What it is
The Disco KR15 is a compact linear actuator in THK’s KR series. The KR15 uses a full-ball LM guide actuator design with high rigidity, high accuracy, four-way equal load, and a space-saving form factor.[2]
How it works
General reference — not yet source-verifiedA dicing and grinding stage uses precise axis motion to place a workpiece and tool with fine positional control. A motion platform in this class supports repeatable feed, alignment, and stroke control for semiconductor singulation and material removal tasks.
Where it fits in the process flow
General reference — not yet source-verifiedDicing belongs near the end of wafer processing, after device fabrication and before die separation into individual parts. Grinding belongs in wafer thinning and backside preparation flows that precede or accompany singulation.
Applications
General reference — not yet source-verifiedThe KR15 family is suited to precision motion in semiconductor and microfabrication equipment. The class is used where accurate linear positioning, high rigidity, and compact packaging matter.
