ALPHA® AccuFlux™ BTC-578 Preform

ALPHA® AccuFlux™ BTC-578 Preform System is a proven method for solving voiding issues under bottom terminated components (BTC). As power requirements for BTCs are increasing, component manufacturers are designing device packages that require less voids to ensure they work as intended. New BTC components require less than 25% voids after the reflow process. 15% or even less than 10% voids are required to ensure proper function and reliability. Recognizing this trend, Alpha developed a low voiding Preform System that addresses the challenges head-on using your existing equipment and process.
