Total quality management

We take an all-inclusive approach, from qualified managed suppliers to packaging and delivery, to ensure that products could meet the highest standards of our customers. We always start with customer needs and end with customer satisfaction.

Quality requirements of the whole process

High quality assurance comes from our high attention to every process, from procurement, reception, inspection, testing to transportation.

Quality awareness of all staff

Through the promotion of quality policy and quality system training, HJC continuously improves the team's anti-counterfeiting ability and network security awareness to meet customer requirements and their future needs and expectations.

Authoritative quality certification

HJC is dedicated to exceed customer requirements and expectations, adhere to third-party certification requirements, while constantly improving our quality management system, so as to provide customers with the highest level of products and services.

Inspection tools & Inspection equipment

HJC has purchased in a series of inspection equipment and tools to support our quality inspectors to identify the most subtle defects and complex counterfeit parts in advance.

X-RAY

X-RAY, generated by high voltage impingement on the target material, could penetrate most objects. Our inspection engineers, taking use of the feature, use X-ray penetration imaging without damaging the test sample, can clearly observe the internal structure of the chip and the solder quality of the various types of SMT joints,thus verify whether there are problems with the components and eliminating the use of inferior and counterfeit components.
Solderability test equipment

The solderability of components, PCB boards, PADS, solders and fluxes are evaluated qualitatively and quantitatively by the principle of wet-balance method.
D-CAP

The weldability of components, PCB boards, PADS, solders and fluxes are evaluated qualitatively and quantitatively by the principle of wet-balance method.
Visually inspect the equipment

The appearance of the chip is inspected to determine whether there are abnormal phenomena such as cracks and damage.
