Power Amplifier Production Process
A power amplifier, which consists of thousands of parts, the quality of the parts, and the details of the production process,
determines whether it is an excellent power amplifier. Our mission is to carefully manufacture each amplifier
so that it fits perfectly with every performance of the customer.
     

1. COMPONENTS TEST
Component quality inspection: It can determine the quality of resistors, capacitors, inductors, transformer, and transistors.

2. WELDING
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.

3.COMPONENTS ASSEMBLY
In accordance with the specified technical requirements, workers join several parts into components carefully.


4. SEMI-FINISHED PRODUCT TEST  to ensure effective control of product quality.
4-1. Test amplifier board
4-2. Test output and input board
4-3. Test amplifier power supply board
4-4. Test amplifier indicator light


5. PRODUCT ASSEMBLY
Assemble the components according to the specified technical requirements, after debugging and inspection to make them to be qualified products.

6-1. FINISHED PRODUCT TEST
Completely inspect and test the finished product before packing. The oscilloscope can directly display the signal waveform and measure the instantaneous value of the signal.
6-2. Measure the operating voltage of the electronic circuit or component and compare it with the normal value to judge the fault.


7. AGING TEST
Aging test 8-10 hours before packing, ensure the quality of the product is qualified before packing.

8. FINISHED PRODUCT
Finish all the tests and waiting for clean up.

9. PACKING
Use a thick cardboard box, foam and carton protection corner to make transportation without problems.
