The birth and development of FPC and PCB have led to the development of new products of soft and hard combination boards. Therefore, soft and hard combination boards, that is, flexible circuit boards and hard circuit boards, are combined together according to relevant process requirements after pressing and other processes to form circuit boards with FPC characteristics and PCB characteristics.

Because the hard-flex board is a combination of FPC and PCB, the production of hard-flex board should have both FPC production equipment and PCB production equipment. First, the electronic engineer draws the circuit and shape of the soft bond board according to the requirements, and then the CAM engineer performs relevant processing and planning and sends it to the factory that can produce hard-flex board. File, then arrange the FPC production line to produce FPC, and the PCB production line to produce PCB. These two soft boards and hard boards come out, and according to the planning requirements of the electronic engineer, the FPC and PCB are seamlessly pressed together by the pressing machine, and then after a series of detailed links, the hard-flex board is finally made.

Since epoxy resins contain active epoxy groups in their molecular structure, they can react with various types of curing agents to form infusible polymers with a three-dimensional network structure. Therefore, epoxy resin adhesives or epoxy resin coatings are difficult to remove after curing. For products processed with epoxy, when they need to be reprocessed or recycled, the epoxy resin adhesive layer or coating must be removed without damage. In order to meet the market demand for such products, Rongbang has launched a highly efficient and environmentally friendly epoxy resin curing agent remover product.

Product Usage

Used to remove epoxy resin, phenolic resin, acrylic resin, 502 instant glue, polybutadiene, melamine and other polymer-based coatings and epoxy resin glue, bonding, potting and curing parts. And defective products in high-voltage electrostatic epoxy powder spraying. Such as refrigerators, washing machines, electric fans, various household appliances hanging parts, hangers, racks, various sizes of product parts repair. This product only reacts chemically with glue, but special components and equipment are excluded. Please use it with caution. After removal, it will not deform various metals and can maintain the original finish. It is the most ideal product for removing high-voltage electrostatic powder coatings.

Instructions

1. Immersion type: Simple and convenient operation: Pour the agent into a sealed container to prevent volatilization. Immerse the parts that need to remove the adhesive potting and coating completely in the remover and seal with the cover. Due to the different thickness of the coating and adhesive potting, the time depends on the thickness and quality of the glue. Observe regularly and shake frequently to speed up the dissolution rate. The coating and adhesive potting glue will be automatically removed. Rinse with water after removal.

2. Covering method: Use cotton to absorb the degumming agent and place it on the surface of the glue to be degummed, then cover it with a layer of plastic cloth, and then cover the surface with a wet towel to prevent evaporation. Repeat the operation.

3. After using this agent, you can use a filter to filter out the removed resin and it can be used repeatedly.

Precautions

1. This agent is solvent-based, volatile and irritating to the skin. To avoid inhalation and contact with the skin, ventilation should be performed and protective gloves and masks should be worn during operation. An exhaust fan should be used indoors, and outdoor operation should be selected.

2. This agent will dissolve most plastics, please use it selectively.

3. If it accidentally comes into contact with your skin, wash it immediately with plenty of water and soap. See a doctor if you feel any discomfort.

4. Because this agent is volatile, the shaking and collision during transportation will cause a large amount of gas to accumulate in the can. Therefore, please unscrew the bottle cap slowly when opening it to allow the gas to overflow slowly to avoid splashing on your body and causing unnecessary damage.

5. Observe the dissolution process in time to prevent damage to other components. Note: Be careful when dissolving important components. If any adverse consequences are caused, you will be responsible for them.

Packaging and storage

1kg 5kg 10kg 25kg. Store in a cool place, shelf life 2 years.

Application Areas

Product Usage:

The product has excellent performance in combination with PCB board. The product has very good molding characteristics and can form a certain height on the 3528 light strip. It is mainly used for glue dripping on bare boards of LED soft light strips, and can also be used for glue dripping on half-tube LED soft light strips.

Operation Notes:

1. Prepare the glue, mix according to the weight ratio of 4:1, and stir it thoroughly with a stirring device (make sure the two components are mixed evenly). Note: the stirring rod and container cannot touch other glue!
2. Vacuum. Since the molecular tension of silicone is small, bubbles inside are easily accumulated when vacuuming, and a large number of bubbles can be seen being discharged violently. So in order to avoid the waste of glue, try to deflate the air at the vent valve as many times as possible when vacuuming.
3. After eliminating the bubbles, the glue can be transferred to the professional potting equipment for drip irrigation.
4. After the glue is dripped, leave it until the glue is completely cured before proceeding to the next process.

5. Glue application environment: Organic silica gel is cured at room temperature, mainly based on temperature and humidity. That is, the higher the temperature and the greater the humidity, the faster the glue cures, and vice versa. It is generally required that the temperature of the construction workshop be controlled between 25-30 degrees and the humidity be controlled between 65-70%.

Storage and packaging: 

The product should be stored in a cool and dry place, 25 kg/set, and the lids of packaging barrels A and B should be sealed and stored immediately after opening.

Application Areas

Features:

A transformer is an electrical device that is mainly used to achieve voltage conversion and power transmission. The working principle of the transformer is based on the law of electromagnetic induction, and the voltage conversion between the input and output ends is achieved through the change of the magnetic field. The following are some basic knowledge and characteristics about transformers:

1. Working principle: The transformer consists of two or more coils (called primary coils and secondary coils) and an iron core. When AC voltage is input to the primary coil, the magnetic field generated will induce the secondary coil, and current will be generated in the secondary coil, realizing voltage conversion and power transmission.

2. Voltage conversion: The transformer can increase or decrease the voltage. The voltage at the output is inversely proportional to the voltage at the input. Through the appropriate ratio of the number of turns of the coil, the conversion between different voltage levels can be achieved.

3. Power transmission: Transformers play the role of power transmission in the power grid. Electric energy is transmitted from power plants to users through transformers, providing power supply at different voltage levels.

4. Safety isolation: The transformer has an insulated iron core between the primary coil and the secondary coil as a safety isolation, which can effectively prevent direct connection between circuits and improve the safety of the electrical system.

5. Energy saving: The working principle of the transformer is based on electromagnetic induction, which can effectively reduce resistance loss, improve energy utilization efficiency and save energy.

6. Stability and reliability: The transformer has a simple structure, stable and reliable operation, and a long service life. It is one of the important equipment in the power system.

7. Various types: According to different uses and structural forms, transformers can be divided into distribution transformers, rectifier transformers, special transformers and other types to meet the needs of different fields.

 1. Structure

A three-phase transformer is generally composed of three independent single-phase transformers, in which the primary winding and secondary winding of each transformer are connected to the three-phase power supply and the load respectively. Through proper connection and adjustment, the voltage step-up and step-down conversion between the three-phase power supply and the load can be achieved.

2. Working Principle

The working principle of a three-phase transformer is basically the same as that of a single-phase transformer, except that the phase relationship is taken into account when processing the voltage in a three-phase power system. When the voltage of the three-phase power supply is applied to the primary winding, the secondary winding induces a corresponding voltage through magnetic coupling, thereby achieving the rise and fall conversion of the three-phase voltage.

3. Type
