Description
Technical field
The utility model relates to Photoelectric Detection instrument technical field, particularly a kind of detecting instrument that is used to detect the defective of printed circuit board (PCB) live width, circular hole.
Background technology
Because tradition uses visual mirror to measure at present, all need to use 50 times to 100 times tool microscope to finish by skilled operator.The operator must calculate these thin wires very carefully, in order not to make any any mistakes.
Work efficiency is descended, and measuring speed is slow.Beyond the limited speed, person's measurement is not quite similar to add the different operating simultaneously, so check that line quality quite is not inconsistent client's standard, so PCB detecting is more and more high for the requirement of precision now, and circuit requires more and more close, detects under the non-conformity of quality client standard, can't detect the last width of cloth and following wide or narrow phenomenon of circuit immediately, and then the problem of monitoring etching machine equipment parameter adjustment, so utilize traditional visual mirror mode to detect, do not meet very much the principle of efficient.Running time can not be oversize simultaneously, and not so eyes are easy to fatigue.Because the border judgment mode varies with each individual, be easy to take place different operating person measurement simultaneously with regard to different problems.Even because the factor of fatigue strength, same operator can be different at the measurement of different time, causes insecure result.
Therefore, the instrument that a kind of micro-optical imaging system and geometric parameter measurement system combine, the image shows after amplifying on computer screen, and image carried out analysis to measure, can save the personnel training time, reduce human cost, promote the etch process ability, reduce the product rejection rate, promote and connect enterprise competitiveness, increase the client and trust.
