Abstract

The invention provides a mobile phone antenna made of general resin and a manufacturing technology thereof. The general resin is taken as an antenna material and the antenna material is used for manufacturing a bottom layer. The mobile phone antenna comprises a palladium layer, copper layers, a nickel layer and the palladium layer which are arranged in sequence from the bottom to the top. The general resin is a non-conductor, so electroless plating cannot be carried out. After the non-conductor is preprocessed, the non-conductor is converted into a conductor and then the electroless plating can be carried out. Compared with other materials, the general resin has the advantages of miniaturization and thinning. Development of antennas of popular electronic appliances and electronic devices in the market is enabled to be more advantageous. According to the mobile phone antenna and the manufacturing technology thereof, the problems of high cost and high deficiency existing in the existing manufacturing technology for a built-in antenna of a radio communication device are improved. The general resin easy to shape is used for manufacturing the antenna, so the manufacturing cost is reduced, a development cycle is shortened and the production efficiency is improved. Compared with other materials, the general resin has the advantages of miniaturization and thinning. The development of the antennas of the popular electronic appliances and electronic devices in the market is enabled to be more advantageous.

Description

Technical field [0001] The invention belongs to the field of radio communication, and particularly relates to a manufacturing process of a built-in antenna of radio communication equipment. Background technique [0002] The existing manufacturing methods for mobile phone antennas are two-color injection molding process and LDS process. The two-color injection molding process requires two sets of injection molds, so the defective rate is relatively high, which leads to problems such as low output and production efficiency. The LDS process requires the use of very expensive laser engraving equipment and LDS special resin materials, so the production cost is very high, and it is difficult to achieve difficult shapes, resulting in many defective products. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a manufacturing process of a mobile phone antenna that can be electrolessly plated on general resin. The technical solu...
