01

If the Pick-and-Place machine is the brain of the SMT line, the Nozzle is its hand. Despite being small, the nozzle is a high-precision tool that directly touches every component. Choosing the right nozzle is the difference between a perfect board and a costly production failure.

1. How It Works: The Power of Vacuum

02

An SMT nozzle uses vacuum suction to pick up components from the feeder and hold them securely until they are placed on the PCB. A perfect seal is required; even a microscopic gap can cause a "component fly" (where the part drops) or "tombstoning" (where the part stands upright on the board).

2. Material Matters: From Steel to Ceramics

03

Different components require different nozzle materials:

Tungsten Steel: Durable and common for standard resistors and capacitors.

04

Ceramic: Anti-static and highly resistant to wear, ideal for sensitive ICs.

Diamond-Coated: Used for ultra-high-speed lines to prevent the nozzle tip from deforming over millions of cycles.

05

Rubber/Plastic Tips: Soft-touch tips used for delicate or oddly shaped components like connectors and LEDs to prevent surface damage.

3. Maintenance: The Key to "Zero-Defect" Production

06

Nozzles are consumable items, but their lifespan depends on care.

Clogging: Solder paste and dust can block the vacuum hole.

07

Reflection Issues: If the nozzle tip becomes dirty or worn, the machine’s vision system may fail to recognize the component, leading to frequent machine stops.

Automated Cleaning: We utilize ultrasonic cleaning and automated inspection to ensure every nozzle in our facility meets 100% performance standards before a shift begins.
