How to use the pin header correctly?

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.
Pin Header Konnra Electronics
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.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and

Talking about the function, classification and working principle of OTG data line

  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mobile devices wi

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con
