Increasing The Conductive Density Of Packaging


Wide bandgap (WBG) semiconductor technologies have created new challenges and opportunities for power packages. Developments such as silicon carbide (SiC) and gallium nitride (GaN), have a higher figure of merit (FOM) compared to silicon MOSFETs and have extended the efficiency, output power and/or switching frequency range and operating temperature range for power electronics. With lower lo... » read more

A Look Inside ADAS Modules


You glance down at your phone while rolling in slow-moving traffic. Against your better judgment, you proceed to read your latest email, oblivious to the fact that the car in front of you has braked. In the nick of time, your car starts beeping and flashing. You look up and slam the brakes. Whew! That was close. If this has happened to you, don't forget to thank the radar and camera modules in ... » read more

Adding Value With Unit Level Traceability (ULT) In Automotive Packaging


Automotive product traceability has existed in one form or another for several decades. Traceability generally refers to tracking and tracing each component that comprises every sub-system in a car. Traditionally, this has been achieved with direct part marking on mechanical or electronic components, using 1D or 2D barcodes or radio-frequency identification (RFID). Since vehicle recalls are cos... » read more
