Semiconductor Random Failures
Engineers and scientists have studied failures so often that they now have models, or equations, that we can use to predict when failures will occur. These models don’t forecast if a distinct semiconductor device may fail, but they can forecast with confidence the...
Semiconductor Wear-out Failures
Semiconductors fail whenever they hit the capabilities of their basic durability. This period is named the region of wear-out failures, and reveals the life of various failure modes of semiconductors. Wear-out failures differ with variations in the stresses applied to...
Burn-in Testing
Burn-in testing is the process by which a system detects early failures in semiconductor components (infant mortality), thereby increasing a semiconductor component reliability. Normally burn-in tests are performed on electronic devices such as laser diodes with an...
Laser Diode Reliability
The majority of semiconductor device reliability modeling is done using the exponential probability distribution model, which assumes the semiconductor has a constant failure rate and there is no wear-out mechanism. However, there are a number of factors which affect...
Why product reliability is so important
We expect our cars, computers, electrical appliances, lights, televisions, etc. to function whenever we need them - day after day, year after year. In today's technological world nearly everyone depends upon the continued functioning of a wide array of complex...
Laser Diode LIV
Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (LIV) measurements during production. These measurements let you characterize a laser diode's light output and forward voltage as a function of input current. Testing a...
HALT Testing
Learn more about our various reliability testing services including our HALT Testing Services. The article below explains the process of HALT and why it is important. Highly accelerated life testing (HALT) is a method used to test solid-state electronics and determine...
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...
