Introduction
Legend marking — adding component IDs, logos, dates, and alignment marks — is essential for PCB assembly, traceability, and quality. While screen printing has long been standard, it struggles with short runs, frequent design changes, and environmental regulations. Chikin Automation's PCB Inkjet Printing Machine introduces digital precision: non-contact inkjet deposition that prints legends directly from Gerber data, eliminating screens and reducing setup from hours to minutes. With high-resolution heads and advanced alignment, it delivers crisp, durable marks on FR4, flexible circuits, and metal substrates while supporting eco-friendly UV-curable inks.
Backed by our 20+ years in PCB automation, this machine integrates smoothly into drilling, routing, and SMT lines.
How the PCB Inkjet Printer Works
- File Import — Load Gerber or CAD files with legend layers.
- Fiducial Alignment — CCD cameras detect fiducials for automatic registration (±0.01–0.03mm accuracy).
- Inkjet Printing — Industrial printheads (e.g., Ricoh or Kyocera) jet UV or solvent-based ink in precise droplets.
- Curing — Inline UV lamps instantly cure ink for smudge-proof, abrasion-resistant results.
- Output — Board ready for next process; reports generated for traceability.
Chikin's models (e.g., single or dual worktable) handle sizes up to 730×630mm, with fast scan speeds for high throughput.
Advantages of PCB Legend Inkjet Printer Over Traditional Silkscreen
| Feature | PCB Inkjet Printing Machine | Traditional Silkscreen Printing |
|---|---|---|
| Setup Time | Minutes (digital file change) | Hours (screen making/exposure) |
| Tooling Cost | None | High (screens per design) |
| Flexibility | Instant design changes | Fixed per screen |
| Resolution & Detail | High (fine text, barcodes, QR codes) | Limited by mesh |
| Waste & Environment | Minimal ink waste, eco-inks | Solvent waste, screen cleaning |
| Registration Accuracy | CCD auto-alignment | Manual or semi-auto |
| Durability | Excellent (cured ink) | Good, but varies |
Inkjet excels for variable data, prototypes-to-mid-volume, and compliance with RoHS/green standards.
