Abstract
The utility model relates to a multilayer PCB plate possessing a quality inspection ring, and especially relates to each layer sheet material structure. The invention has the purpose that the multilayer PCB plate possessing the quality inspection ring with convenient processing and sheet material quality enhancement is provided. The multilayer PCB plate possessing the quality inspection ring has an internal layer taken as a core plate, an upper layer and a lower layer, an insulating layer is provided between the internal layer and the upper layer as well as the lower layer, concentric circular rings which enable mutual cooperation are provided on the opposed faces of the internal layer and the upper layer, and the concentric circular rings which enable mutual cooperation are provided on the opposed faces of the internal layer and the lower layer. The multilayer PCB plate possessing the quality inspection ring has the advantages that the concentric circular rings alignment capacity in the internal layer can substantially increase the precision of alignment, and the short circuit caused by internal layer dislocation is reduced.
Description
Technical field
The utility model relates to multi-layer PCB board, relates to especially its each laminate equipment structure.
Background technology
Pcb board is exactly 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 consists of substrate, the tiny line material that can see on the surface is 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 webbed tiny circuit.These circuits are known as wire or claim wiring, and are used to provide the circuit connection of part on the pcb board.
The precision of the contraposition of the existing wayward interior interlayer of multi-layer PCB board, easily cause the off normal of internal layer, occur in the production process of back that internal layer is opened, short circuit, since in open, short can not the repairing, can only beat and scrap, greatly improved production cost, and in open, shortly badly when looking for, be difficult for being found, easily flow to client, affect the functional of product, cause client to use.
The utility model content
The purpose of this utility model provide a kind of easy to process, be beneficial to the multi-layer PCB board with quality testing ring that improves board quality.
The technical scheme that realizes the utility model purpose is as follows:
A kind of multi-layer PCB board with quality testing ring, have internal layer, the upper and lower as central layer, be provided with insulating barrier between above-mentioned internal layer and the upper and lower layer, above-mentioned internal layer and upper strata opposite face are provided with the donut of working in coordination, and internal layer and lower floor's opposite face are provided with the donut of working in coordination.
Above-mentioned donut be distributed in pcb board around, the spacing of donut is 3～5mil.
This novel benefit is that at first internal layer improves the precision of contraposition greatly to potential energy with donut, reduces the short circuit that the internal layer dislocation causes, cost can be effectively saved in short generation in having controlled from the source; Secondly whether pcb board multilayer is made and can be detected very easily multiple-plate interior interlayer off normal amount whether in scope with X-ray afterwards, can judge in advance product and meet the requirements, and has reduced rear operation and has tested, looks for workload a little, avoids defective products to flow to client.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, this novel multi-layer PCB board with quality testing ring has internal layer 1, upper strata 31 and the lower floor 32 as central layer, be provided with insulating barrier 2 between above-mentioned internal layer and the upper and lower layer, above-mentioned internal layer and upper strata opposite face are provided with the donut of working in coordination, and internal layer and lower floor's opposite face are provided with the donut of working in coordination.When the processing PCB multi-layer sheet, aim at compoundly by the donut of working in coordination, can guarantee machining accuracy, the present embodiment is 4 layers of pcb board, if insulating barrier and circuit layer on compound more respectively in upper strata, lower floor then become 6 layers of pcb board.
For convenient aligning and detection, above-mentioned donut be distributed in pcb board around, the spacing of donut is 3～5mil, above-mentioned mil is mil, is mil, the spacing of donut can be according to the structural adjustment of product.
Obviously, above-mentioned embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy on the basis of the above description make other pro forma variation or alternative, and these changes or alternative also will being included within the definite protection range of the utility model.
Claims (2)
1. multi-layer PCB board with quality testing ring, have internal layer (1), upper strata (31) and lower floor (32) as central layer, be provided with insulating barrier (2) between above-mentioned internal layer and the upper and lower layer, it is characterized in that: above-mentioned internal layer and upper strata opposite face are provided with the donut of working in coordination, and internal layer and lower floor's opposite face are provided with the donut of working in coordination.
2. the multi-layer PCB board with quality testing ring according to claim 1 is characterized in that: above-mentioned donut be distributed in pcb board around, the spacing of donut is 3～5mil.
