(Summary description)The optimization of electrical performance can consider the control of the film contacting the electroplated surface. One of the main requirements for the electrical performance of the needle and catchment strip is to set and maintain a stable impedance of the needle and catchment strip. In order to achieve this goal, a metal contact interface is required to provide this inherent stability.

Do you know what factors affect the contact performance of the pin headers? Follow the editor of Cheapest 2.54mm pitch pin header to have a simple understanding!


The optimization of electrical performance can consider the control of the film contacting the electroplated surface. One of the main requirements for the electrical performance of the needle and catchment strip is to set and maintain a stable impedance of the needle and catchment strip. In order to achieve this goal, a metal contact interface is required to provide this inherent stability. After setting up this contact interface, you can avoid or separate the surface mask during contact mates. The difference between precious metals or rare metals and ordinary metals determines the difference in pin header applications.
To a certain degree of color matching, precious metal coatings (such as gold, palladium and their alloys) basically do not include surface films. For this kind of coating, it is relatively simple to make metal contact on the interface. Because only the movement of the surface partner needs to be touched during the fitting process. Usually this is easy to achieve. In order to maintain the stability of the contact interface impedance, the design of pins and junction bars should maintain the precious metal on the contact surface to prevent the influence of external factors such as pollutants, base metal diffusion, and contact wear.
The above is the editor of Cheapest 2.54mm pitch pin header: a brief introduction to the relevant little knowledge about the pin header.

Cheapest 2.54mm pitch pin header introduces the soldering knowledge of the header

Place the soldering iron tip on the pin header and the soldering surface, and then feed the solder wire in 1 second. Remove the solder wire first when appropriate, and then remove the soldering iron. Because the solder paste is applied in advance, the solder wire will naturally fit the welding surface after melting, making it easy to fit and weld.
