Abstract

In this study, we found that it is important to have a specific management of standards which are the $12{\pm}3{\mu}m$ of plating thickness and $2{\pm}1%$ of tuning. To verify these standards, we checked the plating thickness and density of tuning through marginal valuation of each and checked size of a plating particle, adhesion of solder and condition of reflow after a section chief.
