Partial submersion testing for plating defects

A computer program product for detecting defects on a plated-through hole using a fluid bath, the computer program product comprising a computer readable storage medium having program instruction embodied therewith, wherein the program instructions:

• submerge, partially, a first side of a printed circuit board into a fluid bath to allow for capillary fluid to partially fill a plated-through hole on the printed circuit board;
• measure a first meniscus height of the capillary fluid in the plated-through hole;
• and
• compare the first meniscus height with a calibrated height to determine a quality of the plated-through hole.

A system, comprising:

• a processor;
• a memory to store instruction, which when executed from the memory, cause the processor to perform operations,
• submerge, partially, a first side of a printed circuit board into a fluid bath to allow for capillary fluid to partially fill a plated-through hole on the printed circuit board;
• measure a first meniscus height of the capillary fluid in the plated-through hole;
• and
• compare the first meniscus height with a calibrated height to determine a quality of the plated-through hole.
