Abstract

Automatic and innovative equipment was developed to inspect the assembly of pin-through-hole components on printed circuit boards. Its performance was tested on an industrial assembly line of motherboards for desktop computers. The test was conducted to inspect, under the binomial criterion Pass/Fail, the process of inserting PTH-DIMM components on semi-finished PCBs. Using the concept of Inspection Accuracy in binomial classification analysis it was estimated that the accuracy of this inspection is greater than 98%.
