Abstract
The utility model is suitable for the field of printed circuit boards and provides a high-density multilayer PCB (Printed Circuit Board) capable of rapidly removing scraps and preventing drill bits from being damaged. The high-density multilayer PCB is formed by scrap removal holes, specially-shaped holes and tail holes; the tail holes are linearly formed at the edge of the PCB; and the specially-shaped holes are set according to the actual reference. In the processing design of the PCB, the working states of various drill bits are detected by the tail holes; whether the drill bits are damaged or broken or not can be easily judged; the scrap removal holes are formed inside the specially-shaped holes or are crossed with the specially-shaped holes, so that the scraps can be rapidly removed and the drill bits are also prevented from being damaged to a certain extent; and if the drill bits are damaged, the drilled tail holes can be subjected to microsectioning analysis so as to detect the quality of the drill holes and improve the processing efficiency of the PCB; and in the process of machining the specially-shaped holes of the PCB, a great amount of scraps are generated and the scraps left in the drilling process are effectively removed due to the existence of the scrap removal holes, so that the production efficiency is improved and the cost is reduced.

The utility model content
The high-density multi-layered pcb board that the purpose of the utility model is that a kind of quick removal detritus is provided and prevents drilling bit breakage, easy to clean and drill bit do not damage ND problem to be intended to solve the boring detritus that exists in the production process of existing pcb board.
The utility model is achieved in that a kind of quick removal detritus and prevents the high-density multi-layered pcb board of drilling bit breakage that this pcb board comprises: anti-dandruff hole, irregularly-shaped hole, uropore;
Said anti-dandruff hole is arranged on the interior zone of said irregularly-shaped hole, and said irregularly-shaped hole is processed in the respective regions of pcb board, and said uropore is arranged on the fringe region of pcb board.
Further, said anti-dandruff hole is at least one.
Further, said anti-dandruff hole is shaped as circle.
Further, said uropore is at least two.
The diameter of the different uropores that further, are provided with on the said pcb board is different.
Further, said uropore is arranged in a linear by diameter in the pcb board destination edge.
Further, said pcb board adopts high-density multi-layered plate as substrate.
Quick removal detritus that the utility model provides and the high-density multi-layered pcb board that prevents drilling bit breakage are made up of anti-dandruff hole, irregularly-shaped hole, uropore, and uropore is arranged in a linear at the edge of pcb board; Irregularly-shaped hole is according to the setting of quoting of reality, and intersect in the inside of irregularly-shaped hole or with it in anti-dandruff hole, in the processing design of pcb board; Detect the operating state of all kinds of drill bits through uropore, can distinguish very easily whether drill bit damages or fracture, and intersect in the inside of irregularly-shaped hole or with it in anti-dandruff hole; Can faster detritus be removed, prevent the breakage of drill bit to a certain extent simultaneously, if the drilling bit breakage situation has taken place; Can cook the microsection analysis to the uropore that gets out, and then detect the quality of boring, improve the working (machining) efficiency of pcb board; Produce a lot of chips in the process of the irregularly-shaped hole of processing PCB plate, because the chip that stays because of boring is removed in the existence in anti-dandruff hole effectively; Improve production efficiency, reduced cost.
