Description
Technical field
A kind of method that the present invention relates to terminal check, especially signal receive transporter and can more intuitively examine
Standard inspection is remembered, and avoids indicating mistake.
Background technology
Terminal check is after optical check, carries out step by step circuit board being put into microscope or putting in the way of artificial
Inspection area on testing circuit plate under big mirror, as final inspection during shipment.Traditional manual operation inspection, when finding defect
Time be designated as scrapping district with black pen or white paint stroke again, wait after operation routine completing to be dried, it can indicate report as follow-up laser
The useless foundation with output electronic defects file.But, in defect record electronization simultaneously, such work pattern has several lack
Point: first, during by desk checking, owing to operator must open the layout relevant to circuit board when inputting computer
Case file, inputs the position scrapping district, inadequate automatization in operation routine, thereby increases and it is possible to have the potential of file opening mistake
Problem；Second, along with the trend of the small precise treatment of circuit board, the inspection area of single block arrangement also gets more and more, the most necessary
Determination check district is come, problem inconsistent with the position of computer input when this is likely to so that manually marking by several row, column
Produce；3rd, traditional black pen indicates with white paint pen, and its surface easily comes off, and causes the problems such as plate surface pollution.
After terminal check, product will be fed directly to client, if occur defective products, scrap differentiation distinguish mistake and labelling
Come off problems such as causing plate pollution, can cause scrapping of subsequent client product, and derivative cost improves, and the goodwill of company is also
May be impaired, accordingly, it would be desirable to a kind of more intuitive and improve that existing Check-Out Time is longer, be susceptible to mistake checking system and
Method.
