Up until recently I have been buying solder off ebay mainly from Chinese suppliers and not had any problems.
Then I bough a 100g lead/tin reel and attempted to solder a 0.5mm pitch processor.
The solder just blobbed everywhere barely melting.
It was a disaster so tried to removed processor using hot air and not a chance, the solder wouldnt melt ! So had to bin the pcb and processor.
I thought I was just unlucky so got some lead/tin solder elsewhere and this while a bit better was far from giving me good joints. Some joints just wouldnt take and others partly took.
So bought some solder from RS Components and that worked great.
Its all well being cheap on ebay and/or from China but if it doesnt do the job its wasted money.
So its solder only from reputable dealers from now on.

For small pitch SMD the solder needs to run really well so needs a low melting point.
The processors unsolder with hot air better with low melting point solder.
Buy cheap, buy twice.
