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

I could not see pictures of your board - please attach one or two. So to answer your questions: 1. wave should not overflow over your board - mostly we use pallets as carriers to protect the assembly. 2. Solder dross is caused because your wave is no

I've seen this problem on more than one wave,What i've done is to run the conveyor a little faster,use a solder temp of 505 degrees F,and most important is to make sure that the solder is flowing over the back. this will keep the thin buildup of dros

Higher temperatures are the primary reason that there are more solder balls with selective soldering than in wave soldering. Possible causes are: * Solder mask type is the most important factor ... Solder resists becomes stickier at higher temperatur

I'm currently working in a SMT factory in China. I'd like to know what preparation that I would need to change from leaded to lead free soldering. 1.Starting with the PCB production, things that I need to concern about are solder mask, Cu protection

Sure. Treat it like wave solder. Top side wetting is generaly harder to achieve than wave so don't over look it. On most selective solder machine, the delta-T is also something to look out for. Most move from preheat to pot. And snce the pot por

Hi Allan, I can�t help with literature on that topic but we have great success with solder thiefs to prevent bridging with 2mm pitch THT-connector. We added just blind pads of the same size at the end of each row similar to what you can do with SMD

Good ol' Yankee engineering always says "More is better" You have got to be careful that with more epoxy volume you run the risk of the epoxy merging with solder paste if you are using a glue and paste process. In addition, if the epoxy can spread o
