Fuji NXT SMT Machine Nozzle Selection Guide

In surface-mount technology (SMT) manufacturing, the productivity of pick-and-place machines can be significantly compromised by what might seem like a minor component: the nozzle. The selection of an appropriate nozzle is critical for ensuring both placement accuracy and speed. This article provides a detailed analysis of nozzle specifications for Fuji's NXT series SMT placement machines and offers practical selection guidance to optimize production workflows.

The Fuji NXT series of placement machines are renowned for their high precision and flexibility, with nozzles serving as core components that directly influence placement quality. Below is a comprehensive breakdown of commonly used nozzle models for Fuji NXT machines:

The H08 series represents one of the most widely used nozzle families for Fuji NXT machines, suitable for picking and placing various component types. This series offers diverse specifications to accommodate components ranging from small chips to larger elements.

• AA05600 (H0812 Yellow Φ0.45/0.3): Designed for extremely small components, with yellow identification marking.
• AA05700 (H08 Blue Φ0.7/0.5): Suitable for small components, with blue marking.
• AA05800 (H08 Pink Φ1.0): For medium-sized components, with pink marking.
• AA20A00 (H08 Green Φ1.3): For slightly larger components, with green marking.
• AA06400 (H08 Orange Φ1.3 Melf): Specifically designed for MELF package components, with orange marking.
• AA20B00 (H08 Aqua Φ1.8): For larger components, with aqua marking.
• AA19G00 (H08 Orange Φ1.8 Melf): MELF package specific, with orange marking.
• AA20C00 (H08 Purple Φ2.5): For relatively large components, with purple marking.
• AA06504 (H08 Orange Φ2.5 Melf(R07-025M-070)): Designed for specific MELF package specifications, with orange marking.
• AA0WT00 (H08 Purple Φ2.5G): For large components, with purple marking and potential special coating.
• AA20D00 (H08 Yellow-Green Φ3.7): For large components, with yellow-green marking.
• AA18C00 (H08 Yellow-Green Φ3.7G): For large components, with yellow-green marking and potential special treatment.
• AA20E00 (H08 Medium purple Φ5.0): For very large components, with medium purple marking.
• AA06300 (H08 Red Φ5.0G): For very large components, with red marking and potential special coating.

The H04 series represents another commonly used nozzle family for Fuji NXT machines, with design variations from the H08 series to accommodate specific component types or placement requirements.

• AA06W00 (H04 Pink Φ1.0): For medium-sized components, with pink marking.
• AA06X00 (H04 Green Φ1.3): For slightly larger components, with green marking.
• AA06Y00 (H04 Aqua Φ1.8): For larger components, with aqua marking.
• AA22Z14 (H04 Orange Φ1.8 Melf): MELF package specific, with orange marking.
• AA06Z00 (H04 Purple Φ2.5): For relatively large components, with purple marking.
• AA07F00 (H04 Purple Φ2.5G): For large components, with purple marking and potential special coating.
• AA07A00 (H04 Yellow-Green Φ3.7): For large components, with yellow-green marking.
• AA07G00 (H04 Yellow-Green Φ3.7G): For large components, with yellow-green marking and potential special treatment.
• AA07B00 (H04 Medium purple Φ5.0): For very large components, with medium purple marking.
• AA07H00 (H04 Red Φ5.0G): For very large components, with red marking and potential special coating.
• AA07C00 (H04 Medium purple Φ7.0): For extremely large components, with medium purple marking.
• AA07K00 (H04 Dark Red Φ7.0G): For extremely large components, with dark red marking and potential special treatment.

Beyond the H08 and H04 series, additional nozzle types such as H12, H01, and specialized models like TK912 exist to meet various placement requirements. The H12 series, for instance, may be appropriate for larger or heavier components.

1. Component Size and Package Type: This represents the primary consideration when selecting nozzles. Different component sizes and package types require corresponding nozzle specifications to ensure stable picking and placement accuracy. MELF package components, for example, necessitate specially designed MELF nozzles.
2. Nozzle Material and Coating: The material and coating of nozzles affect both durability and suction capability. Certain nozzles incorporate special coatings to enhance suction or reduce electrostatic effects.
3. Nozzle Maintenance and Replacement: Regular cleaning and inspection of nozzles, along with timely replacement of worn or damaged units, helps maintain placement quality and production efficiency.
4. Supplier Selection: Choosing reputable suppliers with substantial experience ensures nozzle quality and after-sales support.
5. Compatibility Verification: Before bulk purchasing, conducting compatibility tests to confirm that selected nozzles work perfectly with both Fuji NXT machines and components is essential.
