Problems solved by technology
[0003] When the circuit board is processed, it is necessary to expose the solder resist ink on the circuit board, and the ink needs to be exposed. The existing exposure process cannot solve the dust problem, and it is easy to make the circuit board stick to dust. Therefore, the present invention proposes a lifting alignment Accurate and efficient ink exposure process to solve the deficiencies of the existing technology
