Review on πŸ’» 63Sn/37Pb Chip Quik SMD291AX Solder Paste - No Clean Flux in 5cc Syringe (15g) by Ronald Dimatulac

Revainrating 5 out of 5

Excellent for soldering tinned copper straps on lithium ion batteries

This compound is excellent for soldering tinned copper straps on lithium ion batteries for e-bike batteries. I press it with a metal rod or screwdriver and heat it for a few seconds until it turns metallic. Apparently no problem with the isolated positive pole. I press down firmly on the sensitive center area of the negative terminal with a flat metal rod and heat each side of the tinned copper strip in turn until the molten solder flows.

Pros
  • Consistent test results
Cons
  • Socket required
