Often, operators use too much flux. I'd rather use flux pens because they limit the amount of flux used.

Flux can be dropped in small vials, using a sealed or refillable flux pen. Often, operators use too much flux. I'd rather use flux pens because they limit the amount of flux used. I would also prefer to use solder with a flux core, which contains flux and solder alloys. When using solder with flux core and liquid flux, ensure that the flux is compatible with each other.

Surface mount welding usually requires a small diameter tin wire, typically in the range of 0.50 to 0.75mm. Through hole welding usually requires a large diameter tin wire, ranging from 1.20 mm to 1.50mm.
The paste can also be dropped with a syringe, although many manual welding methods heat the paste too quickly, causing spillage and tin balls. Flux glue, rather than solder paste, is very useful for replacing area arrangement components.
