A product is composed of various resistors, capacitors, and ICs. Burn in chamber can not only test the stability of the product, but can also detect defective products.
LED modules, computers, monitors, display cards, and TVs are the product that is currently doing Burn in process. Over a period of time, the defect rate of electronic parts will drop to a stable quality close to zero.
Burn-in process in Sander is generally used in products that require a long working life, such as LED modules, computers, display cards, etc.
Sander is well-equipped with professional burn-in chambers, which can set the ambient temperature to 60-80 degrees, and uses thermal circulation to heat the electronic parts of the product evenly. After the burn-in completed, the finished products will be tested again to ensure that the products operate normally under regular temperature.
However, burn-in is not necessarily required for all products. Take control boars for example, if there are functional error, using relevant test fixture and correspondbning test software could find out the cause of the failure.
Burn-in chamber can filter out the undesirable electronic parts, and can also detect some solder problems such as empty soldering, cold soldering, and false soldering that occur in the process.
Some products might consist parts of different brand and manufacturers, and unexpected functional errors might occur. With burn-in examination, we can make sure the performance quality of each product before we ship to our customers.
However, there’s higher cost for adding the burn-in process. With extra use of electricity, time, and manpowers. Not only prolongs the production time, the overall cost would also be higher.
