Vision Positioning Screen Printing Machine
Model: VAP-100
Product Overview
VAP-100 is a precision screen printer for ceramic substrates in chip resistor production. It combines dual-camera vision positioning with PC-based vision control and PLC motion control to deliver stable setup and fine alignment for miniature components.
Why Choose VAP-100
Built for stable alignment, fast setup, and controlled deployment to keep high-precision printing quality consistent in production.
Features
- The screen holder supports independent front/back, left/right, up/down, and rotation adjustments with dial indicators for easier precision setup.
- Each camera has X/Y/Z adjustment and a shared X/Y/theta platform. Micrometer-based adjustment with nine guide rails enables fine alignment with straightforward operation.
Implementation Flow
- Requirement review: confirm workpiece size, CT target, alignment tolerance, and on-site constraints.
- Solution evaluation: propose machine configuration and feasibility suggestions.
- Sample and validation: run tests based on target conditions and confirm quality goals.
- Deployment and training: deliver the machine, establish parameters, and train operators.
- Production support: optimize settings continuously based on mass-production feedback.

Use Cases
Scenario: As production shifted to 0201 parts, tolerance windows became tighter and setup time frequently slowed line changes.
Result: With VAP-100 dual-camera alignment and standardized setup flow, first-article confirmation became faster and changeovers became smoother, improving production stability.
Scenario: Frequent product switching made parameter consistency difficult to maintain.
Result: Standardized workflow and vision alignment reduced switching risk and minimized variation caused by operator experience differences.
