On body.
Further, described PCB layout design is using the paster copper sheet of PCB as cabling.
Further, using two-sided copper sheet, large area paster copper sheet is also adopted by the circuit at the PCB carrier back side, allows two sides
Paster copper sheet turns on to form double-sided wiring mode.
Further, described paster copper sheet big 0.5-2mm more unilateral than the nickel strap of battery.
Further, the aperture of described conducting via is 0.2-0.4mm.
Further, the aperture of described conducting via is 0.3mm.
Further, punched on corresponding two sides of described paster copper sheet, 3-5 conducting via is beaten per side.
Further, punched on four sides of described paster copper sheet, 3-5 conducting via is beaten per side.
The utility model has following technique effect：Using device described in the utility model, can be by Surface Mount component
It is firmly fixed on PCB carrier with paster pad, so as to reach the anti-dropping capability of product, improves the service life of product,
Product rejection rate is reduced, improve production efficiency reduces the functions such as product cost.
Specifically, the utility model has following significant technique effect：
1st, will not be influenceed to be separated with PCB pads by the gravity for falling using PCB trace design protection device PIN,
Cause device to be opened a way to do over again；
2nd, the connection of paster pad and PCB carrier is reinforced, product rejection rate is reduced, production cost is reduced；
3rd, the gluing process of Surface Mount component, improve production efficiency, reduction processing cost are reduced；
4th, extend product service life, improve customer experience degree and satisfaction.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of anti-drop device of Surface Mount component, including PCB carrier, it is arranged on the patch on PCB carrier
Piece pad and paster copper sheet, in the utility model, described device is using PCB layout design, the i.e. copper sheet using PCB as walking
Line, by increasing front paster copper sheet area, increases conducting via and back side cabling copper sheet is firm by component and paster pad
Be fixed on PCB carrier, so as to reach the anti-dropping capability of product, improve the service life of product, reduce product rejection rate,
Improve production efficiency, reduces the functions such as product cost.
As shown in figures 3 to 6, in the present embodiment, paster pad is the position of tin cream on PCB, for component is welded on
On PCB carrier, by the area (red area 2 shown in Fig. 3) of the copper sheet 1 around the paster pad for increasing the big device of Surface Mount, it is
Exempt from device paster hour offset, upper soldering disc area does not increase (Fig. 3 purples part 3), while being also adopted by circuit overleaf big
Area paster copper sheet 4, as shown in figure 4, (note conducting via is not using conducting via 5 mode is added around the paster copper sheet for increasing
Purple welding disking area 3 on energy, in order to avoid in tin cream access aperture, cause rosin joint), allow two sides paster copper sheet to turn on to form PCB6 double-sided cloths
Line mode, by the pad of Surface Mount component by back side paster copper sheet 4 and the dual pulling force mode in conducting via 5 face, such as Fig. 5 institutes
Show tangent plane effect, the pad of Surface Mount component is firmly fixed on the carrier of PCB6, Fig. 6 is front and back effect after processing
Fruit schematic diagram.
Paster copper sheet big 0.5-2mm mm more unilateral than the nickel strap of battery, the aperture for turning on via 5 is 0.2-0.4mm, preferably
0.3mm, it is unilateral to beat 3-5 conducting via, corresponding two sides are at least beaten, preferably make a call to four sides.In the present embodiment, mainly
It is the drag force by turning on via 5 and back side paster copper sheet 4, is device side stress when falling, the back side is by the middle of dual platen
Glass fibre shelves, have pulling force effect.By turn on via 5 draw device side copper sheet do not come off, be also by checking,
There is very big effect, conducting via 5 plays interface unit face and back side copper sheet, so the back side can rise to positive copper sheet pulling
Power.It is contemplated that two-sided stress, the copper sheet at the back side pulls positive stress across glass fibre, has played very big effect.
According to above-described embodiment as can be seen that the utility model has following technique effect：
1st, will not be influenceed to be separated with PCB pads by the gravity for falling using PCB trace design protection device PIN,
Cause device to be opened a way to do over again；
2nd, the connection of paster pad and PCB carrier is reinforced, product rejection rate is reduced, production cost is reduced；
3rd, the gluing process of Surface Mount component, improve production efficiency, reduction processing cost are reduced；
4th, extend product service life, improve customer experience degree and satisfaction.
