The YSHODGU flux listing, bullet by bullet

Five bullets: a rosin paste that stabilises joints and fights oxidation; two 10 g metal tins; less residue, good wetting, bright joints and little smoke; high tack for phones, motherboards, wiring and boards, and for SMT, LED and BGA; and steps to wipe, apply and solder.

YSHODGU in small tins

Ten grams twice. Paste flux goes a long way on small repairs; two tins means one can stay at the bench and one in a kit.

What YSHODGU does not classify

No activity level, flux class or residue standard. “No-clean” comes from the title; the bullets say less residue. The tins in the product photograph are labelled ZJ-18, the same label as the LABUYI and BOJACK pastes on this site.
