This week the flux-off solder flux comparison returns. Our everyday Edsyn FL-22 goes head to head with two AMTECH syringe fluxes in the TQFP arena. Just for fun, we also tried to solder with shards from a solid rosin block. Find out which flux reigns supreme.
- Edsyn FL22, our everyday favorite syringe flux
- AMTECH “USA” NC-559-ASM-TPF(UV)
- AMTECH “China” made RMA-223
- Flakes from a solid rosin block
Special thanks to Sjaak for the AMTECH “China” flux.
