What are the influences of environmental factors on din 41612 type e connectors manufacturer? For example, in the process of transportation and storage, in the process of manufacturing, in the process of installation, maintenance and use by the end customer. These environmental factors can be understood as a given situation, which can be subdivided into temperature, humidity, corrosion, pollution, internal and external conditions, and human factors. What we also want to say is the duration of exposure to changing conditions in these environmental factors.

Storage and transportation

The first two environmental factors, warehousing and transportation, are easy to understand. They affect all kinds of products, so most purchasing, sales, operations and engineers have some experience with them.

Storage environments in din 41612 type e connectors manufacturers vary from controlled clean, heated or air-conditioned, damp warehouses, offices or factories, to uncontrollable corresponding environments. In the case of heat, moisture or corrosion, it will seriously affect the service life of the terminal. In these uncontrolled environments, the weldability storage life will be reduced due to oxidation, corrosion, and the intensification of intermetallic combination. The surface and function of metal devices can be affected by rust, patina and other forms of corrosion; Plastics as insulation materials are also affected by the degradation of flexibility, strength and shape. din 41612 type e connectors manufacturer Storage life can be long or short, as long as a few months or years, as short as a few days or weeks, some need to make a long-term inventory plan for the customer, while others order production immediately out of storage. By adopting a first-out inventory strategy, traceable date labelling system, appropriate packaging, corrosion protection, improved storage conditions and appropriate din 41612 type e connectors manufacturer materials and design, Improves the reliability and storage life of the din 41612 type e connectors manufacturer.

Transport environmental factors are related to problems caused by vibration and collision caused by transport vehicles and other mechanical devices, road surfaces, loading and unloading tools during operation. Extreme temperatures often combine and exacerbate the effects of vibration and collision. din 41612 type e connectors manufacturers are often exposed to salt spray in Marine transport. Transport time is generally predictable, land and air transport is generally a few days, while sea transport is as long as a month or months. din 41612 type e connectors manufacturer and packaging materials must be resistant to decomposition, deformation, corrosion and extrusion if they are to remain intact during transport. The following measures are usually taken to improve the reliability of transportation and make the goods reach the destination smoothly: Use a reputable carrier with appropriate packaging materials, robust internal and external packaging boxes, suitable lining or stuffing, necessary corrosion protection and appropriate din 41612 type e connectors manufacturer material and design method.

Welding condition

The obvious difference in welding conditions depends on the type of din 41612 type e connectors manufacturer and the steps of the welding process. The din 41612 type e connectors manufacturer for wave soldering, mounted on a PCB board, is a typical perforated mounting type. The needle of the hole must be accurately positioned, properly sized, evenly placed, and have good weldability, which is conducive to insertion and welding. During the entire assembly process, the high temperature in the preheating zone and the temperature transmitted to the terminal body by wave soldering must be withstood. The flux shall not affect the terminal, and there shall not be any residue. The entire assembly process must be able to be washed with water. Preheating temperatures often reach 100°C or higher, and crest temperatures of 280°C are not uncommon. The sudden high temperature often causes the terminal to melt, twist, bubble and deform. Assembly time is generally divided into a few minutes of exposure to flux, a few minutes of warm-up period, a few seconds of crest period, and a few minutes of cleaning and drying period. Selecting appropriate metal materials and resins can improve the reliability of welding.

For reflow soldering, the din 41612 type e connectors manufacturer is generally surface mount or through-hole mount. The surface-mounted solder needle must be in the correct position, the right size, fully coplanar with the PCB board or can be micro-floated to accommodate all tin pans on the PCB board to ensure sufficient strength, process quality and circuit reliability (no break, see figure 1). The needle of the hole must be accurately positioned, properly sized, evenly placed, and have good weldability, which is conducive to insertion and welding. In the whole assembly process must withstand the high temperature impact caused by heat treatment, in the welding mainly use infrared preheating and convection preheating to conduct heat to the welding needle and tin plate interface to melt the solder paste. It is not necessary to force a cleaning afterwards, but it is generally expected. The temperature in the preheating zone is generally set to a peak of 230°C, with higher temperatures after a few minutes. As with wave soldering, the sudden high temperature often causes the terminal to melt, twist, foam and deformation. Assembly time is generally divided into a few minutes warm-up period, a few seconds peak, and a few minutes cleaning and drying period. Of course, the choice of appropriate metal materials, resins can improve the reliability of welding.

Through terminal blocks, electronic modules, and ceramic terminals are often manually assembled, and reliability depends mainly on human factors during operation, such as driver strength, torque during wire tightening, and the degree of screw tightening installed on the board. Excessive torque or uncontrollable screw fastening force will seriously affect the connection performance, sometimes the performance is obvious, sometimes it is not easy to be detected when wiring in the field, when over a period of time, weeks or months after use.

The end use is extremely important as it plays a crucial role in the raw material requirements of the terminals, the assembly configuration and the combined cost of the din 41612 type e connectors manufacturer. Comprehensive costs include the cost of procurement, repairs and maintenance of the din 41612 type e connectors manufacturer. Customer satisfaction and manufacturer credibility are also part of the cost equation.

The following factors need to be considered:

Places of application, such as internal or external, tropical or maritime, stationary or mobile (e.g. passenger or engine areas in motor vehicles)

Temperature and humidity normal range and extreme conditions

When the circuit is opened or closed, the temperature in the case during use or near the heat source;

Exposure to contaminants, dust (conductive or non-conductive), corrosive gases or liquids;

Exposure to vibration, collision, voltage spike, current overload environment;

Lower rating principle - When environmental conditions become extremely severe, engineers should lower the rating of components;

Human factors, including district wiring and torque levels, strength and misuse during installation and maintenance;

Relevant laws and regulations, some requiring UL, CSA or other certifications, these certifications involve flame retardant performance, electrical clearance and creepage distance, insulation voltage, impulse withstand voltage and other hazard testing and performance standards;

Clear or unclear statements of customer requirements

conclusion

The performance of the din 41612 type e connectors manufacturer across storage, transport, welding, assembly and end-use environments is no accident, it is the result of careful design, development and careful application handling. In the era of globalization, the cost of a product not only includes the cost of procurement, but also must take into account the performance of the product in a range of application environments.
