Uses and Applications of Micron Hard

Market	Application	Type of material	Market trends and uses
Parts used in semiconductor manufacturing process	Punch for board	Cemented carbide	As CPU packages are becoming to be smaller, the hole diameter of the packages should be under 0.1mm. It is required that the material for the punches have small grinding allowance and high strength.
	Probe pin (IC inspection terminal)	Powder metal high speed steel	The development of high integrated IC requires small terminal pitch (0.1mm). High strength and thin wire (50-70m) is needed instead of conventional W wire.
Printer	Dot pin	Powder metal high speed steel and cemented carbide	Use of newer technology for inkjet and laser has decreased the need of this product. However this item is still used for ATMs, and printers used in business in China and Europe.
Optical machine parts	Ferrule molding pin, light switch pin	Cemented carbide	Growth in needs for ultra high accuracy grinding process (submicron tolerance). Stopper pin for light path switch
Automobile	Electrode to make nozzle hole of fuel injector	Cemented carbide	As nozzle holes continue to get smaller for environmental regulations, diameter of electrode to make the holes need to be 0.15mm or less. It is required that the material for electrode is more rigid and hard.
Others	Gage, catheter guide wire	Cemented carbide and powder metal high speed steel	Gages needed for ferrule hole inspections are increasing. The diameter accuracy of this material is highly effective. Material can replace current Ni-Ti metal being used for catheters for thin blood veins.
