RF circuit shielding cover, what factors need to be considered when designing the shielding cover + 3 million punching next day production capacity
The technicians who produce the hardware of radio frequency circuit shielding cover said that the shielding cover applied to the motherboard of mobile phones, transformers, routers, etc., because of its thin material and high flatness requirements, so in the design of the shielding cover, consideration should be given to molds, Factors such as mass production, packaging and transportation, the following is a brief summary of the following points for your reference: 1. Material selection of the shielding cover. At present, most of the shielding frames in the market use 0.2MM/white copper, and the shielding covers use 0.1MM and 0.15MM or 0.2MM stainless steel. The shielding frame is SMT welding, and the shielding cover is buckled on the shielding frame. 2. The design of the shielding cover is mostly in a flat or small convex-concave suspension way to avoid the same product from affecting the quality and efficiency of production due to excessive high and low arcs. 3. At present, the commonly used shielding covers are divided into two kinds, one is bending and the other is stretching. If the design of your shielding cover is to choose the way of stretching, the size and width of 1.2mm or more should be reserved at the frame to ensure the mold assembly and smoothness in actual production. 4. If the size of the shielding frame is greater than 25MM, in the tape packaging, the roundness of the inner ring of the material should be increased to prevent the inner ring from being too small in the tape and deforming the shielding frame. Hardware, 15 years of focus on radio frequency circuit shielding, 20,000+ sets of customized stamping mold production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing and production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy up to 0.01 mm, the raw materials are imported and the original national standard, and 16 quality inspections are strictly controlled. Is your partner worthy of choice.
