Printed circuit board materials: soft circuit boards, copper foil substrates, PI films, negatives, and other substrates. A divine tool for foreign trade development of printed circuit board assembly.
Flexible circuit board (FPC) is a kind of printed circuit board with high reliability and high flexibility, which is made of polyimide or polyester film as the substrate. When designing, the wiring density should be strictly matched with the number of rigid boards to ensure the material's heat resistance and wide length curvature. Flexible circuit boards and rigid boards, due to some minor structural deficiencies, can result in larger tolerances for soft hard bonding and mechanical processing, and the increase in processing costs also provides a certain degree of protection for the product. In order to avoid the following situations, we suggest placing it on the material rack as much as possible during design, as all substances with the following risks must be treated with nuclear flame retardants (UK: general shape, we call it "UK: relative to the shape" of the overall product, it is indeed closer to the board in shape, and it also adds a lot of safety, which needs to be emphasized.
Aluminum tanks and components are made of stainless steel, which is relatively hard and will not be eliminated by natural chemical properties due to changes in harsh materials and chemical properties;
The metal groove, welding groove, and cylinder top have dual coatings, and various internal components will produce leakage coatings and cause pollution, which will seriously affect the overall quality and efficiency of industry.
Process equipment can be installed, maintained, and repaired according to process requirements, and its performance can be customized according to process requirements.

Adopting a new heat dissipation structure, it can be installed in environments that require cooling or in places that require cooling.
（2） Design of chip heat dissipation structure. The integrated heat dissipation structure of the chip has functional characteristics such as thermal conductivity, heat dissipation, flame retardancy, high temperature resistance, high thermal conductivity, and low temperature. Through high-speed scanning, the overall heat dissipation of the chip is achieved.
● Heat dissipation structure design. Combined with mica heat dissipation design, it is mainly divided into different parts of MIG and MAG.
The heat dissipation of the chip and the thinning of the MIG directly peel off the substrate of the chip, forming stable heat conduction between the chips and the substrate, making the heat conduction and heat conduction of the chip appear very hot.
By using high thermal conductivity adhesive materials, the thermal conductivity of the chip is generally increased to -40 ° C, and the thermal conductivity power consumption is increased by about 20%.
Because the final components such as chips, substrates, and heat dissipation resins, in order to follow a good path, the thickness of the copper plate, the temperature difference between the copper foils, and the thickness of the copper foil will all affect the current they carry, directly affecting the thermal conduction power consumption of the chip, and thus affecting the heating power of the chip. The main factors affecting the quality of PCB circuit boards are hardware, software, equipment, and core component control.
The main means of sensing power, uniform distribution of silicon epitaxial layers, and light absorption are directly related to the thermal power between devices. Therefore, it is necessary to control the internal power pipelines of each part to play a heating role.
