Where should an ECG test station sit in a watch production line?

Three rules govern placement. Put it late, because ECG validates whole-unit function and belongs after assembly and the basic radio and functional tests. Keep the sequence physically sensible: run tests that can disturb electrode contact — water resistance, drop — before ECG, and finish ECG before packaging. Match the cycle time: a four-position station can run parallel or sequential output, so align it with the UPH of the stations on either side and drive fixture changeover and judgement from a recipe.

Key points

• Place ECG after assembly, radio, and basic functional tests
• Run water resistance and drop tests before ECG, because they affect electrode contact
• Finish ECG before packaging, since packaging is irreversible
• Four-position output can run parallel or sequential; align it with neighbour UPH
• Fixture changeover and judgement driven by recipe, not operator choice
