Circuit board manufacturer: What are aging test-test aging-aging test?


After PCBA processing and production, electronic products must undergo aging tests to strictly control the quality of electronic products before they are sold. This article will separately introduce the aging test, test aging and aging test used before the market of electronic products.


Aging test
The aging test item refers to the process of simulating the various factors involved in the actual use conditions of the product to carry out corresponding conditions to strengthen the experiment on the aging of the product. The experiment is mainly for plastic materials. The common aging mainly includes light aging, damp heat aging, Hot air aging.

 
Test burn-in
As the name implies, the stability of the product is tested by testing its functions. Because the system is in working condition for a long time, load operation of each device during its work, so that its performance can be guaranteed, most electronic products have the aging link, especially in the equipment industry such as electric meters and electricity. Most of the old chemical installations made by Fixion and most of the meter companies are long-term power-on aging, and some power-on up to 96 hours.

Another case of testing aging is to let the equipment operate in an ultra-normal special environment, or let the equipment run beyond the specifications. As long as the performance of the equipment can be guaranteed under these conditions, it will work normally in a normal environment. For such aging, some companies often do some salt spray tests, vibration tests, high and low temperature tests, etc.

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

The aging test is divided into temperature aging, sunlight aging aging, loading aging and so on.

High-temperature aging is generally carried out in several grades. Industrial generally uses a level of 70 degrees, 4 hours, and 15 degrees. Generally, there are 40 degrees, 55 degrees, 70 degrees, and 85 degrees. The time is generally 4 hours.

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

1. Aging box; mainly for plastic products, and products with small quantity and volume are more practical

2. Aging cabinet or aging room; mainly for high-performance electronic products (such as: computer complete machines, monitors, terminals, automotive electronic products, power supplies, motherboards, monitors, switching chargers, etc.) A high temperature and harsh environment test equipment is an important experimental equipment to improve product stability and reliability, and an important production process for various manufacturers to improve product quality and competitiveness. This equipment is widely used in power electronics, computers, communications, Biopharmaceutical and other fields

 
significance
Electronic products, whether they are components, components, complete machines, or equipment, must undergo aging and testing. Aging and testing are not a concept. First burn-in and then test. Electronic products (all products are like this) form a complete product after manufacturing. It can already play its use value. However, after use, it was found that there were such and other problems, and it was found that most of these problems occurred within a few hours to tens of hours from the beginning, and later simply stipulated the aging and testing of electronic products, imitating or equivalent products. , This process is completed by the product manufacturer. After re-testing, leave the problematic products in the factory and give the okay products to the users to ensure that the products bought to the users are reliable.


ipcb is a high-precision, high-quality PCB manufacturer, such as: isola 370hr pcb, high-frequency pcb, high-speed pcb, ic substrate, ic test board, impedance PCB, HDI PCB, Rigid-Flex PCB, buried blind PCB, advanced PCB, microwave PCB, telfon pcb and other ipcb are good at PCB manufacturing.
