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

There is no specification for lead-free HASL. You can use any lead-free solderability protection that meets your customer requirements. Use IPC-9701 �Performance Test Methods and Qualification Requirements for Surface Mount Solder Attachments� to ass

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

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

We're unaware of any such reaction. The RoHS Directive bans the use of six hazardous materials. The materials are four metals: lead, cadmium, hexavalent chromium, and mercury; and two brominated flame retardants: polybrominated biphenyls (PBB) and p

Hello everybody, are this the values still required by RoHS or there have been some modification ? - Maximum concentration Lead (Pb) 0,1 weight% - value of heavy metals Mercury 0,1 weight% - Cadmium 0,01 weight% - Chromium VI 0,1 weight% - Maximum
