SMTA Webtorial: Solder Joint Voids- All You Should Know

Nov 1st + 2nd 2017 1:00pm to 2:30pm Eastern

With the goal to produce reliable products while achieving high yield production, this webtorial provides a holistic overview on solder joint voids. Four fronts in the industry have rekindled the interest and/or concerns about solder joint voids – the lead-free solder joints; the increased use of advanced packages (BTCs, PoPs); the ever-miniaturized electronics comprising “delicate” solder joints; and the increased demand in solder joint reliability for high performance and high reliability products.

Different sources of solder joint voids, their respective causes and effects on the solder joint performance and reliability will be discussed. The practiced acceptance criteria of solder joint voids vs. real-world performance, and the steps to minimize solder joint voids of both the array solder ball solder joints (e.g., PoP, BGA, CSP) and lead-frame solder joints (e.g., QFP, BTC) will be outlined. The webtorial will conclude with the source of voids that is most critical to reliability, thus to avoid
