Circuit board flame retardant rubber is a material used to protect circuit boards and other electronic components, and has flame retardant properties. Here is some information about flame retardant rubber for circuit boards:

1. Flame retardant performance: Flame retardant rubber for circuit substrates usually adopts a special flame retardant formula, which can inhibit combustion and reduce the risk of fire when exposed to external heat sources such as flames. The material usually complies with international flame retardant standards, such as UL94 V-0 rating.

2. Insulation performance: The flame retardant rubber of the circuit substrate has good insulation performance, which can effectively protect the electronic components from the influence of electrical faults and other factors.

3. Heat resistance: Flame retardant rubber for circuit substrates usually has certain high temperature resistance, which can maintain the stability and performance of the material within a certain temperature range.

4. Adhesion performance: Flame retardant rubber for circuit substrates is often used to fill and seal the gaps or cracks of electronic components, which has good adhesion performance and can ensure the fixation and sealing of electronic components.

5. Environmental performance: Modern circuit substrate flame retardant rubber is usually made of environmentally friendly materials, does not contain harmful substances, and meets relevant environmental protection regulations and standards.

6. Precautions for use: When selecting and using flame retardant rubber for circuit substrates, it should be selected according to specific application needs and requirements. At the same time, follow the instructions and recommendations provided by the material manufacturer to ensure proper use and safe operation.

Special effects for electronic and electrical adhesives

1. Conductive adhesive: Conductive adhesive has good electrical conductivity and is used to connect conductive components, repair conductive lines or provide reliable grounding. Common conductive adhesive materials include silver glue, copper glue, conductive silicone, etc.

2. Insulating glue: Insulating glue is suitable for situations that require electrical insulation and mechanical fixing, such as fixing electronic components, preventing electrical short circuits and sealing of insulating parts. Insulating adhesives are usually non-conductive, such as epoxy adhesives, silicone gels, etc.

3. Structural adhesive: Structural adhesive is used to provide strength and support, and is often used to fix electronic devices, connect circuit boards and protect components. Common structural adhesive materials include epoxy resin glue, acrylic glue, etc.

4. Thermal conductivity adhesive: Thermal conductivity adhesive is mainly used for heat dissipation, which can improve the heat dissipation effect of electronic equipment. Thermal adhesives usually have high thermal conductivity, such as silica-based thermal conductivity adhesives, conductive silicone grease, etc.

5. Adhesive gasket: Adhesive gasket is used to fill and balance uneven surfaces between electronic devices, providing better connection strength and sealing. Common types of bonded gaskets include silicone gaskets, polyester membrane gaskets, etc.

When using flame retardant rubber for circuit boards, the following matters need to be noted:

1. Material selection: According to the specific application environment and requirements, select the flame retardant rubber material of the circuit substrate that meets the relevant standards and specifications. Ensure that the flame retardant properties of the material and other performance indicators meet expectations.

2. Temperature limit: understand the temperature range of the flame retardant rubber of the circuit board, and ensure that it is used within the specified temperature range to avoid the degradation or deformation of material properties caused by over-temperature.

3. Application mode: According to the specific use needs, choose the appropriate application method, such as injection molding, coating or filling, etc. At the same time, ensure the correct construction technology and conditions to ensure excellent finished product quality.

4. Compatibility: When using flame retardant rubber for circuit substrates, it is necessary to consider the facultative properties with other materials. In particular, compatibility with electronic components, substrates, and other sealing materials to avoid adverse reactions or damage.

5. Construction environment: ensure that the construction is carried out under suitable environmental conditions to avoid the impact of dust, humidity or other pollutants on the construction performance of the material. At the same time, pay attention to protective measures to avoid harm to your health.

6. Storage and safekeeping: Properly store and keep the flame retardant rubber of the circuit substrate, and avoid contact with humidity, direct sunlight or other harmful substances. Manage the shelf life and storage conditions of the material in accordance with the recommendations provided by the manufacturer.

7. Safe operation: When using circuit-based flame retardant rubber, follow the safety operation procedures and wear necessary personal protective equipment, such as gloves and safety glasses. Avoid direct contact with skin and eyes, and avoid inhaling or accidentally ingesting materials.
