BST-705 lead-free solder paste (30gr tin)
The BST-705 solder paste is a professional solution for electronics soldering jobs that need to comply with ROHS regulations, avoiding the use of lead. This paste is made from an Sn99cu07ag03 alloy, which offers a high melting point of between 235 and 240 ºC, suitable for soldering modern electronic boards.
Main features:
- Lead-free solder paste, environmentally friendly.
- Sn99cu07ag03 alloy that complies with ROHS regulations.
- Tin capacity: 30 grams.
- High melting point: 235-240 ºC, ideal for durable and resistant solder joints.
Differences between types of solder paste:
- WQ86-50GR-Sn42Bi58: Very low melting point (138-140 ºC). Used for desoldering SMD integrated circuits and components sensitive to high temperatures, such as LED strips.
- XG-50 Sn63/Pb37: Medium melting point (185-190 ºC). Traditional leaded solder, common for repairs, but not suitable for commercial products due to legal restrictions.
- BST-705 Sn99Cu07Ag03: Lead-free paste with a high melting point (235-240 ºC). Used in the manufacture of current electronic boards to comply with environmental regulations.
Typical uses:
- Soldering electronic boards that require ROHS compliance.
- Manufacture and repair of electronic devices without the use of lead.
- Projects that demand high-quality solder joints and thermal resistance.
Compatibility: Compatible with most soldering stations and tools for soldering and desoldering electronic components. It is not recommended for simple repairs where a lower melting point would be preferable.
BST-705 paste is ideal for professionals and hobbyists looking for reliable lead-free soldering that complies with current environmental regulations. Its high melting point ensures a solid and durable bond on modern electronic boards.

Customer Questions & Answers
What are the dimensions and weight of the jar, and how much paste does each container actually hold?
The jar contains 30 grams net of solder paste. Its external dimensions may vary by batch, but they are typically around 40 mm in diameter and 35 mm in height. The net amount of paste is certified by the manufacturer, although it may vary by ±2% due to filling tolerance.
What safety and storage precautions should I follow when handling this lead-free paste?
When handling BST-705, it is advisable to wear gloves and avoid direct contact with the skin. It should be stored in a cool, dry place (15–25°C), with the container tightly closed to prevent oxidation and moisture ingress. Although it does not contain lead, it is still important to avoid ingestion or inhalation of fumes during use (ensure the work area is well ventilated). Please refer to the safety data sheet for more details.
What is the composition of BST-705 solder paste?
BST-705 paste is made from the Sn99cu07ag03 alloy, a lead-free मिश्रण that complies with ROHS regulations.
What is this solder paste recommended for?
It is recommended for soldering modern electronic boards that require lead-free soldering and high thermal resistance.
What is the melting point of this solder paste?
The melting point of BST-705 paste is high, between 235 and 240 degrees Celsius.
