Has anyone any experience of using completely dry under stencil cleaning. I have recently been sent some information regarding Micro�Wipe� FP cleaning rolls. The claims about their performance are pretty good, but then what are they like in reality?

Hi, It depends on the stencil thickness, aperture size and the component footprint. For exampl if you have a PCB with QFP,CSP,QFN & BGA parts then this underwiper is not useable because you will still find solder cream deposits in the apertures aft

Hi Manuel, most passives are chip components. These tend to self-center/align during the reflow process. However, you need to ensure that there is a uniform balanced solder paste deposit. I had tried few such ovals in earlier stencil designs and resu

I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

Philip, Pl note that there is one more fabricator from Malasia, whom we found to be up to the mark with Wave Soldering Pallets constructed with Durastone/CDM Durastone. They also offer ESD Protected to match ESD guidelines of Assembly & Photo Sensi

So there is no "DI Water" standard, but what is max conductivity I should have coming from my water before I let it touch the boards? We just installed a DI system in our plant down in Mexico and our water analysis shows we now have HIGHER conductivi

Conductivity is the recprical of resistivity. So, ... * 10 uS = 100k ohm * 5 uS = 200k ohm * 2 uS = 500k ohm We're unsure of the units of your conductivity of "1,566 uS/cm". Also, is that one thousand, five hundred, sixty six?
