Problems solved by technology

[0003] However, due to the different complexity of the PCB circuit, the file size of the data of different PCB graphics is also different. For complex graphics data, the transmission time will increase accordingly, resulting in lower production capacity.

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0028] The direct writing exposure machine needs to segment the pattern data to be exposed (referred to as exposure pattern data in the embodiment of the present invention) to the exposure control unit to realize the transfer of the exposure pattern to the substrate, wherein the segmentation is for Support scanning while sending data to realize real-time exposure.

[0029] Such as figure 1 As shown, since the exposure control unit performs rotation transformation and other processing on the data during the exposure display, in the traditional implementation method, some data of the previous segment of data needs to be sent repeatedly before each segment of data to ensure the lossless seam of graphics processing, At the end of each piece of data, some grid...

Abstract

The invention provides a method for processing exposure graphic data, an exposure control unit and a direct-writing exposure machine. The method comprises the steps: a relocation step of responding toreading completion of a segment of data, and enabling an address pointer of the read data to be located at an address of repeated data needed by the next segment of data; a reading step of reading the required repeated data and the next segment of data from a first storage unit according to the address of the repeated data needed by the next segment of data and the address of the next segment ofdata; and the step of repeating the relocation step and the reading step till that each segment of data of the exposure graph data is obtained. According to the method for processing the exposure graphic data, the first storage unit is added to store the exposure data, and the required data is directly read from the first storage unit without being sent again during data processing so that a transmission bandwidth of the data is saved, transmission time is also saved, and productivity of the exposure machine is improved.

Description

technical field [0001] The invention relates to the field of exposure technology, in particular to a method for exposing graphic data, an exposure control unit and a direct writing exposure machine. Background technique [0002] Direct writing exposure machine is the key equipment in the production process of PCB (Printed Circuit Board, printed circuit board) and mask plate. In the process of PCB and mask plate production, production capacity is a concern of every manufacturer. Direct writing The type exposure machine saves the exposure machine to make film and other links, and directly transfers the exposure pattern to the exposure substrate through DMD (Digital Micromirror Device, digital micromirror) to increase the production capacity of PCB. [0003] However, due to the different complexity of the PCB circuit, the file size of the data of different PCB graphics is also different. For complex graphics data, the transmission time will increase accordingly, resulting in lo...
