Abstract

An inspecting method for grasping the inspection result on an intermediate (or an n-th) treatment without long extension of time, in case predetermined treatments of a predetermined number (N times) are exerted on a plurality of sheets running on a conveyor line, before all the treatments of N-times are ended. The inspecting method for inspecting an object subjected to the predetermined treatment includes performing the predetermined treatment repeatedly by the N-times (N: a natural number of 2 or more) sequentially on the individual objects being conveyed on the conveyor line, and an inspecting step of testing such a leading one of the objects as has been subjected to the n-th (n: a natural number of 1 or more but N or less) treatment, and returning the tested object to after such one of the targets as was subjected to the n-th treatment.

Claims

1. A testing method for conducting a test on a plurality of sheet substrates having predetermined processing performed thereon, the testing method comprising:

a processing step of repeatedly performing the predetermined processing on the sheet substrates N times (N being a natural number of 2 or larger) in a sequential manner, while the sheet substrates are being transported on a conveyor line; and

a testing step of conducting a test on the first one of the sheet substrates among the plurality of the sheet substrates having the nth time processing (n being a natural number of N or smaller) first performed thereon, and returning the tested first sheet substrate to a spot behind one of the other sheet substrates having the nth time processing completed thereon,

wherein the predetermined processing in the processing step is printing processing performed by repeatedly printing silver paste on the sheet substrates, to form bumps with a predetermined height on the sheet substrates, and

wherein the testing step includes checking whether each of the bumps exists properly, has the predetermined height, and is located in a predetermined position.

2. The testing method according to claim 1, wherein

the testing step includes returning the tested sheet substrate to a spot after the last sheet substrate having the nth time processing last performed thereon.

3. The testing method according to claim 1, wherein

the testing step includes a test result notifying step of notifying the processing step of a result of the test conducted on the sheet substrates having the nth time processing completed thereon;

and

the processing step includes receiving the notification of the result of the test conducted to check the nth time processing from the testing step, and, when the test result is not good, stopping the processing being performed on the sheet substrates.

4. The testing method according to claim 1, wherein

the testing step includes a test result notifying step of notifying the processing step of a result of the test conducted on the sheet substrates having the nth time processing completed thereon;

and

the processing step includes receiving the notification of the result of the test conducted to check the nth time processing from the testing step, and, only when the test result is good, performing the (n+1)th time processing on the sheet substrates.

5. A testing and processing system that performs predetermined processing and conducts a test on a plurality of sheet substrates being transported on a conveyor line, the testing and processing system comprising:

a processing device that repeatedly performs the predetermined processing on the sheet substrates N times (N being a natural number of 2 or larger) in a sequential manner, while the sheet substrates are being transported on the conveyor line; and

a testing device that conducts a test on the first one of the sheet substrates among the plurality of the sheet substrates having the nth time processing (n being a natural number of N or smaller) first performed thereon, and returns the tested first sheet substrate to a spot behind one of the other sheet substrates among the plurality of the sheet substrates having the nth time processing completed thereon,

wherein the predetermined processing in the processing device is printing processing performed by repeatedly printing silver paste on the sheet substrates, to form bumps with a predetermined height on the sheet substrates, and

wherein the testing device checks whether each of the bumps exists properly, has the predetermined height, and is located in a predetermined position.

6. The testing and processing system according to claim 5, wherein

the testing device returns the tested sheet substrate to a spot after the last sheet substrate having the nth time processing last performed thereon.

7. The testing and processing system according to claim 5, wherein

the testing device includes a test result notifying unit that notifies the processing device of a result of the test conducted on the sheet substrates having the nth time processing completed thereon;

and

the processing device receives the notification of the result of the test conducted to check the nth time processing from the testing device, and, when the test result is not good, stops the processing being performed on the sheet substrates.

8. The testing and processing system according to claim 5, wherein

the testing device includes a test result notifying unit that notifies the processing device of a result of the test conducted on the sheet substrates having the nth time processing completed thereon;

and

the processing device receives the notification of the result of the test conducted to check the nth time processing from the testing device, and, only when the test result is good, performs the (n+1)th time processing on the sheet substrates.

9. A processing device of a testing and processing system that performs predetermined processing and conducts a test on a plurality of sheet substrates being transported on a conveyor line, the testing and processing system comprising the processing device and a testing device,

the processing device configured to repeatedly perform the predetermined processing on the sheet substrates N times (N being a natural number of 2 or larger) in a sequential manner, while the sheet substrates are being transported on the conveyor line, and
