Elaplus Case Study on Thin Layer Sealing of Automotive Oil Pump PCB
In the wave of intelligentization in the automotive industry, electronic control systems are becoming the “nerve center” of vehicle operation. As the core execution unit of the fuel supply system, the fuel pump controller PCB has long faced extreme challenges under harsh operating conditions: high-temperature roasting at 120 ℃ in the engine compartment, gasoline vapor erosion, and continuous mechanical vibration… all of which are threatening the reliable operation of electronic components. How to build all-weather protective barriers for critical circuits? The Wave of Automotive Electronics and the Challenge of PCB EncapsulationWith the development of intelligent and electrified automobiles, electronic control systems have become the core components of modern cars. From engine management systems to battery control units for new energy vehicles, precision printed circuit boards (PCBs) work continuously in harsh environments such as high temperatures, vibrations, and humidity, and their reliability directly affects the safety and durability of the vehicle. However, the application of PCBs in key components such as automotive oil pumps faces the following challenges:Adverse environment: Complex working conditions such as high temperature, high humidity, oil pollution, and vibration require extremely high protection for electronic components.High reliability requirement: Electronic component failure may lead to oil pump failure, which in turn can cause vehicle power system paralysis or safety hazards.Environmental Protection and Regulatory Pressure: Global environmental standards for automotive components are becoming increasingly strict, and the problems of solvent residue and heavy metal pollution in traditional sealing materials urgently need to be addressed.Recommended product: PUR 1627A/B two-component polyurethane sealantPUR 1627A/B is a two-component solvent-free room temperature or heat cured resin elastomer composite used in two-component sealing, filling, flame retardant, thermal conductivity and other fields. The raw materials are free of heavy metals, environmentally friendly, and have a wide range of process operability. The finished product has high physical properties…
