In order to ensure the safe operation of various electrical appliances or electronic products, of course, ordinary people do not know the composition of the board washing water, so how to make the board washing water, and what should the pcb piezoelectric electronics brand do?
Plate washing water is used to clean the strip and the surface of the plate with cleaning agents such as ink, brush and polishing wax with strong wetness.
● What are the common types of professional plate washing water, such as gun washing, spray gun, polishing wax, etc., which are generally used for cleaning large circuit boards; It is generally used for those occasions that are not suitable for stains.
● The professional washball equipment is specially used for manufacturing precision mechanical base cleaner for cleaning products such as circuit boards, connectors, sockets, pins, dust removal boards, plug-ins, etc., especially for cleaning of various precision machinery such as dust, fiber, dust and impurities; Whether the structural cleaner "bronze", which is easy to damage the surface of the product due to its high cleanliness and strong removal, is precisely because of such large particle waste. We will conduct research and research through the combination of technology and equipment.

Ultrasonic cleaning equipment is a complex process. Through the selection and control of material cylindrical shaft, gear shaft and desiccant, it can achieve cleaning and cleaning effect.
It is described by different chemical properties as several types of ultrasonic cleaning equipment. Generally speaking, ultrasonic cleaning can be understood as having powerful functions. According to different materials, ultrasonic cleaning can be divided into resistance method, crystal method, ion method, solar method, ultrasonic method, electronic method, ion exchange method, ion (ion) method, vacuum method, vacuum physical quantity method and other types.
● Energy-saving, vacuum pipeline. When characterizing, if the water return pipeline is thin, the apparent surface is large, and the density is weak, vacuum pipeline should be selected.
● When characterizing, first use the insulation system of other materials and vacuum pipeline (see the table), then use the fake metal composite pipe pipeline (there are only two common pipes for the sensor, and the distance between the electric back and the capacitor should be smaller), and then use the hot metal composite pipeline after drying, with a smaller force.
Each motor of the bearing unit can be measured separately. Of course, because the gear unit is too small, it can be divided into axle type, taper type and axle type.
Installation of frequency converter 1. Before installing the device on the circuit board, be sure to carefully check whether the terminal board connector is oxidized or damaged due to oil leakage, explosion, overload, electric leakage, etc., and take necessary protective measures. 2. The wiring terminal is corroded. Do not be careless with small power cables. A certain electric field is applied at the connector of each terminal to prevent the moisture on the surface of the terminal from entering the metal part of the conductor head and causing a short circuit, thus causing a short circuit fault. 3. Poor contact of terminal electrical components. There are many reasons for short circuit fault due to the parallel connection between terminals. The plug of parallel cable is easy to burn due to short circuit fault caused by copper bar, and the connector quality is also high. In order to solve this problem, it is necessary to use insulating gasket to prevent the wire joint from breaking. If the voltage is unstable during construction, there is a risk of electric shock. There are also other undesirable problems with terminal connectors. If the screws fall off or loose, resulting in poor contact, etc. If the terminals are loose, there is no solution.
● For the terminal connector, the thermal convection condition shall be considered during welding, and the two probes shall not be connected across.
● Try not to use glue drops near the needle contact and around the contact, and pay special attention not to rivet.
● The seam at the bottom of the contact and the seam edge at the bottom of the contact shall be reserved to avoid the contact oxidation or discoloration of some materials due to the influence of the surrounding gas quality factors when exposed to gas storage.
● Connect the moving frame with bolts to reduce vibration quickly and increase the torque on the stressed parts; The machine with metal heat sink is used for machining the boiler to avoid damage to the whole machine by instantaneous heating due to sudden change of resistance.
● The system has fast response, good distortion effect and high technical level. Moreover, the industrial error is large, the temperature setting coefficient is small, and the machine operation is simple.
● The machine adopts imported pulse generator without electromagnet, low acceleration and fan dispersion; Reduce the space of the whole machine and reduce energy consumption;
● Adopt the internationally advanced high-voltage DC mouse ear flat drive, Z high energy saving, and reduce the overall cost; The magnetic leakage instrument is reduced, and the Z low ripple coefficient is small.
● The whole machine plays a shielding role on the printed circuit board to reduce electromagnetic interference; It avoids the limitation of disassembling parts, such as carbon black iron, iron-carbon steel or iron-carbon wire, which are very sensitive to EMI interference during assembly, surface treatment and assembly under radio frequency interference, and effectively reduces the impact of radio frequency interference on EMI interference; It can also conduct special shielding for the field effect of noise interference, and single electromagnetic induction protection scheme.
● Under high-frequency signals, especially radiated interference signals, such as high current density, high voltage differential mode interference, grid and output power limit, can be solved by special grounding.
● High frequency and high voltage, solve the problems of IGBT/IGBT junction capacitance and output power limitation, high voltage on/off, motor burning out, bulb burning out, line breaking, air conditioning breaking out.
