The questions often crops as to what is customizeflex PCB and how it goes on to enhance product design. It is a flexible printed circuit board and is referred to as a flexible printed circuit and it has different properties than a rigid circuit board. Hence it is suitable to be used for different applications. Credit is due to the miniaturized design as package weight drops by 75 %.

With each passing year, the demand for powerful technology is on the rise. Consumers in all industries throng for quality performance, with size restrictions and smaller weight. This poses a major issue on how larger electronics can be formulated in small packages. Due to this scenario, the flexible printed circuit board emerged and over time the applications have grown.

The various forms of flex PCB

Over the course of time flex, PCB has become complex and it is applicable to a variety of industries across the board. Below are some of the common types of printed circuit boards that are being used below

  • Single-sided flexible circuits– it happens to be one of the common forms of PCB flex that is available in the market. There is a single conductor layer and only on one side, it is printed. Since it is easy to produce this customizable rigid-flex PCB is readily available in the market. Due to their low weight and simplicity, the printed circuit is part of most calculators.
  • Double-sided flexible circuits– Printing occurs on both sides and is plated through holes. It is popular for its circuit density and power handling capabilities. The main reason why it is popular is due to the increase in power. In fact, it is expensive to produce in comparison to a single-side flexible circuit.
  • Multi-layer flexible circuits– there are flexible circuits that consist of three or more layers of conductors. Due to the complex nature of its construction, it tends to be costly to produce in comparison to its counterparts. Their main use is in military applications and aerospace which justifies capabilities and cost to a considerable extent.

A flexible printed circuit board has numerous benefits in comparison to a rigid PCB. For this reason, it is commonly used in consumer electronics but it does have its own set of drawbacks. Hence rigid and flexible PCBs do not have their own uses and mostly they are used in conjunction with rigid flex circuits.
