Simplifying the PCB Ordering Process

By The MacroFab Team  |  December 13, 2016

We’re always looking for new ways to make it easier to build and order your PCBs. The challenge is that a lot of the applications and file formats that are commonly used in the manufacturing industry weren’t designed to accommodate a modern automated manufacturing platform, forcing people to have to fill in the gaps when critical information is missing.

One of the most time-consuming examples of this is assuring correct orientation of components. Between how the component is defined in the datasheet, drawn in your EDA tool, and physically packaged on carrier, a lot of time and care must go into ensuring that component orientation is correct. An especially frustrating example are LEDs: some manufacturers consider pin 1 to be the cathode, others the anode, and there isn’t a clear standard in the industry that everyone follows to make sure these parts are oriented correctly.

Automated Component Orientation

We decided the best way to solve this is to remove the burden of component orientation from our customers. All we now require is that you verify that the centroid data (center location) of your component is correct, and our automated manufacturing platform will take on the work of setting the orientation for you. Our system will automatically analyze the silkscreen data, paste data, and interconnectivity to determine the most likely orientation with feedback from our trained assembly techs before final production. If you wish to override your silkscreen, or a component can have multiple likely orientations and you want it to be oriented in a non-standard way (such as a FFC connector facing inwards), you can let us know by using the PCB Assembly Notes feature.
