RS PRO Colophony-Free Tin/Lead Solder Wire
From the trusted RS PRO brand, this solder wire stands apart due to its colophony-free formulation, making it ideal for those who are sensitive to the rosin fumes that are traditionally found in solder flux.
The flux formulation of this solder wire is ideal for wetting common Printed Circuit Boards (PCBs) and components and leaves behind a clear residue that can be removed with dry brushing for a cleaner look or safely left on the PCB after soldering.
Feature and Benefits
• Versatile soldering wire that can be used for a wide range of soldering tasks
• Alloy used consists of 60% tin and 40% lead
• Melting point between 183-188°C
• Low odour formulation with 1.1% flux content
• Soldering iron typical tip temperature for this solder wire is 320-360°C
Applications
Solder is used alongside soldering irons, particularly in securing electrical components to integrated circuit boards. The solder melts easily when heated, and cools quickly, meaning it can be moulded to secure components in place in solder joints. The quick setting nature of solder means it can also be used for light brazing.
Because of its relatively low melting point, solder can be reworked easily by heating it to melting point and using a solder sucker to remove it.
Solder is commonly used with SMD and through-hole components, with applications in repair, prototyping and production.
What are the differences between lead-free solder and leaded solder?
Lead-free solder is generally regarded as having a more positive environmental impact than leaded solder, and also as being safer for human use. However, lead-free solder also has potential production advantages. Lead-free solder can offer better lead spacing, which makes it more suitable for high-density components where pitches are tight. This means potentially better performance where space saving is a concern.
The advantages of lead solder are that it has a lower melting point, which is sometimes preferable for hand working components. Also, lower working temperatures reduces the risk of damage to components and circuit board.
Unlike lead-free solder, lead solder does not have a shelf-life and is less prone to losing quality after prolonged exposure to oxygen. However, many electronic application requirements exclude the use of lead solder, due to the toxicity of lead.
