Component quality inspection: It can determine the quality of resistors, capacitors, inductors, transformer and transistors
finished product test
Completely inspect and test the finished product before packing.
1- The oscilloscope can directly display the signal waveform and measure the instantaneous value of the signal.
2- Measure the operating voltage of the electronic circuit or component and compare it with the normal value to judge the fault
Aging test 8-10 hours before packing, ensure the quality of the product is qualified before packing.
The most important function of PCB soldering is to weld all the components together and let them play their roles. The solder joints and the protection component solder joints are not oxidized and dropped off.
Assemble the components according to the specified technical requirements, after debugging and inspection to make them to be qualified products.
4- Test amplifier indicator light
3- Test amplifier power supply board
Finish all the tests and waitting for clean up.
In accordance with the specified technical requirements, workers join several parts into components carefully.
semi finished product test
Ensure effective control of product quality.
2- Test output and input board
Use a thick cardboard box and foam to make transportation without problems.
