PCB

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
