Board inspecting apparatus and board inspecting method using the same
The board inspecting apparatus include a measuring section obtaining measurement data for at least a portion of a board, a processing section comparing the measurement data and pre-obtained reference data, based on feature objects set on the board, to perform warpage compensation and inspecting the board with warpage compensated, a display section displaying ranges adjusting a first level of an inspection speed and a second level of a precision of the warpage compensation, and an input section receiving, from a user, inputs for the first and second levels as a specific setting combination having a trade-off relationship. The processing section, when the inspection speed and the precision are established, designates a specific option corresponding to the inspection speed and the precision among options increasing the precision so that the specific option is applied. Thus, users' convenience may be improved, and users may easily set options for distortion compensation.
1. A board inspecting apparatus, comprising:
a measuring section obtaining measurement data for at least a portion of a board;
a processing section comparing the measurement data of the board and previously obtained reference data of the board, based on a plurality of feature objects set on the board, to perform warpage compensation for the board, and inspecting the board in which warpage is compensated; and
a display section displaying ranges for adjusting a first level of an inspection speed according to the warpage compensation and a second level of a precision of the warpage compensation; and
an input section receiving, from a user, an input for the first level of the inspection speed and the second level of the precision as a setting combination that is specified to have a trade-off relationship,
wherein the processing section, when the inspection speed and the precision are established, designates a specific option corresponding to the established inspection speed and the established precision among a plurality options for increasing the precision of the warpage compensation so that the specific option is applied.
2. The board inspecting apparatus of claim 1 , wherein the display section displays the first level and the second level, respectively, as a first step and a second step which are discrete, or as a first weight ratio and a second weight ratio which are continuous.
3. A board inspecting method using a board inspecting apparatus performing warpage compensation of a board serving as a measurement target and inspecting the board with warpage compensated, the board inspecting method being performed by the board inspecting apparatus, the board inspecting method comprising:
displaying ranges for adjusting a first level of an inspection speed according to the warpage compensation and a second level of a precision of the warpage compensation;
receiving, from a user, an input for the first level of the inspection speed and the second level of the precision as a setting combination that is specified to have a trade-off relationship;
compensating warpage of the board based on feature object on the board, according to the setting combination of the first level of the inspection speed and the second level of the precision; and
inspecting an inspection area of the board in which the warpage is compensated;
wherein in compensating warpage of the board, when the inspection speed and the precision are established, a specific option corresponding to the established inspection speed and the established precision among a plurality options for increasing the precision of the warpage compensation is designated so that the specific option is applied.
4. The board inspecting method of claim 3 , when displaying the first level and the second level, wherein the first level and the second level is respectively displayed as:
a first step and a second step which are discrete, or
a first weight ratio and a second weight ratio which are continuous.
5. A computer readable non-transitory recording medium recording a program implementing the board inspecting method of claim 4 .
6. A computer readable non-transitory recording medium recording a program implementing the board inspecting method of claim 3 .
