Mark Laing Hi there I have covered a number of areas of process engineering in this blog over the past few months and there is now an opportunity to see how these areas all come together next week in our Webinar titled “World Class Process Preparation”. We will be discussing a number of ways that the users of Valor MSS can streamline their process preparation tasks to make them more efficient and … Read More

Mark Laing Hi there One of the least efficient areas in PCB assembly concerns the creation and management of package data that will be consumed across the shop-floor. For example DFM processes rely on accurate package data to determine component to component spacing issues or using accurate pin terminus contact data to ensure that solder joints will form correctly. Accurate package data is critical for DFT analysis … Read More

Mark Laing Hi there Within the Valor MSS Process Preparation suite, we have the best DFA capability that exists in the market. There are a number of checks that are performed that are necessary for PCB assemblers to execute prior to starting a design in production. Being able to know if fiducials on the board are near similar pads or vias is important to ensure that placement and inspection equipment don’t … Read More

Testability versus Accessability

Posted by Mark Laing

Mark Laing Hi there Test Engineers are typically given the requirement to get 100% of nets probed at electrical test with the thinking that this delivers 100% testability. Unfortunately 100% accessibility is not the same as 100% testability. There are a number of reasons why this is not the case but here is a easy one. Typical boards contain integrated circuit (IC) components and power supplies. These power supplies … Read More
