No-Clean flux leaves a benign, non-conductive residue that does not require removal. Water-Soluble flux is more aggressive for difficult joints but must be thoroughly cleaned with water to prevent corrosion.
Solder Component Intelligence
Select the right alloy and flux chemistry for reliable PCB assembly and rework.
What are Solder components?
Solder selection hinges on alloy composition (e.g., SAC305 for RoHS, Sn63/Pb37 for legacy), flux core activity, and wire diameter. Match the alloy to your thermal profile and regulatory requirements, ensuring the flux type aligns with your post-soldering cleaning process.
How to Choose Solder Components
Selecting the correct solder wire requires balancing thermal requirements, regulatory compliance, and assembly process constraints.
Alloy Composition
Choose lead-free (SAC305) for RoHS compliance or Sn63/Pb37 for high-reliability, lower-temperature legacy applications.
Flux Core Activity
Select No-Clean for minimal residue, Water-Soluble for aggressive cleaning, or Rosin-Activated for oxidized surfaces.
Wire Diameter
Match diameter to joint size: 0.3mm-0.5mm for fine-pitch SMT, 0.8mm-1.0mm for general through-hole work.
Thermal Profile
Ensure the alloy's melting point is compatible with your soldering iron's temperature range and the PCB's thermal sensitivity.
Compliance Standards
Verify that the alloy and flux meet specific industry standards like IPC-J-STD-004 for flux and J-STD-006 for alloys.
