Differences & Common Types of FFC Connectors & FPC Connectors

Today's connector forms and structures are ever-changing. There are various types of connectors depending on the application object, frequency, power, and application environment. The FFC connector is a flexible flat cable connector. It is a new type of data cable that is pressed together with a high-tech automated equipment line using PET insulation and extremely thin tinned flat copper wire. It has a soft, freely bendable fold. The utility model has the advantages of thin thickness, small volume, simple connection, convenient disassembly and easy resolution of electromagnetic shielding (EMI). The following mainly talks about the difference between FFC connectors and FPC connectors, and the types commonly used by FFC connectors.

The difference between FFC connector and FPC connector

FFC connectors are flexible flat cable connectors, and FPC connectors are flexible printed circuits. The way they are formed is different in terms of the manufacture of their two connectors:

1. FFC is a flat copper foil sandwiched between two upper and lower insulation foil films. The finished product is simpler and thicker.

2. FPC is a chemical circuit that treats FCCL (Flexible Copper Clad) to obtain flexible circuit boards with different single-sided double-sided and multi-layer structures.

In terms of price, natural FFC connectors are much cheaper, and if you consider production costs, more companies will like to use the relevant design of FFC connectors.

FFC connector 7 common types

Type A: the two ends are connected and the reinforcing plate is attached to the insulating tape;

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

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

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

Type E: One end reinforcing plate is attached to the insulating adhesive paper, and the other end is directly soldered;

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

Type G: Direct soldering at both ends.

In general, the development of today's FFC connector technology has the following characteristics: high speed and digitization of signal transmission, integration of various signal transmissions, and miniaturization of product volume, cost reduction of products, termination of contacts, Ways of surface labeling, module combination, convenience of plugging and unplugging, etc.
