Review: Low melt point is perfect for sensitive components, clean joints every time - The low 138C melting point is genuinely useful for soldering heat-sensitive components. I have used this on several PCB rework jobs where I could not risk overheating nearby parts. The paste flows cleanly and produces bright, shiny joints without much residue. The no-clean formula means you can leave it in place without worrying about corrosion. The T4 grind is a good size for most SMD work. One tip: replace the plunger cap after each use to keep the paste from drying out. Overall a quality solder paste at a fair price. Review: Excellent! - Worked great, the low melt temp really makes it easy to work with using hot air. Got some excellent solder joints with low effort on even the smallest SMD components i was testing with. It is fumes and mess free for zero cleanup and you don't need much at all to get a good solder joint. Very impressed and glad i went with this one. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful if inhaled. - Harmful if swallowed. - May cause an allergic skin reaction. - May cause respiratory irritation. - Suspected of causing cancer. - Suspected of damaging fertility or the unborn child. - Very toxic to aquatic life with long lasting effects. - Paste Content: Alloy Tin 42% Bi58% , Sloder Flux Content: 10.5% - Product Parameters: Total Weight: 29g, Net Weight Of Paste: 20g - Paste Features: No Clean, Strong Viscosity, Bright Welding Point ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BLSJQPR6 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 665,180 in DIY & Tools ( See Top 100 in DIY & Tools ) 479 in Solder | | Customer Reviews | 4.6 4.6 out of 5 stars (1,044) | | Date First Available | 19 Jan. 2023 | | Guaranteed software updates until | unknown | | Included Components | solder paste | | Item Weight | 50 g | | Item model number | SP-Sn42Bi58 | | Manufacturer | wonderway | | Material | 30g | | Part Number | SP-30G-Sn42Bi58 | | Power Source | fuel_powered | | Product Dimensions | 9.47 x 3.43 x 2.34 cm; 50 g | | Size | T4 30g | ## Images ![Sn42/Bi58 T4 Lead Free Solder Paste（30g） - Image 1](https://m.media-amazon.com/images/I/71V+PoyOrbL.jpg) ![Sn42/Bi58 T4 Lead Free Solder Paste（30g） - Image 2](https://m.media-amazon.com/images/I/710gjNKOZwL.jpg) ![Sn42/Bi58 T4 Lead Free Solder Paste（30g） - Image 3](https://m.media-amazon.com/images/I/713a6PIcX+L.jpg) ![Sn42/Bi58 T4 Lead Free Solder Paste（30g） - Image 4](https://m.media-amazon.com/images/I/81lS3LKiL7L.jpg) ![Sn42/Bi58 T4 Lead Free Solder Paste（30g） - Image 5](https://m.media-amazon.com/images/I/81kkv3rxdpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Low melt point is perfect for sensitive components, clean joints every time *by G***S on 5 May 2026* The low 138C melting point is genuinely useful for soldering heat-sensitive components.

Got some excellent solder joints with low effort on even the smallest SMD components i was testing with. It is fumes and mess free for zero cleanup and you don't need much at all to get a good solder joint. Very impressed and glad i went with this one. ### ⭐⭐⭐⭐⭐ Good product *by O***C on 7 April 2026* Soldering is not something I am an expert at. This made repairing a ring quite simple. I found if remove the plunger and need and place the caps back on the syringe after use, the solder does not dry out. I have used it several times over the past month and it is still workable. The solder is quite versatile and a good product for the money. ## Frequently Bought Together - Wonderway Sn42/Bi58 T4 Lead Free Solder Paste No Clean, 138℃ Melting Point (30g) - Liquid Solder Flux Dropper (30 ml/1 Oz.)
