According to the current connector market to see the board-to-board connectors are increasingly widely used background and driving force from the wireless device market two major trends: the size will be smaller, the price will be lower. As seen in the wireless terminal market, smaller, lighter and cheaper is also the trend in the wireless device market. The reduction in device size means that it saves space, reduces weight and leaves more excess for the rest of the system design. The decreasing size of devices requires higher integration and smaller size of all devices in the device, including RF coaxial connectors and their cable assemblies that are widely used in RF modules and interconnections between them. The RRH (remote radio head), which is widely used in distributed base station systems, must be designed to be very compact and controlled in size in order to be easily, conveniently and reliably installed on top of towers and in dense urban environments, which requires the coaxial interconnection system that carries the RF signal to be more compact. Traditional cumbersome cable assembly connections are being replaced by simple, compact, reliable "board-to-board" coaxial connector connections that can carry more than 100W of RF signal power at the same time. Now more and more RF and structural design engineers are becoming more familiar with the board-to-board connectors, and more and more designs are using board-to-board connector connections, which makes designers more and more cost considerations, the market needs to design simpler, lower-cost board-to-board connector solutions. Connector size continues to get smaller brings in the mechanical design challenges in two main

Connector the industry is very large, and its many types, such as IT host internal connectors, host peripheral connectors (I/O), equipment connectors, cell phone connectors; industrial connectors, automotive connectors, new energy connectors and so on; I through the exchange of connectors and connectors and the collection of relevant market information, and you come together to understand the basics of the connector Imagine if there is no connector will be how? This circuit between the continuous conductor to be permanently connected together, such as electronic devices to be connected to the power supply, you must connect the two ends of the wire, and electronic devices and power supply through some method (such as welding) fixed firmly; in this way, both for the production or use, have brought a lot of inconvenience. Take the car battery for example; assume that the battery cable is fixed welded to the battery, the car manufacturer to install the battery will increase the workload, increasing production time and costs; battery damage needs to be replaced, but also to send the car to the repair station, desoldering to remove the old, and then welded on the new, to pay more labor costs; with a connector can be free of many troubles, buy a new battery from the store, disconnect the connector, remove the This simple example illustrates the benefits of connectors; it makes the design and production process easier and more flexible, reducing production and maintenance costs. The benefits of using connectors: it makes the design and production process easier and more flexible, and reduces production and maintenance costs.

The basic performance of the board-to-board connector The basic performance of board-to-board connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance. 1 mechanical performance on the connection function, plugging force is an important mechanical performance. Insertion force is divided into insertion force and pull-out force (pull-out force is also known as separation force), the requirements of the two are different. In the relevant standards there are greater insertion force and minimum separation force provisions, which indicates that, from the point of view of use, the insertion force to be small (so that there is a low insertion force LIF and no insertion force ZIF structure), while the separation force if too small, it will affect the reliability of the contact. Another important mechanical property is the mechanical life of the board-to-board connector. Mechanical life is actually an indicator of durability, in the national standard GB5095 to call it mechanical operation. It is an insertion and an unplugging as a cycle, to the specified plugging cycle after the connector can normally complete its connection function (such as contact resistance value) as the basis for judging. Board-to-board connector plugging force and mechanical life with the contact structure (positive pressure size) contact parts plating quality (coefficient of sliding friction) and the size of the contact arrangement accuracy (alignment) related. 2. Electrical performance mainly includes contact resistance, insulation resistance, current and electrical strength Contact resistance: high-quality

What do you need to pay attention to when storing the board-to-board connectors? Board-to-board connector insulation inspection rules: qualified suppliers produce the same type of insulation material, product performance is stable (within one year without quality problems and returns), every 5 tons of sampling. The new insulating material of the qualified supplier or the insulating material or sample of the sub-supplier should be sampled for type test, and the five deliveries thereafter should be sampled for inspection, and after passing the test, it can be transferred to other batch sampling. If the insulating material is found to be unqualified once, the sample shall be sampled according to the first batch of supply. For each batch of insulation material must be accompanied by the supplier's material quality guarantee or test report. Sampling method: 2 bags or more per batch. The detectable items are tensile strength, elongation at break, dielectric strength, volume resistivity, volume resistivity at 80℃, oxygen index and density. For the performance that can not be tested according to the manufacturer's test report or quality assurance book acceptance. The insulating material is packed with plastic film bag inside and PP woven fabric/kraft paper compound outside, with net weight of 25±0.2kg per bag, but no negative deviation is allowed per ton. Board-to-board connector insulation material packaging must indicate: the name of the manufacturer, material type and name, production date, net weight and product certification and other signs. Electronic wire connector insulation material into the factory, should be accompanied by the manufacturer's quality assurance certificate or

