in this issue Circuit Track Repair Kits now Available from BEST Trace and Pad Repair IPC Announces SAC 305 as Lead Free Solder Alloy More RoHs Compliant Circuit Frames Available This month's focus is on PCB repair tools. BEST PCB repair tools are designed using BESTs' combined experience in the area of performing these repairs, instructing technicians on these repair techniques and developing new materials. There are several new developments in the area of PCB repair materials that we are bringing you this month including new circuit frame patterns which we have engineered keeping in mind: RoHS compliance needs Ability to withstand operating temperature and soldering cycles A good repair value We have also added a trace repair kit to the BEST product offering that provides a large variety of trace patterns and the right tools for these type of repairs.   Hope to see you at Assembly Technology! Bob Wettermann, President   Circuit Track Repair Kits now Available from BEST Trace Repair Kit designed to meet the quality of original trace patterns. BEST makes it simple for you to repair damaged circuit traces on printed circuit boards. BEST circuit tracks are ribbons of 99.9% pure CDA 11000 copper with etched backsides that provide a large surface area to adhere the traces to the board. They closely conform to the original conductor dimensions. These replacement circuit tracks are bonded in place using pre-packaged 2-part epoxy included in the kit. This kit is a great time and labor-saver providing the tools you need to quickly repair missing or damaged circuit traces. The method for repairing damaged circuit traces adheres copper circuit tracks to the circuit board. The replaced conductors are the same size as the original. This IPC-approved technique is preferable to making circuitry repairs with jumper wires because it most closely duplicates the original manufacturing process. The BEST circuit track kit is designed for flexibility with (7) different circuit trace widths and thicknesses to accommodate nearly every standard circuit trace used today. Each of the traces as well as the epoxy packs can be purchased individually when the supply from the kit is exhausted. To find out more about the BEST circuit track repair kit   Trace and Pad Repair If surface mount or BGA pads or traces have been damaged due to improper part removal techniques or mechanical "digging" into the circuit board, then BEST can repair these damaged circuit patterns to as a "good as new" condition. If a critical area array device needs to have its pads and or traces repaired prior to reballing then BEST can repair these pads and traces. BEST stocks many different kinds and styles of pads and traces in order to facilitate a fast turnaround of the repair. We even have the ability to make custom traces and pads in order to reduce the time and cost it takes to perform repeat repairs. BEST has a variety of options for your PCB repairs: we can either perform repairs, instruct you in the techniques of those PCB repairs or provide/engineer materials for you performing those repairs at your facility. See one of the repair course outlines at :   IPC Announces SAC 305 as Lead Free Solder Alloy The IPC Solder Products Value Council, in supporting the electronics assembly industry, has now identified a lead-free solder alloy "standard". The Council has helped resolve the confusion regarding alloy choice and has moved the industry towards achieving a worldwide consensus on the issue. The Council will help "standardize" on this alloy, which in turn will reduce costs to the industry, benefiting solder suppliers and users alike. The companies that make up the Council will now devote resources to improving the education, training and support of this alloy throughout the industry.

BEST circuit frames have a variety of advantages over competive frames including: All materials are RoHS compliant and are compatible with both Sn63 and lead-free processes BEST frames are 3x larger meaning they are greater value for your PCB repair dollar They are used with the epoxy method which retains its bond strength even through heating and cooling cycles compared the dry film adhesive technique To see all of our available circuit frames   INCREASE YOUR CHANCES TO WIN NEW HANDHELD PLAYSTATION You can increase your chances to win a brand new PlayStation Handheld game (for the "kids" of course!).
