Effect of welding parameter on pitch angle for electronic circuit process

Abstract

Laser welding process plays important role in assembling the small component. In the process, thereare many parameters that must be controlled in order to yield the good welding quality such as currentpower, welding time, inert gas feed rate, pressing force, and welding position. An understanding in thecharacteristics of those parameters makes the engineers to improve the quality of welding. This researchstudies the effects of those influent parameters to the pitch angle of the welding joints. The Box-Behnkenmethod is investigated for design the experiment. The parameters for controlling the machine arevaried within the available range of the welding. The experimental data is taken into account for analyzing statistically and the variation of the data is of interest. The experimental data is then taken into accountfor formulating the correlations between the pitch angle and those welding parameters. The correlationscan be used to predict the effect of each parameter to the pitch angle and leading to apply in thewelding process.
