Description
ALPHA ExactAlloy Solder preforms- for the Automotive Industry
ALPHA ExactAlloy Solder preforms are used in industries ranging from PCB Assembly, stand-alone industrial applications, and high-end power semiconductor packages. The breadth of the product line includes fluxed and un-fluxed rectangles, washers, sleeves, and custom shapes for specific applications. An all-encompassing alloy portfolio includes standard assembly alloys, high reliability alloys, and low melting point alloys. The use of tape and reel packaging offers ease of implementation into standard SMT manufacturing lines.
Preforms can also be used as a means of eliminating wave soldering. For example, in most automotive electronics assembly wave solder exists solely to solder connectors onto the PCB, as the rest of the assembly is now produced with the SMT reflow process. Concerns about achieving acceptable holefill prevent the user from eliminating this extra soldering stage, even though wave is often the cause of most defects and reliability hazards. Most connectors are now available as reflow capable, which enables the reflow soldering of these devices, thus eliminating wave soldering. 100% hole fill is routinely achieved with a wide variety of pin and hole ratios, even for thick PCBs, by the use of “Tape and Reel” delivered Preforms. These Preforms complement the printed solder paste to provide adequate and predictable solder volume for reliable through-hole connector attach in Automotive Electronics.
