Flexible Printed Circuit Board-Flex PCB

Flexible printed circuits actually utilize flexible laminates. The raw materials and properties of the laminate are important not only for its manufacturing process, but also for the performance of the finished circuit. Flex PCB manufacturers consist of a conductive foil and a dielectric substrate.

There are two types of dielectrics used in flexible printed circuits.

1. A) Thermoplastics: Materials that soften by heat input after curing, such as polymers, polyesters, and fluorinated hydrocarbons.
2. B) Thermosetting plastic: Material such as polyimide and polyacrylate.

Here, let’s make sure that almost all flexible PCBs are built on polyimide or polyester film, while copper material, copper as a conductor, is commonly used and offered in the form of foil. .. Aramid and fluorocarbon films are also used for some special purposes.

The choice of a particular film selection depends on several factors. These are:

-Cost-reduced or inexpensive flex circuits provide performance at low cost, but are built on polyester film with reduced thermal resistance.

-Ultra-high performance flex PCBs, especially those for military applications, are made of polyimide film due to their best overall performance.

-Aramid non-woven fiber material is not expensive and has excellent mechanical and electrical properties, but the problem is that this material absorbs moisture.

-Fluorocarbons are an expensive material and very difficult to handle, but they offer the best dielectric properties. This material is mainly used for control impedance applications.

For applications, a common material choice for flexible circuits is polyimide film. This is due to the average performance and cost factors of chemical properties, electrical and thermal performance. This material can withstand the temperature of manufacturing soldering operations. This material is also used to insulate wires and motors and transformers.
