Abstract
Abstract A packaged substrate inspecting apparatus comprises an imaging device for picking up images of substrates. Land images are extracted from the image of a non-packaged substrate and that of a packaged substrate. On the basis of the shapes of the land extracted from the non-packaged substrate and those of the packaged substrate, positional relationship between a part mounted on the packaged substrate and the land is determined to be utilized for deciding whether the mounted state of the part on the substrate is to be satisfactory or not.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A packaged substrate inspecting apparatus, comprising: land extracting means for extracting lands from images of a non-packaged substrate and a packaged substrate, respectively, which are produced by image pick-up means; positional relation extracting means for extracting positional relationships between the lands of said packaged substrate and the parts mounted thereon on the basis of geometrical data of the lands of said non-packaged substrate and said packaged substrate, said data being obtained by said land extracting means; and decision means for deciding the mounted state of said part on the basis of said positional relationship obtained by said positional relationship extracting means
Claim 2
Dependent Claim
101 words
A packaged substrate inspecting apparatus, comprising: land extracting means for extracting lands from images of a non-packaged substrate and a packaged substrate, respectively, which are produced by image pick-up means; positional relation extracting means for extracting positional relationships between the lands of said packaged substrate and the parts mounted thereon on the basis of geometrical data of the lands of said non-packaged substrate and said packaged substrate, said data being obtained by said land extracting means; and decision means for deciding the mounted state of said part on the basis of said positional relationship obtained by said positional relationship extracting means
Claim 3
Dependent Claim
24 words
A packaged substrate inspecting apparatus according to claim 1, wherein said geometrical data obtained by said land extracting means is subjected to chrominance-to-brightness conversion.
Claim 4
Dependent Claim
108 words
A packaged substrate inspecting apparatus, comprising: imaging means for picking up an image of a substrate; image cut-out means for cutting out an image portion within a plausible land existing range from said image obtained from said imaging means on the basis of previously inputted data concerning positions and geometrical configurations of a part; land extracting means for extracting the land from said cut-out image obtained from said image cut-out means; and decision means for determining the species of said part on the basis of the land data available from said land extracting means and said previously inputted data concerning the positions and geometrical configurations of said part.
Claim 5
Dependent Claim
108 words
A packaged substrate inspecting apparatus, comprising: imaging means for picking up an image of a substrate; image cut-out means for cutting out an image portion within a plausible land existing range from said image obtained from said imaging means on the basis of previously inputted data concerning positions and geometrical configurations of a part; land extracting means for extracting the land from said cut-out image obtained from said image cut-out means; and decision means for determining the species of said part on the basis of the land data available from said land extracting means and said previously inputted data concerning the positions and geometrical configurations of said part.
Claim 6
Dependent Claim
26 words
A packaged substrate inspecting apparatus according to claim 3, further including display means for indicating the result of said decision on the species of said part.
Claim 7
Dependent Claim
27 words
A packaged substrate inspecting apparatus according to claim 3, further including printer means for printing out the result of said decision on the species of said part.
