Solution for Partial Encapsulation of Contactor Induction Switch

In automotive electronics, home appliance controllers, and intelligent devices, the contactor induction switch is the core induction and triggering unit. Its working environment is often accompanied by moisture, vibration, dust, and cold and hot cycles, which impose strict requirements on the protection of internal circuits. In order to further enhance the stability, durability, and protective performance of products, more and more manufacturers are adopting the “local encapsulation inside the shell” scheme to achieve long-term sealing protection of sensitive circuit boards (PCBs) and sensing areas.Today, we introduce to you a widely used and highly stable fast curing epoxy adhesive in the industry – EP 2005 fast curing epoxy adhesiveIt is particularly suitable for this scenario:✔ PA66+30% fiberglass shell✔ Partial sealing protection✔…

Epoxy sealant | Oil pressure sensor packaging

Oil pressure sensors are usually installed in the engine lubrication system and are exposed to high temperatures, strong vibrations, oil and fuel vapors for a long time. They also need to withstand harsh working conditions such as cold and hot shocks, refrigerant immersion, salt spray, and humid heat.Therefore, materials used for packaging electronic components inside sensors must meet the following key performance requirements:Excellent oil resistance and chemical stabilityCan resist long-term erosion from fully synthetic engine oil, mineral engine oil, transmission fluid, gasoline vapor, and common refrigerants.Wide temperature adaptation rangeThe engine compartment environment temperature fluctuates greatly, requiring materials to have long-term temperature resistance of -40 ℃ to 150 ℃ and be able to withstand transient high temperatures of the engine.Reliable mechanical…

Solution for Sealing the Collision Sensor Shell and Bonding the Circuit Board

With the widespread adoption of active safety systems in automobiles, crash sensors have become an indispensable key component in the overall vehicle safety system. Collision sensors are usually installed on the front, longitudinal beams, or side structures, with extremely high requirements for signal stability, environmental adaptability, and structural strength. In its internal structure, the sealing of the shell, the bonding and fixation of the circuit board, and the overall sealing protection are directly related to the stability of the sensor in high temperature, vibration, humidity, and impact environments. Therefore, it is crucial to choose appropriate potting adhesive, sealant, and circuit board bonding materials.In response to the typical application requirements of collision sensors, Yilian has launched three high reliability materials:PUR 1680,…

Solution for sealing the internal coil of car door handles

With the popularity of keyless entry systems (PEPS) in new energy and high-end fuel vehicles, door handles have been upgraded from traditional mechanical handles to intelligent components that integrate coils, micro switches, and antenna modules.These sensing coils are responsible for implementing key functions such as touch recognition, proximity sensing, and vehicle owner authentication, and their stability directly determines user experience and vehicle safety. Due to the long-term exposure of the door handle to the outdoors, its internal antenna coil needs to face:The damp heat cycle caused by long-term exposure to sunlight and rainCold and hot shock under temperature difference between winter and summer (-40~125 ℃)Structural fatigue caused by frequent pullingDifficulty in sealing due to narrow cavities and complex structuresTherefore, the…

Science Popularization of Thermal Conductive Epoxy Structural Adhesive | Principles, Characteristics, and Engineering Application System Analysis

01 | What is thermal conductive epoxy structural adhesive?Thermally Conductive Epoxy Structural Adhesive is a high-performance adhesive material that uses epoxy resin as the matrix, adds high thermal conductivity fillers, and forms a dense three-dimensional network structure through crosslinking reactions with curing agents. Its material essentially consists of three types of properties: ① Structural StrengthHigh shear strength, high peel strengthAnti impact, anti vibration, anti fatigueDimensional stability for long-term serviceIt can replace traditional mechanical fixing methods such as screwing, riveting, and welding.② Thermal ConductivityThermal conductive fillers (such as Al ₂ O3, BN, AlN) form a continuous thermal conduction chain during the curing process, giving the material significantly higher thermal conductivity than ordinary epoxy.This function is used for heat transfer of heating…
