What is a Photodiode
The job of the photodiode to convert the light energy received from the laser diode into electrical energy. Photons absorbed by the photodiode excite electrons within the photodiode in a process called intrinsic absorption. When stimulated with an outside bias...
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 Chamber
A burn-in chamber is an environmental oven used to evaluates the reliability of multiple semiconductor devices and performs large capacity screenings for premature failure (infant mortality). These environmental chambers are designed for static and dynamic burn-in of...
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...
