Description
Technical field
The present invention relates to printed circuit board field, more particularly to a kind of printed circuit board repair method and system.
Background technology
The circuit of traditional printed circuit board makes, and is that one layer of photosensitive dry film or wet film are covered in plate face first, then by phenanthrene
Figure on woods is aligned in plate face, by way of exposure, line pattern is transferred in plate face, finally using chemical development
Mode, by unexposed dry film (or wet film) develop remove, spill copper face, the dry film (or wet film) exposed stays in plate face
On, as resist layer.
In circuit manufacturing process, due to the influence of various factors, many disadvantages can be produced, as dry film wipes flower, dew copper, film
The problems such as broken, rejection film.Circuit board internal layer circuit is acid negative film etch process, and dry film (or wet film) wipes flower, dew copper problem can be led
Open lines problem is caused, in addition, circuit board outer layer circuit is positive etch process, dry film, which wipes flower, dew copper, rejection film problem, to be caused
Open lines or short circuit problem.Dry film (or wet film) problem causes out the appearance of short circuit problem after developing in order to avoid circuit, especially
It is to there may be film rubbish or wipe to spend, it may occur that the lot size problem of positioning, so typically, it is necessary to use after circuit development
Optical detection apparatus detects to circuit surface, avoids opening short circuit problem caused by dry film (or wet film) problem is possible.
AOI (Automatic Optic Inspection, i.e. automatic optics inspection) is the principle by optical reflection, will
The method of pcb board face scanning obtains image, and the image for arriving engineering specification figure and actual scanning in computer carries out intelligence
Analysis contrast, the difference of reality and standard is found out, and difference is recorded beyond the place of setting range.AOI system is general
Completed by two machines：AOI scannings main frame (i.e. automatic optics inspection scanning main frame), for finding out discrepancy and recording its seat
Mark；VRS (Verify Station) maintenance station-Video cameras (i.e. maintenance station returns and looks into equipment) march to defective seat automatically
Cursor position, PCB image is shown with the state of amplification and goes to confirm for operator on a display screen, repair defect.
Traditional PCB repair methods are that pcb board face is detected using AOI scanning main frames, and Hua great is slightly wiped when having
During copper face, manual repairing；When thering is rejection film, dew copper, circuit to wipe flower, it is necessary to which dry film (or wet film) is stripped, then re-start line
Road is shifted, and not only efficiency is low for the method, cost is high, it is necessary to all be done over again especially in lot size problem, is extremely wasted into
This, and the quality decline after doing over again, it is totally unfavorable to reliability, all it is at present to use this traditional repair method in industry
Overhaul PCB circuits.
