Check Plot Online is a PDF preview tool that provides engineers with an accurate, convenient view of circuit board designs prior to production.
 
"Traditional Gerber viewers don't always show the actual manufactured image
without time-consuming setup," said Ron Huston, founder and CEO. "Our new PCB Check Plot Online delivers an accurate representation of the final design, allowing engineers to avoid costly redesign efforts and project delays once a circuit board moves into the manufacturing phase."
 
Engineers upload Gerber files to the FreeDFM.com Web site and receive feedback within minutes. The feedback highlights potential design for manufacturability problems and suggests modifications. The free service requires no commitment to order.
