In the process of new product development, risk control needs to be considered in advance. There are four basic approaches to risk control: risk avoidance, loss control, risk transfer, and risk retention. Risk avoidance is the intentional abandonment of risky behaviors by investment entities to completely avoid specific loss risks. Simply risk aversion is the most negative way to deal with risk, because investors often give up potential target returns at the same time they give up risky behavior. Therefore, this method is generally used only in the following situations: 1. The investment subject is extremely averse to risk. 2. There are other solutions that can achieve the same goal, and the risk is lower. 3. Investment entities are unable to eliminate or transfer risks. 4. The investment entity is unable to bear the risk, or the risk cannot be adequately compensated. Loss control is not abandoning risk, but making plans and taking measures to reduce the possibility of loss or t

Efficient and orderly warehouse management is related to the prosperity of the company! So, what are the pain points of electronic component warehouse management? 1. There are many product models, and the storage personnel have a long time to get started. The number of electronic components is large and the name is complicated, and the material numbers are similar. It takes a long time for the novice to understand the materials to achieve independent receipt and delivery. 2. Warehouse physical and system inventory will never be right. Because the warehousing process is not standardized, the personnel operation is not coordinated, the warehouse staff misplaces the data, and the interval is relatively long. When the inventory is known, the data is abnormal. There is no way to query the person in charge of the problem and cannot manage it from the system. 3. The warehousing personnel take the wrong goods, the marking personnel mislabeled, or the labeling is misplaced, which will

In modern industrial production, due to the processing machinery and manufacturing principles, the production environment is difficult, and there may be a lot of heat, dust, moisture, corrosive liquids and vibrations. These can affect the life of the components and connectors. Therefore, when manufacturing RJ45 connectors for industrial applications, not only waterproof and dustproof, but also signals cannot be lost, and the following three requirements must be met. First, the transmission speed is faster：Productivity is critical to industrial production, and data transfer is one of the important steps to increase efficiency and increase production. This is a technology that RJ45 connector manufacturers need to focus on. Second, good mask function:Good mask function is not only waterproof and dustproof, but also protects against external signal interference and noise. There are many electronic devices in the factory, so signal interference is a serious problem. To ensure more st

The yeahui connector can meet customers' needs for miniaturization, high performance, versatility, high speed, high temperature resistance and high current. The products are not only highly reliable, but also rich in fields, including communication equipment, automobiles, medical equipment, industrial equipment, agriculture, ships and so on. Because the times are advancing, people have a wide range of connector applications in real life, so connector manufacturers are very strict in quality control, because the production connectors use some sophisticated product testing or connection, if their own quality management system is not enough If you go to check the quality of the product, it will be a bad news. All the connector manufacturers must have a formal quality management system in production. The quality of the product must be strictly controlled. In the production connector, mainly follow the four steps of PDCA, which can be applied to many product quality management. T

Advantages of metal connectors: 1. Metal connectors are durable. 2. The metal connector is adapted to high temperatures. 3. Metal connectors may require stainless steel in a food grade/aseptic environment. 4. Metal connectors

The first is heat resistance, and the waterproof connector has good adaptability at both high and low temperatures. The maximum temperature can reach 200 °C (except for a few high temperature special waterproof connectors) and the minimum temperature can be as low as -65 °C. Due to the resistance, the device generates a lot of heat under electric working conditions and the device heats up. So the temperature we usually refer to consists of ambient temperature and contact temperature. The second is that the waterproof connector can effectively adapt to the salt spray resistant environment. Generally structural metals, the contact surface may have electrochemical corrosion. We cannot avoid the salty and wet working environment. However, the performance of the waterproof connector can be improved to prevent the device from being corroded, and the performance of the connector is generally tested by a salt spray test. A certain concentration of NACL is used to compress the air to crea

RJ45 is an important interface part in the network connection. It is a kind of plastic connector that is inserted in a fixed direction and automatically prevents falling off. It is used for network communication. Because it looks like crystal, it is also called crystal head. Mainly used to connect network card ports, hubs, switches, telephones, etc. ​ When making the crystal head, make the shrapnel of the crystal head face outward, the entrance line is facing down, from left to right, follow the above line sequence, fully insert the line, and then clamp it with the cable clamp. 1. Cross-line connection is used between devices of the same type, and straight-through lines are used between different types of devices; 2. The router and the PC belong to the DTE type device, and the switch and the HUB belong to the DCE type device. 3, RJ45 network connector practice generally by 568A and 568B two standard practices, according to the same standard on the straight line, the differen

