Introduction

Just as its name implies, high frequency is that the frequency is relatively high, generally refers to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band. The electromagnetic wave of frequency >=1GHz is called microwave.

 

High frequency printed circuit board or microwave PCB refers to the printed circuit board made on the high frequency (microwave) substrate copper clad plate. The common types are: Double-sided board, multilayer board and mixed structure.


Mixed structure includes high performance special substrate, PP sheet + ordinary performance board and PP sheet mixed pressing board; high frequency substrate + ordinary FR4 substrate; high frequency substrate + metal base etc.

 

Advantages
1) The characteristic of low dielectric loss makes the signal loss at a lower level, which makes the signal transmission of the whole equipment excellent;
2) Low water absorbability influences dielectric constant and dielectric loss less at damp;
3) The temperature coefficient of dielectric constant is among the lowest of any circuit board material, making it ideal for temperature sensitive applications;
4) Stable electrical coefficient of dielectric constant;
5) Superior corrosion resistance;
6) The dielectric constant (DK) is low and stable, so the signal transmission is good without delay;

 

Typical frequencies for wireless applications:
* Current mobile: 0.9GHz - 2GHz
* 3G systems: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz

Brief Introduction
With the development of electronic communication technology, the communication frequency is becoming higher and higher, and the high frequency signal transmission, need to use low dielectric constant (Dk), low dielectric loss (Df) but expensive special materials. These materials have cyanate and high frequency materials such as polytetrafluoroethylene / ceramic based materials (PTFE/Ceramic), hydrocarbons / ceramic based materials (Hydra Carbon/Ceramic). Usually these materials are expensive.
Reducing the cost is an important means for customers to improve the competitiveness of products. Therefore, the customers adopt the laminated structure of mixed materials in the design of PCB structure, that is, the necessary signal layer uses high-frequency materials to meet the needs of signal transmission. Other line layers are made of conventional fiberglass epoxy FR-4, which we call a hybrid board.

PCB Case: Hybrid PCB Mixed Material PWB Built On 10 mil RO4350B+FR4 With Blind Via
(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)
 
General description
This is a type of hybrid PCB built on RO4350B and FR-4 with 6 layer stackup for the application of radar antenna. On the other hand, it's not just 6 layer board which is directly designed from client. The designer wants a double sided RO4350B circuit board combined with a 4 layer circuit board.The 2 types PCB has it's own drill, so the final PCB becomes a 6 layer PCB with blind via. Afer prcoess of press,it leaves 1.8 mm thick. White silkscreen over green solder mask is printed on board and immersion gold are plated on pads. The base material is used from ITEQ IT-158 and Rogers 10mil RO4350B, entire board supplying single up per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.

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.
