Product Description

General description
This is a type of high frequency PCB built on 60mil (1.524mm) RO4350B substrate with Tg 280°C
for the application of radar systems. It's double sided board at 1.6 mm thick, black silkscreen directly
on TF substrate and immersion gold is on pad for soldering. The base material is from Rogers
Corp, entire board supplying 1 PCBs per panel. They're fabricated per IPC 6012 Class 2 using
supplied Gerber data. Each 25 panels are packed for shipment. 

Features and benefits    
Low water absorbability influences dielectric constant and dielectric loss less at damp;
Heat resistance, chemical resistance, impact strength and peeling strength are good;
The temperature coefficient of dielectric constant is among the lowest of any circuit board
material, making it ideal for temperature sensitive applications;
Excellent surface planarity, helpful for PCBs with BGA packages to reduce failure rate during
assembly and soldering;
SMT process is resistant to reflow soldering, resistant to rework;
Reliability test, insulation resistance test and ionic contamination test;
Meeting your PCB needs from prototype to mass production;
Quick Lead time: 3-5 days;
Small quantity order is accepted;
Free-of-charge PCB prototype test;
IPC Class 2 / IPC Class 3;


Application
RF transceiver, Variocoupler, Frequency converter,  RF transceiver

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.
