Abstract

The invention relates to a double-faced exposure architecture and a double-faced exposure method of a printed circuit board. The double-faced exposure architecture at least comprises an exposure frame, an aligning lens, an upper photographic plate, a lower photographic plate, a rigid clapboard and an aligning device, and the upper photographic plate and the lower photographic plate are separated by the rigid clapboard, thus avoiding scratching, and the lower photographic plate is aligned with a previously arranged exposure location of the upper photographic plate through the aligning lens, thus achieving the goal of double-faced exposure aligning of the printed circuit board.

Description

technical field [0001] The invention relates to a double-side exposure structure and a double-side exposure method, in particular to a double-side exposure structure and a double-side exposure method for double-side exposure alignment of a printed circuit board. Background technique [0002] The double-sided exposure technology of the printed circuit board is to place the printed circuit board in the exposure frame of the double-sided exposure machine, and through the positioning of the upper film and the lower film, and then sandwich the printed circuit board to be exposed between the upper film and the lower film. Between the lower negatives, according to the alignment image captured by the CCD camera, the printed circuit board needs to be aligned with the upper and lower negatives relative to the exposure position, and then double-sided exposure is performed. However, before the upper film and the lower film are positioned on the upper frame and the lower frame of the exp...
