PWB Bake out or other elevated temperture processes can cause issues with oxidation of that Nickel layer. The gold porosity can vary from batch to batch, but also process changes can contribute. Are you baking the boards or have previous reflow pro

| | |Hi all | | This Debate on lead free soldering is really hotting up here in Europe. From 2004 the use of lead in components and assemblies will be banned here. Also flame retardent halogens will be banned(FR4 etc). While we all agree that we hav

We all seem to have forgotten about cover tape peel force testers. GPD makes them as do others I suppose. I would ask the tape and reel house if they have a tester. If they don't I would consider using someone else. Otherwise as another poster s

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

It seems like we had a similar issue once on a CP643. If I remember right it ended up being either pre or post theta. The amplifier for the sensor quit working and it was trying to zero the theta motors before doing the cam. The LED indicator on t

Hi Chuck, let�s say it the other way round. We use noclean since I can�t even remember without nitrogen and all of our subcons do with no known problems. The processes are adapted to it and no complaints are heard up to now. That is related to our pr

I take it you are talking about the older style IP feeders. If so, here is what you need to do..... Get yourself some mineral spirits,a tub you can submerse the parts in, and a couple nice paint brushes. 1.Dismantle the feeder and wash all of the

We have a name brand aqueous batch cleaner that uses a chemical and DI water to clean ROL0 flux from our PCBs. It does ok most of the time for SMT boards and we want to include through hole assemblies as well which should be a better cleaning process

I agree. Trim the leads before insertion, then raise the pot height. With the information given, this is most likely your solution. Our machine has a dam wall on the rear of the solder pot that raises the height on the solder pool. I would make sure
