Abstract
The utility model relates to a PCB board, in particular to a weld disc structure thereof. The utility model aims to provide a PCB board weld disc with a tin pulling structure which has low cost and reliable performance. The PCB board weld disc with a tin pulling structure is provided with weld points for welding, wherein the weld points extend to form a tin pulling strip which is in a narrow strip shape whose weld point end is thick, and tail end is thin. The PCB board weld disc has the prominent characteristics that after the tin pulling strip is extended, the welding operation can be carried out on the tin pulling strip, as the tin pulling strip is in a narrow strip, and the space between the tail ends is larger, the problem of bridge connection short-circuit of the weld points is greatly reduced, thereby further improving the manufacture ability of PCB board products, and being beneficial for increasing the circuit integration of the PCB board products.
Description
Technical field
The utility model relates to pcb board, relates to its pad structure especially.
Background technology
Pcb board is exactly a printed circuit board (PCB), almost can appear in the middle of each electronic equipment.And electronic component just is set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.This plate is heat insulation by insulation, also unbending material constitutes substrate, the tiny line material that can see on the surface is a Copper Foil, originally Copper Foil is to cover on the whole plank, and part is etched in manufacture process disposes, and the part that stays has just become netted tiny circuit.These circuits are known as lead or claim wiring, and are used to provide the circuit connection of part on the pcb board.The welding circle design of existing pcb board all is an annulus, adopt between the pad without hindrance every design, adjacent two solder joints are easy to form bridging when welding, are unfavorable for improving the integrated level of solder joint.
The utility model content
The purpose of this utility model provides a kind of pcb board pad that drags the tin structure that has of with low cost, dependable performance.
The technical scheme that realizes the utility model purpose is as follows:
A kind of have a pcb board pad that drags the tin structure, has the solder joint that is used for welding, and above-mentioned solder joint extends out to form and drags tin bar.The above-mentioned tin bar that drags is the long and narrow bar shaped that the solder joint end is thick, tail end is thin.Outstanding feature of the present utility model be from solder joint extend drag tin bar after, can carry out welding operation on the tin bar dragging, owing to drag tin bar to be narrow, bigger in space, tail end place, thereby significantly reduced the bridging short circuit problem of solder joint, and then promoted the making ability of pcb board product, help improving the circuit integrated level of pcb board product.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, solid matter is provided with conductivity solder joint 1 on the utility model pcb board pad, extends outward from solder joint and drags tin bar 2, above-mentionedly drags that tin bar is thick at the solder joint place, the tail end place is thinner.When carrying out welding operation, weld at the tail end that drags tin bar and to be not easy to take place solder joint bridging phenomenon, reduced the short circuit problem of solder joint like this, can improve the circuit integrated level of pcb board simultaneously.
Claims (2)
1. one kind has the pcb board pad that drags the tin structure, has the solder joint (1) that is used for welding, and it is characterized in that: above-mentioned solder joint extends out to form and drags tin bar (2).
2. according to claim 1 have a pcb board pad that drags the tin structure, and it is characterized in that: the above-mentioned tin bar that drags is the long and narrow bar shaped that the solder joint end is thick, tail end is thin.
