Pre-shipment inspection of electronic products
Electronic products are being updated very quickly. For consumers, they all want to buy safe, reliable and high-quality products. Any brand to win a larger market share, the first thing to do is to do a good job of quality control, followed by style, price and other factors. So, as a third party inspection agency, how do we conduct pre-shipment inspection of electronic products?
The first is environmental reliability testing, which refers to the ability of a product to perform a specified function under specified conditions and within a specified time. In the process of using the product, it needs to withstand the influence of itself, the external climate environment and the mechanical environment, and it also needs to ensure that it can work normally, which requires testing equipment to test it.
1. The external climate environment includes: high temperature, low temperature, alternating high and low temperature, high temperature and high humidity, low temperature and low humidity, rapid temperature changes, temperature shock, high pressure cooking (temperature rise), salt spray corrosion, gas corrosion, welding heat resistance, tin, dust and waterproof (IP class), flame retardant testing, UV aging, light aging, and so on;
2. Mechanical environment includes: vibration, mechanical impact, mechanical impact, drop, inclined impact, temperature and humidity + vibration, high accelerated life test (HALT), high accelerated stress screening (HASS), insertion and withdrawal force, retention force, insertion and withdrawal life, wear resistance test, adhesion test, hundred grid test, etc.
3. The product itself needs to solve the problems of contact resistance, insulation resistance, voltage resistance and so on.
Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC has two requirements: On the one hand, the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it means that the appliance has a certain degree of anti-interference ability to the electromagnetic interference in the environment, namely electromagnetic sensitivity.
Safety regulations refer to the requirements for product safety in product certification, including the safety requirements of product parts and the safety requirements after the composition of the finished product. It includes a product safety responsibility and activity throughout the product life cycle from design to sales to the end user.
