Paul, I did a search using all three words "double sided reflow" in the archives and found 120+ postings, on both separate and simutaneous double reflows. Please repeat the search and let us know whether you find what you want. Thanks, Cunli

Bill, As Cunli said, there is a link at the top of each message page that will pop open a printer friendly version. Before we added that feature, the only solution was to print the page in landscape mode. The printer friendly version is not a fixed

Mike - I had tried the "printer friendly version" before I sent my original message last Friday. The result may have been "printer friendly", but it wasn't very "reader friendly". All the words printed but the printout removed all the formatting so

We're try to stay away from using electroless nickel. Please describe the differences between the IMC.

Lead Free Ball Grid Array packages are expected to be increasing the shipment numbers by 2006. How many guys out there are familiar with the lead fee BGA's and the associated processes? Can some one tell me who is the best and low cost supplier for t

Currently, we see lead-free solderballs on BGA. The issue for us is determining the reliability of these components when using leaded solder. Most solder materials manufacturers supply lead-free solder balls. Check with your current solder paste s
