Alpha Intros New Liquid Soldering Flux for PV Tabbing and Stringing Applications


Reading time ( words)

Alpha Assembly Solutions is introducing ALPHA PV-38i, its newest liquid soldering flux for PV tabbing and stringing. ALPHA PV-38i is a zero-rosin, no-clean flux specifically designed to meet the demanding requirements of the photovoltaic industry. This tabbing and stringing flux has the lowest solids formula (1.10%) available in the industry.

"ALPHA PV-38i employs a unique proprietary activator system that limits pollution inside tabbing and stringing equipment and spray nozzles, with practically zero residue present after soldering," said Mike Previti, Global Product Manager for Flux at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. "This formula also allows an extended shelf life versus many other competitive fluxes in the industry."

In addition, the unique chemistry of ALPHA PV-38i provides excellent soldering with fast wetting in standard module assembly processes, employing widely used methods (preheat and soldering) for both spray on cell or dip applications.

PCB Pad Repair Techniques

01/08/2018 | Bob Wettermann, BEST Inc.
There are a variety of reasons behind pads getting "lifted" completely or partially from the laminate of a PCB. Per the just revised IPC-A-610 Revision G, a defect for all three classes occurs when the land is lifted up one or more pad thicknesses. Lifted pads can occur when a device has been improperly removed or there is a manufacturing defect in the board construction. In any case, as with any repair, the ultimate decision on the ability to repair the pad lies with the customer.

The Effect of Area Shape and Area Ratio on Solder Paste Printing Performance

12/28/2017 | Stefan Härter, et al.
The ongoing miniaturization trend in the SMT production induces new challenges and highly integrated systems. In passive components, the miniaturization leads to the introduction of the EIA size 01005 or smaller. Despite numerous publications in this field already addressing the printing of such devices, a defined wholly optimized process remains unsolved and inspires further novel research ideas on this topic.
