This type of PCB testing technique is very effective and allows you to check the performance and identify defects in a PCB in real time environments. In case, the temperature is very high in the range of 300 ☌, then high grade polyimide material is the best match. For temperatures as high as 250 ☌, the polyimide material is used. If higher temperatures are to be applied then other material is used. A special version of flame retardant or FR4 material (High Tg FR4) for making the board capable of handling temperatures of 125 ☌.

Thus, high-grade materials are used in these boards. What are the Materials Used for Burn in Boards?īurn-in boards are exposed to high temperatures during testing. Special sockets are provided on the burn-in boards for the purpose of fixing the ICs in them. Components, such as ASICs are installed on these boards to test. The burn-in boards are special types of boards that are mainly used for carrying out burn-in testing. What are burn-in boards? The next section explains this. The technique is most commonly carried out with burn-in boards. This helps ensure whether they have passed the oven testing or not.

Once this stress test is done, the samples are screened. The samples to be tested are supplied with the necessary voltage. Also, during the process, these boards are put in a burn-in oven. Temperatures as high as 257 ☏ (125 ☌) are maintained in the process. The boards are capable of surviving the high temperatures in the testing process. This helps in identifying the defects and failures. This helps ensure the reliability of the components, as well as the PCB.ĭuring the burn-in testing, the ICs placed on the board are subjected to immense stress. In this testing method, the components are stress tested. The testing is performed when power and electrical signals are applied to these application specific ICs.īasically, this technique is carried out with different components before they are used. This method of testing is generally carried out at 125 ☌ (257 ☏).

The reliability of the ASICs is checked by performing the burn-in testing technique. This where, the burn-in testing comes into play. Therefore, it becomes a very critical and intricate task to test these circuits on a printed circuit board. Here’s the answer –Īpplication Specific Integrated Circuits (ASIC) are a kind of specially designed ICs for specific applications – as their name suggests. What is Burn-in Testing Exactly?Ī very basic question. The answers to this question and a detailed account of burn-in testing lie in this post. What is this method? How are circuit boards tested with this technique? All these questions must be popping up in your mind.

Out of the several testing and inspection techniques, one is the burn-in testing method. Thus, if at all any defects are present, they can be eliminated at the earlier stages of manufacturing. This helps ensure the quality, and functionality of the manufactured PCB, along with checking it for any defects. During the printed circuit board (PCB) manufacturing, different types of testing and inspection processes are carried out.
