1. Quality control

Quality control of automotive electronics is an important step in ensuring product quality and factory productivity.Take the reflow oven as an example,although the oven temperature control system and temperature sensor can be used to control the furnace temperature,but the actual temperature of the PCB solder joint is not necessarily equal to the default reflow temperature.Although the reflow machine is working properly, the temperature control is also within the temperature control accuracy of the device.However, due to the PCB board quality, assembly density, the number of PCB into the furnace and other uncontrollable factors, the temperature curve will be the corresponding fluctuations.

2. Technical requirements of quality control

Quality control requires that technicians have good measurement knowledge, statistical knowledge, causal analysis capabilities, and a deep understanding of equipment performance.The variables in the production line exist.Equipment aging, personnel adjustments, the quality of materials, etc., will affect each other, contain each other, so that the quality of automotive electronics products have fluctuations.Therefore, under the premise of without affecting the production and increase production costs,it is very difficult to adopt effective and continuous quality control methods.

3. Quality control methods

At present, in the automotive electronics manufacturers, the introduction of advanced testing equipment used to monitor the quality of the production process.

In the reflow process, the general use of AOI testing equipment for quality control.

Automatic parameter adjustment and due to the high cost, manual setting is also required.In this case, the need for automotive electronics assembly enterprises to develop some effective norms and systems,strict implementation of the development of norms, through the manual monitoring to achieve the stability of the process.

Automotive electronic processing price of quality control specification formulation, the operator's ability to respond and precise control of equipment is very important.
