What Is a Laser Diode

A laser diode falls under the category of optoelectronics which is a branch of electronics that deals with light-emitting and light-detecting devices. A laser diode is a special LED or IRED with a relatively large and flat P-N junction. How a Laser Diode Works Laser...

Wafer Level Burn In & Test

Wafer-level Test and Burn-in (WLTBI) refers to the process of subjecting semiconductor devices to electrical testing and burn-in while they are still in wafer form.  The increasing complexity of SoC (System on Chip: commonly known as an “IC” or “chip”) has placed...

Burn-in Board for Reliability Testing

Semiconductor equipment that test and screen out early failures during the “infant mortality” stage are put on a board known as “Burn-in Board”. On a burn-in board, there are multiple sockets to place the semiconductor device (ie. laser diode or photodiode). The...
