Why Can We Always Ensure Excellent Quality

Quality Control

Quality is the most important points of our products.

Here are steps of producing and methods to ensure high quality

Step 1: Qulity checking for incoming materials

Step 2: Assembling mechanical parts

Step 3: Solder inner electrical componnets

Step 4: Test circuit and resolution, especially for waveform and power supply voltage

Step 5: Appearance checking

Step 6: Final inspection before shipping out
