PCB Technical - What is PCBA aging test?

What is PCBA aging test introduced by PCBA manufacturer today?

After processing and production of PCBA, electronic products must undergo aging test before sale to strictly control the quality of PCBA. Now iPCB introduces the PCBA aging test and aging test used before electronic products are launched.

PCBA aging test

The aging test project refers to the process of simulating various factors involved in the actual use conditions of the product and carrying out corresponding conditions to strengthen the aging test of the product. This experiment is mainly aimed at plastic materials. Common aging mainly includes light aging, damp heat aging and hot wind aging.

PCBA aging test

The stability of the product is tested by its function. Because the system has been in working condition for a long time, the PCBA of each equipment has load operation during the working process to ensure its performance, so most electronic products have aging links, especially in the equipment industry such as electricity meters and power. Most of the old chemical devices manufactured by most instrument companies are aged after being electrified for a long time, and some devices have been electrified for 96 hours.

Another case of PCBA aging test is to allow the equipment to operate in an abnormal special environment, or to allow the equipment to operate beyond the specification. As long as the performance of the equipment can be guaranteed under these conditions, it will work normally under normal conditions. For this kind of aging, some PCBA companies often do some salt spray tests, vibration tests, high and low temperature tests, etc.

PCBA aging test

It mainly refers to the thermal oxygen aging test of rubber, plastic products, electrical insulation materials and other materials; Or ventilation aging test for electronic parts and plastic products.

The aging test is divided into temperature aging, sunlight aging, load aging, etc.

High temperature aging is usually carried out in several grades. The industrial temperature is usually 70 ℃, 4 hours and 15 ℃. There are usually 40 degrees, 55 degrees, 70 degrees and 85 degrees. The time is usually 4 hours.

According to the quantity of aging test products, the test is divided into two methods

1. PCBA aging box; Mainly used for plastic products. Products with small quantity and volume are more practical

2. Aging cabinet or aging room; It is mainly used for high-performance electronic products (such as computer complete machine, display, terminal, automotive electronic products, power supply, main board, display, switch charger, etc.). High temperature and harsh environment testing equipment is an important experimental equipment to improve the stability and reliability of products, as well as an important production process for various manufacturers to improve product quality and competitiveness. The equipment is widely used in power electronics, computers, communications, biopharmaceuticals and other fields.

Significance of PCBA aging test

Electronic products, whether components, components, complete machines or equipment, must undergo aging and testing. Aging and testing are not a concept. First aging, then testing. Electronic products (all products are like this) form a complete product after manufacturing. It can already play its use value. However, after use, it is found that there are such and other problems, and most of these problems occur from a few hours to dozens of hours at the beginning. Later, it simply stipulates the aging and testing of electronic products, imitations or equivalent products., This process is completed by the product PCBA manufacturer. After the retest, the defective PCBA products will be left in the factory and the qualified products will be handed over to the user to ensure that the PCBA products purchased to the user are reliable.
