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. Review: Very good stuff, tube will last a long time for my purposes - Excellent stuff, good value as not very much is needed and pretty easy to use or clean up. I bought this to assist with removing solder on controller pcb's so that I could do stick swaps. I do not use this for the solder to hold the new sticks in place I use 63-37. What I use this for is to add a little to the globs of factory solder to help reduce the melting point as most use non leaded these days. If you are doing it for this purpose you do not need very much a small dot and you are good. Then just a touch of heat to melt the solders together and then remove, very easy and works great. ## Features - Paste Content: Alloy Tin 42% Bi58, Sloder Flux Content: 10.5% - Product Parameters: Total Weight: 39g, Net Weight Of Paste: 30g - Paste Features: No Clean, Strong Viscosity, Bright Welding Point - Product Advantages: Pushing design for Smoother Flowing, No Waste During Welding - Applications: Widely Used In Circuit Board, IC, Phone, TV and Other Household Appliances and Industrial Equipment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BLSJQPR6 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #3,533 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #16 in Soldering Parts & Accessories | | Customer Reviews | 4.6 4.6 out of 5 stars (914) | | Date First Available | November 8, 2022 | | Item Weight | 1.76 ounces | | Item model number | SP-Sn42Bi58 | | Manufacturer | wonderway | | Material | Solder Paste | | Part Number | SP-30G-Sn42Bi58 | | Power Source | fuel_powered | | Product Dimensions | 3.73 x 1.35 x 0.92 inches | | Size | T4 30g | ## Images ![Wonderway Sn42/Bi58 T4 Lead Free Solder Paste No Clean, 138℃ Melting Point (30g) - Image 1](https://m.media-amazon.com/images/I/71V+PoyOrbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by O***C on April 7, 2026* Soldering is not something I am an expert at.

It melts smoothly and flowed nicely, which made my joints clean and easy to solder. I also like that it’s lead-free — it gives me extra peace of mind when working in shared spaces. The thickness (Sn42/Bi58) felt just right for both small and medium-sized connections. Overall, I’m very happy with this solder and would buy it again. ## 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.)
