Abstract
The invention relates to the technical field of circuit boards, in particular to a circuit board of a brushless direct-current motor controller. The circuit board comprises a circuit substrate, wherein a plurality of bonding pads are evenly distributed on the circuit substrate, a plurality of positioning holes are evenly formed in the periphery of each bonding pad, each bonding pad is provided with a specially-shaped copper sheet which is matched with the bonding pad, each specially-shaped copper sheet is evenly provided with a plurality of positioning pins which correspond to the positioning holes in the periphery of the corresponding bonding pad in position, each positioning pin is inserted in the corresponding positioning hole and reversely buckled to the back side of the corresponding bonding pad, and a plurality of welding grooves are further formed in each specially-shaped copper sheet. According to the circuit board of the brushless direct-current motor controller, due to the fact that the copper sheets with the welding grooves are additionally arranged on the bonding pads, the amount of tin on the circuit substrate can be reduced, and short-circuits of a power source can be effectively avoided.
Description
Technical field
The present invention relates to the technical field of circuit board, especially a kind of circuit board of brushless direct current motor controller.
Background technology
Circuit board is one of important component part in brushless direct current motor controller, scolding tin is again one of important step in circuit board fabrication process, because tin is not easy to be connected with general material, therefore scolding tin process often need to be by braid over braid or copper strips auxiliary welding at present, in order to meet the work requirements of brushless direct current motor controller, on circuit substrate, need to design a plurality of solder joints, be on whole circuit substrate, to need large-area scolding tin, the storage of tin on circuit substrate also can be a lot, because the fusing point of tin is lower, therefore the high temperature producing after circuit board long-term work easily causes tin fusing, tin after fusing will flow string everywhere, once the tin of stream string couples together the both positive and negative polarity of power supply, will cause short circuit, finally can cause whole brushless direct current motor controller to lose efficacy.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposing in above-mentioned background technology, the invention provides a kind of circuit board of brushless direct current motor controller, by set up the copper sheet that has a plurality of weld grooves at pad place, can reduce the storage of tin on circuit substrate, effectively avoid the generation of power supply short circuit phenomenon.
The technical solution adopted for the present invention to solve the technical problems is: a kind of circuit board of brushless direct current motor controller, comprise circuit substrate, on described circuit substrate, be evenly distributed with a plurality of pads, the surrounding of each described pad evenly offers a plurality of location holes, on each pad, be provided with the special-shaped copper sheet matching with it, on every described special-shaped copper sheet, be evenly provided with the corresponding location stitch of position of positioning hole a plurality of and pad surrounding, described location stitch is inserted into the interior also left-hand thread of corresponding location hole in the back side of pad, on every special-shaped copper sheet, also offer a plurality of weld grooves.
Further specifically, on described circuit substrate, be also provided with the vertical bar shaped copper sheet that is positioned at a plurality of pads below.
The invention has the beneficial effects as follows: the circuit board of brushless direct current motor controller of the present invention, by the pad place at circuit substrate, copper sheet is set, and on copper sheet, offer a plurality of weld grooves that can scolding tin, weld groove not only can strengthen the intensity of whole copper sheet, can also be injected into the tin of less storage, even if tin is subject to the impact of high temperature, tin after fusing also can only be in weld groove flowing among a small circle, be not easy stream string outside to weld groove, just can not flow the both positive and negative polarity of going here and there to power supply yet, and then the both positive and negative polarity of the power supply phenomenon that is not easy to be short-circuited, greatly ensured the normal work of brushless direct current motor controller.

Fig. 2 is location hole and the syndeton schematic diagram of locating stitch.
In figure: 1, circuit substrate, 2, pad, 3, location hole, 4, special-shaped copper sheet, 5, location stitch, 6, weld groove, 7, vertical bar shaped copper sheet.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
The circuit board of brushless direct current motor controller as depicted in figs. 1 and 2, comprise circuit substrate 1, on circuit substrate 1, be evenly distributed with a plurality of pads 2, the surrounding of each pad 2 evenly offers a plurality of location holes 3, on each pad 2, be provided with the special-shaped copper sheet 4 matching with it, on every special-shaped copper sheet 4, be evenly provided with a plurality of location stitch 5 corresponding with location hole 3 positions of pad 2 surroundings, location stitch 5 is inserted into the interior also left-hand thread of corresponding location hole 3 in the back side of pad 2, on every special-shaped copper sheet 4, also offer a plurality of weld grooves 6, weld groove 6 not only can strengthen the intensity of whole special-shaped copper sheet 4, can also be injected into the tin of less storage, even if tin is subject to the impact of high temperature, tin after fusing also can only be in weld groove 6 flowing among a small circle, be not easy stream string to weld groove 6 outsides, just can not flow the both positive and negative polarity of going here and there to power supply yet, and then the both positive and negative polarity of the power supply phenomenon that is not easy to be short-circuited, greatly ensured the normal work of brushless direct current motor controller.
Wherein, on circuit substrate 1, be also provided with the vertical bar shaped copper sheet 7 that is positioned at a plurality of pads 2 belows, on vertical bar shaped copper sheet 7, be also provided with a plurality of location stitch 5, these location stitch 5 are inserted into the interior also left-hand thread of location hole 3 of corresponding position on circuit substrate 1 in the back side of circuit substrate 1.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
