Avalon PVC Checker function is interested FA team of SS Foundry.
They expect to find abnormal contact, metal and via automatically with PVC checker.
Currently they are using manual inspection with naked eyes on dual monitor.
one is Nexs layout, another is PVC picture. and compare.
Nexs show highlight trace for candidate failure net from test diagnosis.
Below picture is real PVC result of metal1 from SS new process.
Metal1 and Via1 are overlapped and the image is not clear.
AVALON Passive Voltage Contrast Checker (PVC) quickly and accurately validates the integrity of a circuit's conductivity and provides detailed. information for identifying suspect faults at via or metal traces. Stainless Steel [ SS ] foundry is a factory where castings are produced by melting metal, pouring liquid metal into a mold, then allowing it to solidify.
Currently, a thorough inspection is being done without the aid of any device on the dual monitor. Through Nex’s image layout, the PVC picture has been compared. In the Nex’s images, it shows some highlights and traces of any future failure or help detect any condition that may take place.
The picture below is a real PVC of metal1 from the stainless steel ‘s new process. Metal1 and Via1 are overlapping and the image is not clear and somehow hazy
