Happy’s Essential Skills: Computer-Aided Manufacturing, Part 2 - Automation Examples
Computers Come to Plating[12]: Computers were first applied to PCB manufacturing at HP’s Palo Alto facility in 1974. Figure 12 shows the computer controlled plating system that included hoist (Figure 13) control, current control and monitoring for the plating tanks, chemical replenishment for the plating cells and multiple process sequence recipes (Cu, Sn/Ni, Sn & Au} that HP used for all its different 23,000 separate products.
