Reverse engineering study of diamond coated router bit using SEM and EDS method / Liew Fiji Kiew ... [et al.]

Router bit is the most critical material during printed circuit board (PCB) depanelization process. Industrial records showed that replacing ordinary router bit with diamond coated router bit can save 80% of the depanelization cost. Hence, the quality and reliability of diamond router bit become a...
