Pin headers are widely used in PCB board connections and are known as universal connectors. They are usually paired with female headers, wire terminals and other connectors. With the competition in the pin header connector market, some manufacturers are now reducing costs by improving electroplating (imitation gold) and materials (green steel, alloy, etc.), but this also reduces the product's usability and lifespan.Pin header, a type of connector, English name: Pin Header. This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to act as a bridge between blocked or isolated circuits within the circuit, and to take on the task of current or signal transmission.

The function of the female connector:This circuit is blocked before the blocking or isolating circuit, as a bridging function, assuming the task of current or signal transmission. The headlight connector is mainly used for the transmission of signals and images between the front and rear seats required by modern luxury cars, and other customized connectors are widely used in dashboards, antennas, vehicle information interconnection, intelligent transportation systems, electronic non-stop toll collection systems, etc. The bull connector is usually composed of a square plastic socket and a number of neatly arranged square pins. The difference between the connector and the bull connector is that the simple bull removes the buckles on both sides. Usually used with pins to form a board-to-board connection; or used in conjunction with a board-wire electronic wiring harness; or independently connected to the board to board. Classification of female connectors:

A、Main Features:①Miniaturized, compact, high-density manufacturing②Save space③Simplify wiring procedures, easy connection④Save labor costs⑤Excellent flexibility, flexible application, foldableB、Normal product pitch:①Cable pitch：0.3mm、0.5mm、0.8mm、 1.0mm 1.25mm, 2.0mm 2.54mm②Cable length：15mm～ANY③Cable type：A、B、C、D、E、F、G、H、I、J、K④EMI catagory：Copper foil, aluminum foil, copper foil Mylar, aluminum foil Mylar, conductive fabric, silver paste treatment, absorbent, etc.

The basic reason for connector testing is to confirm the performance of the connector. In addition to design confirmation testing (performed on models or trial production samples) to verify the effectiveness of the design, most connector tests are based on test specifications or identification test procedures to confirm the performance of the connector. Generally, it includes environmental testing, mechanical performance testing, and electrical performance testing. The test procedures, measurements, and acceptance criteria are related to the application scenarios and market requirements of the connector. For general applications and general markets, the test requirements and acceptance criteria are also more general.When the specific application environment becomes the focus of the test program, the test conditions will be more specific and accurately reflect the actual application conditions, as will the measurements and acceptance criteria. This is called performance confirmation testing.

The design of medical devices is highly dependent on efficient underlying electronic interconnection systems. Therefore, connector design and the selection of the right connector are critical.When designing medical devices, engineers face many challenges and extremely complex choices that would not occur in other industries. Medical devices need to be durable and reliable, and the operating conditions are often very harsh, including factors such as liquids, sterilization, physical interference and electromagnetic interference, and extremely high plug-in and unplug cycles.These types of medical devices are highly dependent on the effectiveness of the underlying electronic interconnection system. Connector design is an integral part of the design process, and choosing the right connector is critical.The first factor engineers consider is deciding whether to use an off-the-shelf connector, a hybrid version, or a custom solution. Off-the-shelf connector products are already available in the market and are available in a variety of configurations. These products tend to require lower engineering and tooling investments, but have longer lead times and higher unit costs. Hybrid versions offer customized overmolded features on existing connectors. These products improve performance and aesthetics over off-the-shelf products, and have lower design and engineering costs than fully customized connectors, but have longer lead times. Custom solutions are products designed and manufactured for a specific customer, device, or application. Using a customized connector makes it easier to integrate components or electronic components, as well as add marking or logos. The initial investment in engineering and tooling is generally higher, but, depending on production volume, these solutions can be more cost-effective in the long run.
