Abstract

Provided is a device for inspecting a film carrier tape for electronic component mounting which can efficiently discriminate true and pseudo failures, and also a method for confirming a pattern failure. This inspection device comprises a failure confirming unit. The confirming unit takes an image of one of image pickup zones etc. set as piece divisions in which a failure part of a wiring pattern detected by an image processor is positioned; displays the image pickup zone; and performs selective input operation to determine a visual discrimination result of whether at least one failure included in the displayed one image pickup zone is a true failure or all failure parts are pseudo failures. The images of the image pickup zones etc. including the failure parts are displayed in the decreasing order of sizes of the failure parts included in the image pickup zones.

Description

technical field [0001] The present invention relates to a detection device for printed circuit boards for electronic component mounting and a method for confirming pattern defects using the detection method, that is, for FPC and film carrier tape (TAB (Tape Automated Bonding) tapes, T-BGA (TapeBall Grid Array) tape, CSP (Chip Size Package) tape, ASIC (Application Specific Integrated Circuit) tape, COF (Chip On Film) tape, bimetallic (two-sided wiring) tape, multilayer wiring tape) Various parts of printed circuit boards for mounting electronic components, such as flexible printed circuit boards and hard printed circuit boards using materials such as glass fiber reinforced plastic substrates, have formed circuit diagrams. The image data obtained by photographing the parts is compared with the standard graphics. Thereby, defects in the circuit diagram are detected, and at the same time, detected defective parts are confirmed. It should be noted that the "printed circuit board f...
