The PCB assembly industry uses multiple PCB categories, and all categories have different types that are differentiated by the qualities like materials used. So, if you are stuck in the PCB assembly phase and want to choose the right materials for your rigid-flex PCB, then this guide is for you.

Why choosing the right material for your Rigid-Flex PCB is important in the PCB assembly industry?

Today there are many materials we can use for manufacturing our PCBs. These materials differ in the following qualities:

  • Ability to deal with harsh conditions
  • Ability to maintain performance
  • The overall cost of the PCB
  • Ability to work under extreme temperature

Since every application of this PCB differs, choosing the wrong material can significantly impact the above-listed factors. That's why choosing the right materials is extremely important.

How to Choose the Right Materials for Your Rigid-Flex PCB?

Here is everything you need to know about the different factors when choosing the materials for your PCB.

  1. Selecting the conductor

The conductor is among the most important materials in a PCB since it transfers the signals. So, you should start with the conductor and ensure you pick the right material. Copper is a good choice since it meets all the requirements while keeping things cheap.

  1. Selecting the dielectric

Dielectric creates insulation between multiple conductor layers, and polyimide is a good material for this use case. It is commonly used for specific use cases since it is cheap yet ensures high performance from your PCBs, even under harsh conditions.

  1. Selecting the cladding material

Polyester is a good cladding material because it only covers the dielectric and protects it. Polyester is flexible and moisture-resistant, making it good for rigid-flex PCBs.

Other factors to look for when choosing materials for the Rigid-Flex PCB

Since you know about the factors that get affected by choosing the right materials, here are more details about why you need to care for those factors.
  1. The application of that PCB

When selecting the material, you need to check the application of the PCB. For example, you may need a material that easily deals with harsh conditions while selecting a low-quality one. That will make your PCB inefficient for the use case.

  1. Performance requirements

Secondly, check the performance requirements when selecting the material. Not all materials perform well at transferring signals under different conditions. Signal attenuation is important for performance integrity, so choose materials that offer the signal attenuation you need.

  1. Pricing

Pricing is also an important factor for many, especially on a budget. Getting the best materials when you don’t need them will increase the cost, and you may get out of budget.
