problen until recently. The solution we have come up with is to change from no-clean flux based solder paste to water sol

I am seeing poor quality solder joints, mostly on 0402 components. The problem is that while the pad on the pcb is getting fully wetted, the solder is not flowing up the sides of the 0402 component, i.e. the 0402 lead is somewhat de-wetting. The re

Check specific gravity: According to a quick web search, the specific gravity should be 0.813 ± 0.003. If you have records of the specific gravity, compare current reading to past readings. Check pressure near stone: if you have records, compare

Make sure that your fiducials are selected to be used for global correction. I've had this problem with our machine running OS2, and in the UI for that, you have to select the fiducials in the fid screen, and then there's a menu option to select the
