In Figure 2 you see part of one of the six manufacturing lines available at Corsair. The very first machine on the left side applies solder paste to the memory module printed circuit board (PCB). The second machine is placing small components like capacitors and resistors on the memory module, while the third machine is placing the memory chips on the module. After passing through these machines the memory modules go to an oven where the solder paste will melt thus soldering the components.
This four-machine set shown on Figures 2 and 3 is what is called “manufacturing line” or simply “line”.
After coming out of the oven, the memory modules are taken out of the panel and have their SPD chip programmed. Then the memory module is tested.
