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

3 Layer High Frequency PCB Built On 60mil RO4350B and 6.6mil RO4350B with ENIG for Wireless Booster

(PCB’s are custom-made products, the picture and parameters shown are just for reference)

 

Hi Everyone,

Multilayer high frequency PCBs are made from all high frequency material inclusive of prepreg adhesive. For example, a 4-layer RO4350B PCB is a compound of 2 cores of RO4350B substrates. As is known to all, there’re 8 cores in RO4350B family, i.e. 4mil (0.101mm) to 60mil (1.524mm).

RO4350B:  
4mil 0.101mm
6.6mil 0.168mm
10mil 0.254mm
13.3mil 0.338mm
16.6mil 0.422mm
20mil 0.508mm
30mil 0.762mm
60mil 1.524mm

So it’s very interesting that stack-up of 4 layers can be done in many different ways.

 

This 3-Layer high frequency PCB is built on 2 cores of RO4350B and one layer of copper is etched off, left 3 layers on.

3 Layer High Frequency PCB Built On 60mil RO4350B and 6.6mil RO4350B with ENIG for Wireless Booster

The structure is one sheet of 60mil RO4350B plus 4mil RO4450F prepreg and combined 6.6mil RO4350B. The board is a square with 110mm x 110mm, with immersion gold finishes on pads. They’re 20 pieces packed for shipment and used for wireless booster.

Following is the actual value in engineering manufacture.

Our 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.
