Your fab has supplied you with unsolderable boards. They are dewetted, due to some process problem. That they are dewetted on the annular ring of the via indicates that the problem is with the board and not with your paste. [We assume you do not p

I can't help you with your soldering problem, but I wonder if a pressfit connector is an option for you. If this connector is available as pressfit, you can avoid the solder wave proces and associated problems. Write me if you are interested in more

This may sound like advertasing, but I ran a DOE with five solder paste/flux manufacturers and somehow, the voids went away with the AIM solder.

There are no industry standards for eutectic solder-paste in conjunction with the life span of solder-paste. Whatever that is. Speaking of that ['whatever that is.'], what do you mean by �life span of solder-paste�? Is that: * Shelf life? * Workin

We are looking for a good solder/desolder machine for state-of-the-art pcb rework. A step up from the Pace/OK Industries is the level I am researching. The application is a nice R&D Lab on state-of-the art PCBs. Anybody who has suggestions or recomme

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

At a previous job we had a kit to splice the belts. It was a clamping and squeeze device and a soldering iron with a flat blade. You would cut the ends for a suare edge, put the belt in the clamp unit with a small gap. Use the iron to melt both en
