PCB Case: 6 Layer PCB Built on RO4003C (20mil) +
RO4450F Bondply With Immersion Gold
(Printed circuit boards are custom-made products, the picture and parameters shown are just
For reference)
General description
This is a type of 6 layer high frequency PCB built on 20mil RO4003C with bondply RO4450F
For the application of radar altimeter. High frequency multilayer PCB has different stackup from
Epoxy PCB (FR-4). For this 6 layer PCB, it uses 3 core of RO4003C for its construction. The
Prepreg that matches is RO4450F, instead of the usual PP used in FR-4 PCB.

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.
Control of Production Process
Right manufacturing instruction (MI), comprehensive equipment management and maintenance
And process control, strict WIP inspection and monitoring as well as working instruction, all those
Make the whole fabrication process totally controlled.
Final Control and Inspection
All PCBs have to be gone through the open and short test as well as visual inspection after
Passed the specified physical tests. We own various advanced test equipment including
Customized, probe flying test machines to guarantee that each PCB is 100% tested.
Product Delivery Audit
We set up a dedicated FQA department to inspect the PCB products according to the customer's
Specifications and requirements by sampling. Qualified PCBs are going to be packed.
FQA also has to carry out a 100% audit of the warehouse packing and shipping products, including
Product number, customer number, product quantity, shipping address and so on prior to shipment.
Customer Service
We sets up a professional customer service team to proactively communicate with customers and
Timely deal with the customers' feedbacks. We highly focus on customers' needs and to understand
Customers' demands, timely to adjust the policy of customer service and PCB product
Requirements.
