What are the differences between FFC connectors and FPC connectors and what are the common types?

Connector frequency of use is extremely high, in life, we more or less have seen the connector. For personnel, the connector is a daily need to contact the device. In order to enhance your knowledge of the degree of connector, this article will be from two aspects of the connector to explain: 1, a brief introduction to the connector, 2, the introduction of FFC connectors and FPC connectors and the difference between the two commonly used types.

First, a brief introduction to the connector connector, that is, CONNECTOR. domestic also known as connectors, plugs and sockets. Generally refers to electrical connectors. That is, the device that connects two active devices to transmit current or signal. Connector is a part of our electronic engineers and technicians often contact. Its role is very simple: in the circuit is blocked at the place or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment, along the current flow path observation, you will always find one or more connectors. Connector form and structure is ever-changing, with the application object, frequency, power, application environment, etc., there are a variety of different forms of connectors. For example, the connector used to light a lamp on a ball field is very different from the connector used to light a hard disk drive, or the connector used to light a rocket. However, regardless of the type of connector, it is necessary to ensure smooth, continuous, and reliable flow of current. In general terms, the connector is not limited to the current, in the rapid development of optoelectronics technology today, fiber-optic systems, the carrier of the signal is light, glass and plastic instead of ordinary circuits in the wire, but the optical signal path also use connectors, their role is the same as the circuit connector. Since we are only concerned with circuit connectors, this course will focus on circuit connectors and their applications in close conjunction with Molex products.

Second, the difference between FFC connectors and FPC connectors and commonly used types of today's connector form and structure is ever-changing, with the application object, frequency, power, application environment, there are a variety of different forms of connectors.FFC connector is a flexible flat cable connector, which is a kind of PET insulation and very thin tinned flat copper wire, through high-tech automated equipment production line press-fit It is a new type of data cable made of PET insulating material and extremely thin tinned flat copper wire, which is pressed together by high-tech automated equipment production line. It has the features of softness, folding and bending at will, thin thickness, small volume, simple connection, easy disassembly, and easy to solve electromagnetic shielding (EMI). The following is mainly about what is the difference between FFC connectors and FPC connectors, and FFC connectors are commonly used to the type of connector. 1.FFC connectors and FPC connectors FFC connectors are flexible flat cable connectors, FPC connectors are flexible printed circuit, from the two connectors above the manufacturing words, they line formation is different: a, FFC is used up and down FFC is the use of upper and lower insulating foils sandwiched between two layers of flat copper foil, the finished product is simpler, the thickness is thicker. b, FPC is the use of chemical etching of the FCCL (flexible copper-clad foil) processing to get the line away from the type of different single-sided and double-sided and multilayer structure of the flexible circuit board. In terms of price, naturally FFC connector is much cheaper, if you take into account the cost of production, more companies will like to use FFC connector related design.
