Test system for ionic contamination

A system for determining a presence of contaminants and electrical properties of a component on a printed circuit board (PCB), the system comprising:

• a fluid inlet operatively coupled with a fluid source;
• a fluid outlet operatively coupled with a fluid analyzer;
• first and second vacuum inlets, the first and second vacuum inlets being operatively coupled with a vacuum source;
• a snorkel comprising:
• a flexible housing having a plurality of ribs, each rib of the plurality of ribs being configured to move between a first position and a second position;
• a fluid inlet port adjacent a distal end of the fluid inlet;
• a fluid outlet port adjacent the fluid outlet;
• a first flexible seal defining a fluid boundary, wherein the fluid inlet port and the fluid outlet port define a fluid channel within the fluid boundary;
• a second flexible seal defining a vacuum boundary, wherein the first flexible seal is disposed within the vacuum boundary such that the fluid boundary is disposed within the vacuum boundary;
• and
• a plurality of electrical probes, wherein a tip of each electrical probe of the plurality of electrical probes is disposed within the fluid channel and at least one of the electrical probes of the plurality of electrical probes is adjustable, wherein the tips of each electrical probes are used to determine a resistance in fluid within the fluid channel, the resistance correlating to the presence of contaminants.
