Wonderway Sn63/Pb37 T4 Tin Lead Solder Paste 183°C – No-Clean, 30g x 4 Packs

Overview

Wonderway Sn63/Pb37 T4 Tin Lead Solder Paste is formulated for electronics assembly where dependable joints and clean workflow matter. The alloy combines Tin at 63% with Lead at 37%, paired with a flux content around 10.5% to support smooth deposition and reliable wetting. Packaged as four convenient 30 g pastes (totaling 39 g per set), it suits both small production runs and hobbyist or prototyping tasks. With a melting point near 183°C, the paste reflows at common temperature profiles, producing bright, consistent welds. Its No-Clean formulation minimizes post-solder cleanup, helping you focus on assembly rather than cleanup. The result is a paste designed for smoother flow and reduced waste during welding, offering a practical balance of performance and convenience for everyday electronics work.

Key features

• No-Clean flux reduces cleanup time after soldering.
• Strong viscosity supports stable deposition and controlled spread.
• Bright welding points help indicate solid, reliable joints.
• Engineered for smooth flow to minimize gaps and overspill.
• Four 30 g paste packs provide a practical working volume (39 g total).
• 183°C melting point aligns with common reflow profiles for electronics projects.

Ideal use cases

• Prototyping and small-batch PCB assembly where clean joints matter.
• Repair or rework on densely populated boards with tight component spacing.
• Hobbyist projects that require precise paste placement and good wetting.
• General surface mount and through-hole soldering tasks requiring reliable flow.

Usage tips and safety

Apply small amounts to joints with appropriate tools, working in a well-ventilated area. Store the paste sealed and away from heat. Note that this product contains lead; follow California Prop 65 guidance and local safety regulations. Responsible handling and disposal help ensure safe, repeatable results across projects.
