The role of electronic cleaning agent
Cleaning agents are widely used in electronic manufacturing processes, and are often used to remove potential flux, solder paste, adhesive residue, and other common contaminants such as dust and debris in the production of PCBs. Cleaning can ensure that the components have a good surface resistance, to prevent leakage caused by the failure of the PCB board to fundamentally extend the service life of the product.

The use of thermal conductive silicone grease
First, wipe with a clean cotton cloth or cotton ball. After wiping, dry the processor to ensure the surface is dry. Apply thermal paste is to first determine the size of the contact surface between the radiator base and the heat source, and apply the thermal paste with less amount.

1, room temperature vulcanized silicone rubber is characterized by the production of room temperature without heating, in a certain molding pressure base can be cured. Room temperature vulcanized silicone rubber in the production of silicone rubber products is only need to add different additives can make the rubber material has different density, hardness, strength, fluidity and thixotropy and flame retardant, conductive, thermal conductivity, burn resistance and other special properties.

Which components cannot be painted with three-proof paint?
At present, electronic manufacturers are popular to brush moisture-proof oil on the circuit board. The protection of the circuit board by the three-proof paint is warmly sought after by everyone, but it cannot blindly follow the trend, because some components on the circuit board cannot be brushed with the three-proof paint, otherwise it will cause the circuit board to be defective.

Three anti paint (three anti glue) and potting glue which waterproof better?
The criteria for judging the waterproofness of the three-proof paint and potting glue are different, the manufacturer's formula is different, and the main characteristics are also different. Three-proof paint: the paint film is transparent and can meet the properties of moisture-proof, salt spray-proof, corrosion-proof, flame-retardant, temperature-resistant, insulation, etc. It is also called circuit board protective paint, waterproof glue, electronic glue, insulating oil, etc. It is mainly used on electronic circuit boards. In the electronic industry, the circuit board is the core component. Moisture-proof oil is the circuit board that protects the circuit board from moisture, moisture, moisture, moisture, moisture, dust, metal powder, metal powder, exposed in the tin oxide, metal powder, exposed in.
