What is the main function of pin header connector? How to choose?
2021-08-10
In electronic components, product design often has a strong correlation with its performance. Good design can not only improve the aesthetics of the product, but also extend the service life of the product. Today we will talk about the knowledge of pin headers in connectors.
According to the number of rows, it can be divided into single row, double row, three row, four row, etc. The current maximum is 4 rows. The development of pin headers is getting smaller and smaller, because many products are geared towards smaller and lighter development, and there are certain requirements for spacing, appearance size, and height. The requirements for products will be more precise, such as better choices. Circuit boards are developing towards small spacing of 0.6mm, 0.8mm, high density, high-speed transmission, and high frequency. Miniaturization refers to the small center distance between pin rows, that is, the PIN pitch, and high density refers to the realization of a large number of cores.
The function of the pin header is to connect the circuit and undertake the task of current or signal transmission. It is usually used in conjunction with a header to form a board-to-board connection; or in conjunction with a wire harness to form a board-to-wire connection; it can also be used independently for board-to-board connection. In order to prevent electronic designers from underestimating the importance of a single row of pins during the design process, we have put forward some reference opinions. In other words, the design must have the design concept of parallel bars; it must have a strong design and so on.
The material the head is made of is white and shiny, with a color between silver and nickel. The initial solderability is acceptable, but the solderability is severely reduced after high temperature aging or long-term storage. Originally used for body contact decoration, gold-plated underlays are now also available in white shades with lower electrical performance requirements but higher resistance to tarnishing.
Having said so much, how should we choose pin headers? When people choose pin headers, they first consider cost control, followed by high quality, high stability, and the design features of the pin headers themselves. In fact, to put it bluntly, the choice of pin headers should be durable and inexpensive, but it should also be suitable for your own use. Therefore, alternative manufacturers become an excellent choice. Not only the quality is on point, but the price is also one of its main advantages. The greater advantage is reflected in delivery time, which is also the reason why there are more and more domestic alternative manufacturers.
When selecting a pin header connector, there are several key factors to consider:
Size and spacing: Pin header connectors are available in different size and spacing options, such as pin pitch and row spacing. Depending on your application needs and the type of device being connected, it is important to select the appropriate size and spacing.
Current and Voltage Requirements: Choose a header connector with sufficient capacity based on the current and voltage requirements of your circuit board and connected devices. Make sure the connectors you select are rated for the current and voltage required for your application to avoid overloading or electrical failure.
Reliability and durability: Pin header connectors should have good reliability and durability and be able to withstand long-term use and plugging and unplugging operations. Please review the connector's technical specifications and material quality to choose a product with high quality and reliability.
Environmental adaptability: Consider your application environment, such as temperature range, humidity and vibration. Make sure the pin header connector you select is capable of adapting and functioning properly under specific environmental conditions.
Installation and connection methods: Pin header connectors have different installation and connection methods, such as direct plug-in, surface mount (SMT) or pin type, etc. Choose the appropriate installation and connection method based on the design requirements of your circuit board and device.
