Cold solder joint: The surface of soldering point is not smooth resulting from the wetting is not
enough. Its feature is the surface is gray and has many holes owing to insufficient heat and
mistakenly cleaning.

Solder bump: There appears solder bumps on the surface of PCB and the solder is round

because the solder is affected by cohesion itself.

Icicle: The top of soldering point is like the icicle due to insufficient wetting between solder and

wires.
Solder flags: There appears solder flags resulting from insufficient wetting of wire.
Solderability: It means the joints’ (Joints are wire, PCB or thread) ability of wetting (Wetting
means the ability of being soldered) for strong connection.

Poor wetting: The solder does not cover the joint thoroughly and the joint is exposed in the air.

SMT: It is the abbreviation of Surface Mounted Technology, which is one of popular technology

and techniques in electronic assembly industry.

SMC: It is the abbreviation of Surface Mounted Components, which consists of rectangular
components, columnar components, compound components, and heteromorphy components.
SMD: It is the abbreviation of Surface Mounted Devices, which consists of slice-type transistor
and integrate circuit and the integrate circuit consists of SOP, SOJ, PLCC, LCCC, QFP, BGA,
CSP, FC, MCM and so on.
