We have two major industry leading customers that are driving a lead free process. We have chosen to embrace it, invest in the technology and process and become a regional leader in lead-free process. Like most companies we kept current on the tren

hi, I am a research student in Electronics manufacturing at RIT. We are planning to assemble boards using lead free solder paste. I was wondering would there be any changes in printing in using lead-free paste"Sn-3.9Ag-0.5Cu". Thedensity of Sn-37Pb

Ming- You are correct ACI does have training...and aslo they will be working with the local SMTA for a lead free day on Nov 20th I think. Please contact Jeff Stong at jstong@aciusa.org. They alao have a free session on Nov 4th where Kester and Metcal

I think it is a good idea to "waste" money on this analysis. Especially if you phase in a SAC wave alloy. Silver is not toxicity free....and lead free waves can dross 3 to 5 times faster than SnPb alloys. This produces a greater potential for airb

You may also want to start on the component library. Hypotetically speaking, the GSM shows the component as follows in the component library: One lead to the right, 3 leads to the left. This is the feeder default orientaion and it will be 0 degrees.

A very quick survey regarding PCB finishes for a lead-free process. What is the most popular PCB finish for lead-free soldering ? Who drives the selection of the finish, assembler or designer ? Are tin whiskers an issue for anyone ? I'm coming at th

Hi Ken, It looks like you have some solid practical experience in the transition from leaded to lead-free soldering. I hope you don�t mind me asking a question. With conventional soldering we have a library of workmanship standards available (SMT,

Hi all, There seems to be a problem with the major component vendors/manufacturer everywhere; to supply lead free dummy/daisy chain components, in particular BGA-devices, within a reasonable time (not a big fan of 8-12 weeks). If they got them at all
