Description
Technical field
The present invention relates to FPC wiring board techniques field, specially a kind of improved method of FPC drilling holes on circuit board inspection.
Background technology
Flexible PCB (FPC) is that have height reliability to be a kind of made of base material using polyimides or polyester film,
Excellent flexible printed circuit, it has the characteristics of high Distribution density, in light weight, thickness of thin and bending property are good, produced
During, cause yield too low in order to prevent out short-circuit excessive or reduce the thick technological problemses such as drilling, calendering and cutting and lead
The FPC plates of cause are scrapped and the problem of feed supplements, and assess how the flexible circuitry that selection can reach the optimum efficiency that client uses
Plate, antenatal pretreatment, which seems, to be even more important, it is necessary to which processing has three aspects, these three aspects are all by work for antenatal pretreatment
Whether Cheng Shi is completed, and is FPC plate engineering evaluations first, mainly assess the FPC plates of client and can produce, the production capacity of company is
The no making sheet requirement that can meet client and unit cost, if next engineering evaluation is by then needing to stock up, meeting at once
The raw material supply of each production link, finally, engineer are handled project files such as the CAD structure charts of client, with suitable
The production environment and production specification of production equipment are closed, then transfers the production data such as drawing and MI (engineering process card) to production
Each departments such as portion, text control and buying, into conventional manufacturing procedures.
By production procedure can be divided into single sided board system (sawing sheet → drilling → patch dry film → contraposition → exposure → development → etching →
Demoulding → surface treatment → paste epiphragma → compacting → solidification → surface treatment → heavy nickel gold → lettering symbol → shearing → electrical measurement →
Punching → whole inspection → packaging → shipment) and dual platen system (sawing sheet → drilling → PTH → plating → pre-treatment → patch dry film → contraposition
→ exposure → development → graphic plating → demoulding → pre-treatment → patch dry film → contraposition exposure → development → etching → demoulding → table
Face handle → paste epiphragma → compacting → solidification → heavy nickel gold → lettering symbol → shearing → electrical measurement → punching → whole inspection → packaging →
Shipment), it is widely used in mobile phone, CD walkmans and computer screen etc..
FPC drilling holes on circuit board technique in making more uses 0.1mm drill points, often because the linear measure longimetry of board drill point is inaccurate
Board also pin is caused to be alarmed, so as to cause to occur during FPC drilling holes on circuit board less porous phenomenon, and the hole on FPC wiring boards
Majority is the hole in 0.1MM apertures, and thickness of slab is no more than 0.1MM, because equipment process capability is limited when processing procedure produces, can not detect
Go out that porous FPC wiring boards, less porous and stopple etc. are bad, have a strong impact on the quality and stretch-out progress of product.

Portion is placed with control board.
2) control board is cleaned up, tiled FPC wiring boards on control board, and FPC wiring boards are fixed.
3) drilling machine is opened, FPC wiring boards are punched together with control board, control board starts small-sized as reference frame
Hair-dryer, blow burr etc. caused by drilling and accelerate drill bit radiating, the accumulation of timely cleaning operation platform.
4) acrylic board is taken out, the FPC wiring boards after punching and its control board are corresponded and are positioned in collecting box, is pressed
According to sequentially being arranged and numbered.
5) control board is put into reagent container successively and dyed, to investigate the number of punching, by number not to FPC
Wiring board, which takes out, separately to be put.
6) quadratic search is carried out to the FPC wiring boards of taking-up using checking machine, prevents that punching kicks the beam on control board, the marking is not
It is bright, caused by error, so as to divide certified products and substandard products.
(3) beneficial effect
Compared with prior art, the invention provides the improved method that a kind of FPC drilling holes on circuit board is examined, possessing following has
Beneficial effect：
1st, the improved method that the FPC drilling holes on circuit board is examined is right after FPC wiring boards by when drilling machine punches
Control board is marked, and is reacted using reagent and reactant, reactant is produced compared with dark colour, and opaque shield, which stops, to be removed
Color is shown after labeled punching, by the colored number of perforations shown on control board, by corresponding number not to FPC wiring boards
Eliminate and, the time used is investigated in saving with checking machine in turn, and quadratic search is carried out to the FPC wiring boards of taking-up using checking machine
(prevent on control board punching to kick the beam, the marking is failed to understand, caused by error), so as to divide certified products and substandard products, ensure the product of product
Matter and manufacturing schedule.
2nd, the improved method that the FPC drilling holes on circuit board is examined, produced by the way that FPC wiring boards are corresponding with control board, in time
Changed and cleared up, reduce the aggregation of drilling adhesion thing, start small blower, blown burr etc. caused by drilling and accelerate
The radiating of drill bit.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is invention control plate structure schematic diagram.
In figure：1 acrylic board, 2 control boards, 3 reactants, 4 opaque shields.
Embodiment
Below in conjunction with embodiments of the invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched
State, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on the present invention
