'Can Do' in CAM Outsourcing

Time-to-market has been the mantra for every successful technology company. The best among them have strong and integrated supply chains that march to the drum of the OEMs and EMS providers that bring that technology to market. A big part of that success, especially in North America and Europe, is the ability for PCB manufacturers to turn around complex PCBs very quickly. The hallmark of PCB production in these higher-tech, higher-cost regions is flexibility and responsiveness.

Whose Fault is That Bad Board?

Years ago, I held a position in an EMS company where projects were analysed before manufacturing. We found that even some of the best and most innovative circuits could not be manufactured. Why? Because the PCB designer, an electronic engineer, was not acquainted with the fabrication process. He had no idea about technological requirements necessary for electronic production. I know another designer who learned, finally, the importance of the thermal relief pad for heat restriction during reflow for a good soldering. His response? “Oh, was that what they were for? And to think I worked so much to remove them!”

I went to my second IMPACT Washington, D.C. event this year (May 1–3) and, as much as I applauded last year’s event, this one far surpassed it—just ask anyone who was there. In this month’s issue, a special section on IMPACT backs that claim.

Mr. Laminate Tells All: PTFE is About to be Banned by IEC TC111

There, I said it. Technical Committee 111 of the International Electrotechnical Commission (IEC) is preparing to effectively ban PTFE (polytetrafluoroethylene) materials from electronics. As history goes, the electronics industry has focused on only two of the four halogens (bromine and chlorine) to be limited in order to be called “halogen-free” or more accurately “low-halogen.” But now, fluorine is being dragged down too, just because of its location in the periodic table.
