Measuring Soldering Tip Temperature Accuracy
This article is based on an original publication by James R. Hagan, Sr. Product Designer, Weller.
The Importance of Tip Temperature Accuracy
Tip temperature accuracy is a key performance factor for soldering stations, as inaccurate or ambiguous readings can lead to a range of issues. Overheating and temperature deficits can both negatively affect the soldering process.
- Overheating can promote trace lifting, poor solder joints, and damage to components or the circuit board. It can also result in oxidation or erosion of tip surface plating. Fluxes, which degrade at a higher rate with increased temperatures, may carbonize on the tip surface, forming black residues.
- Temperatures that are too low may cause poor heat transfer or longer dwell periods, leading to decreased productivity or poor solder connections.
