With over 20 years of experience in handling different kinds of PCBs, our state-of-the-art equipment and team of experts provide significant advantages.

2.How long does it take for you to provide hybrid PCB lead time?

We have over 20 years of experience in the PCBA industry and we pride ourselves on providing our customers with a fast turnaround cycle, you can contact us if you have mixed PCB needs.

3.Do you provide multi-layer hybrid PCB?

Yes, we can provide multi-layer hybrid PCB with 2-64 layers.

4.When should a hybrid PCB be used?

Whenever you want to expand your creativity for desired electrical, thermal and mechanical properties, you can use hybrid PCBs. There are many other aspects you should consider before using a hybrid PCB; including the desired application, temperature, frequency type, cost, and more.

5.What kind of materials are used in hybrid PCBs?

Hybrid PCBs use materials with different key properties than traditional multilayer PCBs. Often a mixture of FR-4 material with high frequency PTFE material, or a mixture of different high frequency materials with different dielectric constants is used.

6.What is a hybrid PCB?

Hybrid printed circuit boards are PCBs that use different materials to optimize electrical performance and improve system reliability.

7.What finishes do you offer for high frequency PCBs?

We offer ROHS-Immersion Tin, Gold, Silver finish. Also, if you need any custom finishing of high frequency bare boards, please feel free to contact us.

8.What is the thickness of the high frequency PCB?

We can supply board thicknesses from 0.4mm to 5mm. Although, we can also provide custom high frequency printed circuit boards.

9.What are the different materials you usually use for high frequency PCBs?

We use a range of materials including RO4350B, RO3003, RO4003C, RO3010, RT5880

10.What is a high frequency PCB?

A high-frequency PCB is a type of PCB that is ideal for high-speed design applications that typically require a frequency range of 500MHz to 2GHz.

11.What types of rigid-flex PCBs are there?

Rigid-flex printed circuit boards are mainly divided into three types, including single-sided rigid-flex PCB, double-sided rigid-flex PCB, and multi-layer rigid-flex PCB.

12.What are the steps in the rigid-flex PCB manufacturing process?

The rigid-flex PCB manufacturing process involves multiple steps including substrate preparation, circuit pattern generation, overlays, cutting flex, electrical testing, and verification.
