Problem with solder joints in wave solder

Electronics Forum | Tue Jan 21 13:51:19 EST 2014 | rgduval

Armando, Is the problem in the same spot on the board with every run? If so, there might be something about that particular location that is part of the cause (ie. ground or power plane connection). It sounds like you're seeing blow holes, or insu

Re: Second wave elimination

Hany: In response to your questions: 1- In a double wave solder M/C, is possible to completely eliminate the second wave without affecting the quality of the solder joints? Many w/s machines have a turbulent wave and a smooth wave. The turbule

Solder Paste not dry after Wave

If we understand correctly, your SMT solder connections remelt when passing through the wave solder machine and your QA-people don't like it when that happens. It's nice not to remelt this solder, but as long as the board meets your acceptance stand

Re: Wave Solder Dwell Time

Electronics Forum | Mon Nov 06 21:09:47 EST 2000 | Dave F

That's cool that you used the Archive. Consider running a designed experiment on your board, using your flux and solder, the limits from the Archive, and on your machine to dial in the spread in dwell numbers you see in the SMTnet Archives to your s

Platitudes about soldering are: * People ARE NOT good at soldering. * Machines ARE good at soldering. You can purchase a good used wave soldering machine for $20k. * Training helps people to be better at soldering. * Your solder connections should

Hello. We have a Minipak 300 wave solder machine from Electrovert and are looking in particular for a tachometer that attaches on the finger conveyor motor to measure the speed in pulses. We are also looking for the thermocouple that is used to moni

Dave: I haven't located something to support your contention, yet, and I'm not going to comment on the factors that drive reliability beyond component selection, because I know that you've got some sweaty-palmed sales type wringing his hands waiting

Have you taken a look at our SolderStar range of profilers. We offer 4,6 and 12 channel versions. Our 12 channel system can also be connected to our Wave Shuttle product for wave solder machine analysis. Our datalogger are the smallest reflow profile

Re: Measuring Board Deflection

Electronics Forum | Wed Jul 12 21:32:59 EDT 2000 | Dave F

John: Several thoughts: 1 What on your wave machine are these bowed boards catching on? It has to be something on either wave. Are you getting hung-up on the chimney? That doesn't seem correct!!! 2 Why do you want to measure the defection of y

Wave Soldering with or w/o Nitrogen

Electronics Forum | Tue Mar 12 22:27:50 EST 2002 | davef

I'd speculate that the properties of a well formed solder connection processed in air and N2 are indistinguishable. Then again, the pitch is that N2 gives a wider process window, especially for NC flux-types. In the SMTnet Library look for: �Opti
