An inspection system, for inspecting pin grid arrays on integrated circuit devices includes a pin base mask configured to receive a device having a pin grid array. A dark-field, low-angle lighting system emits light onto the pin grid array. The pin base mask and low-angle lighting system provide for a clear and definitive image of the pin grid array. A camera captures the image of the pin grid array. A processor, coupled to the camera, analyzes the images captured by the camera. Based on the captured image, the processor determines whether any pins on the pin grid array are bent or missing, or whether there are extra pins present.
