Multi Layer Ceramic Capacitors(MLCC)

Scheme Description:

Green Ceramic, A basic capacitor consists of two conducting electrodes separated by an insulating dielectric material.  Multi-layer ceramic capacitors consist of a large number of closely spaced parallel electrodes between thin layers of a high-capacitance ceramic material.

Major Considerations:

• Nuisance dust in ‘dry’ dicing operations
• Blade clogging
• Layer smearing and shorting

Saw:

• 7124, high level of automation, large blade size for better Cost -of -Ownership

Blade:

• 4″ Nickel (standard or serrated edge) and steel core Nickel Blades
• Diamond grit size: 30 – 70 microns
• Thickness: .006″ – .014”

Process Parameters:

• Feed rate: 50-250 mm/sec
• Spindle speed: 12 – 18 krpm
• Possible for both  dry  and wet dicing
• Relatively frequent dressing to clean blade from debris
