Drilling of Microvias

UV laser drilling of microvias with hole diameters < 50 µm

An efficient technology for the production of Microvias by opening the copper and removing the epoxy and glass fibre, in one processing step.

Advantages of UV laser drilling

• Drilling different materials
• RCC®
• PTFE
• FR4 and FR5
• Thermount®
• no delamination and reduced pink ring effect
• automatic correction of the position and of material dilation through
• registration of the fiducials and on-line scaling
• high precision and positional accuracy of the drill holes
• ideal drill hole geometry
