Used Dicing Saw Buying Guide: DISCO vs ADT Checks
Compare used DISCO and ADT dicing saws. Check blade fit, spindle records and sample-cut acceptance criteria before requesting a quote.
Choose a used dicing saw by documenting your workpiece and sample-cut requirements, then comparing the exact machine configuration and blade setup. Review spindle and maintenance records, agree on sample-cut acceptance criteria, and request an itemized quote for the offered saw.
How do you choose a used dicing saw for your workpiece?
Start a used dicing saw search with a sample-cut requirement, not a preferred brand or an advertised discount. Document the wafer or substrate material, dimensions, thickness, mounting tape and frame, street layout, intended cut depth and inspection criteria. Ask each supplier to propose a documented machine and blade configuration for that application.
If you are still selecting the process, use the laser scribing and dicing guide to prepare questions for an applications engineer. Request application-specific trials before deciding between processes.
DISCO vs ADT: how do you compare used dicing saw models and options?
DISCO's DAD3221 specification lists a single spindle, a maximum workpiece size of six inches, and optional Non-Contact Setup for blade-height measurement. Use that as a model-specific example, not a specification for another DAD model or proof of the configuration on a used unit.
ADT offers dicing saws, dicing blades and dicing peripherals. Request the exact model's specification sheet and installed-option list before comparing it with a DISCO offer.
Ask both suppliers for the same evidence:
- Workpiece and mounting: document the supported workpiece, frame and chuck configuration for the offered unit.
- Spindle and blade setup: request spindle identification, flange details, the approved blade specification and service records.
- Alignment and inspection: request the installed camera, alignment and kerf-inspection option list, demonstrated on your sample.
- Operation: request the software version, license-transfer terms, manuals and required utilities.
- Service: request a written repair scope, local support arrangements and included spare-parts list.
How do you confirm dicing blade and mounting compatibility?
Ask your applications engineer to specify blade dimensions, bond, grit, exposure and the intended cutting recipe. Have the seller confirm the spindle/flange assembly and supply the corresponding approved documentation. Do not infer compatibility from a shared brand name.
The DISCO NBC-Z blade page is a starting point for a blade inquiry, not a recommendation for either saw. Submit the approved blade specification and exact saw configuration when requesting consumables.
How do you inspect a used dicing saw spindle, motion and service history?
Request maintenance records, spindle repair or replacement reports, calibration results and available alarm logs. Ask the service provider to reconcile recorded hours with the documented maintenance history; do not impose an unsourced universal replacement interval.
Arrange an inspection by a qualified technician using the applicable service procedure. Include checks of spindle condition, stage motion, alignment, blade-height setup, workholding, water delivery and interlocks as specified for the model. Record missing documentation and unresolved faults before negotiating the final condition of sale.
How do you use a sample cut to accept a used dicing saw?
Agree on a written trial using representative material, tape, frame and the proposed blade. Before the run, define:
- Test recipe: blade identification, setup, speed/feed settings, cut depth and the number of samples or run duration.
- Inspection method: how to measure kerf width, cut placement, chipping and depth; name the metrology and inspection locations.
- Pass/fail limits: have your process engineer supply numerical limits from the product drawing or qualification plan.
- Delivered evidence: retain recipe settings, images, measurement results and machine identifiers with the acceptance report.
- Remedies: agree on rework, repeat trials and rejection terms if the saw fails the agreed criteria.
Ask which acceptance checks will be repeated after installation, and who will provide the samples, technician and metrology.
What should you send with a used dicing saw RFQ?
- Workpiece material, dimensions, thickness, tape and frame details.
- Desired machine model, installed options and chuck configuration.
- Approved blade specification and spindle/flange documentation.
- Maintenance records, spindle service reports and calibration results to request from the seller.
- Sample-cut plan, inspection method and process-engineer acceptance criteria.
What should a used dicing saw quote include?
Request separate line items for the saw, inspection, repairs, chuck/frame fixtures, blade tooling, packing, freight, installation and training. Use the used versus refurbished equipment guide to structure condition questions, then insist on an itemized scope for the actual offer.
Send the workpiece details, desired configuration and sample-cut plan in your quote request. Ask for current price, availability and delivery terms in writing rather than assuming a listing is ready to ship.
