MTBF Calculation
MTBF Calculation & Product Reliability MTBF is commonly confused with a component’s useful life, even though the two principles are not related in any way. For example, a battery may have a useful life of four hours and an MTBF of 100,000 hours. These statistics...
How Semiconductor Microchips Are Made
Silicon microchips are produced in a process that's a combination of the familiar and the weird. Some facets are as familiar as creating a photograph in a dark room, whereas many others are like space exploration or subatomic physics. In the end, it all comes together...
FIT (Failure in Time) Calculation
Failure In Time (FIT) is another way of reporting MTBF. FIT reports the amount of expected failures per one billion hours of operation for a device. This term is used particularly by the semiconductor industry it is also used by component manufacturers. FIT can be...
Mean Time To Repair (MTTR)
Mean Time to Repair Mean Time To Repair (MTTR) is the time needed to fix a failed component or module. In an operational system, repair always means upgrading a failed component or device. MTTR could be seen as mean time for you to replace a failed equipment module....

Early Semiconductor Failures
A semiconductor device usually fails mainly because experiencing situations that stress the semiconductor past its maximum ratings. The means a device stops working is known as a mechanism failure. Typically, electricity, heat, mechanical stresses, and other factors...
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 Tester: Reliability & Test Equipment Burn-in testing is the process by which a system detects early failures in semiconductor components (infant mortality), thereby increasing a semiconductor component reliability. This burn in process is a vital testing...
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
