Description

technical field

[0001] The invention relates to the technical field of circuit board manufacturing technology, in particular to an extended automatic marking device for a circuit board electric measuring machine. Background technique

[0002] Usually on the insulating material, according to the predetermined design, the conductive pattern made of printed circuit, printed component or a combination of the two is called printed circuit. The conductive pattern that provides electrical connection between components on an insulating substrate is called a printed circuit. In this way, the finished board of printed circuit or printed circuit is called printed circuit board, also known as printed board or printed circuit board. In the manufacturing process of the circuit board, the testing link of the electric testing machine is particularly important.

[0003] In the common circuit board production process, the electrical tester usually needs to manually mark and dot after the te...
