BEST personnel are continuing to bring together information and resources on PCB rework, repair and electronics assembly. This month we are debuting several resources for you to use with respect to PCB repairs. In this issue of our newsletter we will show you where to find the beginning of our library of PCB repairs. In this added section of the BEST web site (www.solder.net) you can find a brief process description of the repair procedures and examples of BEST professional repairs. BEST will be active in presenting its capabilities in July at a Chicago area Imbedded Systems conference (see registration link below)
Wishing safe travels this summer!

BEST Finalizes Lead Free RoadmapThe BEST team has been busy formalizing its lead free implementation roadmap outlining how we will respond to lead-free service work, how we will instruct on lead-free processes and how we will deal with lead-free product requirements.
BEST has been responsive to the beginning "wave" of customer requirements for working on lead-free circuit boards. The services that have been impacted the most due to lead-free implementation are rework & repair services and prototype builds. The elimination of tin/lead solder is beginning to be demonstrated by the type of rework, repair and prototype builds worked on by BEST.
BEST is and will continue to be providing lead free processing services for three groups of customers: those that require rework of assemblies manufactured with tin/lead solder, those that require rework of assemblies with both tin/lead and lead-free solders and those that require rework of assemblies with lead- free solder only. Our lead free roadmap defines how we will tightly control the process and materials for each of these customer types. To see the BEST lead free roadmap
Gold fingers are prone to damage as they are on the periphery of the circuit board. In addition, they are prone to solder splash during the wave soldering process. When edge contacts are contaminated with solder, get scratched, torn or are damaged, BEST repair technicians can bring them back into specification. These contacts can either be replaced or repaired. Our repair methods will restore your edge contacts to their original level of performance and reliability. BESTs' highly skilled technicians can repair the gold fingers thereby eliminating the need to scrap the entire board. We have custom gold finger fabrication capabilities for those higher volume repair jobs in order to minimize the turn-around time and keep repair costs to a minimum. BEST now has a fixed gold finger repair price of only $15 regardless of the number of goldfingers needing repair! Call for more details.

BEST is one of the first training centers to offer 610D instruction for both operators and instructors. BEST master instructors were not only part of the beta training program but were actively involved in the committees responsible for rewriting the document.
There have been extensive changes to the IPC A-610 with the launch of the D revision. The document has been reformatted in order to make it more user friendly for those employing the criteria on the manufacturing floor as well as for instructors teaching the requirements. Many criteria have also changed. Significant changes in the following areas are adressed in 610 REV D: Lead Free Visual Appearances, BGA and MELF inspection and more! To See the Course Schedule
Are you looking for a good resource which describes the BGA rework process? BEST has recently added a process flow description of the various BGA rework process steps. Issues related to paste printing versus flux only attachment, site dressing and profile determination are detailed. Also included are the methods for handling , packaging and inspecting BGAs practiced by BEST. BGAs.
