Printed circuit boards materials | 12 April, 2004

Can you share some information on the hazardous materials and cleaning details for your manufacturing processes, please ?

These are the questions I need to ask you:

1. Do you use brominated fire retardant in PWB material? If not, what other type of materials do you use instead?

2. Do you use PCB (Polychlorinated Biphenyls)or PCN (Polychlorinated Naphthalenes) as insulation or heat-transfer medium ? If yes, what is the intended usage?

3. Do you use lead-free solder for PWB fabrication? If yes, what type of lead-free alloy do you use? If no, are you planning to implement it? how?

For the summary of a study into flame retardants try: http://www.surrey.ac.uk/PRC/

IVF carried out an international study on alternatives to halogenated flame retardants with 12 major European and Japanese electronics manufacturers and material suppliers. The report covers technical as well as environmental and economic aspects of a shift from brominated flame retardants. A public report of the project "Alternatives To Halogenated Flame Retardants In Electronic And Electrical Products - Results From A Conceptual Study" is available at: http://www.ivf.se/elektronik/Ep/Publications/pub1f.htm
