#pin header

Speaking of the pin header, as a component practitioner, how much do you know? Do you know what effect the plating of the pin headers has? The following Konnra Electronics engineers will introduce you to the role of the pin plating. I hope that through our explanation, you will have a deeper understanding of the plating effect of the row of pins.

The optimization of electrical performance can be considered from the control of the film on the surface of the contact plating that is already present and about to be formed. A major requirement for the electrical performance of the pin headers is to establish and maintain a stable pin header impedance. To achieve this, a metal contact interface is required to provide such inherent stability. Establishing such a contact interface requires that the surface film be able to avoid or split during contact engagement. These two different options clarify the difference between precious metals or rare metals and ordinary metals.

To varying degrees, precious metal coatings (such as gold, palladium and their alloys) are essentially free of surface film. The metal contact that creates the interface for these coatings is relatively simple because it only requires movement of the accompanying surfaces of the contact surfaces during mating. Usually this is easy to implement. In order to maintain the stability of the contact interface impedance, the design of the pin header should be designed to maintain the precious metality of the contact surface to prevent external factors such as contaminants, diffusion of the substrate metal, and contact wear.

About the concept and classification of the Female header connector How much do you know, the electric bee optimization engineer pointed out that the Female header is a type of connector, commonly known as the Female header connector. Because in most cases it is used with the "pin header connector", the role and scope of the Female header connector is basically the same as that of the header connector.

According to Konnra Electronics, the Female header connector is widely used on PCB boards in electronics, electrical appliances, and instrumentation products. Its role is to function as a bridge before being blocked or isolated in the circuit. The task of current or signal transmission. It is generally used in conjunction with the pin header connector to form a board-to-board connection, or used in conjunction with an electronic harness to form a board-to-wire connection, or it can be used independently for board-to-board connection.

Classification:

1, Female header according to the spacing: 0.8mm, 1.0mm, 1.27mm, 2.0mm and 2.54mm spacing.

2, Female header according to the height of the plastic and whether there are bumps, the bumps are divided into: semi-convex and full convex.

3, According to the number of rows of pins: there are single row, double row, 3 rows and 4 rows, the current maximum is 4 rows.

4. According to the installation method: 180 degrees is represented by "V", 90 degrees is represented by "R", and SMT is represented by "S".

5, According to whether it needs to be increased, whether it needs to be positioned to divide the column, there are two kinds of positioning columns: one is the inner positioning column, and the other is the ear positioning column.

Female header terminal type: U-shaped terminal and Y-shaped terminal

U-shaped terminal, contact with three faces, generally U-shaped terminal with low plastic height.

After the user purchases the pin header, there are some precautions that must be kept in mind during the use. If you ignore these precautions, it may affect the performance of the pin header. Then the user uses the pin header. What are the operational considerations for the mother when it is discharged? The following Konnra Electronics engineers will give you a detailed explanation of what to do when using the pin header.

In the operation of the row of pins, there are five main points to note, as follows:

1. Heat dissipation design The pin header will generate heat during operation. If the temperature is too high, it will affect the attenuation speed and stability of the LED. Therefore, the heat dissipation of the PCB board and the ventilation and heat dissipation of the cabinet will affect the pin header.

2. Check if the anti-static pin headers have good anti-static measures.

3. The smaller current value of the pin header is 20 mA. It is generally recommended that the maximum current used is not more than 80% of the nominal value. Especially for electronic devices with small dot spacing, due to poor heat dissipation conditions, Reduce the current value.

4. Control the verticality of the board. For the in-line type of pin headers, there must be enough process technology to ensure that the LEDs are perpendicular to the PCB.

5. Over-wave soldering temperature and time must be strictly controlled for the wave front welding temperature and furnace time. The preheating temperature is 100 °C ± 5 °C, the maximum is not more than 120 °C, and the preheating temperature rise is required to be stable. The welding temperature is 245 °C ± 5 °C. The recommended welding time is generally not more than 3 seconds.

If you want to understand a product in depth, you can't get rid of its performance and features, and the pin header is no exception. So what are the performance and characteristics of the pin headers? The following Konnra Electronics engineers used an article to let you know what the performance characteristics of the pin headers are. I hope our introduction will help you.

1. Operational convenience and mechanical strength of the pin header are also important factors. The connector is usually the interface between the PCB main board and the external components. The receiving capacity of the pin header is very strong, and sometimes it may encounter considerable external force and is intact.

2. The components assembled by through-hole technology are much higher in reliability than the corresponding SMT components. Whether it is strong pulling, squeezing or thermal shock, it can withstand without being easily detached from the PCB.

3. The pin header processing for field wiring in the industrial field is usually a high-power component, which can meet the needs of different transmission of high voltage and large current.

4. These advantages are diminished with the reduction in component adhesion on the PCB. The pin header element is characterized by a compact design and easy placement, and the pin header of the through hole is significantly different in size and assembly form.

5. With electrical strength, refers to the ability to withstand the rated test voltage between the pins, between the contacts, or between the contacts and the casing.

6. The general pin header can adapt to the attenuation caused by electromagnetic interference and the ability to shield electromagnetic interference.

7. The contact resistance of the pin header, the contact resistance is small, and can be as small as several tens of milliohms.

As a practitioner in the connector industry, it is not unfamiliar to the pin header, but if you ask what is the pin header, it is estimated that it cannot be accurately expressed in words. So what is the pin header? In the following,Konnra Electronics engineers will give you a detailed introduction of what the pin header is. I hope that after the introduction of the engineer, you can have a deeper understanding of the pin header.

Konnra Electronics engineers pointed out that pin headers are widely used in connectors for pcb boards and have the reputation of universal connectors. Generally used with the mating, line end and other connectors. With the intensification of competition in the pin header connector market, some manufacturers are now reducing the cost from electroplating (imitation gold) and materials (green steel, alloy, etc.), but also reduce the use characteristics and life of the product.

Pin header, a type of connector. This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters. Its function is to function as a bridge between blocked or isolated circuits in the circuit, and is responsible for current or signal transmission. task.
