Feb 2014

Dear Electronics Colleague:

February has been a great month with the Olympics and other adventures. Our family had the opportunity to visit a local 50m ski jump (what in Illinois?!) to see some of the regional competitors. It included kids jumping since they were 5 years of age. In addition, we had the opportunity to go night snorkeling with Manta Rays having a 14ft wing span while in Kona, Hawaii.

BEST staff and outside SMEs are in the midst of planning for our April 3rd X-Ray Workshop. It will feature Bob Klenke and Ken Gribble-both industry veterans, and long time speakers on X-Ray and other SMT topics. Contact info@solder.net to get one of the slots left.

Wishing a Healthy and Successful New Year!

Rework of Bare Boards

Before Ablation Before Solder Mask Ablated

BEST and Additive Circuits (NH) are combining their collective expertise to bring you the capability for bare board rework. If you need to have traces cut, pads added, solder mask ablated, boards machined to exacting specs or conductors added; then BEST can be your source. We can quickly modify existing boards eliminating the wait on a board re-spin, and scrap out of many existing boards that are unusable.

BEST brings technology in highly precise laser cutting and ablation, while Additive Circuits has proven technology in conductor modification that allows for subsequent SMT assembly processes to be completed to the PCB.

Call Laura Ripoli at (847)797-9250 or email her your modified GERBER files at lripoli@solder.net to see how we can be of service.

BEST Develops Tools for EZReball(TM) Preforms

BEST has developed a few more useful tools to make your job of reballing simpler and faster.

Firstly, a pair of "square off" angles help to align the preform and the device. Unlike other devices they do not impact the thermal mass of the assembly. Simply square the preform to the device on opposite corners, remove and then place the device/preform "sandwich" on a plate of ceramic or glass and reflow.

Secondly, BEST Inc can configure a weight for the preform when the warpage of the BGA/CSP or WLP is distorted.

Contact Katy Radcliff at kradcliff@solder.net or call (847) 797-9250 if you want to make your reballing simpler and faster with these tools!

We can be the Referee

BEST can be your "referee" resource when clarification is required regarding a PCB or wire harness acceptance standard interpretation. Our Master Instructors, who are military trained and have been Master Instructors for the IPC-A-610 courses for many years, can provide a "third set of eyes" when an issue arises in the PCB assembly process. We can provide a detailed report for refereeing purposes. BEST is available when you need an outside expert opinion, or when you need to determine the existence of aPCB assembly process problem. If you need assistance, call Laura Ripoli at (847) 797-9250.
