Abstract

The utility model relates to the field of PCB technology, and specially relates to an alignment monitor structure for layers of PCBs. The alignment monitor structure comprises a plurality of layers of PCBs, the edge of each PCB is provided with a plurality of aligning blocks correspondingly, the aligning blocks are extended out of the trim line of each PCB, and a plurality of aligning blocks are distributed at the side edges of two opposite corners of each PCB. According to the alignment monitor structure, each PCB is provided with aligning blocks, the alignment of each PCB is rapidly monitored, unqualified products with unqualified interlayer alignment is rapidly and accurately detected, and defective products are prevented from flowing to a client, operation of the monitor structure is simple, no extra alignment test equipment is required, and costs are reduced.

Description

Each level to level alignment degree monitoring structure of pcb board

technical field:

The utility model relates to PCB technical field, relates in particular to each level to level alignment degree monitoring structure of a kind of pcb board.

background technology:

PCB(Printed Circuit Board, printed circuit board (PCB)) be important electronic unit, be the supporter of electronic devices and components, be the supplier of electronic devices and components electrical connection.At present, along with the fast development of PCB industry, its application is also more and more extensive.Electronic equipment is little arrives greatly computer, communication electronic device, military armament systems to electronic watch, calculator, general-purpose computer, as long as there are the electronic devices and components such as integrated circuit, the electric interconnection between them all will be used PCB.At present, a lot of pcb boards are to be formed by multi-layer PCB board pressing, and pcb board is had relatively high expectations to each level to level alignment degree, and interlayer skew requires to be no more than 0.1mm.In existing PCB manufacture process, pcb board itself does not have Aligning degree monitoring structure, general employing produced 4 external Aligning degree test modules monitoring Aligning degrees of plate plate angle placement, troublesome poeration, Aligning degree is not easy to control, once test module just damage cannot effective monitoring to the Aligning degree situation of each unit in production plate.

utility model content:

The purpose of this utility model is exactly for the deficiency of prior art existence, to provide a kind of can monitor the Aligning degree between each layer of pcb board, easy to operate each level to level alignment degree monitoring structure of pcb board.

To achieve these goals, the technical solution adopted in the utility model is:

Each level to level alignment degree monitoring structure of pcb board, it includes multi-layer PCB board, and on the limit of every layer of pcb board, all correspondence is distributed with a plurality of alignment blocks.

Described alignment block extends the object line of every layer of pcb board.

At least two limits of every layer of pcb board are distributed with alignment block.

Preferably, described a plurality of alignment block is distributed in the lateral location at two angles that pcb board is relative.

Preferably, be distributed with two alignment blocks on every layer of pcb board, two alignment blocks are distributed in respectively on a side at two angles that pcb board is relative.

More preferably, on every layer of pcb board, be distributed with four alignment blocks, on the dual-side at two angles that pcb board is relative, be respectively distributed with an alignment block.

Every layer of pcb board forms alignment block by etching mode.

The utility model beneficial effect is: the utility model includes multi-layer PCB board, on the limit of every layer of pcb board, all correspondence is distributed with a plurality of alignment blocks, the utility model by arranging alignment block on every layer of pcb board, can be effectively, the Aligning degree situation between each layer of pcb board of Fast Monitoring, after completing, pcb board can find fast and accurately the defective item that level to level alignment degree exceeds standard, prevent that defective products is lost to client, this monitoring structure is simple to operation, do not need optional equipment Aligning degree testing equipment, save cost.

accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is decomposing schematic representation of the present utility model.

embodiment:

Below in conjunction with accompanying drawing, the utility model is further described, sees shown in Fig. 1 ~ 2, each level to level alignment degree monitoring structure of pcb board, it includes multi-layer PCB board 1, and on the limit of every layer of pcb board 1, all correspondence is distributed with a plurality of alignment blocks 2.

Every layer of pcb board 1 forms alignment block 2 by etching mode, and easy to process, cost is low.Alignment block 2 extends the object line 11 of every layer of pcb board 1, the copper alignment block 2 of the pcb board rear dew of the complete object line 11 of 1 milling, convenient monitoring Aligning degree.

1 at least two limit of every layer of pcb board is distributed with alignment block 2, aims at accurately.A plurality of alignment blocks 2 are distributed in the lateral location at two angles that pcb board 1 is relative, and it is convenient to aim at.Can be on every layer of pcb board 1, to be distributed with 2, two alignment blocks 2 of two alignment blocks to be distributed in respectively on a side at two angles that pcb board 1 is relative; Also can be on every layer of pcb board 1, to be distributed with four alignment blocks 2, respectively be distributed with an alignment block 2 on the dual-side at two angles that pcb board 1 is relative, it be more accurate to locate.

The utility model by arranging alignment block 2 on every layer of pcb board 1, can be effectively, the Aligning degree situation between each layer of pcb board of Fast Monitoring, after completing, pcb board 1 can find fast and accurately the defective item that level to level alignment degree exceeds standard, prevent that defective products is lost to client, this monitoring structure is simple to operation, do not need optional equipment Aligning degree testing equipment, save cost.

Certainly, the above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
