Problems solved by technology

[0003] The existing method of processing slits is mainly to use short-wavelength lasers such as green light to etch the metal substrate layer by layer. This method has low processing efficiency and cannot process thick slits due to the problem of depth of focus. The metal base material (up to 0.4mm), the processed product has low strength
In addition, this method requires repeated processing many times to cut through the substrate. The high-speed scanning of the galvanometer that controls the laser path has a certain accuracy. Repeated processing many times will result in a reduction in processing accuracy and an extension of processing time.

Abstract

The invention discloses a metal shell of communication equipment, which comprises a metal base material, more than one slit penetrating through the metal base material, a plastic supporting layer formed on the inner surface of the metal base material, and a The decorative layer on the outer surface of the metal substrate is characterized in that the width of the slit on the outer surface of the metal substrate is 15-500 μm, and the width of the slit on the inner surface of the metal substrate is The width is 20-600 μm, and the ratio of the width of the slit on the inner surface of the metal substrate to the width of the slit on the outer surface of the metal substrate is 1.05-1.5:1. According to the present invention, it is possible to provide a metal casing of a communication device with a smaller slit taper, which is more conducive to the passage of electromagnetic signals, and has an integrated effect in appearance.

Description

technical field [0001] The invention relates to a metal casing of communication equipment. Background technique [0002] With the development of metal processing technology, mobile communication devices such as mobile phones and tablet computers are increasingly inclined to use metal casings, especially large-area metal casings, but electromagnetic waves cannot penetrate metals. In order to achieve good electrical signal effects, metal casings are used. It is necessary to process single or multiple slits on the shell, and design the antenna at the slit. [0003] The existing method of processing slits is mainly to use short-wavelength lasers such as green light to etch the metal substrate layer by layer. This method has low processing efficiency and cannot process thick slits due to the problem of depth of focus. The metal base material (up to 0.4mm), the processed product has low strength. In addition, this method requires repeated processing many times to cut through the...
