0.15mm Flexible Circuit with FR4 Stiffner Yellow Coverlay Immersion Gold

The newly shipped Flexible Circuit Board (PCB) brings a groundbreaking advancement to the world of circuitry. Designed to offer unparalleled flexibility, this state-of-the-art PCB, also known as a flex circuit or flexible printed circuit board, is crafted from cutting-edge materials such as polyimide or polyester. Unlike traditional rigid PCBs, it possesses the remarkable ability to bend, twist, and conform to fit any desired shape or space requirements, revolutionizing the possibilities of circuit design.

The essence of this flexible circuit lies in its three fundamental elements: copper foil, dielectric material, and adhesive. These components work in synergy to provide exceptional performance and durability, making the PCB an indispensable solution for a wide range of applications.

The primary purpose of the Flexible Circuit Board is to establish reliable interconnections between printed circuit boards and other components. It serves as a three-dimensional substrate for mounting surface-mount technology (SMT) components, making it ideal for photographic and video cameras and other devices that require intricate assembly. Furthermore, these circuits are capable of withstanding dynamic flexing, ensuring consistent performance even in demanding environments. Additionally, they seamlessly integrate into flex/rigid circuit boards, further expanding their versatility.

There are four basic types of flexible circuits, each tailored to specific requirements:

1. Single-Sided Flexible Circuits: With a thin and flexible base material, a copper foil is laminated using adhesive. The finished circuit often features a covercoat bonded to the copper side, providing enhanced protection and insulation.

2. Double-Sided Flexible Circuits: This type consists of a thin and flexible base material with copper foil laminated to both sides. The outer sides of the circuit are frequently equipped with covercoats, further fortifying the copper layers.

3. Multilayer Flexible Circuits: Comprising multiple thin and flexible base laminates and copper foils, these circuits are laminated together using adhesive. Similar to rigid multilayer boards, covercoats are commonly added to the outer sides for added durability.

4. Flexible Circuits with Rigid Areas: In scenarios where the flexible circuit must support heavy components or connectors, reinforcement becomes necessary. This is achieved by bonding a stiffener, such as an extra layer of polyimide or a glass/epoxy laminate, to the designated area.

This Flexible Circuit Board is constructed using Shengyi's SF201 series Polyimide materials.
