What is a pin header and how to choose?
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, which is often used in the design. The choice of pin headers is also very important.
The pin headers can be divided into: single row, double row, 3 rows, 4 rows, and currently up to 4 rows.
The development of pin headers is becoming more and more miniaturized. Since many product faces have to face smaller and lighter development, there are certain requirements for the spacing and appearance, and the requirements for the products will be more precise, such as wire pairs. The better choice of the board is small pitch 0.6mm and 0.8mm, high density, high speed transmission, high frequency direction development. Miniaturization means that the center of the pin header is smaller, which is the PIN distance often mentioned in the industry. High density is the inevitable result of achieving large core number.
The role of the pin header is to connect the circuit and take on the task of current or signal transmission. It is usually used in conjunction with the motherboard to form a board-to-board connection; or used 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 the electronic designers from underestimating the importance of single-row needles in the design process, we have made some suggestions for this because of the small loss. That is to have a two-bar design idea when designing; there is also a strong design and so on.
The raw materials in the pin header are white and bright, and the color is between silver and nickel. The initial solderability is acceptable. The solderability is reduced when the temperature is high or the long-term storage is severe. The gold-plated bottom layer of the original ornament used for contact with the human body can also be used for the whiteness of the electrical performance, which is not required to have high resistance to color change, and has a certain weldability requirement.
Therefore, how do we choose the pin header? When selecting a pin header, people first consider the cost control, others are high quality, high stability, and the design features of the pin header itself. In fact, to put it bluntly, the choice of pin headers is both durable and cost-effective, and it is also suitable for your own use. Therefore, alternative manufacturers have become an excellent choice. Not only is quality in place, but price is also a big advantage, and the greater advantage is reflected in the delivery date.
