Introduction to Panasonic Nozzles: Precision and Reliability in Fluid Dispensing
Panasonic nozzles are high-precision components designed for advanced automated fluid dispensing systems. Primarily used in conjunction with Panasonic’s own dispensing robots and platforms, these nozzles are engineered to meet the rigorous demands of modern manufacturing, particularly in electronics assembly, semiconductor packaging, and medical device production.
The core philosophy behind Panasonic’s nozzle design is to ensure unparalleled accuracy, repeatability, and process stability for applying adhesives, solder paste, lubricants, and other critical fluids.
Key Features and Strengths
-
Ultra-Precision Machining:
Panasonic nozzles are manufactured with micron-level precision. This ensures consistent fluid volume and dot/shape definition, which is crucial for applications like underfilling, die attach, and precise dot dispensing on miniaturized PCB components. -
Minimized Dripping and Stringing:
The design and surface treatment of these nozzles are optimized to prevent unwanted dripping or stringing of fluid after dispensing. This maintains a clean process, reduces waste, and prevents defects on the product. -
Wide Range of Configurations:
Panasonic offers a comprehensive portfolio of nozzles to suit various applications:-
Tapered Nozzles: For general-purpose dispensing and accessing confined spaces.
-
Teflon-Coated Nozzles: Ideal for UV-curing or fast-curing adhesives that might clog a standard metal nozzle.
-
Angled Nozzles: Designed to dispense at an angle for specific geometries or hard-to-reach areas.
-
Specialized Tips: Including needle-style tips for very fine dots and flat-end tips for specific contact dispensing techniques.
-
-
Material Compatibility:
Made from high-grade stainless steel or specialized plastics, Panasonic nozzles are compatible with a vast range of chemicals, solvents, and abrasive materials like solder paste without degrading. -
Seamless System Integration:
While they can be adapted, Panasonic nozzles are designed to work flawlessly with Panasonic dispensing systems. This ensures optimal performance, easy calibration, and reliable communication with the controller for pressure and vacuum control.
Primary Applications
Panasonic nozzles are indispensable in industries where precision is non-negotiable:
-
SMT (Surface-Mount Technology): Dispensing solder paste for fine-pitch components.
-
Semiconductor Packaging: For underfilling chips, die attachment, and encapsulation.
-
Medical Device Manufacturing: Applying biocompatible adhesives and lubricants in tiny, precise amounts.
-
Automotive Electronics: Sealing and potting electronic control units (ECUs).
-
Precision Assembly: Bonding small parts in consumer electronics and optics.
Conclusion
In summary, the Panasonic nozzle is more than just a simple component; it is a critical element of a high-performance dispensing system. Its commitment to precision engineering, reliability, and a versatile design portfolio makes it a trusted choice for manufacturers worldwide who seek to enhance their production quality, efficiency, and yield in the most demanding micro-dispensing applications.

N400A Standard nozzle, flat tip, 4.00mm inner diameter Larger components, such as electrolytic capacitors
2. Spring-loaded/Anti-collision nozzle
The nozzle has an internal spring that provides cushioning during placement, preventing damage to components or PCBs. This is especially important for delicate and odd-shaped components.
Nozzle Model Description Typical Applications
N085AZ Spring-loaded nozzle, 0.85mm ID, 0402 components (high precision requirements)
N110AZ Spring-loaded nozzle, 1.10mm ID, 0603 components (high precision requirements)
N140AZ Spring-loaded nozzle, 1.40mm ID, 0805 components (high precision requirements)
N200AZ Spring-loaded nozzle, 2.00mm ID, QFP, SOP, connectors
N250AZ Spring-loaded nozzle, 2.50mm ID, QFP, connectors, shielded cases
N400AZ Spring-loaded nozzle, 4.00mm ID, larger/heavy components
3. J-shaped/Notch Nozzle
This nozzle has a circular groove at the tip, specifically designed for picking up cylindrical MELF components.
Nozzle Model Description Typical Applications
N110J J-shaped nozzle, 1.10mm inner diameter Small MELF components (e.g., diodes)
N140J J-shaped nozzle, 1.40mm inner diameter Standard MELF components
N200J J-shaped nozzle, 2.00mm inner diameter Larger MELF components
4. Conical Nozzle
The nozzle has a conical tip, designed for picking up irregular or unusually shaped components and aids centering during picking.
Nozzle Model Description Typical Applications
N200C Conical nozzle, 2.00mm inner diameter Odd-shaped connectors, tactile switches
N250C Conical nozzle, 2.50mm inner diameter Odd-shaped connectors, coils
5. Special/Custom Nozzles

N800A Extra Large Inner Diameter Flat Tip Nozzle Very Large Components
H Series Nozzles High Hardness Materials (such as Ceramic) Used in Environments Requiring High Wear Resistance
G Series Nozzles Anti-Static Materials ESD-Sensitive Components
Panasonic Nozzle Series Classifications
N Series: Standard nozzle, most commonly used.
H Series: High Hardness, High Wear Resistance Nozzle with Longer Life.
G Series: Anti-Static Nozzle, used for ESD-Sensitive Components.
A Series: Commonly found in some older machine models (such as the CM Series), with similar functionality to the N Series.
How to Choose the Right Nozzle
When selecting a nozzle, consider the following key factors:
Component Size: The nozzle inner diameter should be approximately 50% to 80% of the component width (or smaller dimension).
Component Weight: Heavier components require a larger inner diameter to generate adequate vacuum.
Component Shape:
Chip components: Use a flat-tip nozzle (Type A).
MELF components: Must use a J-shaped nozzle (Type J).
Irregular/special-shaped components: Consider using a conical nozzle (Type C) or a special nozzle (Type S).
Component Precision and Fragility: For delicate components such as QFPs and BGAs, a spring-loaded nozzle (Type Z) is strongly recommended to prevent damage.
Placement Machine Model: Ensure the nozzle is fully compatible with your Panasonic placement machine model (e.g., NPM-D3, CM602, KME, etc.).
Important Note:
This list covers the most common models, but is not exhaustive. Panasonic also offers many other special-purpose nozzles. For the most accurate and up-to-date information, always refer to the official Parts Manual or Nozzle Selection Guide for your specific Panasonic placement machine model.
