Disco Corporation (6146.T): How It Works

• Primary products: dicing saws, grinders, polishers and allied precision machines used in wafer and package singulation, thinning and surface finishing.
• Consumables: dicing blades, grinding wheels, polishing pads and process-specific tooling sold repeatedly for installed systems.
• Services: installation, preventive maintenance, spare parts, operator training and remote diagnostics that generate recurring aftermarket revenue.
• Contract wafer processing: outsourced dicing/thinning/polishing services for fabless, foundry and OSAT customers who prefer on-demand processing.
• Recycling & refurbishment: trade-in, refurbishment and resale of used equipment plus parts reclamation that both supports sustainability and returns incremental revenue.

• Major equipment sales: one-time, often multi-year sales cycles with OEM/foundry capital budgets.
• Aftermarket consumables: high-frequency purchases tied directly to throughput and device mix.
• Recurring services & contracts: long-term service agreements and processing contracts that stabilize cash flow.
• Recycling/refurbishment sales: monetizes end-of-life assets and reduces customer total cost of ownership.

• Capital equipment sales: 60-65% - dicing saws, grinders, polishers.
• Consumables & parts: 12-18% - blades, wheels, pads and replacement parts.
• Maintenance & services: 8-12% - service agreements, training, spare parts supply.
• Contract wafer processing: 5-8% - fee-for-service dicing/thinning/polishing.
• Recycling/refurbishment: 2-4% - resale of refurbished machines and reclaimed parts.

• High-margin consumables tied to installed base utilization - as throughput grows, consumable sales scale predictably.
• Service contracts that lengthen customer lifetime value and lower churn.
• Engineering-focused product development improving throughput and reducing per-wafer cost, justifying premium equipment pricing.
• Contract processing fills factory idle capacity and converts capital equipment capability into steady service revenue.
• Refurbishment and recycling reduce capital intensity and extract value from end-of-life assets.

Disco Corporation (6146.T): How It Makes Money
