RS PRO SAC305 Lead Free Solder
On July 1 2006 the RoHS restricted the use of lead based materials in the manufacturer of electronics and electronic equipment because of the health hazard of lead. The RS Pro resin-based SAC305 is a lead free, no clean solder wire that wets more readily than SnCu based solders.
Features and Benefits
• Leaves low level of clear flux residue which can be left safely on the PCB
• Wets well to all PCB and component finishes
• Ideal for all lead-free applications
• Spreads like a RA flux
• Available in different wire diameters
• Contains 3% silver
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.
Why RS PRO?
