SUMMARY

The discussion focuses on selecting appropriate solder sizes for surface mount technology (SMT) and through-hole components. Jason O recommends using Kester 0.010" solder for SMT components like MSOP, SOIC, and 0805, while Kester 0.025" solder is suitable for standard through-hole components. Participants suggest purchasing from reputable suppliers such as Digi-Key or Mouser for reliable sourcing of solder wire. The conversation highlights the importance of matching solder size to component type for optimal soldering results.

PREREQUISITES
  • Understanding of surface mount technology (SMT) components
  • Familiarity with through-hole soldering techniques
  • Knowledge of solder wire specifications, including diameter
  • Experience with soldering tools, specifically a Metcal soldering iron
NEXT STEPS
  • Research Kester solder specifications and product offerings
  • Explore soldering techniques for MSOP, SOIC, and 0805 components
  • Investigate alternative suppliers for solder wire beyond Digi-Key and Mouser
  • Learn about soldering best practices for both SMT and through-hole components
USEFUL FOR

This discussion is beneficial for electronics hobbyists, PCB designers, and anyone involved in soldering SMT and through-hole components, particularly those seeking guidance on solder selection and sourcing.

Hello All,

I'm going to be buying some solder for a used Metcal iron I won on e-Bay but I'm not sure what size solder I should get. I'm planning on doing mostly surface mount soldering of MSOP, SOIC, and 0805 sized components. I will have a few through hole components to solder (like cap leads, headers, and a few DIP sockets. What would you all recommend for solder wire sizes? Also, do any of you have any favorite sources for cheap rolls? I'm interested in getting one or two 1lb spools of it in a couple different sizes.

Thanks,
Jason O

We use Kester 0.010" solder for SMT parts (too small for regular through-hole parts), and Kester 0.025" for standard through-hole parts (too big for most SMT work). Probably just Digikey or Mouser would be an okay place to buy from. I don't know offhand if there are any cheaper places available.
 
Thanks for the tips :smile:.
