I have a supplier that want to upgrade all nails on a huge amount of ICT fixture due to test RoHS compliant PCBAs. My thought is that even if there are a very small fraction of residues left on the pins it will never go over the 1000PPM level. In fu

I know this may be a long-shot, but I can really use the reach this forum has. I am looking for an injection molding material called Noryl. The specific compound is SE1X-71944. If you have any of this available, or know someone that does, please repl

This may not be a solution to your problem, but something from my tuner car days jumped into my head. If you are running at 100% and not getting the height you need, change out one (or both) of your pulleys. A bigger pulley at the motor side, or a sm

SuMoTe, that is a fair suggestion, but I believe will be a non-starter. The solder pump motors are actually 40V motors being run from a PWM 24V supply. I did one time try hooking up to a separate power supply up to 40V but all this seemed to do was m

Thanks for the suggestions. 1. By this are you referring to the flux specifications or the actual profile of the machine? 2. Yes, the entire machine, the solder pot and the wave nozzles have all been levelled. The better joints on one side are perp

No matter what machine that you decide to buy some of the things you want to know especially concerning used machines are how readily available are spare parts for the machine. How hard is it to program the machine and are there programs available to

In an excellent previous thread davef mentions brass should be plated prior to soldering to prevent zinc leaching from the brass. It is reported once the zinc leaches, the joint is weak. He recommends copper or nickel plating. Would silver plating w

davef, thanks for feedback. I talked with a plater who said they put copper before silver when plating brass. Would a complete stack of: Brass part, then 0.0001-0.0002" of copper, then 0.0005" of silver, then Tarniban anti oxidation. Sound reasonabl

Claire, my suggestion is different from BentePCB & Pavel Murtishev. Although 500pcs cannot be considered as a mass production order, it's too larger to be placed as a prototype order. And I think the PCB quality & performance is very important, you c
