Introduction

Hello Everyone,
Warm greetings!
Today, we will discuss a 4-layer hybrid PCB that combines 8mil (0.203mm) RO4003C and FR-4, designed specifically for attenuator applications. This PCB has a thickness of 1.1 mm and features a blue solder mask with immersion silver plating on the pads, along with 1oz copper on each layer. Overall, it represents a straightforward multilayer PCB with a hybrid structure. These boards are manufactured according to IPC 6012 Class 2 standards using the provided Gerber data. Each board undergoes 100% electrical testing prior to delivery, with 25 boards packed for shipment.

Let’s look the stack-up:

The stack-up consists of layers from 1 to 2 made of the fixed thickness RO4003C core (8mil), which is crucial for maintaining the electrical length of RF lines on the circuit board. The remaining layers utilize FR-4 materials, and all boards feature through holes.
