In today’s high-mix, high-reliability manufacturing environments, non-contact solder paste jetting offers a distinct edge. Whether you’re producing prototypes, fine-pitch assemblies, or working with varied board topographies, the right combination of equipment and solder paste is essential. That’s why more manufacturers are turning to AIM NC257MD Solder Paste and MYCRONIC Jet Printers for next-generation results.

Meet NC257MD: Optimized for Jetting Precision

AIM NC257MD is a jetting-optimized, no-clean solder paste that’s available in both lead-based (Sn63/Pb37) and lead-free (SAC305) formulations — giving you flexibility to meet a wide range of application and regulatory requirements.

Whether you're working in a leaded aerospace application or RoHS-compliant consumer electronics, NC257MD delivers:

✅ Consistent Dot Formation

Engineered specifically for non-contact jetting, NC257MD forms repeatable, uniform dots without satellite formation — even during extended production cycles.

✅ Superior Wetting & Adhesion

With excellent wetting characteristics on a variety of surface finishes, NC257MD promotes strong, reliable solder joints and reduces the chance of opens or cold joints.

✅ Wide Process Window

Whether you're jetting at high or low temperatures, NC257MD offers stable performance with minimal adjustments — perfect for environments with changing variables or mixed component profiles.

✅ No-Clean, RoHS-Ready

NC257MD leaves behind a clear, benign residue that doesn’t require cleaning. The SAC305 version is fully RoHS compliant, while the Sn63/Pb37 version supports high-reliability, leaded applications where regulations allow.

Comparing NC257MD to Other Jetting Pastes

Feature	AIM NC257MD	Standard Jet Pastes
Jetting Consistency	✅ High-precision dots with no satellites	❌ Varies; prone to clogging or misfires
Process Range	✅ Broad temperature and speed tolerance	❌ Often sensitive to settings
Residue	✅ Minimal, safe no-clean residue	❌ May require cleaning or leave flux build-up
Availability	✅ Lead & Lead-Free options	❌ Limited material choices
Compatibility	✅ Tuned for MYCRONIC	❌ May require printer adjustments

Why MYCRONIC Jet Printers Lead the Industry

MYCRONIC MYJet Printers are the preferred choice for cutting-edge, stencil-free solder paste application. They’re designed to deliver fast, flexible, and accurate deposition, ideal for low-volume high-mix or high-value applications like medical, aerospace, automotive, and industrial electronics.

Key Benefits:

• No stencils = faster changeovers
• Jet-on-the-fly technology for high speed and accuracy
• Ideal for rapid prototyping and NPI
• Adaptable to warped, 3D, and densely populated boards

When combined with AIM NC257MD, MYCRONIC printers offer one of the most reliable and versatile solutions available for today’s electronics manufacturers.
