1. Anti-collision and anti-collision: If we say that the obvious advantage of the cob package display is the protection ability. The COB packaged LED display inherits all the advantages of the SMD packaged LED display, cob led display，and there is no trouble of light failure.
2. Ultra-small dot pitch: The production process of the COB package display screen is simplified, there is no lamp-making process, there is less physical separation between the light-emitting chips, and the display screen is fuller and richer.
3. "Surface" light source light: SMD package led display has the characteristics of point light. The COB display itself is a surface light source, which can effectively suppress moire fringes and provide a better viewing experience.
4. Strong heat dissipation and good quality: the heat generated by the cob-packaged display screen during use can be dissipated directly through the PCB board, the heat does not accumulate, and the product life is more guaranteed.

Although industrial endoscopes are widely used in the industrial field, many consumers do not understand what it really means. Endoscope can also be called endoscope. It is a multi-disciplinary general tool that can deeply detect parts that cannot be directly seen by the naked eye,camera module， and can observe the internal space structure and state in the sealed cavity, so it can realize long-distance observation. and operation.
The endoscopes used in the industrial field are industrial endoscopes. Endoscopy is actually the use of industrial endoscopes DIOUS containers, pipes, the inside of equipment that cannot be disassembled, the inner surfaces of narrow gaps, and the human vision below the solution level. Methods for quality control and visual inspection in special environments that cannot be directly observed.
In the past, it was mainly used for the control of residual materials in aerospace products and the quality inspection of some parts. Today's industrial endoscopes have entered the practical stage, and more and more good industrial endoscopes are used earlier in different productions. process.

1. Do not twist the strap after it is hardened. Replace the strap in time if it hardens.
2. It is recommended that consumers wear belts only in winter. Sweat easily in summer or after exercise. If you can't wear it, band for watch , you shouldn't wear it. If you really want to wear it, you should wipe off the sweat before wearing it, which can prolong the life of the leather strap. .
3. There are many materials for the belt, no matter which material is worn for a long time, it will produce odor, so cleaning and keeping it dry is the only way to maintain the belt
4. The belt watch should not be worn from time to time. If there are more than two watches, it is best to replace them. The leather needs to breathe, and a ventilated environment can prolong the life of the strap. Wearing different straps can not only reduce the risk of injury to the human body, but also allow the straps to get enough rest.

The key link of plastic processing. Forming various forms of plastics (powders, granules, solutions or dispersions) into products or blanks in the desired shape.
The choice depends mainly on the type of plastic (thermoplastic or thermoset),plastic manufacturing ， the initial form, and the shape and size of the product.
Common methods for plastics processing thermoplastics include extrusion, injection molding, calendering, blow molding, and thermoforming. Plastics Processing Thermosets are generally molded, transfer molded, and injection molded. Lamination, forming and thermoforming are the forming of plastics on a flat surface.

Exercise your child's balance and coordination
Kids can also ride a scooter, but parents need to help him in the back. Riding a scooter requires a certain balance ability,best kick scooter， which can exercise children's balance ability and physical coordination ability particularly well.
exercise leg strength
The scooter mainly relies on one foot to push and slide forward. This action can exercise leg strength very well, and it can also play a good role in children learning other sports.

①High-safety vehicles bring a sense of security to passengers. Multiple safety measures for various safety components fully ensure the safety of passengers.
② Quiet and smooth traction drive is relatively quiet.home lift， The permanent magnet synchronous host has no reduction box and no gear friction mechanical sound. As long as the installation and debugging are in place, the operation is very smooth.
③Long service life Due to the use of counterweight to balance the car, the movable pulley structure makes the service life of the elevator more than twice that of other platforms.
④Energy saving and environmental protection Permanent magnet synchronous main engine does not need regular oil change, and there is no possibility of oil leakage.

1. Performance of anti-static plastic: When the same material or other similar materials rub or separate from each other, plastic products ， it has the least charged material.
2. Performance of conductive plastic: It is a functional polymer material, which is mixed with resin and conductive material and processed like plastic.
Different application fields
1. Anti-static plastic application fields: semiconductor equipment and microelectronic equipment, electrical and electronic, medicine and food, precision instruments and biotechnology, etc.
2. Application fields of conductive plastics: Mainly used in electronics, integrated circuit packaging, electromagnetic wave shielding and other fields.

Electric remote control model car referred to as EP
The electric remote control model car, as the name suggests, is powered by the accelerator,rc company， outputting electric energy to the motor, and the motor drives the car.
Electric remote control model cars are the first choice for many beginners, because they can be charged as long as there is "electricity", a fully charged battery can drive the car to walk, the inertia of the tram is small, and the control skills are easy to master.
Oil-powered remote control model car referred to as GP
The oil-powered remote control model car is the incarnation of Pengpai power. The oil car uses the special fuel for the remote control model car. Most oil trucks use a two-stroke air-cooled engine, which has the advantages of fast acceleration and convenient maintenance.
Tanker trucks are becoming more and more popular. Even for beginners, choosing to buy a gas truck is a good choice. Now the maintenance of the oil car is relatively simple, and the oil car has a long competition time, which can better improve the driving skills and accumulate more experience. !

condenser microphone
Advantages: Delicate and full sound quality, high definition, speaker microphone bluetooth， high sensitivity, suitable for recording studio environment.
Disadvantages: Afraid of getting wet, afraid of falling, too high sensitivity, easy to absorb noise and vocal glitches.
Dynamic microphone
Advantages: strong anti-noise ability, soft and full sound quality, suitable for noisy environments and stage performances.
Disadvantages: low volume, dull vocals, poor clarity, poor sensitivity
Everything has two sides. In a noisy environment, if there is no high requirement for sound quality, a dynamic microphone is the first choice. Condenser microphones are the right choice for scenarios that require professional recording or clear sound quality.
