The most effective material utilisation will be achieved with boards or arrays of boards having their finished outline fit as efficiently as possible within the usable area of the panel . Test coupons must be within the usable area. If the entire panel is shipped to the customer, the customer may negotiate to have locating holes and/or break-away tabs for insertion or surface mount equipment located outside the sable area. Material utilisation may be increased by utilising the scoring process.
