Quality Control

3A Prototype invests a huge amount of money to inspection equipment and inspectors training. We have set up a quality control system and ensure every part is inspected and approved to release by inspection department prior to shipment. The basic goal of our quality control is to ensure our products and service can meet specific requirements from customers and ensure our production can be dependable, satisfactory and consistent.

How Does 3A Prototype Do the Quality Control?

We will do the FA inspection and rolling inspection, for high volume production, we do CPK analysis.

Detail Inspection include:

Dimension Inspection:

Parts critical dimensions will be checked according to 2D or customers special tolerance or our standard ISO2768 tolerance
