PCB Makers Trialing AI-based Recognition Modules to Support AOI

Reading time ( words)

Taiwan-based PCB makers are trialing AI-based recognition modules to hike accuracy for automatic optical inspection (AOI), according to a Digitimes report. AOI captures images of semi-finished products based on machine vision and determine whether they have defects based on machine learning. AOI is widely used in the PCB sector, taking up 64% of AOI use and followed by display panel industry with 15%.

To achieve high yield rates, PCB makers usually set strict parameters for AOI. AOI equipment is sensitive to ambient light, and can make wrong judgments under interference of slight external light. As a result, AOI has an over-screening rate of 70%, that is, 70% of AOI-determined defects are actually not defects. PCB makers have to conduct labor-based secondary inspection following AOI.

To solve the over-screening problem, the PCB manufacturing industry is trailing AI-based recognition modules to aid AOI. AI-based recognition modules can self-define the scope of defects based on AI-based learning, and efficiently determine if there are defects.

Jan Pedersen of NCAB Group is deeply involved in IPC standards development surrounding ultra HDI and keeps his finger on the pulse of the industry surrounding this type of fabrication. With Asia still dominating this area, Jan sees the need for U.S. and European PCB fabricators to make the investment if they want to stay competitive.

Understanding the UHDI Market

11/28/2022 | I-Connect007 Editorial Team
The more we investigate UHDI in the current market, the more advanced packaging becomes a part of the conversation. Yet there are so many questions to be answered. The I-Connect007 Editorial Team met with Calumet’s Todd Brassard and Meredith LaBeau recently to get answers to these questions and find out where the UHDI market is headed.

Electronica: Picking Up Where We Left Off

11/18/2022 | Nolan Johnson, I-Connect007
The productronica/electronica pairing of trade shows is an experience unlike any other; anyone who has ever attended is likely to back me up on that claim. This year’s iteration of electronica, taking place in Messe Munich, Nov. 15-18, is no exception. I-Connect007 was onsite to gather the news and share our impressions of the show. First, the show’s attendance was rumored to be in the 60,000+ range. This number sure seemed to be reasonable given the crowd sizes we witnessed.
