Temperature-measuring and temperature-controlling elements have small volume, light weight, high precision and fast anti-vibration response.
Thin film platinum resistance is a new type of temperature measurement and temperature control element. It has the characteristics of small size, light weight, high precision, anti-vibration, fast response and so on. MCF has successfully developed products with reliable performance in accordance with IEC751 standard, relying on functional materials and using advanced film forming and lithography technology. At present, MCF has been widely used in chemical industry, power generation, automotive, medical, pharmaceutical, instrumentation, aerospace, military and other fields.

Welding Effect of Lead and External Connection
|
welding method |
Explain |
|
Soldering |
Silver has excellent solderability and is more suitable for high temperature solders. Its technological properties are superior to platinum and gold plating. |
|
Crimping |
Silver has softer properties and is more firmly and reliably pressed with other metals. |
|
Welding (Electrode) |
Silver has good electrical conductivity, welding assistant characteristics, wide welding voltage regulation range, fast and reliable discharge at solder joints. |
|
Oxygen welding (flame) |
When the melting point of silver layer is low, it shrinks slightly, and the reliability of welding between nickel wire and wire does not affect the product performance. |
