Who Cares... Mix Away! Although you should not mix different Solder Pastes' together in a container or on a stencil (Mostly due to the flux, although solder sphere size and shape could cause an issue), mixing solder brands or chemistries on a board

Good Morning, I had looked into this several years ago. The Swiffer dust mops use static to capture and contain dust particles. That would make this a huge ESD concern. Electrical SMT equipment is grounded so any charge potential generated would be

Solderability could be an issue. We usually buy the IC and stock it for up to 9 month. This time the ICs was from a broker and the datecode was not the latest. This said, we use already a solder paste that contains watersoluble flux, which is suppos

Hopefully the coating does contain a UV tracer. We used a silicone years ago that did not, but UV did make it fluoresce to a degree, you just couldn't ensure 100% coverage. One time we did have a problem with the coating getting on connector pins,

Yes it is used for PCB, I have used it in the Automotive Service Industry for many uses. Most popular as a Brake assembly cleaning agent. It is popular today due to its low FLASH POINT, unlike other solvents that contain Heptane, Xylene etc thease ha

a long time ago in a galaxy far far away. we had a requirement for a specific part. We stored it in a room in a plastic container on a wooden shelf and had to rent a Gauss meter and walk around and take measurements to prove that it was anti magnetic

Solder paste flux formulation can make a difference when soldering to nickel silver...due to the alloy containing metals that oxidise easily like zinc and nickel then the flux has to be able to cope with the surface oxidation when the parts are in th

Hi, We are having a problem with the interpretation of the surface evaluation criteria of J-STD-003 section 4.2.2.4.2. "A minimum of 95% of each of the surfaces (i.e. each pad) being tested shall exhibit good wetting. The balance of the surface may

I believe that Rain-X contains silicone and Nano-ProTek solution does not. I did speak with a field service guy for Nano-Protek and he told me the special coating test pen that they offer is just a sharpie with their logo on it. Thats how I test to
