What common cooling system failures affect MS-HS sputtering equipment in Pakistan’s high-temperature conditions?

High ambient temperatures, especially during summer in areas like Sindh and Punjab, can overheat sputtering equipment if cooling systems underperform. This can lead to equipment damage o r deposition inconsistencies. What cooling system types chillers, water recirculators, etc. are best suited for the Pakistani climate? How often should cooling systems be maintained o r upgraded to ensure reliability in MS-HS applications?

In hot climates often exceeding 40°C, standard cooling systems underperform, leading to overheating of targets, power supplies, and vacuum components.

Best practices:

Use closed-loop water chillers with a minimum capacity of 2–5 kW, especially with copper o r stainless steel piping.

Regularly clean filters and check coolant levels monthly.

Install temperature sensors on key components like magnetrons, RF generators, and target holders.

Avoid using tap water as a coolant due to mineral buildup instead, use deionized o r distilled water.

Maintain lab temperature below 25°C using air conditioning o r ventilation.
