There are many factors involved when choosing the components for your board assembly.   Whether it is a consumer, aerospace, down-hole drilling,  industrial, or test boards – At KES, we help our customers by selecting the parts for their Bill Of Materials (BOM) based on their criteria and the application. Here are a few guidelines for anyone designing an electronic product that will help them Read more…

Bert Templeton – June 24, 2020 Bert Templeton – June 24, 2020 The growth of electronics, and along with it, semiconductor content in the automotive industry, continues to climb at a healthy rate, outpacing most other segments. Analyst estimates indicate that the CAGR of automotive electronics will grow at nearly five and a half percent through 2021. That is roughly triple the rate of Read more…

Semiconductor burn-in is a method for detecting early failures in semiconductor devices. This is also called, ‘infant mortality’. It requires the testing of devices under a set of stress conditions that usually involves an elevated temperature of 125° C to 150° C (commonly, some ‘high reliability” device can be tested at 200° C or higher) for a set number of hours. During that time Read more…

HAST BOARD DESIGN GUIDELINES THB and HAST board DESIGN THB (Temperature Humidity Bias) and HAST (Highly-Accelerated Stress) Test boards are used to qualify device packages. These tests are used to evaluate the reliability of non-hermetic packaged devices in humid environments. There are important guidelines that must be followed when designing these types of Burn-In Boards to prevent premature failures in this harsh environment. Below Read more…

The most common types of reliability tests for semiconductors are; burn-in, power temp cycle (PTC), and HAST. Burn-in Burn-in tests check the reliability of the semiconductor device and are typically done at 125ºC or 150ºC, while electrical signals and power are applied to ASICs. Burn-in boards are put into the burn-in system which supplies the necessary power and stimulus to the samples while maintaining Read more…
