How To Identify Common Electronic Failures


Failure analysis is the process of identifying, and typically attempting to mitigate, the root cause of a failure. In the electronics industry, failure analysis involves isolating the failure to a location on a printed circuit board assembly (PCBA) before collecting more detailed data to investigate which component or board location is functioning improperly.

Using Digital Image Correlation To Determine BGA Warpage


Digital image correlation (DIC) is a non-contact, full-field displacement, optical measurement technique. It is often used in the following applications: Material characterization Coefficient of thermal expansion (CTE) Glass transition temperature Young’s modulus Poisson’s ratio Sample testing for fatigue and failure In situ monitoring of displacements and str... » read more

Reliability Of Embedded Wafer-Level BGA For Automotive Radar Applications


With shrinking of chip sizes, Wafer Level Chip Scale Packaging (WLCSP) becomes an attractive and holistic packaging solutions with various advantages in comparison to conventional packages, such as Ball Grid Array (BGA) with flipchip or wirebonding. With the advancement of various fan-out (FO) WLPs, it has been proven to be a more optimal, low cost, integrated and reliable solution compared to ... » read more

Wirebond Technology Rolls On


Several years ago, many predicted the demise of an older interconnect packaging technology called wire bonding, prompting the need for more advanced packaging types. Those predictions were wrong. The semiconductor industry today uses several advanced packaging types, but wire bonding has been reinvented over the years and remains the workhorse in packaging. For example, Advanced Semiconducto... » read more

Inside Advanced Packaging


Semiconductor Engineering sat down to discuss advanced IC-packaging, the OSAT industry, China and other topics with Ron Huemoeller, vice president of worldwide R&D at Amkor. What follows are excerpts of that conversation. SE: Where are we in advanced IC-packaging today? Huemoeller: We’ve hit the inflection point. Now we are coming to the other side of it. Regarding this need to int... » read more
