Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0047] In order to improve the effective layout space of the LGA module, the antenna can first be connected to the RF pad on the bottom board through the wiring on the printed circuit board of the bottom board, and connected to the RF pad of the LGA module through the RF pad on the bottom board, thereby realizing Interconnection of the antenna to the LGA module. The LGA module and the backplane may also be provided with pads for transmitting non-radio ...

Abstract

The embodiments of the invention bring forward an electronic device and a grid array LGA module. The electronic device comprises a first printed circuit board, a base plate and an antenna, wherein the lower surface of the first printed circuit board is provided with a first radiofrequency pad and a first non-radiofrequency pad; the base plate comprises a second printed circuit board; the upper surface of the second printed circuit board is provided with a second radiofrequency pad and a second non-radiofrequency pad; the first radiofrequency pad and the second radiofrequency pad are connected; the first non-radiofrequency pad and the second non-radiofrequency pad are connected; the antenna is disposed on the base plate and is connected with the second radiofrequency pad; the size of the first radiofrequency pad is smaller than the size of the first non-radiofrequency pad; the size of the second radiofrequency pad is smaller than the size of the second non-radiofrequency pad; and the first radiofrequency pad and the second radiofrequency pad are used for transmitting radiofrequency signals transmitted by the antenna between an LGA module and the base plate. Since the radiofrequency pad of the LGA module does not occupy the space at the top surface of the LGA module, the effective layout space of the LGA module is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a grid array module. Background technique [0002] Land Grid Array (LGA) modules are more and more widely used in communication, vehicle, consumer electronics and other special fields. The LGA module has complete functions, for example, the LGA module usually has functions such as wireless reception, signal processing and wireless transmission. The LGA module includes a printed circuit board (Printed Circuit Broad, PCB) and pads. Due to the high wiring density of the LGA module, its printed circuit board usually adopts a high density interconnect (High Density Interconnect, HDI) printed circuit board. HDI printed circuit boards have thinner dielectrics, smaller dimensions, and allow for smaller device pitches. [0003] The antenna connected to the LGA module generally includes a main antenna, a secondary antenna, a Global Position System (Global Po...
