There are many types of wave solder machines; however, the basic components and principles of these machines are the same. The basic equipment used during the process is a conveyor that moves the PCB through the different zones, a pan of solder used in the soldering process, a pump that produces the actual wave, the sprayer for the flux and the preheating pad.  The solder is usually a mixture of metals.  A typical leaded solder is composed of 50% tin, 49.5% lead, and 0.5% antimony.<ref>{{Cite book|title=Manufacturing Processes Reference Guide

}}</ref> The [[Restriction of Hazardous Substances Directive]] (RoHS) has led to an ongoing transition away from 'traditional' leaded solder in modern manufacturing in favor of lead-free alternatives.  Both tin-silver-copper and tin-copper-nickel alloys are commonly used, with one common alloy (SN100C) being 99.25% tin, 0.7% copper, 0.05% nickel and <0.01% germanium.<ref>{{Cite web|url=http://www.aimsolder.com/sites/default/files/sn100c-sell-sheet.pdf|title=SN100C Solder|website=aimsolder.com}}</ref>
