In context
Immediately after printing, it maintains its shape and temporarily holds components. During heating, it provides solder for metal joints and flux to assist surface reactions.
Example
The total printed paste volume is not equal to the volume of the metal joints after cooling. Some of the medium evaporates or remains as residue during heating.
Key distinction
Distinguish wet paste volume from final solder volume.
