The car radar needs to be running normally when driving, and during this period, a lot of heat will be generated.
What helps dissipate heat and balance internal and external air pressure is the waterproof and breathable film covering the heat dissipation holes (ventilation holes) of electronic products.
It can also protect the inside of the product from water intrusion, and is one of the important components for protecting radar and ensuring driving safety.
Today we share aboutCar Radar Waterproof and Breathable MembraneAir tightness test case.
Our company recommends customers to use the positive and negative pressure switching test method as a waterproof and breathable membrane for automotive radarsAir tightness testingsolution.
Equipment used: Hirays HW true water seriesAir tightness detector, customized matching jigs and tooling.
Testing method: Customize the mold according to the car radar shell equipped with waterproof and breathable membrane, put the shell into the mold, and the mold fixes the shell in the designated position. After pressing the start button, the instrument enters the test program. First, the negative pressure is -10kPa, and then the test part is added with water and pressurized. The water addition time is 2s, the pressure is 30kPa, the pressurization is 5s, the pressure is stabilized for 5s, and the test is 5s. If the leakage value does not exceed 100Pa/S, it means that the waterproof and breathable membrane of the car radar is a qualified product.
