Embodiment Construction

[0024] The specific implementation of the circuit board design for preventing the 180-degree reverse attachment of the antenna shrapnel provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Please refer to image 3 , is a schematic diagram of a circuit board according to a specific embodiment of the present invention.

[0026] The circuit board includes: a base plate 308; an outer frame line 301 located on the surface of the base plate 308; a pad 302 located on the surface of the base plate 308 within the outer frame line 301; a surface of the base plate 308 located on at least one side of the outer frame line 301 The identification pattern 303 is used to identify the welding position between the pad 302 and the object to be welded.

[0027] The area inside the outer frame line 301 is the area where the solder is located after being soldered to the circuit board. The object to be soldered includes a solderin...

Abstract

The invention discloses a circuit board. The circuit board comprises a baseplate, an outer frame line arranged on the surface of the baseplate, a bonding pad arranged on the surface of the baseplate in the outer frame line, and a marking graph arranged on the surface of the baseplate on at least one side of the outer frame line and used for marking a welding position of the bonding pad and a to-be-welded object. According to the design of the circuit board, 180-degree reverse adhesion and misplacement of antenna elastic sheets can be prevented, the problems of no mobile phone signal and the like which are caused by a failure to use the antenna elastic sheets normally are avoided, the error rate and the rework cost are reduced, and the production cycle is shortened.

Description

technical field [0001] The invention relates to the field of circuit board design, in particular to a circuit board and a welding structure. Background technique [0002] The antenna shrapnel is used to transmit and receive signals in the mobile phone. When it is soldered to the circuit board, its welding area should correspond to the pad of the circuit board. [0003] In the prior art, the circuit board of the antenna shrapnel only includes pads and outer frame lines, so it is difficult to identify the welding direction and corresponding position during welding, which may easily cause the antenna shrapnel to be 180-degree reversed and position deviation, and the antenna shrapnel cannot be normal. The function of the mobile phone will lead to problems such as no signal of the mobile phone, which will eventually increase the cost of rework and prolong the production cycle. [0004] Please refer to figure 1 and figure 2 The antenna shrapnel in the prior art includes a weld...
