Experience-the shield should be designed like this!

Design guidance: (1) Shielding_frame has a flatness of 0.13mm, sufficient strength, a thickness of 0.3mm, a height of 2mm, a distance of 0.75mm from the edge of the PCB board, and the inner edge of the frame at least 0.8mm from the outer frame. (2) Shieling_cover The thickness is 0.2mm; sometimes for the heat dissipation and cooling of the components, small round holes can be added to the cover, the diameter is ￠1.0~￠1.5mm, too large will cause poor shielding effect. (3) Shielding_can shielding LCM: All matching uses 0 matching, and the distance between the side of shielding_can and the side of the LCD viewing area is greater than 1.00. Material application: Generally, the bracket can use Cu-C7521 (R-1/2H or R-OH) ( Nickel white copper, nickel silver, Nickel Silver), stainless steel, tin-plated steel strip (tinplate), etc., it is recommended to use nickel white copper. Reason: nickel silver is better in terms of welding, heat dissipation and steam. The cover is generally made of stainless steel SUS304 (R-1/2H; the shielding cover can be made of 0.1 or 0.15mm thick material, and 0.15mm should be used as much as possible; the bending type shielding bracket should be 0.20mm thick material as far as possible, and 0.15mm thick material should be used less; The tensile shielding bracket must be made of 0.2mm thick material.
