PCB (Printed Circuit Board) screen printing machines are used to print characters, symbols, patterns, or markings on circuit boards, aiding in assembly, soldering, and identification. Common types of PCB screen printing machines include:

1. Manual Screen Printing Machine

• Suitable for small-scale production or laboratory use
• Simple operation with low cost
• Requires manual alignment and operation, lower precision

2. Semi-Automatic Screen Printing Machine

• Ideal for medium-scale production
• Offers some automation features like automatic alignment and ink scraping
• Higher precision and efficiency compared to manual machines

3. Fully Automatic Screen Printing Machine

• Designed for large-scale production
• Features automatic board feeding, alignment, printing, and drying
• High precision and efficiency, suitable for mass electronics manufacturing

4. Laser Marking Machine

• Uses laser technology to engrave markings on the PCB surface
• No need for ink, environmentally friendly and pollution-free
• High precision, suitable for intricate PCB designs

5. Stencil Screen Printing Machine

• Uses a mesh stencil to transfer ink onto the PCB
• Ideal for mass production
• Requires custom stencils, making it suitable for fixed design printing

6. Inkjet Printing Machine

• Utilizes inkjet technology for non-contact printing
• Supports variable data printing without changing stencils
• Suitable for small-batch customization and personalized production
