Embodiment 1

[0055] This embodiment provides a laser direct writing data processing system according to the technical solution of the present invention, as shown in the attached Figure 4 As shown, the system includes a host, a data processing module and a DMD.

[0056] Among them, the data processing module is composed of data receiving unit, FPGA V6, DDR and DLP chipset (see attached Figure 5 )——FPGA V6 is the data processing unit, the model is XC6VLX240T, and DDR is the storage unit. The DLP chipset includes two DLP chips, a FLASH chip and an FPGA V5 chip (see attached Figure 6 )——The FLASH chip is a program storage chip, and the FPGA V5 chip is an image transmission chip.

[0057] The host generally can be a PC, various servers or various industrial computers. By carrying a software system, the host computer can perform corresponding data processing.

[0058] DMD is a commonly used SLM. Under the action of the light source, the DMD projects the received frame image onto the subs...

Embodiment 2

[0078] This embodiment provides another laser direct writing data processing system according to the technical solution of the present invention. Compared with Embodiment 1, the system of this embodiment has some changes in the structure of the data processing module, as shown in the attached Figure 9 As shown, the data processing module in this embodiment is composed of a data receiving unit, an ARM+FPGA, a DDR and a DLP chipset.

[0079] Wherein, the ARM+FPGA corresponds to the FPGA V6 in Embodiment 1, and is a data processing unit, and the ARM+FPGA can also be replaced by an SoC chip, and the mainstream SoC chip manufacturers are Altera or Xilinx.

[0080] In Embodiment 1, the host completes the rasterization of graphics, which requires high computing power of the host; the solution in Embodiment 1 does not support the working conditions of multiple DMDs. However, if the rasterization work is performed by the FPGA, the development of the FPGA is more difficult. In this em...

Description

technical field [0001] The invention relates to the technical field of laser direct writing, in particular to a laser direct writing data processing system and processing method. Background technique [0002] Laser direct imaging (laser direct imaging, LDI for short), also known as laser direct writing, is a technology developed in recent years for the exposure process of printed circuit boards (PCB). The traditional exposure process is to transfer the image to the PCB by irradiating the film with a mercury lamp, while LDI is a maskless exposure system that converts the vector graphics into a bitmap with the resolution required for production and projects it onto the PCB through the DMD. Compared with the traditional exposure technology, the LDI exposure process does not require film, which effectively reduces the cost, and has a simple process and high image precision, which can adapt to finer graphic exposure and is also conducive to improving the yield rate of PCB product...
