Unformatted text preview: n control once an improvement was made. Specific Tier Two control methods depended on the type of equipment and the implementation and are explained in Section 5.1.5 and Appendix C. 5.1.5 Second Tier DMAIC case studies This section details two deep dives into Tier Two DMAIC projects that were conducted in CCA. While some data has been disguised for confidentiality, the analytical techniques and challenges are based on actual experience in the production environment. Additional information on other Tier Two DMAIC processes are included in Appendix C. Wave Solder Wave soldering is a large-scale soldering process by which electronic components are soldered to a Printed Circuit Board (PCB) to form an electronic assembly. The name is derived from the use of waves of molten solder to attach metal components to the PCB. The process uses a tank to hold a quantity of molten solder; the components are inserted into or placed on the PCB and the loaded PCB is passed across a pumped wave or waterfall of solder. The solder wets the exposed metallic areas of the board (those not, protected with solder mask, a protective coating that prevents the solder from bridging between connections), creating a reliable me...
