Inert gas wavesoldering-process variables

The inherent stability of the Inert Gas Wavesoldering Process has given design and manufacturing engineers the opportunity to identify the sources of the more persistent defects on PBA. KBS can provide a means of assisting design and manufacturing engineers in their quest to reduce PBA defects. KBS can offer a range of facilities including dealing with uncertainty. KBS can be programmed to include an internal representation of all the expert knowledge relating to an engineering problem and can utilise this knowledge to solve the problem, give advice and draw inferences or conclusions based on the data provided. Like human experts, KBS are also able to explain the lines of reasoning used. KBS allied to techniques involving Statistical Process Control (SPC) and Design of Experiments (DOE) could contribute significantly to the pursuit in the electronics industry for zero defects
