KKPCB Case Study: Hybrid Power+RF PCB for Base Station Applications

KKPCB Case Study: Hybrid Power+RF PCB for Base Station Applications

Client: Anonymous
Industry: Telecom Infrastructure, 5G Macro/Micro Base Stations
Application: Power Amplifier (PA) Modules + RF Front-End PCBs

High-power base station equipment requiring PCBs are able to handle:

High current (30A+) for PAs

Low-loss RF (3.5GHz-28GHz for 5G)

Thermal stability (85°C ambient, 125°C local hotspots)

Key Challenges Faced:

Delamination risk from mixed thick-copper (6oz) and RF layers.

EMI coupling between power and RF sections.

Thermal warping under high thermal cycling.

KKPCB Case Study: High-Frequency Fiber Optic Transceiver PCB for Fiber Instrument Sales

Client:  Anonymous
Industry: Fiber Optic Test & Measurement, High-Speed Data Transmission
Application: Next-gen 100G/400G+ optical transceivers, OTDR equipment, and 50GHz RF test modules.

FIS designs precision fiber optic tools, requiring ultra-low-loss PCBs to maintain signal integrity at millimeter-wave frequencies (up to 50GHz). Their challenges include:

Insertion loss degrading high-speed signals (>40Gbps).

Impedance mismatches causing reflection noise.

Thermal expansion leading to microvia cracking in compact designs.

KKPCB Case Study: High-Performance Communication Backplane PCB Solution

The customer is a globally leading manufacturer of communication equipment, specializing in the development and production of large-scale routers, switches, servers, and high-speed networking devices. As modern network communications demand increasingly high signal integrity, reliability, and thermal stability, the customer required an 18-layer PCB with low-loss material (S1000-2M) and advanced immersion gold plating to ensure stable signal transmission and long-term reliability

Multilayer PCBs

Multilayer PCB Manufacturing Process, Advantages and Applications

A Multilayer PCB (Printed Circuit Board) is a type of PCB with more than two conductive layers. Unlike a double-sided PCB, which has two copper layers (top and bottom), a multilayer PCB consists of three or more layers of copper, interconnected by copper-plated vias. The number of layers can range from 3 layers to 40 layers or more, depending on the design requirements

Rigid-Flex PCB

Rigid-Flex PCB – Types of PCBs

Rigid-Flex PCB is a hybrid of both rigid and flexible PCBs. In its simplest form, Rigid-Flex PCB consists of a rigid circuit board joined with a flexible circuit board, combining the advantages of both types.

A Rigid-Flex PCB is made by laminating a rigid and a flexible substrate together to form a single board. Double-sided or multi-layer Rigid-Flex PCBs are interconnected by Plated Through Holes (PTH).
