Standard Copper Rigid/Bus

Design Characteristics

To achieve optimum results, select the type of rigid/bus and location on the board based on the following: current requirements, size of the board and degree of bend in the board. If the rigid/bus will be carrying current, select the body width according to the current carrying capacity. (see specifications below). Select the tallest possible conductor body compatible with your design, and increase the maximum pin count to maximize rigidizing. Clinch the pins on the bottom of the board alternating the clinch direction 180 degrees along the length of the part. CCI offers a clinching tool, or its manufacturing drawing, to simplify the clinching operation. The snap-in rigid/bus stiffener is ideal for cases where you want mainly to provide board rigidity and elminate the need for clinching pins.
