warning - not all stainless steels are non-magnetic! Quite a few alloys are magnetic, some as highly magnetic as ordinary steel. One quick test is to demagnetize the jaws. If you can find one of the old-style Weller soldering guns with the copper

You must try cleaning the heads with a wet head cleaner. Dry tape cleaner just scratches your heads. Demagnetizer is good to use after a good cleaning.

Don't forget the monitor's. There are only two ways to get out of this problem, if the monitor get's magnetizised: 1. Replace the monitor. 2. Turn in the monitor to a Tv-repairman that can do a de-magnetizing of the monitor.

Are the pick up nozzles metal made (ironmagnetic material)? Some time magnetic residual on metal nozzles can generate pbm like that when chips terminations have nickel and when SOt or similar packages have terminal A42 alloy made. Time ago got pbm l

Interesting, thanks for the info. All that I know right now is that running the jaws through an "el-cheapo" demagnetizer was one of the actions taken that resulted in a reduction of missing components. It is possible that this is not a dominant fac

Hi Crishan, sorry, "pbm" is a short way to say problem. In the past ('89), we had same magnetic pbm also with metal nozlles on Dynaper MPS-2500. Some time, we found also chips received from supllier already magnetized. Solution was to put the r

explaining the problem in full each time -> miscommunication/misunderstanding and disagreement). Additionally, I have not, until recently, admitted to tech support that we had modified our centering jaws. I have uncovered evidence that a slight m
