The important reason for humidity test in connector test

After the connector is shipped, there are many important links, such as production links, such as testing links. When we talk about the test link, we must not get around an important point, that is, the humidity test in the connector test link, which occupies a very important position. Because the humidity test can ensure the ability of the product to withstand higher humidity and cycle temperature, Konnra connector engineers focus on introducing you to the humidity test in the connector test link. For the humidity test, we will explain from two points, the first is what is the humidity test of the connector, and the second is how to test the humidity of the connector, the specific content is as follows:

First, what is the humidity test of the connector

Konnra connector engineers pointed out that since condensation on parts can cause failures, it is very important to understand the function of the connector group being used. Failures caused by humid environmental factors may appear in the form of corrosion of the coating and lead to reduced electrical performance. The humidity test takes this into consideration by setting the mating connector to a different temperature range of 25°C – 65°C and a relative humidity range of 90%RH – 98%RH within 10 days.

Second, how to perform the connector humidity test

To determine how the connector kit responds to the humidity test, the parts will pass, mating/unmating, IR/DWV and LLCR before and after exposure to moisture. Solder the connector kit to the appropriate test board, and then perform the initial baseline test. Afterwards, perform a humidity test on the parts indoors and then retest to determine whether they passed the humidity test. It should be noted that if the connector fails the electrical requirements of LLCR or IR/DWV, the connector is considered to have failed the humidity test. The standard for humidity testing by the regular connector manufacturers is usually EIA-364-31 "Humidity Test Procedure for Electrical Connectors and Sockets" as the test standard for humidity testing.

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
