Running a soldered BGA through a wave solder pot is very risky: * 230-240*C temperature of the pot could damage the device. * Solder in the pot will certainly cause bridging between BGA solder balls. * Solder in the pot could melt BGA solder balls.

I'm looking for information on "volcano" soldering or mini-wave soldering. I need to solder a leaded device, thru-hole, on a already populated smt PCB. I want to do localized soldering on the pins of the device. Any help would be greatly appreciated

In the IPC-A-610E standard QFNs are classified as BTC (bottom termination components). Most QFNs do not have a solder-able surface on the outside of the part. Usually the lead that you can see on the outside is copper and classified is not solder-a

What selective soldering products should I use for a low production rate, high-mix product line? I am looking to get rid of some hand soldering. I have seen exselect (selective soldering pot method), pillarhouse (small flow solder nozzle with robot),

Hello Mark, I'll assume that you are currently wave soldering and would like to eliminate that operation by using pre-forms or press-fit connectors. Solder preforms or solder flux bearing connector leads usually do not require any hole size changes,

After following the suggestions above, and where it would not be possible to mask BGA by soldering fixture, a Kapton tape (pre-punched) can be placed under BGA ( wave solder source side ) it can help to keep temperature low enough avoiding "seconda

we are manufacturer of molded type transformer and we soldered are units using wave soldering machine and then we washed the units to remove flux residue. what materials or any process for us to eliminate the process of washing after wave soldering.

Looking for the best choice in books on soldering processes, primarily reflow but wave is going to be with us for a while so..... If you had to buy one today, which would you start with? Here's the list I gleened from the archives: Coombs, CF, "Pr
