Description

[Technical Field]

[0001] This invention relates to circuit board manufacturing equipment, and in particular to a highly automated integrated testing and stamping equipment for circuit boards that can effectively reduce production costs and improve production efficiency. [Background Technology]

[0002] Modern printed circuit board (PCB) production equipment is a large and complex system, with production efficiency and cost being core concerns for manufacturers. After the PCB undergoes processes such as inner and outer layer circuitry fabrication, lamination, drilling, hole metallization, solder masking, and silkscreen printing, it finally enters the forming and testing process. In traditional PCB manufacturing methods, quality testing and stamping are completed in two separate processes using two independent sets of equipment. The purpose of quality testing is to ensure that the electrical connections of the PCB are 100% correct, without defects such as open circuits or short circuits. The testing equipment can be flying probe testing devices, general grid testing devices, or bed-of-needle testing devices. Traditional stamping equipment is used to punch the designed shape, slots, and holes into the PCB. The equipment mainly includes milling machines, V-cutters, and laser cutters. In traditional PCB manufacturing methods, the aforementioned testing methods and equipment, as well as the stamping methods and equipment, are two independent systems, and the two processes must be performed on two different sets of equipment. For this reason, the testing and stamping processes in traditional circuit board production are carried out separately, resulting in complex procedures and many steps, which directly leads to reduced production efficiency and increased production costs, while also increasing the labor intensity of operators.
