[0015] Now combined with figure 1 To further describe the specific technical solutions of the present invention, so that those skilled in the art can further understand the present invention, without restricting their rights.
[0016] (1) Prepare the boss quartz glass substrate by machining, as shown in 4 in the attached drawing;
[0017] (2) Choose a quartz glass capillary with an inner diameter of 0.5mm and an outer diameter of 2mm, and formulate a specific microchannel direction, as shown in the "Zigzag" direction shown in 3 in the attached drawing. The quartz glass capillary is welded to the convex by hot-melt technology. Table surface
[0018] (3) Use a notching machine to cut the grooves to prepare the grooved quartz glass plate substrate, as shown in Figure 9, the groove depth is greater than the sum of the height of the boss and the outer diameter of the quartz capillary, and the difference between the two is 2mm; Use a drilling machine to make 4 through holes, such as 5, 6...
