Alpha Solder Preforms Prevent Die Tilt with Consistent Bondline Thickness

Estimated reading time: 1 minute

Alpha Assembly Solutions is introducing ALPHA TrueHeight Preforms, a solder preform engineered with embedded spacer technology that can address all major applications requiring 75µm bondline and above.

ALPHA TrueHeight Preforms are engineered with simplicity in mind to allow ease of implementation and maximum soldering performance. The architecture of the design not only addresses the bondline thickness requirement, but also reduces the opportunity for voiding.  The design minimizes areas where gases can be trapped, compared to other technologies, during the reflow process.

"Engineers can be confident of achieving their design goals during manufacturing when using ALPHA TrueHeight Preforms," said Eric Poh, Regional Product Manager for Solder Preforms at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. "TrueHeight Preforms have the advantage of flexible spacer positioning, so strategic locations can be chosen to ensure consistent bondline thickness."

ALPHA TrueHeight Preforms can be flux coated as well from a wide selection of fluxes.
