What is the difference between the IC test socket and the burn-in socket that we often talk about? I believe that many of my friends don’t know it very well. The editor of Hongyi Electronics will explain to you the following explanation with an inappropriate metaphor: /p>

The aging seat is like a person (chip), lying in bed, one sleep may be 100 days. I get up after 100 days (the spring is deformed for a long time), and the 1,000 springs on all beds need to bounce back to their original positions, the ones that are not high, and the ones that are low are deformed. The test seat is like a hotel bed, for 30 days, it may sleep 30 different people (chips). Sheets (contact points) will be worn by guests, and the art of plating on contact points (wear resistance) is important. In theory, the cost of the burn-in block is more expensive than the test block. The burn-in seat is made of beryllium copper, and the test seat is made of phosphor bronze. The metal characteristics and price of beryllium copper are better and more expensive.

Can the burn-in seat be used for testing purposes?

Testing is only one of the many functions of the burn-in block, and it is overkill to use only the test block. However, if you use the test socket for aging purposes, you may find yourself bitter! In addition to the test socket, other parameters are also considered.

The test generally refers to the normal temperature, but aging, usually need to consider the high temperature, low temperature, humidity, salinity test and long-term test heat dissipation effect. How much temperature is the plastic resistant to deformation or burning!

Aging base—a base that can be tested in harsh environments. The burn-in seat determines whether a certain chip is designed, whether it can be said that the design of a chip is good or not, and the chip cannot be blamed because the chip is in poor contact with the test pin! It may be tested in harsh environments such as high or low temperature for 3 consecutive months. Decide the fate of the chip (newborn). Or whether certain chips can go into space or make airplane parts.
