NanoClear® - Stencil Wipes

NanoClear® - Stencil Wipes Description:

High performance fluxophobic stencil treatments wipes

Enhance your stencil performance in seconds!

Aculon is pleased to announce the launch of their latest generation of stencil coating technology. Aculon’s proprietary technology treats the underside of stencils to make them fluxophobic i.e. repels flux and oils.

By using NanoClear your stencil will repel flux which means:

• Better Quality Printing
• Reduce Underside Cleaning
• No Capital Equipment
• Durable Treatment
• Apply in less than 5 Minutes
• Treat Sensitive Apertures
• Treats Aperture Walls
• Cost Effective
• Industry Proven
• Increased Print Reliability
• Reduced Paste Transfer
• Reduce Flux Bleed
• Reduce Solder Ball Transfer
• Improve First Pass Yield

Better Quality Printing:

The better quality printing is due to the reduction in bridging as the flux is now repelled from the aperture walls. Tests have shown that treated stencils show significantly reduced the cleaning cycle frequency resulting in both improved print quality and better manufacturing efficiency.

Stronger Formulation

Faster release and improved print resolution is achieved as the paste is more easily released from the aperture walls due to the Fluxophobic nature of the treatment. The Aculon NanoClear treatments are now 50% stronger due a greater concentration. As can be seen from the graph below a treated stencil is 8 times more oil repellent than an untreated stencil even after 100,000 abrasion cycles.

Fluxophobic and Abrasion Resistant

Independent testing proves that NanoClear offers best in class durable performance. The ability of a stencil treated with NanoClear far outperforms the initial performance of all competitive materials. NanoClears ability to repel flux is maintained for over 100,000 abrasion cycles after treatment while the performance of a well known vacuum applied competitive materials performance quickly falls off after 5000 abrasion cycles from an already weak barely fluxophobic starting point.

Survives Aggresive Cleaning

Testing proves that NanoClear survives stencil washing in even the most aggressive stencil washing solutions. Tests were conducts by Zestron to determine the durability of the NanoClear treatment in an aggressive stencil washing system. A treated stencil was subjected to the following tests:

• Washed in Vigon SC 210 at 15% concentration
• Washed for a total of 2400 minutes exposure (160 cycles at 15 minutes) each in a Systronic SYS 152/2 system
• Foil checked for compatibility after each wash cycle
• Rinsed with DI water
• The stencil was inspected and tested every 20-30 cycles for delamination and discoloration and repellency

The NanoClear treatment was found to be compatible with VIGON SC 210 during the above compatibility testing. There was no delamination or discoloration observed after exposure. There was minimal degredation in the fluxophobic performance of the NanoClear treatment with highly repellent Water contact angles of 110 degrees and oil contact angles of 60 degrees.
