Introduction

Rogers prepreg has revolutionized the electronics manufacturing industry with its unique properties that enable advanced circuitry and reliable performance. As electronics continue to advance, Rogers prepreg remains at the forefront of innovation.

What is Rogers Prepreg?

Rogers prepreg is a composite material that consists of reinforcement fibers like glass or ceramic impregnated with a thermoset resin. The resin fully saturates and coats the fibers before the material is semi-cured into broad rolls of tacky sheets.

The pre-impregnated composite can then be laid up and laminated into a finished circuit board. The prepreg allows the resin to flow and adhere the layers together when heat and pressure are applied.

Key Properties

• Excellent dielectric performance
• Tight thickness tolerance
• Low loss for high frequencies
• Consistent material properties
• Designed for automated circuit board assembly

Rogers prepreg stands out for its exceptional dielectric properties and low signal loss. It maintains these electrical properties consistently across production runs.

Applications of Rogers Prepreg

Rogers prepreg enables the construction of advanced circuit boards for:

• Wireless communication – 5G networks, radar, automotive sensors
• High speed digital – data centers, network infrastructure, telecom
• Aerospace and defense – radars, guidance systems, avionics
• Automotive – ADAS, powertrain, infotainment
• Medical** – imaging, diagnostics, surgical tools

The consistent and reliable performance of Rogers prepreg allows circuit designers to push the envelope for the latest electronic applications.

Rogers Prepreg Circuit Board Manufacturing Process

Constructing a circuit board using Rogers prepreg involves:

Step 1: Laminate Stackup

The prepreg sheets are layered up with other materials like copper foil and composite cores. This creates the laminate stackup.

Step 2: Alignment and Tack

The stackup layers are aligned and tacked together to hold the prepreg in place.

Step 3: Autoclave Pressing

The tacked stackup goes into an autoclave for high temperature and pressure pressing. This flows the resin to bond the layers together.

Step 4: Photolithography

The pressed circuit board panel goes through photolithography patterning to form the circuit traces.

Step 5: Add Components

Components are soldered onto the board to create the final functional printed circuit board.
