Mechanic WQ86 50GR Sn42Bi58 lead-free solder paste is an essential consumable for soldering and desoldering work in electronics, especially suited to components sensitive to high temperatures.
Main features:
- Very low melting point: 138-140 ºC, ideal for avoiding damage to delicate components.
- Composition: lead-free Sn42/Bi58 alloy, compliant with environmental regulations.
- Approximate capacity: 50 grams, enough for multiple applications.
- Especially useful for desoldering SMD ICs and soldering LED strips that cannot withstand high temperatures.
Comparison with other solder pastes:
- WQ86 Sn42Bi58: very low melting point (138-140 ºC), ideal for delicate work and repairs.
- XG-50 Sn63/Pb37: medium melting point (185-190 ºC), traditional leaded paste, not suitable for current commercial products.
- BST-705 Sn99Cu07Ag03: high melting point (235-240 ºC), alloy used in electronic boards compliant with ROHS regulations.
Typical uses:
- Desoldering SMD components with hot air or a soldering iron, avoiding damage from excessive heat.
- Soldering LED strips and other temperature-sensitive components.
- Electronic repairs where a low melting point is required to protect the board and components.
Compatibility: Compatible with soldering stations and soldering tools that support lead-free solder paste. Not intended for mass production of commercial products due to its specialised use.
Note: The product is currently out of stock. We recommend checking alternatives or future availability for your projects.

Customer Questions & Answers
What is the main advantage of using this lead-free Sn42/Bi58 solder paste compared with traditional lead-based solder pastes?
The main advantage is its low melting point, which is 138-140 °C, much lower than traditional lead-based pastes (185-190 °C). This makes it suitable for soldering heat-sensitive components such as LED strips or SMDs, reducing the risk of thermal damage. In addition, as it contains no lead, it complies with environmental and safety regulations such as RoHS.
What exactly is included in the pack, and how much paste is there in total?
The product includes approximately 50 grams of Sn42/Bi58 solder paste in an airtight jar. No accessories or additional tools are included in the pack.
Is this paste compatible with standard soldering irons, and are there any special considerations during application?
Yes, it is compatible with standard electric soldering irons. Due to its low melting point, it is recommended to set the soldering iron power or temperature to a low value (140-160 °C) to avoid overheating the paste and the electronic component.
How long can the paste be stored without losing its properties, and are there any specific storage conditions?
Under standard conditions (sealed, room temperature 15-25 °C and low humidity), the paste retains its properties for up to 12 months. To maximise shelf life, avoid prolonged exposure to air and keep the container tightly closed when not in use.
Does this paste have any safety certification or comply with specific regulations?
As a lead-free alloy, it complies with the European RoHS (Restriction of Hazardous Substances) directive. However, it is not certified for medical or aerospace applications; it is intended for general electronics use.
What is Mechanic WQ86 Sn42Bi58 solder paste used for?
It is used for soldering and desoldering heat-sensitive electronic components, especially SMD ICs and LED strips, thanks to its very low melting point.
What is the difference between Sn42Bi58 and Sn63Pb37 solder paste?
Sn42Bi58 has a lower melting point (138ºC) and is lead-free, ideal for delicate work, while Sn63Pb37 has a medium melting point (185-190ºC) and contains lead, so it is not suitable for current commercial products.
Can I use this paste for manufacturing commercial products?
No, this paste is recommended for repairs and specialised work, not for mass production due to regulations on the use of lead-free materials.
Is the product available for immediate purchase?
The product is currently out of stock. It is recommended to check future availability or look for similar alternatives.
