What are the signs of a faulty ignition coil in magnetron sputtering systems, and how can they be quickly diagnosed?

Ignition coil failure in MS-HS sputtering setups can lead to irregular plasma ignition, arcing, o r no ignition at all. In Pakistan, where technical diagnostics tools may be limited, what practical methods can be used to detect a failing ignition coil early? Are there voltage o r resistance tests that can be done with basic equipment?

Common signs of ignition coil failure in MS-HS sputtering systems include:

Failure to ignite plasma o r delayed ignition.

Inconsistent o r weak discharge during the sputtering process.

Audible clicking o r arcing sounds.

Burn marks o r discoloration around the coil terminals.

Quick diagnostic steps:

Use a multimeter to check the coil’s resistance consult manufacturer specs for expected values.

Inspect the coil visually for cracks, corrosion, o r loose connections.

Swap with a known good coil if available to confirm the issue.

Check the power supply output to ensure it’s within range for the ignition coil’s input.
