Take you to understand mobile phone shrapnel
Dongguan Precision Electronic Technology Co., Ltd. was founded in 2008. It is located by the ferry road in Shatian Town. The factory covers an area of u200bu200b6000 square meters. It specializes in the production of various precision terminals, mobile phone shrapnel, precision shrapnel, lead frames, etc., and precision metal stamping parts. Stamping parts are mainly used in electrical and electronic fields such as various mobile phones, connectors, and plugs. Mobile phone shrapnel generally have to undergo surface treatment. The general surface treatments are: gold-plated, silver-plated, nickel-plated, and zinc-plated, while mobile phone shrapnel is mostly nickel-plated. The reason for the surface treatment is that the surface texture of the bare stainless steel is uneven and the current flow is unstable. Mobile phone shrapnel currently all use circles and waist circles (or oval), the most commonly used diameters are 4mm and 5mm. There are also 2.5mm, 3mm, 4.5mm. The usual strength is 130gf, 160gf, 180gf. (gf: Gram force). According to whether there is a concave/convex point in the center of the mobile phone shrapnel, it is divided into dotted and non-dotted. The number of national standard keys for the life of mobile phone key shrapnel requires professional testing equipment for instructive testing. The general industry will use life test equipment for testing. Among them, the test of the keys and the naked test of the metal shrapnel under the key are tested. Generally, the number of tests for bare metal shrapnel/guozai film requires the manufacturer to guarantee more than one million times, the striking speed is 2-3 times per second, the striking force is 400G, the test head is flat and the diameter is 1.5MM.
