ECD produce a range of advanced thermal profiling systems and software for detecting and analysing process temperatures across a number of applications, particularly in the electronics and solar industries. ECD are renowned for the rich data produced by their software and the robustness of their hardware. ECD’s strong reputation has allowed the brand to establish themselves as the thermal profiling choice for engineering professionals across the globe.
ECD Thermocouples are established when two dissimilar metals are joined together using a welded bead. In order for a thermocouple to provide a temperature reading, the welded bead must come into direct contact with the object the user is looking obtain a temperature measurement from. To achieve an accurate thermal profile, it’s vital that the user attaches the thermocouple to the component or solder joint correctly. Obtaining an accurate reading from the outset provides the data needed for ensuring a good result.
Indeed, there are several methods for attaching thermocouples, each appropriate for particular scenarios. The most accurate thermal connections are attained when using materials with similar thermal conductivity to the material being thermally profiled by a user. For instance, if a solder joint is being profiled then a solder connection would be most appropriate, while plastic components should be profiled using a plastic connection.
ECD Thermocouple Attachment Methods
This blog will outline the most effective methods of attaching thermal attachments to assembly boards and how you can choose the best components to provide the most accurate measurements for thermal profiling.
Solder provides the most precise attachment method for measuring the thermal profile of solder joints, and has the added advantage of easy application and removal with minimal damage to PCBs.
Epoxy offers an effective method for obtaining a thermal profile of plastic components and PCB substrates. Epoxy is durable and therefore suitable for long-term use, though it can often be time-consuming to cure and problematic to remove without causing damage to components or the thermocouple.
Kapton and aluminium tapes
Kapton and Aluminum tapes can be applied and removed easily to reduce the likelihood of damage to components. Aluminum tapes featuring a silicone adhesive are likely to provide the most accurate readings as it will conduct heat through to the thermocouple. While kapton tape may be a good insulator, it should only be used to strain relief the thermocouple wire as it approaches the sense point.
ECD Temprobe is a patented temperature sensing device, which can be attached and removed easily with no soldering required. The ECD Temprobe therefore safeguards against any potential damage to components and provides a long-term thermocouple solution.