1. When the wire harness is subjected to two PVC moldings, it is not allowed to be packaged, and product inspection is required. 1. Check the length, appearance, and functional test of the product. 2. Inspection and confirmation before product packing. 3. The shaving edge, the appearance of the full inspection, the first confirmation of the package. 4. Inspection and confirmation of outgoing materials before shipment. Functional tests include: the label is wrong, the material is wrong, the terminal is PIN, and the plastic bag is wrong. 2. The problems that should be paid attention to when packaging and packaging are: product specifications, quantity, and packing method. First, the wire plastic bag is packaged, and the packaging method is in accordance with the drawing standard. Packing and assembling methods should also be in accordance with the drawing standards, confirmation before packing, weighing, and filling out the label outside the box. 3. After the packing is completed,

Molding requires the use of an injection molding machine. Its function is to use thermoplastic molding or thermosetting materials to produce corresponding shapes according to customer's drawings. ​ The injection molding machine works like the working principle of an injection syringe. The plasticized molten state (i.e., viscous flow dynamics) is injected into the closed chamber by the thrust of the screw (or plunger). The process of obtaining the product after curing and curing. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticizing - pressure injection - mold filling cooling - mold extraction. After removing the plastic part, close the mold again for the next cycle. There are three main aspects after the completion of molding. The first is the appearance quality, including integrity, color, gloss, etc.; the second is the accuracy between size and relative position; the third is the physical properties and chemical pro

The basic task of the test is to obtain useful information, through the use of specialized instruments and equipment, design reasonable experimental methods and necessary signal analysis and data processing, so as to obtain information related to the tested object.The final result of the test is to input the displayed information into the information processing library for control. After the wiring harness assembly is completed, it must pass the first test to test whether the assembly is qualified. It can check whether the line position conforms to the drawing standard, whether the PIN is returned, and whether there are high and low needles.Whether the current is up to standard, whether the resistance is too large or too small, the wiring harness is required to be 100% energized, and the various electronic components added on the wiring harness can be tested to verify whether it meets the service standards.Connector and test head matching standard.If it does not meet the standard,

Wire harness assembly process must be familiar with the product, familiar with the product to know how to look at the drawings to assemble, through product inspection focus and problems, master the key points of the product, improve operational skills, improve product qualification rate. Inspection focus: 1 rubber core, connector or socket specifications. 2 PIN point requirements. 3 After the assembly is completed, there is no return pin, the terminal is skewed, and the single force phenomenon occurs. 4 visually measure high and low needles. 5 two or more people need to be labeled when assembling, to facilitate subsequent process inspection. Assembly first steps: 1 look at drawings, processes, record sheets; check materials, connectors, rubber cores; pay attention to past abnormalities, new products; 2 understand wiring method, rubber core PIN point front diagram; 3 first self-test Sampling of the assembly process, must check items: 1 must check items: whether the terminal is

The manual soldering technique is to melt the solder at a certain temperature, and the molten solder is spread along the surface of the weld by capillary suction to form a wett of the solder and the weld, and the weld is firmly bonded to the core of the wire. Has good electrical conductivity. The crimping technology is to apply a certain pressure to two specific metal surfaces by a crimping tool or equipment at normal temperature, so that the metal joints can be properly plastically deformed to produce a reliable electrical connection, which has good mechanical strength and excellent Electrical performance and environmental resistance. We also need to understand the terminals. The terminals are the main components for wire processing. There are many types of terminals. The crimp terminals need to use the open terminals, and the wires are placed on the terminals of the crimping parts from the side. Most of the welding terminals can be welded, but the working hours are large, the te

With the rapid development of the times and the advancement of science, we will choose to use automated machinery in the production process, so we must choose a high-quality wire stripper. The wire stripping machine is a wire harness processing device mainly used for the protective layer of the stripping outer layer, and is widely used for automobile wire harness processing, audio wire, data wire processing, dismantling and recycling of used wires. The fully automatic wire stripper strictly cuts the wire harness. We confirmed the wiring harness according to the customer's drawing and the wire harness also complies with international standards. Then, we must first determine the length of the cutting and stripping according to the drawing and confirm that the sample and the sample meet the drawing standards. Then mass production, during the cutting process, QC carries out a sample inspection to check whether the appearance of the wire harness is worn, whether the size is qualifi

The wire is equivalent to the trunk of the human body for the wire harness. In the process of wire harness processing, the choice of wire is the most important step. If the wire is not selected at the beginning, then the finer and stricter control of the latter work will become a major failure of this product. The wire harnesses required for wire harness processing have different requirements for wire selection. The wire harnesses are applied to different environments and the harnesses have different adaptations to the surrounding environment. So how do we choose a good wire? First of all, according to the drawings provided by the customer, we can determine which type of wire the customer wants. We will then select the appropriate wire by checking the appearance of the wire, the number of bends, the temperature resistance level, the friction resistance and the corrosion resistance. When checking the number of bends, we use a rocking tester to test how many bends the wire can withs
