ENIG Multi Layer PCB,
1.88mm Multi Layer PCB,
1.88mm 3 Layer PCB Board
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)
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).
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.
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.
Features and benefits
1) Excellent high frequency performance due to low dielectric tolerance and loss;

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.
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.
