Abstract
The utility model discloses a kind of wiring board facilitating stable segmentation, be placed in the assembly on wiring board, be placed in the cut-off rule on wiring board, be located at the hollow-out parts that cut-off rule is other.The utility model provides a kind of application stress dispersion principle, in line of cut other design hollow-out parts, thus dispersive stress, the wiring board facilitating stable segmentation avoiding assembly to damage, effectively can guarantee wiring board segmentation yield and reliability, and improve the reliability of welding stability and product.
Description
Technical field
A kind of wiring board, particularly a kind of wiring board facilitating stable segmentation.
Background technology
V-CUT is exactly V-arrangement cutting, one cutter goes down and plank is not cut, the position same at the plank back side is not also cut in partial application, the place of cutting is upper and lower two V-arrangements from cross section, only have centre in succession, if so as long as two-sided V-CUT effect one is broken exactly gently, pcb board will disconnect, generally be used for doing jigsaw or add technique edges, breaking disconnected when dispatching from the factory after having pasted chip.Need during cutting first to draw cut-off rule, cut-off rule of the prior art is damaged by the excessive assembly that causes of stress due to component design when a point off line causes point plate; Prior art is unresolved such problem also.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is that the utility model provides a kind of application stress dispersion principle, in line of cut other design hollow-out parts, thus dispersive stress, the wiring board facilitating stable segmentation avoiding assembly to damage.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Facilitate the wiring board of stable segmentation, be placed in the assembly on wiring board, be placed in the cut-off rule on wiring board, be located at the hollow-out parts that cut-off rule is other.
The aforesaid wiring board facilitating stable segmentation, the width of hollow-out parts is 2mm.
The aforesaid wiring board facilitating stable segmentation, the beeline of hollow-out parts and cut-off rule is 0.5mm.
The aforesaid wiring board facilitating stable segmentation, hollow-out parts is parallel to cut-off rule.
The aforesaid wiring board facilitating stable segmentation, the end of hollow-out parts is 14mm to the maximum distance of the end of assembly.
The aforesaid wiring board facilitating stable segmentation, hollow-out parts is perpendicular to cut-off rule.
The aforesaid wiring board facilitating stable segmentation, the end of hollow-out parts is 3mm to the maximum distance of the end of assembly.
Usefulness of the present utility model is: the utility model provides a kind of application stress dispersion principle, in line of cut other design hollow-out parts, thus dispersive stress, the wiring board facilitating stable segmentation avoiding assembly to damage, effectively can guarantee wiring board segmentation yield and reliability, and improve the reliability of welding stability and product.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of embodiment of the utility model hollow-out parts when being parallel to cut-off rule;
Fig. 2 is the front view of the utility model hollow-out parts perpendicular to a kind of embodiment during cut-off rule;
The implication of Reference numeral in figure:
The width of a hollow-out parts, the end of b hollow-out parts to the maximum distance of the end of assembly, the beeline of c hollow-out parts and cut-off rule, v-cut cut-off rule.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Facilitate the wiring board of stable segmentation, be placed in the assembly on wiring board, be placed in the cut-off rule on wiring board, be located at the hollow-out parts that cut-off rule is other.
In order to dispersive stress that can be optimum, the specification of hollow-out parts the following is optimum: the width of hollow-out parts is 2mm; The beeline of hollow-out parts and cut-off rule is 0.5mm.When hollow-out parts is parallel to cut-off rule, the end of hollow-out parts is 14mm to the maximum distance of the end of assembly; When hollow-out parts is perpendicular to cut-off rule, the end of hollow-out parts is 3mm to the maximum distance of the end of assembly.
When distance between assembly and cut-off rule is less than 5mm, assembly the most easily damages; In cut-off rule other increase hollow-out parts, can stress dispersion be applied, avoid the damage of assembly; The utility model provides a kind of application stress dispersion principle, in line of cut other design hollow-out parts, thus dispersive stress, the wiring board facilitating stable segmentation avoiding assembly to damage, effectively can guarantee wiring board segmentation yield and reliability, and improve the reliability of welding stability and product.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection range of the present utility model.