How to solve connector problems At present, electronic connectors are increasingly used in everyday life. Due to the small size of such devices, various situations often occur in use. For some common failures, we also need to do the appropriate analysis work. When the failure occurs we should do? Poor contact From a structural point of view, the metal conductor inside the connector is the core part of the entire device, used to connect the voltage or current of the external wire or cable, data signals equal to their mutual fit, were transmitted to the mutual fit connector contacts. Therefore, the design of the connector requires an excellent structure, good stability and good electrical conductivity. There are many reasons for this situation, such as poor design of the contact part of the connector, material selection problems, or processing dimensions do not meet the design requirements, rough or uneven installation methods can lead to poor connection between the connector and the connector. equipment. Therefore, one of the issues to consider when electronic equipment fails is the contact problem. All connectors must be checked. If the connection is tight, then other problems must be considered. It is not an internal connection problem. Poor insulation This refers mainly to the influence of the external environment. Usually the performance will be unstable in this case, and the leakage will be terrible, which will cause unsafe factors in use and can be observed visually. However, when this problem occurs, it must be directly shut down and replaced. Connector. Another issue involved here is the cause of poor insulation. Due to excess substances o

There are many types of connectors and a wide range of industries that use them. But the production process is basically the same. Generally divided into four steps: stamping, plating, injection molding, assembly. 1 Stamping The manufacturing process of electronic connectors generally start from stamping pins. Electronic connectors (pins, terminals) are stamped from a thin metal strip by a large high-speed stamping machine. One end of the large roll of metal strip is fed into the front of the press, and the other end is rolled into the take-up wheel through the hydraulic table of the press, and the metal strip is pulled out of the take-up wheel and rolled out of the finished product. 2 Electroplating After the terminals and pins are punched, they should be sent to the plating section. At this stage, the electrical contact surface of the connector is plated with various metal coatings. During the process of feeding the stamped pins into the plating equipment, the pins can be twisted, broken or deformed. Such quality defects can be easily detected by the inspection techniques described herein. However, many quality defects in the plating process are still "off-limits" to inspection systems for most machine vision system providers. Electronic connector manufacturers need inspection systems that can detect inconsistent defects, such as small scratches and pinholes in the plated surface of connector pins. Although these defects are easily identified on other products, such as the bottom of aluminum cans or other relatively flat surfaces; the irregular and angled surface design of most electrical connectors makes it difficult for visual inspection syst

Connectors are electromechanical components that connect electrical circuits. Therefore, the electrical parameters of the connector itself is the first issue to consider when selecting a connector. The correct selection and use of electrical connectors is an important aspect of ensuring the reliability of the circuit. Electrical connectors (hereinafter referred to as connectors) can also be called plug holders, widely used in a variety of electrical circuits, the effect of connecting or disconnecting the circuit. Progress in the reliability of the connector is first of all the responsibility of the manufacturer. However, due to the complexity of the connector type, the use of a wide range, therefore, the correct selection of connectors is also an important aspect of the progress of connector reliability. As long as the manufacturer and the use of the two sides of the joint efforts, in order to Z maximize the function of the connector should play. Connectors have different classification methods. According to frequency, there are high-frequency connectors and low-frequency connectors; according to the shape of a circular connector, rectangular connectors; according to the use of points, there are printed circuit board connectors, cabinet connectors, audio equipment connectors, power connectors, special connectors and so on. The following is the primary discussion of low-frequency connectors (frequency of 3MHZ or less) selection methods. Electrical parameters required Connectors are electromechanical components that connect electrical circuits. Therefore, the electrical parameters of the connector itself is the first issue to consider when selecting a connector. Additional voltage

An electrical connector, also known as a circuit connector, is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to the other. An electrical connector is a motor system that provides a separable interface to connect two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines become the connector or the bridge between the two. Electronic connectors are devices that transmit electronic signals (analog signals or digital signals) and provide a separable interface to connect two sub-electronic systems, and are components used to complete the electrical connection between circuits or electronic machines. Such as: power plugs / sockets, IC feet, telephone line plugs, etc. are. Widely used in the electronics industry. Electronic connector is a motor system, which can provide a separable interface to connect two sub-electronic systems, in short, to complete the electrical connection between the circuit or electronic equipment and other components become the connector that is the bridge between the two. Electronic can be used as the electrical/electronic transmission connection between circuits, components, and systems, so that power, signal, and current can flow stably and reliably, and to facilitate product assembly, maintenance, and replacement. Materials of electronic connectors The choice of materials is based on processing and molding, product application and strength properties of a comprehensive consideration; the cost of electronic connectors by the price of materials, processing difficulties and production efficiency vary; electronic connector materials mainly contain insulator materials (plastic ra
