Here's a new ban proposal by the EU on the flame retardant deca-BDE. A product that has kept our electronics safe for over decades. The good part is that the scientific community in the EU looks like to put up a bigger resistance as was the case wit

NEW ban proposal? It was exempted from ROHS and that exemption was lifted during the summer. I made a post about it no longer being allowed back in July. Here's a link I posted. http://www.rsjtechnical.com/NewsDecaBDE.htm

Stephen, You're absolutely correct I totally miswrote the post. What I wanted to highlight is the efforts from the reachforlife organization. Decision making should be based on scientific evidence. http://www.reachforlife.eu/home.php?lg=UK

Flame retardant epoxy-glass circuit boards are made using brominated epoxies,with the bromine atoms providing the flame retardancy.In a fire,these boards can give off toxic gases.Bromine free epoxies can be used,with other additives being used to pro

We use (and have for some time) used No-clean on our radio boards with no problems. We also conformally coat with a platinum catalyzed, addition cure silicone coating with occassional problems. These silicones are prone to cure inhibition or retard

JD: It's important to note that FR-4 does not contain PBB or PBDE. The bromine in FR-4 epoxy comes in the form of tetra-bromo-bisphenol A [TBBA], which polymerizes and become part of the cross-linked epoxy. Bromine, in the form of hydrogen bromide, i

Bryan: Comments are: * You're correct, solder paste formualtion is a major driver to voiding in BGA balls. * Voids are primarily process indicators. There is experimental evidence that voids retard crack propagation locally around the void on a temp
