ALPHA® Solder Preforms


ALPHA® 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.


LEADED

Eutectic SnPb has been used as a joining material for generations. Today, with the material being banned in almost all soldering applications due to the lead free legislation, it can only be found in some niche assemblies such as for those in the Military, Aerospace and to a smaller extent, Automotive. Choose from Alpha's range of cleanable and no-clean chemistries and be assured of the highest performance standards in a leaded solder paste.

LEAD FREE

While SAC305 is the alloy of choice generally adopted by the electronics industry, the lead free legislation spawned an entire list of alloy options that Alpha Assembly Solutions continues to offer to meet the variety of customer needs. Our range of low silver alloys (SACX+ 0307) to the higher silver ones (SAC405), as well as the more specialized alloys such as Innolot and Maxrel+, will cover all your lead free performance needs. Available in cleanable and no-clean chemistries to meet all the needs that a modern solder paste product requires.

LOW TEMPERATURE

Low temperature alloys have traditionally been associated with low performance low cost assemblies. That is now changing with customers wising up to the multiple benefits of low temperature soldering. Find out more about Alpha's high performing range of low temperature solder pastes and stay ahead of the competition.

SPECIAL APPLICATIONS

Alpha's preforms can also be made with other alloys such as copper. Trueheight spacers can be used to provide additional clearance beneath area array components such as LGA and LCS to prevent excessive bondline tilt during reflow resulting in bridging.
