What problem does this solve?

Electronics manufacturers need to print extremely small, high-resolution identification marks (serial numbers, QR codes, date codes, lot numbers) on PCBs, microchips, resistors, and SMD components where available print area is often under 5 mm². The marks must be scannable at micro scale, survive soldering temperatures, and keep pace with high-speed SMT (Surface Mount Technology) production lines.

Solution Description

The S1000 Small Character (CIJ) Printer is specifically engineered for micro-marking applications. It prints characters as small as 1.2 mm in height with sharp, defined edges at speeds up to 400 m/min (100 m/min for micro-character mode). The advanced nozzle design, combined with automatic viscosity measurement, dynamically adjusts ink viscosity based on ambient temperature and humidity to ensure consistent droplet formation at micro scale.

The printer’s compact printhead integrates flexibly into SMT lines, solder paste inspection (SPI) stations, and pick-and-place machines. Real-time monitoring and automatic flushing prevent nozzle clogging, while remote fault diagnosis minimizes downtime on 24/7 electronics production lines.

Key Benefits

  • Prints characters as small as 1.2 mm with crisp, scannable edges
  • Micro QR code and high-density QR code printing for component traceability
  • Automatic viscosity adjustment adapts to temperature/humidity changes in real time
  • Compact printhead integrates into tight SMT line spaces
  • Automatic nozzle flushing prevents clogging without stopping production
  • Remote fault diagnosis reduces maintenance time and line downtime
  • Supports serial numbers, date codes, lot numbers, and 2D codes

Target Customers

  • PCB (Printed Circuit Board) manufacturers
  • Semiconductor and IC package manufacturers
  • SMT (Surface Mount Technology) assembly houses
  • Electronic component manufacturers (resistors, capacitors, connectors)
  • Consumer electronics manufacturers (smartphones, tablets, wearables)

Application Scenario

A PCB manufacturer needs to print a serial number, date code, and micro QR code on each board in a 3 mm × 3 mm area. The S1000 CIJ Printer prints at 100 m/min with 1.2 mm character height, producing scannable micro QR codes that link to the manufacturer’s MES system. The automatic viscosity control compensates for the factory’s daily temperature swing (22–28°C) without operator intervention. The compact printhead fits between the pick-and-place machine and reflow oven without modifying the SMT line layout.

FAQ

  • Q: What is the smallest character size? A: The S1000 can print characters as small as 1.2 mm in height with sharp, legible edges.
  • Q: Can it print micro QR codes? A: Yes. The printer supports micro QR codes and high-density QR codes with high scan-read rates.
  • Q: How does it handle temperature changes? A: Automatic viscosity measurement technology adjusts ink viscosity in real time based on ambient temperature and humidity.
  • Q: Will the print survive soldering temperatures? A: Yes. SHICAI offers high-temperature-resistant ink formulations that withstand lead-free reflow soldering profiles (up to 260°C).
