Splet20. jun. 2014 · This particular project involved the detection of the defect exist in a PCB board. A Printed Circuit Board (PCB) is a circuit board consists of electronics components mounted on the surface. Basically, to produce a perfect bare PCB board, inspection of PCB is necessary to reduce defects. We apply the machine vision concept to inspect the bare … SpletIC mold defect/blister inspection. Check for flaws or bulging on IC molds using machine vision. ... Using a high-pixel machine vision allows an entire PCB to be captured within the field of view. This enables simultaneous inspections to measure connector pitches and other items, as well as to recognize/judge character information and 2D codes. ...

SpletPCB manufacturing depends significantly on AOI. It ensures that every board can deliver the high efficiency needed in intricate electrical devices. When AOI finds a PCB defect, it marks the PCB and sends it back for rework. This procedure may take place in … Splet3. PCB Defect Detection by Using Machine Learning 3.1. Defect Detection By Using Artificial Neural Networks Wu, Zhang, Kuang, & Lu (2008) argued that the currently inspection for solder paste which are mainly performed by laser-based systems is not practical due to high cost and low inspection speed[6]. They syndrome associated with strep
