Overview
The Zhengye ZYCB21 Precision PCB Laminate Thickness Gauge is an engineered metrology instrument designed for high-accuracy, non-destructive thickness measurement of rigid and semi-rigid planar substrates used in printed circuit board (PCB) manufacturing and quality assurance. It operates on the principle of mechanical displacement sensing via a calibrated linear encoder coupled with a precision-ground granite base and adjustable measuring anvil assembly. The system delivers traceable dimensional data compliant with IPC-4101 and IPC-TM-650 standards for base material characterization, enabling consistent verification of copper-clad laminates (CCL), prepreg stacks, core materials, and finished multilayer boards. Its fixed-base architecture ensures minimal thermal drift and mechanical hysteresis, supporting repeatable measurements across production shifts and laboratory environments.
Key Features
- Extended throat depth (≥300 mm) accommodates large-format PCB panels up to 610 × 610 mm without repositioning
- High-resolution mechanical measurement system with ±0.003 mm accuracy (as verified per ISO 14253-1:2017 geometric product specifications)
- Dual-unit display interface: seamless toggle between metric (mm/µm) and imperial (in/mil) units without recalibration
- Backlit LCD readout with three-decimal-place resolution (0.001 mm) and real-time stability indication
- Zero-point offset function at any physical position—enabling differential thickness profiling across uneven or warped substrates
- Grade A black granite base plate (JIS B 7512 compliant) with surface flatness ≤0.002 mm over 300 mm, providing long-term dimensional stability
- Foot-switch activation for hands-free operation—reducing operator-induced parallax error and improving throughput in high-volume QA stations
- Modular design supports optional integration with SPC software modules for automated data logging, control chart generation, and statistical process monitoring
Sample Compatibility & Compliance
The ZYCB21 accepts rigid and flexible-rigid hybrid substrates including FR-4, polyimide, BT resin, ceramic-filled laminates, and metal-core PCBs. Sample thickness range spans 0.05 mm to 8.0 mm, with minimum sample size of 50 × 50 mm and maximum supported weight of 5 kg. All mechanical components conform to RoHS Directive 2011/65/EU. Measurement methodology aligns with IPC-TM-650 2.2.17.1 (Thickness of Rigid Laminates) and ASTM D1777–19 (Standard Test Method for Thickness of Textile Materials). Calibration certificates are issued traceable to CNAS-accredited laboratories (ISO/IEC 17025:2017), with optional NIST-traceable documentation available.
Software & Data Management
When equipped with the optional SPC module, the ZYCB21 interfaces via USB 2.0 or RS-232 to Windows-based host systems running Zhengye’s certified SPC Suite v3.2. The software supports automated data capture per measurement cycle, configurable X-bar/R and Cpk charts, assignable cause tagging, and export to CSV, Excel, or PDF formats. Audit trail functionality records user ID, timestamp, calibration status, and measurement parameters—meeting requirements for GLP/GMP documentation and FDA 21 CFR Part 11 electronic record compliance when deployed with validated user authentication and electronic signature protocols.
Applications
- Final inspection of copper-clad laminates prior to etching and drilling
- In-process verification of layer stack-up uniformity in multilayer PCB fabrication
- Supplier qualification testing against IPC-4101 specification sheets
- Failure analysis of warpage-related thickness variation in thermally cycled boards
- Calibration reference for inline optical thickness sensors in automated AOI lines
- Material lot acceptance testing in contract manufacturing organizations (CMOs)
FAQ
What is the recommended calibration interval for the ZYCB21?
Annual calibration is advised under normal usage; however, quarterly verification using certified gauge blocks (e.g., Class 0, 0.5 mm and 2.0 mm) is required per internal QA procedures.
Can the ZYCB21 measure flexible PCBs or coverlay films?
No—it is optimized for rigid and semi-rigid substrates only. Flexible materials require contactless methods such as laser triangulation or capacitance-based gauges.
Is the granite base pre-leveled and vibration-isolated?
The base includes adjustable leveling feet and is supplied with anti-vibration rubber pads; installation on a stable, level workbench (flatness ≤0.02 mm/m²) is mandatory for specified accuracy.
Does the foot switch support programmable trigger logic?
The standard foot switch provides momentary contact closure; programmable logic requires custom firmware upgrade and is available under OEM agreement.
How does the “zero at any position” function affect measurement uncertainty?
This feature introduces no additional uncertainty when performed on a clean, flat datum surface—per ISO/IEC Guide 98-3 (GUM) Annex H.3, the offset is treated as a systematic correction term applied before final reporting.
