Today's connector forms and structures are ever-changing. With the application object, frequency, power, application environment, etc., there are various forms of connectors. FFC connector is a flexible flat cable connector. It is a new type of data cable that is made of PET insulating material and extremely thin tinned flat copper wire through high-tech automation equipment production line. It has soft, random bending and folding. , Thin thickness, small size, simple connection, convenient disassembly, easy to solve the electromagnetic shielding (EMI).

The following mainly talks about the difference between FFC connectors and FPC connectors, and the types commonly used in FFC connectors.

The FFC connector is a flexible flat cable connector, and the FPC connector is a flexible printed circuit. In terms of the manufacture of their two connectors, the way their lines are formed is different:

1. FFC is a flat copper foil sandwiched between the upper and lower layers of insulating foils. The finished product is simpler and thicker.

2. FPC is to process FCCL (flexible copper clad foil) by chemical etching to obtain flexible circuit boards with different circuit patterns, single-sided, double-sided and multi-layer structures.

In terms of price, the natural HOUSING WAFER CONNECTOR is much cheaper, and if the production cost is considered, more companies will like to use the related design of the FFC connector.

Seven common ffc connector types

Type A ffc connector : Both ends are connected and the reinforcing plate is pasted on the insulating tape;

Type B ffc connector : The reinforcing plate is directly pasted on the insulating tape;

Type C ffc connector : The reinforcing plates at both ends are directly pasted on the conductor;

Type D ffc connector : The reinforcing plates at both ends are directly pasted on the conductor;

Type E ffc connector : One end of the reinforcing plate is attached to the insulating tape, and the other end is directly soldered;

Type F ffc connector : The reinforcing plates at both ends are directly attached to the insulating tape, and the inner half is peeled off;

Type G ffc connector : Direct soldering on both ends.

In general, the development of today's low profile FFC connector technology has the following characteristics: high-speed and digital signal transmission, integration of various types of signal transmission, miniaturization of product volume, low cost of products, contact termination The met

od is surface-mounted, module combination, convenient plugging and unplugging, etc.
