Involvement:Expert (understands the inner workings) - Ownership:more than 1 month
(as stated before) My colleagues nolonger bother me for solder wire.
(as stated before) Absurd level of impurity; Even the smallest joint produced dross that needs scraping off with a hot iron.
The rosin core (if there was any) does not appear to run through the entire length of the spool.
AND the quality is so bad that I've now reached a section where different meters of the solder behave radically differently.
DIFFERENT SEGMENTS ARE OF DIFFERENT COMPOSITION!
Somehow they've made somthing with no moving parts and no load absolutely unreliable.
I have to downgrade my rating of this to reflect this discovery.
It could well be Sn63% Pb37% by weight, but by composition it is CRAP-96% Luck4% (I did by chance come across a short 3 cm bit where it performed beautifully before immeadiatly turning into hard lumpy shit.)
Flux alone can not save this.
The spool I recieved has a sticker that reads "20046003".
Perhaps other batches were not so poor.
Do not buy except as scrap or to supply people who are stealing your solder.
Product not as described.
Product not consistent in quality.
