JBC C115112 Soldering Cartridge | Knife 2.5 x 0.3 | C115 Nano Series | NT115 NP115 AN115 Handle

JBC C115112 Soldering Cartridge | Knife 2.5 x 0.3 | C115 Nano Series | NT115 NP115 AN115 Handle

The JBC C115112 is a knife 2.5 x 0.3mm cartridge from the C115 Nano series — JBC’s ultra-precision cartridge platform designed for soldering and reworking the smallest components in electronics assembly, including work performed under a stereo or digital microscope. The knife geometry provides a flat, angled cutting edge ideal for drag soldering ultra-fine-pitch leads, pad touch-up, flux removal, and precision wire tacking on miniaturized assemblies. Compatible with the NT115-A Nano Handle, NP115-A Nano Tweezers, and AN115-A Adjustable Nano Tweezers. Complies with the most demanding international regulations. Lasts up to 5 times longer than competing nano tips when used with JBC’s Sleep & Hibernation system.

Key Specifications

Key Features

• Knife 2.5 x 0.3mm geometry — flat angled knife profile for drag soldering ultra-fine-pitch leads, pad clean-up, flux scraping, and precision wire tacking; the 0.3mm edge minimizes heat spread to adjacent pads on densely populated boards
• C115 Nano series — JBC’s smallest cartridge platform, engineered for ultra-precision soldering at the limits of hand assembly; ideal for 01005 and smaller passive components, fine-pitch IC leads, and nano-scale rework
• Microscope compatible — tip size and C115 handle ergonomics designed for work under stereo microscopes and digital inspection microscopes in advanced rework and repair environments
• Three handle options — compatible with NT115-A Nano Handle (single tip), NP115-A Nano Tweezers (dual tip for SMD), and AN115-A Adjustable Nano Tweezers (adjustable tip spacing for different component sizes)
• Instant heat-up and excellent heat transfer — JBC’s integrated heater/cartridge design delivers rapid thermal recovery even at nano scale, maintaining consistent tip temperature during continuous micro-soldering
• 5x longer tip life — JBC Long Life tip technology combined with Sleep & Hibernation extends C115 cartridge life up to 5x vs competing nano tips, critical for expensive specialty cartridges
• Regulatory compliant — meets demanding international regulations for electronics manufacturing materials

Frequently Asked Questions

What is the C115 Nano series and how does it differ from C210 and C245?
The C115 is JBC’s smallest cartridge platform, designed for the most demanding ultra-precision nano-scale soldering and rework. C115 cartridges are significantly smaller than C210 (precision) and C245 (general purpose) cartridges and require their own dedicated handles (NT115, NP115, AN115). C115 = nano/microscope; C210 = precision/fine-pitch; C245 = general purpose/production.

What handles is the C115112 knife cartridge compatible with?
The C115112 is compatible with three JBC nano handles: the NT115-A Nano Handle (single iron), the NP115-A Nano Tweezers (fixed dual-tip for SMD), and the AN115-A Adjustable Nano Tweezers (adjustable tip spacing). All require a compatible JBC control station. Contact MTE Solutions at 651-600-3838 to verify station compatibility.

What applications is the knife 2.5 x 0.3mm tip best suited for?
The knife geometry excels at drag soldering ultra-fine-pitch IC leads, cleaning and re-tinning pads, tacking fine magnet wire and enameled wire, flux residue removal, and precision cut-through on component leads. The flat 2.5mm face provides controlled heat distribution along a lead row; the 0.3mm edge limits heat spread between pads.

How does JBC’s Sleep & Hibernation extend life on nano cartridges like the C115112?
C115 nano cartridges are among the most delicate in JBC’s range. Oxidation at idle temperature is the primary life-limiting factor. JBC stations automatically reduce tip temperature when the handle is set down (Sleep) and drop further to hibernation after extended idle time — dramatically reducing oxidation between soldering operations. The result is up to 5x longer cartridge life vs systems without tip temperature management.

Is the C115112 compatible with lead-free soldering?
Yes — JBC C115 cartridges are suitable for both leaded (SnPb) and lead-free (SAC305 and other alloys) soldering. At nano scale, precise temperature control is especially important with lead-free alloys to avoid pad and component damage. Ensure your station is set appropriately for the alloy and component being worked.
