Introduction

Bong-Ha Hwang is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of substrate inspection, holding a total of 9 patents. His innovative methods have enhanced the efficiency and accuracy of inspection processes in various applications.

Latest Patents

One of his latest patents is a method of inspecting a substrate. This method involves a substrate-inspecting apparatus equipped with a projecting module that projects patterned light onto a substrate fixed on a stage. An inspecting module with a camera captures images and inspects multiple regions of the substrate step by step. The process includes setting an inspection order based on the substrate's lengthwise direction, estimating height displacement of target regions, and adjusting the inspecting module's height accordingly. This innovative approach significantly reduces inspection time.

Another notable patent is an inspection method for boards. In this method, a measurement area is established on a board, and both reference and measurement data are acquired. A conversion condition is then set for the measurement area, and a conversion relation is determined based on the distortion degree between the reference and measurement data. The validity of this conversion relation is verified through various checks, ensuring that the inspection area is accurately set to compensate for any distortion.
