LAP was developed by tontop to deal with these characteristics of LDS. LAP has the same stereoscopic properties as LDS, but it does not need special laser-induced materials, and the cost of plastic materials is saved by 50%~70%. In the actual mass production process, under the same defect rate, the cost of high-priced modified materials lost by LDS process will be much higher than that of LAP, especially the middle frame or shell antenna. Moreover, it can be completely realized by domestic laser equipment, with excellent performance and price, completely independent intellectual property rights, and is not affected by LDS overseas patents. Basically suitable for all common plastic substrates, including PC, PC/ABS, ABS, glass, ceramics and so on. Moreover, because the ordinary substrate does not need to add modified materials, antenna debugging will not be affected by dielectric constant, which is more conducive to antenna debugging design.
