Having dock some front conducting strip that printed circuit board (PCB) welds together with described positioned at its front end upper surface is horizontal arranged
(101), the upper surface projection formation of the docking printed circuit board (PCB) and some upper terminals of butt connector (201), the printing electricity
The terminal that the projection of docking printed circuit board (PCB) upper surface is formed in the board component of road is relatively thin, and resistance value is smaller, transmits signal stabilization,
Switching printed circuit board (PCB) simultaneously in printed circuit-board assembly, docking printed circuit board (PCB) are welded, and overall structure is simple, it is easy to
Manufacture.
Chinese patent CN103037619A discloses a kind of printed circuit-board assembly can be by using chip conduct itself
Printed circuit board (PCB) and electronic component is installed with wafer scale, the printed circuit-board assembly includes：Multiple electronic components；Printing electricity
Road plate, the plurality of electronic component are installed on the printed circuit board；Protective, is configured to the printing electricity is completely covered
Road plate；Connection unit, one end of the connection unit are exposed to the outside of protective, and the printed circuit board (PCB) is electrically connected to
Daughter board, wherein, the printed circuit board (PCB) includes the chip printed circuit board (PCB) formed by chip.
The easy rosin joint of existing printed circuit-board assembly or solder skip, cause yield rate not high.
Utility model content
The purpose of this utility model is to provide a kind of anti-rosin joint printed circuit-board assembly, the printing that this utility model is provided
Circuit board assemblies can prevent printed circuit board (PCB) rosin joint.
For achieving the above object, this utility model provides a kind of anti-rosin joint printed circuit-board assembly, the anti-rosin joint printing
Circuit board assemblies include printed circuit board (PCB) body, are located at the spot area in the printed circuit board (PCB) body front, the solder joint area
Domain is provided with the perforation from thickness direction through the printed circuit board (PCB) body.
Preferably, the anti-rosin joint printed circuit-board assembly also includes detecting that device, the detection device include chassis, position
Two binding posts in the LED of the charged below the chassis and above the chassis, described two binding posts point
Do not electrically connect with the both positive and negative polarity of the LED, the binding post can be penetrated in the perforation.
Preferably, the perforation is formed as front aperture greatly, and reverse side aperture is little.
Preferably, the perforation is formed as tubaeform or truncated cone-shaped.
This utility model has the advantage that：
This utility model arranges perforation in the spot area of printed circuit board (PCB) body, can make scolding tin in electric welding by wearing
Hole stream arrives the printed circuit board (PCB) body back side, so as to pass through naked eyes detection solder joint whether rosin joint or dry joint, and reinforces solder joint area simultaneously
The weld strength in domain；In addition, the further detection of solder joint for convenience, can arrange detection device, so as to further detect be
No solder skip or rosin joint.For convenience at solder joint scolding tin flowing, perforation can be up big and down small, be rendered as tubaeform or round platform
Shape.
Description of the drawings
Fig. 1 is a kind of structural representation of specific embodiment of this utility model printed circuit-board assembly.
Fig. 2 is a kind of structural representation of specific embodiment of this utility model perforation.
Fig. 3 is a kind of structural representation of specific embodiment of this utility model detection device.
Specific embodiment
Detailed description below is used for this utility model to be described, but is not limited to scope of the present utility model.
As shown in figure 1, this utility model provides a kind of anti-rosin joint printed circuit-board assembly, the anti-rosin joint printed circuit board (PCB)
Component includes printed circuit board (PCB) body 1, is located at the spot area 2 in 1 front of printed circuit board (PCB) body, the spot area 2
It is provided with the perforation 3 through the printed circuit board (PCB) body 1 from thickness direction.
This utility model arranges perforation in the spot area of printed circuit board (PCB) body, can make scolding tin in electric welding by wearing
Hole stream arrives the printed circuit board (PCB) body back side, so as to pass through naked eyes detection solder joint whether rosin joint or dry joint, and reinforces solder joint area simultaneously
The weld strength in domain.
As shown in figure 3, the further detection of solder joint for convenience, can arrange detection device, so as to further detect be
No solder skip or rosin joint, the detection device include chassis 4, the LED 6 of the charged being located at below the chassis 4 and are located at institute
Two binding posts 5 above chassis 4 are stated, described two binding posts are electrically connected with the both positive and negative polarity of the LED 6 respectively, described connect
Terminal 5 can be penetrated in the perforation 3.
As shown in Fig. 2 for convenience at solder joint scolding tin flowing, it is big that the perforation 3 can be formed as front aperture, reverse side
Aperture is little.For example, the perforation 3 is formed as tubaeform or truncated cone-shaped.
Although, above make detailed description to this utility model with general explanation and specific embodiment,
But on the basis of this utility model, it can be made some modifications or improvements, this is aobvious and easy to those skilled in the art
See.Therefore, these modifications or improvements on the basis of without departing from this utility model spirit, belong to this utility model
Claimed scope.
