Menu DFM & Valor Services Utilizing the industry leading Valor Enterprise 3000 software. You are here: Home Services Overview DFM & Valor Services Automated & Manual DFM Services Freedom CAD has the capability to perform DFM & Valor services on all FCS designed products, as well as designs done by customers or outside agencies. These reviews are done primarily through the use of Valor’s Enterprise 3000 software (now owned by Mentor). As a supplement to the automated analysis, a visual check is done to review the items not automatically checked. Every Freedom CAD design goes through our Valor/QA process a minimum of two times to ensure that your design is error free. Standard Deliverables Automated Valor Checks Manual Checks The automated Valor checks fall into the categories below. The primary checks performed are listed in each category. The checks done are predominantly fab checks. The Enterprise 3000 tool has limited automatic checks for potential assembly issues. The rules used for these checks have been developed by Freedom CAD based on industry standards, along with experience and feedback from suppliers. FCS has the ability to use unique customer or supplier specific rules if desired.
