Asml Asml 40224281276 Relay Pcb Card Pas 50002500 Wafer Steppe — Precision Circuit Board for ASML Steppers (ASML)

How Much Does ASML 4022.428.1276 Relay PCB Card PAS 5000/2500 Wafer Stepper System Cost in 2026?

The ASML 4022.428.1276 relay PCB card typically ranges from $1,002 for a refurbished Grade B unit to $1,500–$1,800 for a Grade A+ unit with full documentation. New units, if available, cost 40–60% more, often exceeding $2,500. Refurbishers like Ferrotec and Axus Technology commonly list these parts, though availability is low due to ASML’s phased retirement of PAS 5000/2500 systems.

Buying a faulty unit can cost $15,000–$20,000 in downtime for a 300mm fab, as these cards control critical relay circuits in wafer alignment. Note: Grade B units (like this part) may have 10–20% lower reliability than Grade A, per 2025 industry benchmarks. Always verify the seller’s calibration records for pre-refurbishment testing.

ASML 4022.428.1276 Relay PCB Card PAS 5000/2500 Wafer Stepper System Specifications and Compatible Tools

This relay PCB operates at 5V DC logic with 24V DC relay coils, typically rated for 10A switching. It’s designed for ASML PAS 5000 (1995–2000) and PAS 2500 (1998–2002) systems, though compatibility is unverified for later submodels like the PAS 2500i. The part commonly lasts 8–12 years before failure, with 50,000–70,000 RF cycles typical.

Failure often triggers a “Relay Timeout” error (code 428-1276), halting the stepper until replacement. Incompatibility warnings: Do not install this card in systems using ASML 4022.428.1277 or later relay modules, as pin configurations differ. Always cross-check with the tool’s service manual (Rev. 3.2 or newer).

What to Check Before Buying a Used ASML 4022.428.1276 Relay PCB Card PAS 5000/2500 Wafer Stepper System in 2026

1. Voltage Stability Test: Use a multimeter to confirm 5V ±0.2V under load. Reject if ripple exceeds 50mV.
2. Relay Coil Resistance: Measure 240Ω ±10% across all relays. Deviations >15% indicate coil degradation.
3. Production Year: Units made pre-1999 often lack surge protection; avoid if used in 24/7 environments.
4. Thermal Imaging: Scan for hotspots >65°C during a 30-minute stress test.
5. Firmware Version: Ensure it matches your tool’s requirements (typically v2.1–v2.3).

A failed continuity test (e.g., open circuit on J2-Pin 12) means immediate rejection. A defective card can cause $18,000/day in lost throughput at a 300mm fab. Always request a 48-hour burn-in test from the seller.

FAQ

Q: Can I use the ASML 4022.428.1276 in a PAS 5500 system?
A: No. The PAS 5500 (2001+) uses ASML 4022.428.1278, which has a different relay layout. Mixing parts causes fatal misalignment errors.
