Major Japanese OEMs investigated numerous lead-free alternatives, including alloys containing bismuth and/or zinc, such as Sn/Ag/Bi/Cu, Sn/8Zn/3Bi and Sn/58Bi. However, over time, the Japanese industry has moved toward Sn/Ag/Cu alloys. The Japan Elec

I've been an electronics hobbyist for many years (almost 50!, that's scary), and I'd like to expand my "skills set" to include being able to work with SMT components. I know I'll need some sort of magnifying viewer, 35x has been suggested. I'll also

It's driven by those highly technically astute politicians in Europe. IPC has a lead-free forum you can subscribe to and almost to a person in the forum agrees that elimination of lead in solder is assinine. From the automotive end of electronics

I'm not a politician but it sure looks like protectionism and a short-term economy boost for Europe. Don't forget that lead-free for the electronics is a European directive, USA and other countries (exept for japan) have non of this on there agenda (

We�d say that it�s incorrect that ENIG solderability protection cannot be steam aged. It�s true the immersion tin and silver cannot be steam aged. We believe that most of the issues surrounding the poor performance of ENIG after steam aging is attr

3) There are several papers on the safety of cleaning PCBs and ICs using ultrasonic technology. The latest is in the October 2004 issue of SMT magazine by William Kenyon, "Why Not Ultrasonics?" Most of the studies have been performed by Dr. B.P. Ri

Regarding the reference (Patrick) to a previous thread promoting �no-residue� fluxes, I must say that there is absolutely no such thing as �No-Residue� flux. There are �Low-Residue� fluxes and even �Very-Low� residue fluxes but to suggest that there

We are attempting to increase utilization of our Pick and Place equipment (MY9) by transfering more components into the SMT area. Large gains could be had if we can successfully place a metal socket with a lipped pickup surface into a circuit board h

Hi Steve- We have a Glenbrook system and are pretty pleased with it....as far a value vs. cost it works great. I did have an issue with a Soic with a ground plane in the center...yes SOIC!!! The Ground plane was a heat sync that had vias for thermal

Hello All, Can somebody direct me to a facility or school or even a business that can offer an x-ray course for Class 3 electronic circuit board population interpretation, as in BGA ball acceptance, connector solderability fill acceptance etc.? Some
