The advantages of Bicheng Company
Cutting-edge technology: it is rational for a small and medium-sized customer to hanker after the
latest equipment and manufacturing expertise for its PCBs. By the partnerships with Bicheng PCB,
you gain access to reach your expectation with our 3 factory bases with over 26,000 square
meters.
Frequently Asked Questions
1. What's your minimum isolation of layers?
The minimum thickness of prepreg in inner layer is 0.06mm for prototypes, and thicker at 0.1mm
for mass production.
2. Do you have any preferential policies for a new customer?
Yes. New customers can enjoy the first prototype order free shipping policy in Bicheng. That's to
say you do not need to pay for the shipping cost for your first protoytype order.
Quality Policy
Bicheng has developed series of management procedures and approaches to assure that PCBs
are in compliance with the customers' requirements, inclusive of selection of the vendors, work
in progress (WIP) inspection, outgoing delivery inspection and customer service etc.
Evaluation and Audit of Suppliers
Suppliers have to be evaluated by Bicheng. In addition, Bicheng will appraise and rank suppliers
every year to guarantee the materials supplied are meeting Bicheng's requirements. Furthermore,
Bicheng continuously develop suppliers and supervise them to improve their quality and
environment management basing on the systems of ISO9001 & ISO14001.
Contract Evaluation
Bicheng shall review and verify customer's requirements to make sure that we have the capability
to satisfy customers' requirements including specifications, delivery and other demands prior to
accepting an order.
Making, audit and control of manufacturing data.
When customers' design data and specifications are provided to our market department, Bicheng
has to verify all the requirements. Then, convert the design data into manufacturing data by CAM.
Finally, a manufacturing instruction (MI) is generated according to the real manufacturing process
and technologies for manufacturing department as the basis for actual fabrication. MI must be
reviewed by independent engineers and QA engineers before issue.
Incoming Material Quality Control
All materials have to be inspected before warehousing. We established a series of strict inspection
procedure and instruction to control the incoming materials. Furthermore, various precise
inspecting instruments and apparatus guarantee the capability to judge the material good or not.
We issue material with first in first out principle, and give out "alarm" for the material that will reach
the shelf life to ensure the materials are used up before expiry.
