Surface Mount Aluminum Capacitor with
Foolproof Orientation Placement Design
Disclosed is a method for the construction of a new aluminum
capacitor, which includes a fool proof system that allows only one orientation
when mounting on printed circuit boards (PCB).
Existing surface mount aluminum capacitors can be incorrectly
placed on PCBs, even though there are recognition systems available on
placement machines. In high-volume industry manufacturing, not all equipment
has a vision system to capture the incorrect orientation of the component.
Currently, manufacturers depend on inspections (by
specialists or scanning machines) after the aluminum capacitor is mounted on a PCB
(see Figure 1). Rework is needed if a capacitor is placed incorrectly on a board,
and therefore incurs additional process costs.
The disclosed method includes a pin attached on the surface
mount aluminum capacitor. A hole and slot pin direction are drilled into the
surface of the PCB to ensure that there is only one way to orient the capacitor
(see Figure 1). In the disclosed method, an incorrectly oriented capacitor will
not seat properly, and it will fall from its location.
The disclosed method ensures a fool proof system for
orienting an aluminum capacitor in only one way on a PCB.
