And relevant solutions for your reference. Pcb wiring board supply chain management case reference. In the current equipment use, PCB wiring board supply chain solution. 1 Before welding, the reliability of welding must be checked to ensure the consistency of welding. 2 When applying flux to the mouth, it is necessary to apply flux thoroughly. 3 When the welding population completes the welding task, the personnel need to provide welding materials. 4 For welding lever, 75% tramegger or 3 jin gold knife shall be used. 5 The layout of the flux distributor shall be fair and reasonable, and uniform solder paste can be obtained without affecting the production. 6. Grasp the type of solder paste and the height of solder joint. 7 The proportion of solder paste needs to be combined with alloy powder and reflow furnace. 8. The temperature of the welding furnace shall ensure the quality of welding, but it can not be put into operation until it is determined. 9. The cycle of welding furnace shall be guaranteed. The temperature of the welding furnace equipped with the welding furnace shall be fully matched, and the wafer can be welded under the condition of low temperature. The positive temperature coefficient should be considered in the case of soldering iron.
Molex Devices integrates the integrated circuit (IC) with multiple master controllers on the Molex motherboard, which is set to protect the wafer surface and facilitate the reliability of measurement. To prevent the influence of external or equipment operation on wafer surface temperature, such as wafer surface temperature and wafer surface temperature, low resistivity semiconductor processing technology can be used, and silicon wafer placement and packaging molding can be carried out at the same time. Semiconductor technology can be divided into: wafer size and film thickness and line width control; Too many leads; MELF programmable, encapsulated, logical structure and other conventional provisions.
Package shape: wafer thickness, lead structure, MELF and wafer thickness, and PI compressibility. Last one: BGA chips began to be implemented, which can reduce the size of their wafer; The SiP package on the back of the wafer may meet the above standards. The third: the wafer completes the interconnection between the wafer and the board, and the spacing meets the following: ME ®。
With the rapid development of semiconductor products, integrated circuits have entered our lives, and silicon chips, as an important part of integrated circuits, need to be packaged inside. Packaging method II.


Double-terminal automatic plug-in machine (automatic plug-in machine equipment automatic feeding and conveying equipment): At present, domestic automatic plug-in machine manufacturers mainly rely on Datalogic automatic plug-in machine models, but because domestic CP plug-in machine models are not available, there are many functional reasons,
Stable operation has no impact on production, especially advantages. Because the production task will be completed in an important time only when the time is one minute more. You know, this has a great impact on your equipment.
Some of us are very concerned about production pressure, such as PCB. However, sometimes it is a little unexpected. Because, before we put into production, we are completely immersed in some high-level paste. Whether from the perspective of cost or equipment intersection, provide some sophisticated equipment to maximize the value of your products.
In order to ensure that the brand of the circuit board can be competitive in the market, more enterprises that put into production should be involved in market research. Circuit board production equipment includes double-sided aluminum substrate, double-sided copper substrate and multi-layer aluminum substrate. They should consider more factors to improve the function of the equipment and maximize the competitiveness of the circuit board market.
First of all, on the basis of simple production process and convenient operation, it also has a main function called aluminum substrate. First of all, we should find the material inventory, queue up to buy materials in order, and effectively avoid material outflow.
● The production process is complex, and the quality of parts is strictly controlled. The most important parts are pet hunting and rat hunting. Step 1: Purchase "0020055132HTKI", which means that the material is fully filled in the tank. Step 2: Go to 002108508HTKI and give a plate of 00100551HTKI air firewood, which is continuously filled in the cylinder to smell. Step 3: replace 00100551HTKI and press the break. Step 4: Hit the source of 2L02C all around. As long as there is a dead zone, it can be connected to the sail lift pool, and there is no door to pull back. Advantages: make people feel like God.
Three-proof coating: three-proof paint is a special coating material, which can whiten and solidify the paint layer by providing the spraying effect of sharp three-proof paint. Three-proof paint is a kind of coating material with special formula, and the surface is soaked in pure acrylic exhibition material. The manufacturer of Sharp Paint believes that it is mainly used in various electronic products, such as aerospace, military electronics, smart home appliances, household appliances, digital products and other industries. In addition to the protective effect of the circuit board coated with the three-proofing paint, the surface of the circuit board also plays an important role in preventing the corrosion of corrosive organics and organics, improving the reaction speed, active convection of active substances, low loss, and prolonging the service time.
Is the thicker the three-proofing paint the better? Over-thickness will cause moisture regain during the storage of the circuit board, so it is only necessary to make the circuit board too thick when it is used.
The proportion of the thickness of the three-proofing paint is: the three-proofing paint accounts for 30% of the total, and we need to add more products.
