Helium Leak Testing for Laser-Welded Hermetic Packages
Select the helium test mode, define package volume and timing, control calibration, and combine fine-leak measurement with an appropriate gross-leak screen. Compare gross- and fine-leak testing to understand coverage, tracer loss and conflicting test results.
Before comparing a detector reading with the drawing, check leak-rate units and acceptance criteria, including gas, reference conditions and the required decision rule.
