Abstract

The utility model discloses a support multiple dress welding and power supply mode's small-size wireless communication module, including the PCB board, be equipped with the contact pin hole on the PCB board, the edge of PCB board still is equipped with the stamp hole, the utility model discloses can solve the shortcoming that single encapsulation mode brought, stamp hole and two kinds of mounting means of contact pin exist simultaneously. The user selects a welding mode suitable for the user according to different requirements. For the mainboard with large space and small heat productivity, the stamp hole mode can be adopted for patch welding. For the mainboard with larger heat generation, such as a ball bulb, the welding pin mode can be adopted for assembly. The power supply method is applicable to a motherboard capable of providing 3.3V or 5V.

Description

Small wireless communication module supporting multiple welding and power supply modes

Technical Field

The utility model relates to a PCB technical field specifically is a support multiple dress welding and power supply mode's small-size wireless communication module.

Background

The conventional wireless communication module has the packaging modes of LGA, stamp hole, pin and the like. The LGA mode pad is arranged on the bottom surface of the module, can only be installed through a chip mounter, cannot guarantee the welding yield, and is difficult to disassemble. The stamp hole mode has the pad at the module bottom surface, also has semi-circular trompil at the module side, both can install through the chip mounter, can carry out manual welding through the side trompil again, convenient operation, and the welding yield obtains guaranteeing. The pin style has a circular receptacle on the module and the mating pin is soldered to the base plate, but only manually. The power supply is only single 3.3V or 5V, and only 2 can select one.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a support multiple dress welding and power supply mode's small-size wireless communication module to solve the problem that provides in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the small-sized wireless communication module supporting various welding and power supply modes comprises a PCB, wherein a pin hole is formed in the PCB, and a stamp hole is formed in the edge of the PCB.

As the preferred scheme of the utility model: 23 pin holes and 23 stamp holes are formed in the stamp.

As the preferred scheme of the utility model: the PCB, the pin hole and the stamp hole are integrally formed.

As the preferred scheme of the utility model: and two power supply input ends are arranged on the PCB.

As the preferred scheme of the utility model: the power input terminals include a 5V power input terminal and a 3.3V power input terminal.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can solve the shortcoming that single encapsulation mode brought, stamp hole and two kinds of mounting means of contact pin exist simultaneously. The user selects a welding mode suitable for the user according to different requirements. For the mainboard with large space and small heat productivity, the stamp hole mode can be adopted for patch welding. For the mainboard with larger heat generation, such as a ball bulb, the welding pin mode can be adopted for assembly. The power supply method is applicable to a motherboard capable of providing 3.3V or 5V.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, embodiment 1: the embodiment of the utility model provides an in, a support multiple dress welding and power supply mode's small-size wireless communication module, including PCB board 1, be equipped with pin hole 3 on PCB board 1, PCB board 1's edge still is equipped with stamp hole 2, just so solves the shortcoming that single encapsulation mode brought, and stamp hole 2 and 3 two kinds of mounting means of pin hole coexist, both can connect other PCB boards through stamp hole 2, can install other electronic component through pin hole 3 again, and the user selects the welding mode that is fit for oneself according to the demand of difference. For the mainboard with large space and small heat productivity, the stamp hole 2 mode can be adopted for patch welding. For the mainboard with larger heat generation, such as a ball bulb, the welding pin mode can be adopted for assembly.

Example 2: on the basis of embodiment 1, the PCB of the present design is provided with two power input terminals, including a 5V power input terminal and a 3.3V power input terminal, as shown in a Pin diagram in fig. 2, for a product that the main board can provide a 3.3V power, the product can be directly connected to Pin17 for power supply; the mainboard only has a 5V power supply interface and can be directly connected with Pin 19. Convenient and flexible

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
