We have had success removing white residue. A change of chemical (PCB-Wash or Vigon A200) have a good track record in removing white residue. As Dave stated, we (and others) operate a contract cleaning service. Contact me offline and I�ll provide

Tony, I'm in Ken's corner.....the speeds the manufacturers offer are pretty much meaningless when it comes down to your particular board. Brand X can say they will do 1,000,000 cph but when you put your board on the machine with multiple parts at di

We are using OSP coated boards and no-clean solder paste. In a few instances, we are seeing increased distortion in an audio circuit. Has anybody seen or heard of surface insulation resistance (SIR) decreasing after reflow on OSP boards? Is it possib

IPC [search the fine SMTnet Archives for links] sells 7530 and other documents like it. The frequency that you check your temperature profile depends on: * Confidence that your oven is holding the profile. * Purpose of running the profile, for insta

What is the procedure for insuring that our solder is not contanimated in our wave solder process if we switch between water soluable and no clean solder. We switch between the two types on the same machine during consecutive shifts. Should the entir

I have three Mydata machines and I am very happy with them. The machines are easy to program as well as operate. They are not as fast as some of the other machines but if you change assemblies often you will likely make up some time in setup and cha
