Flexible PCB

What Is Flexible PCB Coverlay (FPC Cover Layer)?

A flexible PCB coverlay provides the same functionality as a solder mask used on rigid PCBs. However, a flexible PCB coverlay offers more durability and flexibility which are very important in the application of flexible printed circuits compared to a solder mask with limited flexibility.

The Manufacturing Process Of Double-sided Flexible PCB Coverlay

One of the unique processes of the flexible printed board manufacturing process is the processing of the cover layer. The processing methods of the cover layer can be divided into three categories: cover film, screen printing, and photo coated layer.

Rigid PCB vs Flex PCB: What Is The Difference?

There are three classifications of PCBs namely Rigid, Flex, and Rigid-Flexible PCBs. This article provides a clear explanation of the fundamental difference between a Rigid PCB and a Flex PCB.

What Are Flexible PCB Stiffeners?

Flexible Printed Circuit Board stiffeners are applied to make certain parts of a flexible PCB rigid or stiff in order to make it easier for components to be soldered to the harder or stiffer part of the Board. Flexible PCB stiffeners are not part of a PCB’s electrical circuitry.

How to Solder On Flex PCB?

The common rule for soldering on flex PCBs is this: Don’t use the temperature profile for conventional PCBs to solder flex PCBs.

Flexible Printed Circuit For Today’s Packaging

The characteristics of flexible circuits are ideally suited for many applications that require high density interconnect between other components in a system.

Development and Applications of FPC Flexible PCB

With the upgrading of electronic products, FPC (flexible circuit board) caters to the development trend of light, thin, short, and small electronic products with its unique advantages and plays a critical cornerstone role in the electronic information industry.

Iphone12: Mass application of flexible circuit board

FPC: Many smartphones and smart hardware applications have brought more and more market space for FPC. PI cover film FPC is the most common type of flexible circuit board, further subdivided into single-sided FPC, double-sided FPC, multilayer FPC, and rigid-flex PCB board.

Knowledge of Plating on Flexible Circuit Board Surface

Electroplating is a vital link in the PCB manufacturing process. The electroplating process of flexible PCB needs to pay attention to the following points: pretreatment of FPC electroplating, electroplating thickness, stain treatment after electroplating, etc.
