Flexible PCB boards are divided into various types. These boards are differentiated on the basis of layers and properties.
FPCB has an extensive range of applications, “as long as there is display have FPC application.” Mobile phones, laptops, cameras, monitors, printers, cars, tablets, military, aerospace, medical, and so on are applied.
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.
The common rule for soldering on flex PCBs is this: Don’t use the temperature profile for conventional PCBs to solder flex PCBs.
The characteristics of flexible circuits are ideally suited for many applications that require high density interconnect between other components in a system.
Since flexible PCB has so many advantages, its price will naturally be higher than ordinary rigid 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.
Three elements of FPC are called flexible circuit board materials: Copper Foil, Adhesive, Polyimide & Polyester.
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.
FPC, short for Flexible Printed Circuit, is a highly reliable and excellent printed circuit board made of polyimide or polyester film as the base material.
JHY PCB is a leading PCB manufacturer in China, offers reliable, cheapest, and satisfactory PCB prototype services to customers.
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.
Five factors that FPC PCB designers should know about impedance control
