Lead Free BGA Study Results Now Available

Recently BEST commissioned a study which compared the reliability of various lead-free BGA rework methods. The results were presented at the recent Pan Pac Exposition and at APEX. They are now available in both their presented paper form as well as in the lab test results version.
This study was commissioned to compare paste printing and flux only rework attachment methods and the impact that they would have on the reliability of lead-free processed BGAs. Each of the samples were tested for the reliability of their interconnections as they were subjected to 1,000+ temperature cycles.
The results of this study showed:
First pass rework yields of flux attachment are lower than solder paste printing
The reliability of lead-free reworked BGAs is not impacted by the presence of the StencilQuik(TM) stay-in-place stencil

ONLINE A610 Recertifications

BEST has available IPCA-610 CIT and CIS re-certifications without ever having to leave the comfort of your home or office. It is easy to use and little computer expertise is required! These online re-certifications offer:
The elimination of travel for the testing:
The flexibility of taking the test wherever you want
The ability to have students test at various times so as not to dedicate a trained, skilled soldering trainer for re-certifications
Please find attached a link to the demo sight for the A610 recertification. Just click through to see what the interface would look like for your students. Both CIS and CIT re-certifications are available. Follow the link below to see an online recert demo!

MLF, QFN and LGA Rework and Placements

BEST has had numerous experiences with leadless device initial placement and rework. We have the right experiences and the right tools for the job.
The key to successful LGA, QFN and MLF rework is the proper solder paste printing of the land areas. BEST has the experience to properly design the stencils, even when large ground planes exist on the device. In addition, our technicians can "bump� the device lands using the StencilQuik(TM) stencil printing technique.
We have gathered a variety of resources on our web site so that you can learn more about the placement and rework of these package types. See the link below......
