Thermal profiling: a reflow process based on the heating factor
Abstract
Purpose
This paper aims to offer a convenient method to develop an oven recipe for a specific soldering profile in a reflow process. The method is devised to quickly achieve proper profile shape and heating factor Qη, a measure of success for high reliability of the solder joints reflowed.
Design/methodology/approach
An in‐depth analysis of the heating mechanism and some experiments of the reflow soldering process are performed to research on how to realize a specific shape reflow profile were conducted.
Findings
Heating mechanism analysis and experiments demonstrate that the combinatorial parameters based method is feasible to do thermal profiling.
Research limitations/implications
The mapping function among a particular configured PCBA, an oven used, a target reflow profile and an optimal range of the heating factor should be further established for fast and reliable production of reflow soldering.
Practical implications
Provides a methodology for designing an oven recipe for reflow soldering production.
Originality/value
An oven recipe can be quickly attained with the approach established in this paper, facilitating the formation of solder joints with high reliability during the reflow soldering process.
