RF module shielding cover, what are the technical requirements for the production of the shielding cover + the stamping surface is as smooth as jade

The hardware of the manufacturer that manufactures the shielding cover of the radio frequency module said, what are the requirements when producing the shielding cover of the circuit board, the following Xiaoshuo based on 15 years of experience in the design and production of the shielding cover, let everyone know what are the requirements for the production of the shielding cover: Generally, stainless steel is used for bending processing, deep drawing, and tin-plated steel with tinplate. The main products are radio frequency shielding parts, baseband shielding covers, SIM card holders, LCD frames and other precision mobile phone accessories, as well as hardware stamping, automatic lathes, springs and other accessories used in electronic products and medical machinery. The shielding cover is required to be free of oil, no front, no scratches, no deformation, and the stamping tolerance is within 0.1MM. The size of the reclaiming point of the shielding cover should be appropriate, and the reclaiming point should be in the middle of the material as far as possible. The size of the reclaiming point is Φ6. 0mm, the larger the reclaiming point, the higher the inconsistency of the patch and the higher the efficiency. The tray where the shielding cover is placed has too much flow space, and it is easy to swing during placement, resulting in inability to absorb. The material needs to be placed in the tray. There is a flow space of about 1.0MM. If it is too large, the material will swing. If the material is too small, the material may not be taken. Come up. Our company's mobile phone shielding covers mainly use 0.2MM nickel silver and stainless steel stamping, the product size is accurate, the flatness is good, the tinning is easy, the shielding function is good, the assembly is easy, firm, and the quality is excellent. Hardware, 15 years of focusing on radio frequency module shielding, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing 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 factory, and 16 quality inspections are strictly controlled.
