FAQ

I'm unsure of the difference in a Type 3 solder paste and a Type 4 solder paste. Are different pastes used for different surface mount component soldering?

Solder paste types are based on the solder powder carefully graded to produce a powder with a predominant particle size. A Type 3, which is probably the most common size, is used for fine-pitch components at or above 0.5 mm (0.020") pitch. It has >80% particle size of 25 - 45 um. AType 4 solder paste is typically used for fine-pitch components below 0.5 mm (0.020") pitch and is made up of >90% of 20 - 38um powder particles.
