Hi Graham, I've worked in the industry selling EnSolv, Lenium, and now ENTRON solvents, which are all based on stabilized NPB. These solvents do not always clean the no lead pastes. The problem is that the pastes are becoming more like adhesives,

I'm looking for the dielectric values of materials for flex, rigid and flex/rigid pcb construction. Has anyone put together tables for this information? Where can I find the information to figure out what dielectric resistances I need based on altitu

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

I agree with dry wiping. We have 4 SPM's and 2 AP25's, we have never had a need for solvent. I would be cautious using alcohol/ or alcohol based solvents.

MLCC crack detection

Thx for the replies. Acutally I am doing a process related study to see whether the process (pcb depanelling)can induce crack to an MLCC. After depanelling, I will do a thermal shock on the MLCC based on IEC 384-1, that is, five cycles of 30min at hi

You'd more than likely have repairability issues with the Acrylic based one. The acrylic-based finish is alot harder and more brittle versus the silicone. Some of the new silicones, you can just "peel" with your fingernail, while still getting reli
