    • Printed Circuit Board Repair

    Authorized Repair Center

    We specialize in repairing printed circuit boards for OEM suppliers, Mimaki, Roland, and Mutoh dealers, as well as direct end-users. Let us restore your board to full working condition — typically for a fraction of the cost of a new replacement.
     
     
    Unlike others who merely imitate what we do, we bring over 40 years of specialized experience repairing industrial equipment. Our in-house lab is equipped with professional-grade tools—including oscilloscopes, precision multimeters, high-powered microscopes, hot-air/BGA rework stations, and multiple dedicated printer test beds of the exact models we support. This allows us to accurately diagnose, repair, and fully test Mimaki, Roland, Mutoh, and other printer PCBs faster and more reliably than anyone else.
     

     *Turn-around time is often the same day the part is received. No one is faster!

    Printed Circuit Board (PCB) Repair Process – Step by Step

    Here’s how we professionally repair printer main boards, slider boards, head driver boards, power boards, etc. (typical for Mimaki, Roland, Mutoh, etc.):

              Receipt & Initial Inspection

      • Board is logged in.
      • Visual inspection under stereo microscope for obvious damage: burnt components, cracked solder joints, corrosion, liquid damage, blown fuses, etc.

              Customer Symptom Report Review

      • We match your described symptoms (e.g., “no power,” “Error 123,” “head not firing on channel 4,” “random reboots”) against common failure patterns for that exact board model.

              Electrical Testing (when possible before disassembly)

      • Power-up on a test bench with current-limited PSU to avoid further damage.
      • Check main voltage rails (+5 V, +3.3 V, +24 V, +42 V, etc.).
      • Use oscilloscope to verify clock signals, reset lines, and basic communication.

              Detailed Microscopic Diagnosis

      • Remove any conformal coating or shields if needed.
      • Inspect solder joints, especially high-current MOSFETs, DC-DC converters, and BGA/LGA chips.
      • Look for hairline cracks, tombstoned passives, delaminated layers, and corroded vias.

              Schematic & Boardview Research

      • We maintain an internal library of Mimaki, Roland, Mutoh, and most wide-format printer schematics/boardviews.
      • Trace affected circuits to identify the exact failed component(s).

              Component-Level Repair (most common fixes)

      • Replace failed MOSFETs, drivers, voltage regulators, capacitors, and fuses.
      • Repair broken traces and vias with jumper wires or conductive epoxy.

              Reassembly & Full Functional Testing

      • Board is reinstalled on our in-house test printer (same model or compatible).
      • Perform extended tests to catch intermittent faults.

              Preventive Measures (when applicable)

      • Add thermal pads or improve airflow if overheating was the root cause.

              Final Cleaning & Packaging

      • Board is packed in anti-static shielding with foam support to prevent flexing during shipping.

     

    Typical turnaround: 1–5 business days once we receive the board.
