Problems solved by technology

[0005] However, the following situations may occur, due to the long-term use of the inspection device, the hardware status of the inspection detector changes, thereby reducing the inspection reliability
In addition, since PCBs have different colors and reflectances depending on manufacturers, there may be cases where inspection reliability decreases when inspecting PCBs with different characteristics under the same inspection conditions

Embodiment Construction

[0034] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, the invention can be implemented in many different ways and should not be considered limited to the exemplary embodiments set forth herein. Of course, exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The size and relative sizes of certain layers and regions in the drawings may be exaggerated for clarity.

[0035] It will be understood that when an element or layer is referred to as being "on," "connected to," or "connected to" another element or layer, it can be directly on the other element or layer. Or on a layer, directly connected to another component or layer, or directly connected to another component or layer, or there may be an intervening component or layer between a com...

Abstract

The invention discloses a method of inspecting a testing device and a method of establishing measured variables of the testing device. In order to establish the illumination intensity of the test device, the test plate is installed in the test device. Next, the width of the frequency histogram of the captured image acquired by the camera of the inspection device is adjusted so as to avoid dark and bright areas. Thereafter, by adjusting the frequency histogram to near the middle of the graph, the illumination intensity of the inspection device is adjusted. Thus, the setting time of inspection conditions stored in the job file can be shortened to increase user convenience, and measurement errors caused by erroneous setup can be reduced to improve inspection accuracy.

Description

technical field [0001] The invention relates to a method of inspecting a testing device and a method of establishing measured variables of a testing device. More particularly, the present invention relates to a method of checking the current condition of a non-contact inspection device using a light source and a camera, and a method of establishing an optimal measurement condition corresponding to a characteristic of an inspection board. Background technique [0002] Mounting boards are used in various electronic devices in which electronic components are mounted on a printed circuit board (PCB). The mounting board is fabricated by plating solder on the pads of the bare board and then connecting the terminals of the electronic components to the solder-plated pads. [0003] Generally, in order to verify the reliability of a PCB mounted with electronic parts, it is necessary to inspect whether the PCB is manufactured well before or after the electronic parts are mounted. For...
