| Hi there Gary, | Your solder ball problem is very similar the problem I experienced, but I was using a water soluble paste at the time. It started by inspectors telling me that they were seeing cold solder on some SIMM's that we had built regularly

Yes, some testing of soldering chip capacitors onto ceramic substrates with high temperature paste proved successful. Die attachment can be achieved using this technology as well. The underfill of the die becomes a critical factor in rework potentia

This is more of a two-dimensional phenomenon than the linear features (wrinkles) that I would associate with disturbed solder. What I should do is contact my own solder supplier on this, I guess, but it hasn't been particularly high on my priority l

Hi Jon, Thanks for that. I seem to be having a problem getting a unit on Trial. I have plenty of access and my main priority is to reduce the amount of dross (or may I say Solder) that we send back as Dross, I am based in Ireland so I have to go t

Hi Mark, I feel like a broken record since I keep replying to this thread. BUT, I remembered a large lytic cap that we had a couple years ago, doing the same thing. The base of the cap would expand in reflow and the bottom would bulge out and only

..and he can put the flux in and keep it a secret too from his customer.. RSS profile on wave?? I never heard of a soak zone for wave preheat...you may be burning off your activator..hence, the beads. For wave preheat, your main goal is to ramp up

Hi All, I was wondering if anyone has experience of printing solder paste on to 2x2" ceramic substrates.. At present we are using a very old de haart printer with a mesh emulsion screen.. I am looking to replace this with a more reliable mo
