Overview Manuals Specifications Application Operating Environment Monitoring and Control

Features:

  • Specifically designed to remove submicron particles from delicate surfaces such as silicon wafers, hard disks, and gallium arsenide, minimizing surface damage compared to lower-frequency alternatives
  • Utilizes a continuous flow of cleaning liquid combined with ultrasonic radiation to physically remove contaminants without mechanical abrasion, preventing particle reattachment and ensuring high cleanliness levels
  • It operates on universal AC100-240V power and includes external control I/O for seamless integration into automated semiconductor production lines
The W-357-1MPD operates at a nominal frequency of 1MHz, which is significantly higher than standard ultrasonic cleaners (typically 40kHz). Higher frequencies produce shorter wavelengths, resulting in smaller cavitation bubbles. These tiny bubbles implode with less violent energy, making them highly effective at penetrating small spaces and removing submicron particles without eroding or pitting the surface of the substrate. This makes the W-357-1MPD ideal for critical applications such as cleaning silicon wafers before vapor deposition or after CMP processing. The 40W rated output provides sufficient energy for efficient cleaning while maintaining the gentle action required for sensitive electronic components.

Traditional brush cleaning carries a high risk of generating scratches and electrostatic discharge damage. The W-357-1MPD eliminates this physical contact. It operates as a "spot-jet" system, radiating a focused stream of liquid that has been energized by 1MHz ultrasonic waves. The liquid acts as a transport medium; as the ultrasonic waves dislodge contaminants, the continuous flow immediately sweeps them away. This dynamic flow prevents the "particle reattachment" phenomenon common in tank-style dippers, where contaminants float in the bath and re-land on the product.

From an integration standpoint, the W-357-1MPD is designed to work with existing automation. It accepts a wide range of input voltages (AC100-240V) for global use and includes external drive contacts (DC24V) that allow a PLC or robot controller to turn the ultrasonic power on and off. It also features dry-run protection and alarm outputs to ensure safe operation. The system supports a fluid temperature range of 20-50°C and a flow rate of 3.5 L/min, making it adaptable to various DI water or chemical solutions.

The W-357-1MPD HONDA ELECTRONICS Power Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

Description
The W-357-1MPD is a 1MHz pulse jet ultrasonic cleaner manufactured by Honda Electronics . It operates as a spot-jet cleaning system that combines ultrasonics with a continuous flow of liquid to remove submicron particles from delicate surfaces such as wafers and hard disks. 

When using the W-357-1MPD, engineers benefit from a non-contact cleaning process that prevents particle reattachment. The unit operates at a nominal frequency of 1MHz with a rated output of 40W .

The W-357-1MPD is part of a broader lineup that includes 400kHz, 1.5MHz, and 3MHz variants, allowing users to select the appropriate frequency for their specific particle size removal needs . The system is particularly effective for post-CMP cleaning, pre-deposition cleaning, and mirror-finish surface preparation of gallium arsenide and silicon substrates.

For users requiring a reliable precision cleaning solution, the W-357-1MPD offers a proven, field-tested design. It operates on standard AC100-240V power and includes safety features like a dry-run protection code .

Technical notes
The W-357-1MPD utilizes a unique "pulse jet" method that combines 1MHz ultrasonic waves with a continuous stream of fluid. This allows the ultrasonic energy to act directly on the cleaning target while the flowing liquid acts as a transport medium, ensuring detached particles are immediately washed away and do not resettle on the surface.
