The difference between FFC connector and FPC connector and what are the common types

 The frequency of use of connectors is extremely high. In life, we have seen connectors more or less. For professionals, the connector is a device that needs to be touched every day. In order to improve everyone's understanding of connectors, this article will explain the connectors from two aspects: 1. A brief introduction to the connectors, 2. The difference between FFC connectors and FPC connectors, and the common types of the two .

1. A brief introduction to the connector
The connector refers to an electrical connector. That is, a device that connects two active devices to transmit current or signal.
The connector is a component that our electronic engineering and technical personnel often contact. Its function is very simple: it builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. Connectors are an indispensable part of electronic equipment. Observing along the path of current flow, you will always find one or more connectors. Connector forms and structures are ever-changing. There are various types of connectors with different application objects, frequencies, power, and application environments. For example, the connectors for lighting on the court are very different from the connectors for hard drives, and the connectors for lighting rockets. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly, continuously and reliably. Generally speaking, what the connector is connected to is not limited to current. In today's rapid development of optoelectronics technology, the carrier of the signal transmission is light in the optical fiber system. Glass and plastic replace the wires in the ordinary circuit, but the optical signal Connectors are also used in the pathways, and their functions are the same as circuit connectors. Since we only care about circuit connectors, this course will closely integrate Konnra's products, focusing on circuit connectors and their applications.
FPC connectors
2, The difference and common types of FFC connectors and FPC connectors
Today's connector forms and structures are ever-changing, and there are various types of connectors with different application objects, frequencies, power, and application environments. The FFC connector is a flexible flat cable connector. It is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, which is laminated through the production line of high-tech automation equipment. It has soft, flexible bending and folding. , Thin thickness, small size, simple connection, convenient disassembly, easy to solve electromagnetic shielding (EMI). The following mainly talks about the difference between FFC connector and FPC connector, and the commonly used types of FFC connector.
1. The difference between FFC connector and FPC connector
The FFC connector is a flexible flat cable connector, and the FPC connector is a flexible printed circuit. From the manufacturing of the two types of connectors, the way they are formed is different:
a. FFC is a flat copper foil sandwiched between upper and lower insulating foil films. The finished product is simpler and thicker.
b. FPC is to process FCCL (flexible copper clad foil) by chemical etching to obtain flexible circuit boards with different single-sided double-sided and multilayer structures.

In terms of price, naturally FFC connectors are much cheaper. If production costs are taken into consideration, more companies will like to use FFC connector related designs.

FFC cable

2. 7 common types of FFC connectors
Type A: Both ends are connected and the reinforcing plate is pasted on the insulating tape;
Type B: Cross the reinforcing plate and paste it directly on the insulating tape;
Type C: The reinforcing plates at both ends are directly pasted on the conductor;
Type D: Cross the reinforcing plates at both ends and paste directly on the conductor;
Type E: One end of the reinforcing plate is attached to the insulating tape, and the other end is directly soldered;
Type F: The reinforcing plates at both ends are directly attached to the insulating tape, and the inner half is peeled off;
Type G: Direct soldering at both ends.
FFC cables

Generally speaking, the development of today's FFC connector technology has the following characteristics: high-speed and digital signal transmission, integration of various signal transmissions, miniaturization and miniaturization of product volume, low-cost products, contact termination The way is surface-mounted, modular combination, convenient plug-in and so on.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and

Talking about the function, classification and working principle of OTG data line

  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mobile devices wi

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con
