Metal Core PCB
Metal core PCB is thermal management circuit board used in LED lighting which needs fast cooling
dissipation. The metal core can be aluminum (aluminum core PCB) and copper (copper core PCB),
stainless steel, even iron base.
Advantages of MCPCB
1) Effective heat dissipation reduces the operating temperature of the module and prolongs the
service life;
2) Power density and reliability are improved up 10%;
3) Reduce the dependence of heat sinks and other hardware (including thermal interface materials);
4) Reduce the volume of the product;
5) Reduce the cost of hardware and assembly;
6) Optimization combination of power circuit and control circuit;
7) Replace the fragile ceramic substrate and obtain a better mechanical durability;
8) Reduce the operating temperature of the equipment.
Applications
LED lighting, Switch regulator, DC/AC converter, Communication electronic equipment, A filter
electric circuit, Office automation equipment, Motor driver, Motor controller, Automobile etc.
Solder Mask
Depending on whether light is to be absorbed or reflected, we have green, black and white solder
mask. White solder mask is commonly used in LED PCB application and we use super white LED
solder mask and no yellowish or brown colour occurs after the bare PCB baking as well as reflow
and wave solder PCB assembly processes.

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.
