Assembly Service

Providing OEM service to all sorts of Printed Circuit Board Assembly

Our service projects:

1. Board production
With a monthly production capacity of 27,000 square meters, it can be used as a 2-64 layer high precision circuit board; it serves long-term foreign well-known enterprises.
2. PCBA OEM replacement
Professional one-stop circuit board OEM, more than ten years of work experience, find us, you have your own processing plant!
3. Purchase components
We have long-term cooperation with component suppliers. These components are original and brand new. 100% quality guaranteed.
4. PCB copy board
Based on the reverse development of the prototype, it provides learning and research materials for engineers and R&D institutions.

Quality control:
The whole process of IPQC (in-process quality control) detection is one of our highlights. In the process flow of 20 or 30 PCB boards, setting the key point IPQC can avoid the opportunity cost of the subsequent process caused by the error, facilitate early detection and improvement, effectively reduce the scrap rate and reduce the production cost. The benefits are passed on to the customer, creating lasting value for the customer. In addition, standard flying probe testing, test bench testing, AOI (automatic optical inspection) and other visual inspections form a closed loop combination of the quality inspection procedures routinely performed in our circuit board factory.
