Let customers speak for us
This company is on top of their game. Good prices, huge selection, great communication.
63/37, the best, why would you use anything else. 44 (RA) preps surfaces and works great on old circuit boards. I find .025 a good diameter for through hole or sometimes larger SMD. -IPC certified tech for 10 years
Excellent for hand soldering. Heats to liquid state quickly, and more importantly transitions from liquid to solid state extremely quickly. Finished joint is even and shiny, and needs no/little rosin cleanup. Highly recommended.
