Soldering Bath - When we need to tin high-power contacts or a lot of wires, for example, in making harnesses, a regular soldering iron is either impossible to use due to the high thermal capacitance requirement, or takes way too long to perform the t

Quick Question! We have an assembly that we're building for a customer that will have to be soldered via a Lead-Free Wave Solder. We do not currently have a Lead-Free Wave Solder in house. Does anyone know of a company that may be able to provide thi

We are currently applying solder bumps to hundreds of BCC's for rework. It is impossible to print to the PWB. It is recommended to apply solder bumps to the BCC's with 63/37 alloy making the rework faster and easier. Applying the solder bump on the

Consider using a roll solder with a flux that well matches the residues you can accept to be remaining on the board when you get finished processing. Many people use a no-clean flux cored roll solder for such operations, because they don't want to c

I have a tendency to agree with CK Experience and accomplishments in wave soldering are more valuable then the degree. Remember wave soldering is not taught in school although it is a vital process in the electronics assembly. The quality and relia

Vlad, Reduce your aperture opening in the stencil, this will give the stencil a good seal around the specific area of concern. In a wave solder environment, solder balling top or bottom surfaces in a wave pallet is caused by excessive flux burning o

What are the industry standards for eutectic solder-paste in conjunction with the life span of solder-paste. What is the recommended duration of solder-paste on a printed circuit board. Example: You print a board, how long can it sit before runnin

You could pay the extra to have the microvias plated shut and planarized. If your voids are larger than 25% of the BGA joint area then I would suspect a solderability problem. Either the board plating or a solder paste problem. If they're less tha
