I. Recognize tin whisker Tin whisker is a common phenomenon in electronic products and devices. A whisker is a hair-like crystal that grows naturally from a solid surface, also known as an “intrinsic whisker”. Whiskers grow on many metals, most commonly on tin, cadmium, zinc, antimony and indium. Tin whiskers are tin crystals that grow naturally on the surface of tin, a phenomenon that causes problems for manufacturers who prefer to use tin rather than lead for interconnects. II. The “tin whiskers” hazard of electric vehicle recalls in china The reason stated in the bulletin is that the tinned terminals on the DC bus capacitor of the inverter which are linked to the screws of the copper rows may be short-circuited due to tin whiskers which may cause the positive and negative poles of the high-voltage DC current, resulting in no high-voltage power supply to the inverter. According to the introduction of tin whiskers in the first paragraph, we can roughly know the harm of tin whi ………………………………
