ASIDA LJ101A FPC Character Inkjet Printer

Overview

The ASIDA LJ101A FPC Character Inkjet Printer is an industrial-grade, non-contact PCB and flexible printed circuit (FPC) marking system engineered for high-precision, high-reliability alphanumeric, logo, and 2D barcode printing directly onto rigid and flexible substrates. Unlike traditional screen-printing methods—requiring stencils, solvent-based inks, lengthy drying ovens, and extensive waste handling—the LJ101A employs piezoelectric inkjet technology combined with real-time CCD vision-guided registration to deliver consistent, traceable, and environmentally compliant marking at production-line speeds. Its core architecture integrates a closed-loop ink delivery system, automated printhead maintenance, and UV-curable ink formulation, enabling immediate post-print curing without thermal stress on heat-sensitive FPC materials. Designed specifically for semiconductor packaging support, HDI board manufacturing, and advanced SMT assembly lines, the system supports Industry 4.0 integration through standardized Ethernet/IP and Modbus TCP interfaces.

Key Features

• CCD-based three-point automatic registration: Achieves ≤35 µm positional repeatability across variable PCB geometries and surface reflectivity conditions.
• Piezoelectric printhead (KM1024, 14 pL droplet volume): Enables stable, low-maintenance jetting of UV-curable ink with fine-feature fidelity down to 70 µm line width and 0.5 mm character height.
• Fully enclosed, zero-waste ink circulation system: Includes auto-purge, self-cleaning cycles, and sealed ink reservoirs to minimize operator intervention and solvent exposure.
• UV-LED curing module with active thermal management: Delivers instantaneous ink polymerization (<1 s dwell time), eliminating conveyor ovens and preserving dimensional stability of polyimide-based FPCs.
• Adaptive substrate handling: Supports both rigid PCBs (0.1–6 mm thickness) and flexible circuits (including rolled or pre-cut FPCs) via programmable vacuum table zoning and edge-clamp compatibility.
• Intuitive HMI with recipe-driven operation: Touchscreen interface stores and recalls print layouts, serial number sequences, date/time stamps, and 2D Data Matrix/QR code configurations per job lot.

Sample Compatibility & Compliance

The LJ101A accommodates standard PCB formats from 170×220 mm up to 660×610 mm, including multi-layer FR-4, Rogers laminates, and polyimide-based FPCs with coverlay or stiffener integration. It complies with IPC-A-600G and IPC-6012D requirements for permanent marking legibility, adhesion, and chemical resistance (tested per IPC-TM-650 2.6.25). Ink formulation meets RoHS 2015/863/EU and REACH SVHC thresholds. The system’s closed ink path and dry-air purge design align with ISO 14001 environmental management protocols, while its electrical architecture conforms to IEC 60204-1 (Safety of Machinery – Electrical Equipment) and CE/EMC directives.

Software & Data Management

Equipped with ASIDA PrintMaster v3.2 software, the LJ101A provides full audit-trail functionality compliant with FDA 21 CFR Part 11 (electronic signatures, user-level access control, and immutable log files). Operators define dynamic fields—including sequential numbering, batch IDs, and machine-readable codes—with optional integration into MES (e.g., Siemens Opcenter, Rockwell FactoryTalk) and ERP systems via OPC UA. All print jobs are timestamped, image-captured pre- and post-marking, and archived with metadata (ink usage, alignment offset, UV intensity logs) for full traceability across production shifts.

Applications

• Permanent component-side and solder-side identification on HDI, IC substrate, and fan-out wafer-level packages.
• Lot/batch tracking and UDI (Unique Device Identification) marking for medical electronics and automotive ADAS modules.
• Replacement of silk-screen processes in high-mix, low-volume PCB fabrication where rapid changeover and minimal setup time are critical.
• Direct marking of flex-rigid hybrids used in foldable displays and wearable sensor assemblies.
• Support for IPC-2581 and ODB++ data import, enabling direct translation of Gerber-based silkscreen layers into inkjet print paths without manual vector rework.

FAQ

Does the LJ101A support IPC-2581 or Gerber file import for automated print layout generation?
Yes — native support for IPC-2581 revision G and Gerber RS-274X allows automatic extraction of silkscreen layers, text objects, and fiducial coordinates.
What UV ink types are qualified for use with this system?
Only ASIDA-certified UV-curable inks (AS-UV-FPC-01 series) are validated for long-term printhead reliability and IPC-compliant adhesion; third-party inks void warranty and may cause nozzle clogging.
Can the system mark on curved or warped PCBs?
No — the LJ101A requires planar substrates within ±0.3 mm flatness tolerance across the print zone; warped boards must be pre-leveled using compatible vacuum fixtures.
Is remote diagnostics and firmware update capability available?
Yes — via secure TLS-enabled web interface with role-based authentication; updates require signed firmware packages verified by ASIDA’s public key infrastructure.
What is the recommended preventive maintenance interval?
Daily: printhead wipe cycle and ink viscosity check; Quarterly: CCD calibration verification and UV lamp spectral output measurement; Annually: full motion axis lubrication and encoder recalibration per ASIDA Service Manual SM-LJ101A-Rev4.
