Background

PVBA boards, also known as printed circuit boards and printed circuit boards, are important electronic components, support for electronic components, and are providers of circuit connections for electronic components. It is called a "printed" circuit board because it is made using electronic printing techniques. Before the advent of printed circuit boards, interconnections between electronic components were completed by direct wire connections. Circuit panels are now only available as effective experimental tools, and printed circuit boards have become an absolutely dominant position in the electronics industry. In the beginning of the 20 th century, in order to simplify the fabrication of electronic devices, reduce the number of wirings between electronic components, and reduce the fabrication cost, efforts have been made to replace the wiring method by printing. Over thirty years, engineers have proposed to use metal conductors as wiring on insulated substrates. In 1925, Charles Ducas in the united states printed a circuit pattern on an insulating substrate, and then successfully formed conductors for wiring by electroplating. Current PCBA board detects tucking mechanism adopts the fixed back level of PCBA board to push into the mode of test, and the mode of cylinder vertical upward movement is adopted to the test tucking board simultaneously, but the stroke of cylinder is difficult for carrying out accurate control, leads to the PCBA board to damage in the testing process because of the stroke is excessive easily.
