From the characteristic evaluation of electronic parts, semiconductor devices and materials, the price trend of raw materials for pcb installation connectors. Accumulated capital to serve the cause.
This week, the frequency song "Urban Strategy" on the East China e-commerce offline exchange conference (338979) pointed out that from passive parts to automotive devices, to semiconductor materials, pharmaceutical products, liquid air, biological bubbles, hot air, gases, and chemical products, these fields continue to do a good job in OEM, effectively reducing supply chain risks.

● Automatic control is set when upgrading according to the program provided by the manufacturer. Since each factory of the manufacturer has its own control panel, the working machines are relatively redundant. The control boards used by a machine are basically integrated, so the embedded control boards are basically integrated, and the sockets used on the circuit boards provided by the manufacturer can also be used. One programmable set-top box is inserted here, and the other sockets are integrated, so the working machine is relatively easy to use.
Working principle of the circuit board: evenly arrange the power socket on the printed board, and then use the socket to place the copper foil of the circuit board on the copper clad foil with the left hand, and exchange it along the direction of the tolerance of the components until the thickness of the copper foil, so as to fully connect with the division of the reverse copper foil.
The capacity of the junction capacitor cannot exceed 5 million. If you want to improve the current effect, you can add a large capacity resistor on the capacitor.
Improving the production efficiency of the placement machine can enhance the production efficiency of our placement machine. The problem of "labor production" can be solved by using a lower placement machine. Improving the production efficiency can support higher costs.
Because we pay more attention to the existing placement machine architecture, the technology is updated with new production lines and systems, and the productivity is higher, which can improve the production efficiency, or change the original set standards, so as to improve the efficiency of the production line. The new production line and system structure will make the new production line and production line form a complete, cost-effective production line. At present, the capacity will build a platform in the system of the new production line. The new production line will not slow down the production process and achieve high economic efficiency. Moreover, the new production line and system structure will make the production system on the production line smaller and more reasonable.
The importance of the design department will enable new production lines (such as BIM porter, HR) to reliably implement quality requirements and maximize production efficiency.
Hardware engineers provide numerous combinations for all internal hardware engineers on the production line, from simple and light circuit boards to complex multilayer circuit boards and flexible hardware modules. Every industry can route normal flow production. No matter what internal circuit board design engineers, they can provide reliable and efficient solutions.
Two layers of chemical corrosion are used to form and detect the front and back sides of the surface of the object to be tested. After geometric comparison treatment, the wire can be made. The FR4 layer process can be made according to the needs, and the permanent guide etching can be made. Three-layer chemical etching is used to form a three-dimensional model, and standard samples are used for etching process, without heavy metal coating and heavy metal. Three-layer chemical corrosion was used to form a three-dimensional model, and the three-dimensional model was subjected to acid.
Compared with the traditional three-proofing paint, solvent is environmentally friendly, pollution-free and solvent-free, which can improve the environmental pollution, significantly improve the process performance, and improve the space. It is good for the device to bear small torque and wear resistance.

The metal three-proofing paint is mainly used to protect the circuit board and its related equipment from various chemical attacks, extend the service life of the product, but at the same time, it will aggravate the deformation of the components, so it must be controlled here. There are many control methods, such as spraying, brushing, dipping, drenching, etc. The following will introduce the process of various kinds of three-proofing coatings and precautions for use: 1. When measuring various types of temperatures, the three-proofing coating must be measured. The temperature shall be measured according to the actual data of the three-proofing coating. The requirements and standards of different devices are different. 2. Please find a regular manufacturer of three-proofing paint for inquiry. 2. The components of IC coating glue can be cleaned by solvent cleaning and adhesion, and then use the website of Evimi.
SIPC has the function of antenna and twisted-pair. It closely contacts the two adhesive tapes, and the unsaturated adhesive rubber tapes are bonded to each other. The adhesive force will cause the accumulated heat to be transferred to the back, affecting the tension and tension.
