Electromagnetic shielding cover, what causes the unevenness of the shielding cover + stamping accuracy can reach 0.01mm

The hardware responsible for the production of electromagnetic shields said that many of my friends have encountered the problem of poor flatness of the shield. The false soldering phenomenon of the motherboard has affected the quality, efficiency, and various phenomena of customers. Xiaoshuo will analyze with you several reasons for poor flatness: 1. Reasons for mold making. The mold of the shielding cover did not meet the accuracy requirements during processing or assembly, which fundamentally caused problems. In later production, it is easy to cause undesirable phenomena. 2. Inadequate control of the quality of the production process. In the production of the shielding cover, if the raw materials are defective, it is easy to cause poor production. In addition, the mold will wear out during work. If it is not found in time, it will cause batch defects. 3. Packaging and transportation issues. Due to the unreasonable design of the tray or the unreasonable design of the carrier tape, it will be compressed and deformed after being laminated. Or in logistics and transportation, squeezing and bumping under the influence of external forces can also cause defects. Hardware, focusing on electromagnetic shielding cover for 15 years, focusing on the quality of shielding cover, starting from the design of the mold, control every tiny movement and process, and the flatness is controlled within 0.07mm in the process. There are 16 quality inspections, and the quality is strictly checked. With a daily production capacity of 3 million strokes, every customer is satisfied with quality, service, and production capacity!
