Automatic PCB Legend Inkjet Printer for High-Precision Printing with Direct Digital Inkjet and Inline Production Capability

An Automatic PCB Legend Inkjet Printer for Character, Barcode and QR Code Printing is an automated industrial printing system used in PCB (Printed Circuit Board) manufacturing to digitally print identification information directly onto PCB boards.

The machine uses inkjet printing technology to print PCB legends, characters, logos, serial numbers, barcodes, QR codes, DataMatrix codes, production dates, lot numbers and other traceability information with high positioning accuracy. It can be integrated with PCB production lines for automatic board loading, printing, conveying and unloading.

In PCB manufacturing, legend refers to the visible printed information on a PCB, such as:

• Component reference designators
• Text and labels
• Logos
• Symbols
• Polarity marks
• Product codes
• Identification information

Therefore, PCB Legend Inkjet Printer specifically indicates equipment for digitally printing this type of information onto the PCB.

1. High-Precision Printing
   1. Prints fine characters, logos, serial numbers, barcodes and QR codes accurately.
   2. Suitable for PCB identification and traceability.
2. Direct Digital Inkjet Printing
   1. Prints directly onto the PCB without traditional screen-making processes.
   2. Reduces preparation time when changing PCB models.
3. Fast Product Changeover
   1. Digital files can be changed through the control system.
   2. Particularly useful for factories producing many PCB models.
4. Automatic PCB Handling
   1. The machine can be integrated with automatic loading, conveying and unloading systems.
   2. Reduces manual handling and labor requirements.
5. Inline Production Capability
   1. Can be connected with other PCB manufacturing equipment to form an automated production line.
   2. Suitable for continuous PCB fabrication processes.
6. Variable Data Printing
   1. Different information can be printed on individual boards, such as:
      1. Serial numbers
      2. Production dates
      3. Batch numbers
      4. Barcodes
      5. QR codes
      6. Product codes
7. Good Traceability
   1. Printed identification information helps factories track PCB production batches and products.
   2. Useful for automotive, industrial, communications and electronics PCB production.
8. No Printing Plate Required
   1. Compared with traditional screen printing, digital inkjet printing eliminates the need to make a separate screen for every design.
   2. This can reduce setup work and material consumption.
9. Suitable for High-Mix Production
   1. Particularly useful when customers require frequent PCB design/model changes.
   2. One machine can handle different digital printing files.
10. Reduced Manual Operation
    • Automation can reduce operator involvement in PCB positioning and printing.
    • Helps improve production consistency.

The machine is mainly used in bare PCB manufacturing and PCB fabrication, particularly where automated identification and traceability are required.

Typical applications include:

• Bare PCB manufacturing
• Multilayer PCB production
• Double-sided PCB production
• HDI PCB manufacturing
• Automotive electronics
• Industrial electronics
• Communication equipment
• Consumer electronics
• Medical electronics
• Computer and server PCBs
• High-volume PCB production
