PCB

Scheme Description:

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” and “Z” matrixes
• Diamond grit size: 10,13,17 microns
• Thickness: .003” – 0.008”

Process Parameters:

• Feed rate: 50 – 150 mm/sec
• Spindle speed: 2” : 25 – 30 krpm
4” : 12 – 20 krpm
