A Better Way to Clean Circuit Boards

Foreign material, dust, lint, foreign object damage (FOD) — whatever you call it — when it's on your circuit boards, it's never a good thing. For engineering managers tasked with reducing waste and increasing quality, there are many ways to eliminate foreign material in your processes ...
What Is Resolution?

Automated Optical Inspection (AOI) systems rely on something we take too much for granted: the lens system. The lens system provides the image acquisition capabilities that are needed in all AOI systems — in all cameras, whether for AOI or for machine vision, for security applications ...
Dual Technology Automated Optical Inspection

The single inspection approach does not provide all of the answers that a production engineer needs to keep the production line running at maximum yield. With components ranging from the tiny 01005 up to long SMT or THT connectors, the AOI programmer needs superb image resolution, a ...
Overcoming the limitations of Flying Probe Test

When flying probers first entered the market in the late 1980s, their utility was largely limited to testing prototypes and circuits that had no good test points. The bed-of-nails in-circuit test was still king and remained that way for many years. But ICT demands a costly fixture ...
Ionic Cleanliness Testing

Cleanliness of PCB assemblies is easily and accurately measured through the use of a Contaminometer, a test machine that complies with IPC-TM-650 2.3.25. The ROSE Test (Resistivity Of Solvents Extracted) is a quick and easy test that takes no more than 15 minutes, on average, to perform ...
Enhanced BGA Inspection with Advanced Technology

Years of BGA imaging experience have resulted in a complete understanding of the actual BGA placement process. With a solid understanding of the placement process, software engineers have been able to develop image analysis software that is easy to use, while providing the relevant ...
