Flexible PCB Manufacturing-Hitech Circuits

Description

What is a flexible PCB board?

Flexible PCB circuit board, also called soft board, FPC board, is a kind of pcb, with excellent flexibility. FPC circuit board can complete the overall wiring work on one machine, which can be expanded and moved arbitrarily according to the space layout requirements, reduces the wiring volume, realizes the integration of component assembly and wire connection, and promotes electronic products to be smaller, lighter and thiner.

FPC flexible circuit board is made of polyester film or polyester imide, which is light and thin, high density, high flexibility, bendable and foldable, and has advantages that other types of circuit boards do not have. Compared with traditional interconnection technology, FPC flexible circuit boards can withstand millions of bending times, are easy to install, and have good heat dissipation, which are favored by the market.

Advantages of flexible PCB boards
Flexible PCB boards are printed circuits made of flexible insulating substrates, and have many advantages that rigid PCB boards do not have:

1. It can be bent, wound, and folded freely, can be arbitrarily arranged according to the space layout requirements, and can be moved and expanded in three-dimensional space, so as to achieve the integration of component assembly and wire connection;

2. The use of FPC board can greatly reduce the volume and weight of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields or products;

3. Flexible pcb board also has the advantages of good heat dissipation and solderability, easy assembly and low overall cost, etc. The design of Rigid-flex PCB also makes up for the slight deficiency of the flexible substrate in the component carrying capacity to a certain extent.

Disadvantages of flexible PCB boards
1. High one-time initial cost: Since the flexible PCB is designed and manufactured for special applications, the initial circuit design, wiring and photographic masters require higher costs. Unless there is a special need to apply a flexible PCB, it is usually better not to use it in a small amount of application;

2. It is difficult to change and repair the flexible PCB: once the flexible PCB is made, it must be changed from the base map or the programmed light drawing program, so it is not easy to change. The surface is covered with a protective film, which must be removed before repair and restored after repair, which is a relatively difficult task;

3. Size is restricted: Flexible PCBs are usually manufactured by batch method when it is not yet common. Therefore, due to the size of production equipment, they cannot be made very long and wide;

4. Improper operation may easily cause damage: Improper operation by the installation and connection personnel can easily cause damage to the flexible circuit, and its soldering and rework need to be operated by trained personnel.
