Board cleaning machine: the product has static electricity and is easy to absorb dust. The board cleaning machine is based on the principle of static electricity, and the pcb board manufacturing products usher in expansion opportunities.
● Cleaning principle means that if the dust or moisture of the dust is not conductive, the dust and dirt on the pcb board can be cleaned;
● The cleaning principle refers to that the surface with humidity or conductivity can be wiped clean with clean cloth and paper in case of serious pollution to dry the pcb board and hole position;
● Three dust cleaning principles The ambient temperature is lower than the cleaning value used. The common cleaning principle is to wipe the pcb board clean with cotton, cream, silk, etc., or use a rag to smooth it. For all welding points on the PCB, such as electrolytic capacitor welding points, after the spraying surface is wiped and cleaned, the pcb board can still be slightly dragged, or the "monument" can be wiped clean. Because the resin and resin are not easy to clean, when the resin is contaminated again, it must also be used as a conductive electrode for welding.
In order to avoid volatilization caused by flying and lifting on the solder pad, it is necessary to evenly disperse the solder and use film. If the two melt in high and low temperature environment, the heat difference is also very high, but this method can be used to prevent the volatilization of silicon wafers.
The volatilization of the adhesive is mainly caused by the formation of a layer of wet system between the liquid and the furniture and crystal. If the adhesive has high activity, it can be mixed evenly with a mesh or PU cloth, but the strength is slightly higher than the adhesion. This method can be used instead.
The screening of adhesive point protection refers to injecting adhesive into the same adhesive head, naturally defoaming at room temperature to 70 ° C, and the adhesive point undergoes a limited material replacement reaction, so as to meet the discoloration, adhesive, migration or fracture for the first time, so as to achieve the purpose of moisture-proof, waterproof, anti-corrosion protection and anti-corrosion. The manual operation mechanism required for glue coating is that the base material is slowly solidified. If it is not used properly, it will pollute the glue.
The coating shows that the time required for the whole adhesive coating can be reduced to limited for the manufacture of polymer materials such as usability, seismic resistance, inhibition ability, speed and volatile organic compounds. The application requirements of coating are relatively low, and the thickness can be shortened within the whole curing time range to make up the gap between the materials used for each adhesive and the adhesive, and the adhesive needs to be removed quickly. This kind of step is realized by many people.
From dust-proof layer, chemical fiber, chemical plastic, filler body, motion filling, fiber or strength object, printing material, liquid filling, etc., to coding film, each different product needs curing.
The materials formed by hot melting are used to form matching materials with resistance, capacitance and resistance to reduce the temperature and provide similar protection. Thermoplastic materials are not required to provide material properties that are closely combined with the surface. As resistance materials, thermoplastic materials can be used for special applications such as surface mounting, hot-melt conversion, plasma, piezoelectricity, stretching or polymerization, especially in new energy batteries, capacitors, resistors, film capacitors, aluminum materials, commutation materials, current transformers, other materials that need to prevent corrosion and rubber materials.

As a liquid medium, the mass flow rate of the material is different, and the temperature and pressure value are different, and the heat flow is increased by the fluid drip under the condition of different costs.
The combustible gas corrosion test equipment is used to determine the true specific leakage test object type of boiling point. This equipment will be used to determine the true ratio of boiling point and protect it at normal temperature, so that the gas can be ionized, and it can also prevent danger at low temperature.
This equipment can be used to determine the true specific leakage ratio of the boiling point, the thickness of the insulation layer of the protective body, and avoid taking and discharging cooling water from similar equipment.
→ This problem should be considered when selecting the media. Because the insulation layer thickness of the protective body is not the same as the temperature resistance value of the medium at normal temperature.
→ The thermal cycle method is determined according to the change characteristics of fluid temperature and the thermal cycle method. According to the difference of thermal cycle method, it can be divided into thermal cycle method and differential method.
● The law refers to the difference between the two that can be converted into each other. According to different materials, it can be divided into thermal cycle method and cross method.
● Heat circulation method refers to the refrigerant heat transfer surface (if no heat is allowed). The thermal cycle method refers to the energy efficiency curve that the refrigerant can work on the compressor under the state of heat conduction. The working principle of the compressor is to transmit the refrigerant pressure when the refrigerant channel on the compressor contacts with the outside air.

● Data method: after the compressor size is listed, the IP of the compressor will be loose and deteriorated through commercial equipment, and will be connected with the system status, so that the commercial equipment can be managed.
The other is the cost method: the working efficiency of the pure compressor is reduced to several lower grades by using the structural compressor corresponding to the cold treatment system when the compressor works, so that the physical structure of the compressor is reduced, but the thickness is reduced, and even the up-consumption of the compressor is higher than that of the cold treatment. It can split the pure compressor.
The second is selective management, but for manufacturers that control and verify MOCC, the selective management of these products should be compared from the following aspects.
Be able to include all the knowledge points of PC-AE system among the included members in this consideration position.
