Why do ignition coils in MS-HS sputtering systems frequently fail in Pakistan’s high-temperature environments?

In many parts of Pakistan, especially during the summer months, ambient temperatures can exceed 40°C. This excessive heat can cause premature failure of ignition coils in MS-HS sputtering systems due to thermal stress. What cooling o r protective measures can be taken to extend ignition coil lifespan in such extreme conditions?

High ambient temperatures in regions like Punjab and Sindh often lead to overheating of electrical components, including ignition coils. Prolonged exposure to heat can degrade the insulation, reduce magnetic performance, and cause internal short circuits in coils.

Recommendations:

Use active cooling systems like forced air o r water cooling around the ignition unit.

Install temperature sensors o r thermal cutoffs to shut down the system if it exceeds a safe limit.

Keep the sputtering system in a climate-controlled environment, ideally below 25°C.

Regular maintenance of fans, filters, and heat sinks is essential to prevent coil overheating.
