KappEE™ Tin-Lead-Silver formula is a very cost-effective eutectic electrical/electronic solder where Lead is permissible. Silver content increases strength and vibration resistance of the joint in higher stress applications. KappEE’s lower application temperature (354°F/179°C) uses less energy and requires less time and post-production cleanup, often requiring only inspection. It also eliminates the effects of high heat used in higher temperature brazing – avoiding electronic material degradation, base metal deformation, discoloration, segregation, annealment, and heat related oxide-scale formation.
KappEE™ is available in both solid wire and as a rosin-core solder for extremely fast electrical/electronic soldering. KappEER™ contains a natural mild rosin core for use on delicate electronic joints. The flux residue can be removed with warm water and a clean rag.
KappEE™ meets specification ASTM B32, Grade Sn62, QQS571.
Benefits & Features
- Low melting temperature (355°F/179°C) means less chance of heat damage to surrounding parts and circuit boards
- Instant setting helps reduce cold solder joints
- Silver content provides high conductivity
- Excellent tensile and shear strength, up to 25% stronger than 60Tin/40Lead solder
- KappEER’s non-corrosive, non-charring rosin flux core cleans like an acid flux but does not damage delicate printed circuit board traces
Applications
- High vibration electrical connections
- Sensitive electronic components and circuit chips
- Battery cables and terminals
- Large terminal lugs
- Hard-to-solder materials
- This alloy is NOT recommended for food or potable water applications. Please see KappFree™, KappZapp™, and/or KappAloy™ for Food Safe and Potable Water Applications.
Properties
The following chart contains typical physical properties for KappEE™ solder joints. *Strength values are for an average joint on Copper to Copper, and are general guidelines when selecting solder for a particular application. Many factors, such as materials, temperature, and method of application determine the end result. Call Kapp Engineering Assistance to discuss your specific needs. We recommend testing appropriate alloys in your specific application to ensure suitability. Samples of Kapp’s alloys are always available upon request.
