Abstract

The utility model discloses a FPC board with small slotted hole, which comprises a plate body, the slotted hole has been seted up on the plate body, the slotted hole is the waist circle that constitutes by the drilling of a plurality of overlaps, it is bored by the drilling that the diameter is less than 0.35mm, and is a plurality of the centre of a circle of drilling is in same straight line, and the slotted hole that forms by a plurality of drilling overlap that are less than 0.35mm is offered on its surface of this FPC board, because the slotted hole is chewed by a plurality of drilling that are less than 0.35mm to can adopt the drilling that the diameter is less than 0.35mm to bore.

Description

FPC board with small slotted hole
Technical Field
The utility model relates to a flexible circuit board technical field especially relates to a FPC board with small slotted hole.
Background
Drilling a base material of the flexible circuit board, wherein the base material is generally provided with a circular hole, a groove-shaped hole and an opposite-shaped hole, and the holes are used for conducting and positioning two sides and plugging components; the machining mode of the groove-shaped hole is that the groove-shaped hole with the groove width of less than 0.35mm (inclusive) is changed from laser drilling to mechanical drilling, the mechanical drilling mode is that the base material, the bearing plate and the laminated plate are packaged and fixed to a mechanical drilling machine, a special cutter is used for drilling the base material according to preset parameters, however, the diameter of the existing special groove-shaped cutter is 0.35mm at the minimum, and the groove-shaped hole with the width of less than 0.35mm cannot be machined.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a FPC board with small slotted hole, its surface is offered by a plurality of slotted holes that are less than 0.35 mm's drilling overlap and is formed, because the slotted hole is by a plurality of drilling that are less than 0.35mm to can adopt the diameter to be less than 0.35 mm's drill bit to bore.
The purpose of the utility model is realized by adopting the following technical scheme:
the FPC board with the small slotted holes comprises a board body, wherein the board body is provided with the slotted holes, the slotted holes are in a kidney-shaped shape formed by a plurality of overlapped drilled holes, the drilled holes are formed by drilling with a drill bit with the diameter smaller than 0.35mm, and the centers of the plurality of drilled holes are positioned on the same straight line.
Further, the distance between the centers of the adjacent drill holes is less than 0.02 mm.
Further, the length of the slotted hole is 0.75mm, and the width is 0.25 mm.
Further, the diameter of the bore hole is 0.25 mm.
Further, the depth of the drilled hole is 1 mm.
Compared with the prior art, the beneficial effects of the utility model reside in that:
because the slotted hole comprises a plurality of drilled holes with intersecting bottoms in the application, the slotted hole can be formed by drilling with a drill bit, and the problem that the existing slotted hole cutter can not process slotted holes with the width smaller than 0.35mm is effectively solved.
Drawings
Fig. 1 is a schematic structural view of an FPC board with small slots according to the present invention.
The figure is as follows: 1. a plate body; 2. a slot hole.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in figure 1, the FPC board with a tiny slotted hole comprises a board body 1, a slotted hole 2 is formed in the board body 1, the slotted hole 2 is in a kidney-shaped shape formed by a plurality of overlapped drilled holes, the drilled holes are formed by drilling with a drill bit with the diameter smaller than 0.35mm, and the centers of the plurality of drilled holes are positioned on the same straight line.
Because the slotted hole 2 in this application comprises the drilling of a plurality of bottoms of meeting to make this application slotted hole 2 can utilize the drill to dash to bore and form, effectively solved the unable problem that processes the slotted hole 2 that the width is less than 0.35mm of current slotted hole 2 sword.
When the slot hole 2 of the present application is processed, the drill bit is used to drill a plurality of times at the position where the slot hole 2 needs to be opened, i.e. forming, and after forming, the drill bit is used again to repair the edge of the slot hole 2.
Preferably, the distance between the centers of adjacent holes is less than 0.02mm in this application, so as to improve the flatness of the edges of the slot 2.
Preferably, the slot 2 has a length of 0.75mm and a width of 0.25 mm.
Preferably, the diameter of the drilled hole is 0.25mm, so as to be able to make slotted holes 2 with a width greater than 0.25mm and less than 0.35 mm.
Preferably, the depth of the drilling hole is 1mm to meet the requirement of mounting components.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
