Mycronic Midas A23S Nozzle 3mm ID Spring Tool (Spring Suspended) L-012-0551B
The Mycronic Midas A23S Nozzle 3mm ID Spring Tool (Spring Suspended) L-012-0551B is a mid-to-large format precision placement nozzle for the Mycronic Midas placement head. Here's what's generally known about this part:
This is a 3mm inner diameter spring-suspended placement nozzle designated as the A23S nozzle type, designed for use with the Mycronic Midas placement head on MY-series pick-and-place machines. Sitting between the A14S (2mm) and A24S (5mm) in the Midas nozzle range, the A23S fills an important mid-to-large format role, handling a broad range of medium to larger SMT components with the enhanced compliance benefits of spring suspension.
Key characteristics typically associated with this part:
- Application: Mycronic MY-series pick-and-place machines equipped with the Midas placement head
- Function: Uses vacuum suction through the 3mm ID tip to pick up medium to larger SMT components from feeders or trays and place them precisely onto PCB pads; the spring-suspended mechanism provides controlled Z-axis compliance during placement, absorbing contact force to prevent component or PCB damage while accommodating height variations across the board surface
- Manufacturer: Mycronic (L-prefix indicates a Mycronic assembly-level part number)
- Part number: L-012-0551B (the "B" suffix denotes a specific revision level)
- Nozzle Type: A23S — Mycronic's internal nozzle classification; the "23" indicates its position in the larger format A-series range, and the "S" suffix designates the spring-suspended variant providing enhanced compliance characteristics
- Tip ID: 3mm inner diameter — provides a medium-to-large vacuum contact area bridging the gap between the 2mm A14S and 5mm A24S nozzles
- Type: Spring-suspended nozzle / compliant placement nozzle assembly
- Construction: Typically comprises a precision-machined nozzle tip (ceramic or hardened steel) with a spring-suspended shank body, providing extended compliance range, vacuum channel integrity, and controlled Z-axis force absorption
-
Spring Suspension Mechanism: Provides enhanced Z-axis compliance with greater vertical travel range than a standard spring tool, making it particularly well suited for:
- Medium to larger component bodies requiring a broader vacuum contact area
- Components with moderate height profiles needing controlled placement force
- PCBs with surface height variations requiring additional compliance tolerance
- Components too large for the A14S 2mm tip but not requiring the full 5mm contact area of the A24S
Component Size Compatibility: The 3mm ID tip with spring-suspended compliance is generally suited for components including:
- 1206, 1210, 1812 and larger chip resistors and capacitors
- Tantalum capacitors (small to medium body sizes)
- SOT-89, SOT-223, TO-252 and similar medium power packages
- Small to medium SOIC, SOP, and SSOP packages
- Small QFP and QFN packages
- Small to medium inductors and transformers
- Medium body connectors and switches
- Small oscillators and crystal packages
- Medium MLF/LCC packages
A23S Positioning in the Midas Nozzle Range: The A23S occupies a critical mid-to-large position in the Midas A-series nozzle hierarchy:
| Nozzle | Tip ID | Best For |
|---|---|---|
| A13 | 1.2mm | Small passives, SOT-23, 0402/0603 |
| A14S | 2mm | Mid passives, small ICs, SOT packages |
| A23S | 3mm | Medium-large passives, medium ICs, power packages |
| A24S | 5mm | Large ICs, QFPs, large passives, large power packages |
