| titleOfInvention | A method for detecting the abnormality of the presser foot of PCB board production equipment |
| abstract | The invention discloses a method for detecting the abnormality of the presser foot of PCB board production equipment, comprising the following steps: S1, selecting a test PCB board with a copper-plated surface; Board storage; S3, carry out presser foot detection, place the test PCB board under the machine to be tested, the machine to be tested starts to operate normally, and perform clamping operation on the test PCB board; S4, take out the test PCB board after the operation is completed , and test the integrity of the PCB board film. The present invention performs special treatment on the test PCB board surface, and makes it into a special detection PCB board. By simulating operation, it can quickly detect and locate the presser foot or clamping parts of the whole process of testing the PCB machine, effectively avoiding the Machine detection is difficult and cumbersome, and it takes time and effort to disassemble the machine for confirmation. |
