The advantages of selective etching processing for communication electronic products

The communication electronics we come into contact with are mainly mobile phones, headphones and other market fields with high trends. The product life cycle is short, the market speed is relatively fast, and many models, small batches, short and fast have become the fighting field for major manufacturers. The product precision requires micron tolerance, and the traditional manufacturing process can't meet the demand, so etching has become the protagonist's processing method.

Which communication electronic products are involved in etching? IC lead frame, sealed ceramic cover, encoder code wheel, copier charging grid, dust-proof net, insect-proof net for smoke alarm, contact piece, spring piece, instrument board, components of wiper carriage, brush carrier accessories, handset net, FPC reinforced steel sheet, mobile phone midplane, base station components, transceiver, amplifier, antenna and micro antenna, and shielding cover for electromagnetic interference/radio frequency interference.

All of the above are processed by etching, and they all have remarkable characteristics, that is, the thickness is between 0.01MM-2MM and 2 mm, high precision and micron tolerance, the sample production of etched communication electronic products can be completed within 24 hours, the cost of mass production is low, and the benefits are high. There is a high commercial trend for developing short, flat and fast products, and they can stand out in the changing market more quickly.
