Product description
The Mechanic XG-Z40 solder paste syringe (10CC - 30GR) is an essential consumable for electronic soldering, offering a leaded solder paste made from the Sn63/Pb37 alloy. This paste is widely used for repairs and soldering projects, especially on electronic components and printed circuit boards.
Main features:
- Leaded solder paste (Sn63/Pb37).
- Approximate capacity of 30 grams.
- Syringe format for precise and convenient application.
- Medium melting point between 185-190 °C, ideal for traditional soldering.
Differences between solder paste types:
- WQ86-50GR-Sn42Bi58: Very low melting point (138-140 °C), used for desoldering SMD ICs and components sensitive to high temperatures.
- XG-50 Sn63/Pb37 (10CC - 42GR): Medium melting point (185-190 °C), the most common paste for traditional soldering.
- BST-705 sn99cu07ag03: High melting point (235-240 °C), alloy used in electronic boards that comply with ROHS regulations.
Typical uses:
- Repair of electronic boards and SMD components.
- Soldering LED strips and other electronic devices.
- Electronics projects that require traditional solder.
Compatibility and recommendations:
The Mechanic XG-Z40 solder paste contains lead, so it is not recommended for the manufacture of commercial products due to legal restrictions. However, it is ideal for repairs, prototypes and personal use. For products that must comply with ROHS regulations, lead-free alloys such as BST-705 are recommended.
How to use:
- Apply the paste to the area to be soldered with the syringe for precise distribution.
- Heat with a soldering iron or soldering station until the paste melts and a solid joint is formed.
- Allow to cool to set the solder.
This syringe makes controlled application easier and reduces material waste, making it a practical tool for professionals and electronics hobbyists.
- Leaded Sn63/Pb37 solder paste for traditional soldering
- Approximate 30-gram capacity in syringe format
- Medium melting point between 185-190 °C for efficient soldering
- Ideal for electronics repairs and projects
- Not suitable for commercial manufacturing because it contains lead
Customer Questions & Answers
What is the exact composition of Mechanic XG-Z40 solder paste, and what benefits does its Sn63/Pb37 formula offer?
Mechanic XG-Z40 solder paste contains an alloy made up of 63% Sn (tin) and 37% Pb (lead). The main benefit of this formula is its medium melting point (185-190 °C), which makes soldering easier for repairs and prototyping, offering good wetting and helping to prevent micro-cracks, although it is not suitable for products intended for sale due to environmental restrictions (RoHS).
What is the practical difference between using XG-Z40 and a lead-free solder paste such as BST-705?
The main difference is regulatory and thermal: XG-Z40 contains lead and has a lower melting point (185-190 °C), making hand soldering easier and reducing thermal stress. BST-705 is lead-free (Sn99Cu0.7Ag0.3), RoHS-compliant, but requires higher temperatures (235-240 °C), which can make work on sensitive components more difficult.
What storage care and shelf life does Mechanic XG-Z40 solder paste have to ensure performance?
To keep XG-Z40 paste in optimum condition, it should be stored at temperatures between 0-10 °C and away from direct sunlight. Under these conditions, the typical shelf life is 6-12 months after opening. Exposure to heat or moisture can degrade its properties and make soldering more difficult.
Is any special equipment or process needed to apply XG-Z40 on SMD, and what common mistakes should be avoided?
No special equipment is required; it can be applied manually with the syringe onto SMD pads before hot-air soldering or soldering iron work. Common mistakes to avoid are applying too much paste (which can cause bridges), not cleaning residue after soldering, and soldering at temperatures below 185 °C, which reduces reliable joints.
What is the Mechanic XG-Z40 solder paste syringe used for?
It is used for soldering electronic components, especially in repairs and projects that require traditional solder.
Does it contain leaded solder?
Yes, the Mechanic XG-Z40 solder paste contains lead in the Sn63/Pb37 alloy.
Is it suitable for making commercial products?
No, because it contains lead, it is not recommended for commercial products subject to regulations such as ROHS.
What is the melting point of this solder paste?
The melting point is medium, between 185 and 190 degrees Celsius.
How is the solder paste from the syringe applied?
It is applied directly with the syringe onto the area to be soldered and then melted with a soldering iron or soldering station.
