Abstract

The invention discloses a printed circuit board, a mobile terminal, a mobile terminal shielding frame and a preparation method therefor, and aims to solve the problem that the shielding frame in the prior art cannot shield interference signals of a mobile phone main board CPU and a power supply. For fulfilling the purpose, the invention provides the mobile terminal shielding frame, wherein side walls are arranged around the mobile terminal shielding frame; the side walls form welding legs; and the welding pins are provided with outwardly-bent bending legs.

Description

technical field [0001] The invention relates to the field, in particular to a printed circuit board, a mobile terminal, a shielding frame of the mobile terminal and a preparation method. Background technique [0002] The motherboard CPU and power supply of the mobile terminal have many interference signals, and the shielding frame is required to block the interference signals, so as to increase the ability of the mobile phone to receive 2G 3G 4G signals. [0003] At present, the shielding frame in the prior art is often unable to shield the interference signals from the CPU and power supply of the mainboard of the mobile phone, which affects the ability of the mobile phone to receive 2G 3G 4G signals. Contents of the invention [0004] One of the reasons for the above defects is that the solderable area of ​​the shielding frame of the mobile terminal is small, resulting in poor welding between the shielding frame and the printed circuit board; [0005] In view of the reas...
