Tinandlead (Sn 62) Solder Paste

Introduction

Sn62 Solder Paste is a Halide Free, No Clean Solder Paste & RMA Type; formulated to leave completely invisible residue of the flux. This product has a superior wetting capabilities. The paste can be used in both Stencil Design and Printer Operation.

Alloy

BT Uses Low Oxide spherical powder composed of Sn/Pb/Ag in a standard type - III Mesh Size.  The weight ratio of the flux to solder powder is referred to as the metal load typically in the range of 88-92% for standard alloy. 

Storage And Handling

Refrigerated storage will prolong the shelf life of Solder Paste. The shelf life of the paste is 6 months. Solder Paste should be allowed to reach ambient working temperature prior to use. Generally paste should be removed from refrigeration at least 2 hrs before use. 

Re-Flow

This profile is designed for use with Sn62/Pb36/Ag2. It will serve as general guideline in establishing a re-flow profile. Adjustments to this profile may be necessary based on specific process requirements.
