PCB
Printed Circuit Board (PCB) is composed of layers of copper and FR4/5 or BT resin. PCB is used as a substrate for mounting. Typical thickness is 0.3 mm to 2 mm
Major Considerations:
Cut quality:
- Copper burrs
- Smearing
Saw:
Automatic (7120 series) or fully auotomatic (7220 series) dicing systems – enhanced process control tools with very high automation level, large area capabilities
Blade:
- 2″ and 4″ Nickel blades (serrated and standard edge) “T”, “V” matrixes
- Diamond grit size: 10 – 50 µm
- Thickness: .003″ – .0012” (0.075 – 0.3 mm)
Process Parameters:
- Feed rate: 50 – 150 mm/sec
- Spindle speed: 2″ : 25 – 30 krpm
4″ : 12 – 20 krpm
