This Eagle CAD User Language Program (ULP) creates the specific format surface mount XY location file, called a Centroid file, required by Screaming Circuits for prototype assembly. Download this file (Centroid_ScreamingCircuits_smd.zip) and unzip it into the “ulp” directory inside your Eagle directory. * Then, once your design is complete, simply run this ULP and include the generated file “<project-name> centroid.csv” in the zip file containing your BOM and Gerbers when you order prototype pcb assembly from Screaming Circuits.
