Embodiment 1
[0036] The micro-pitch stencil electropolishing process includes the following steps:
[0037] Step 1: Encapsulate marker points:
[0038] 1.1. Place the steel sheet to be polished on the inspection table for preliminary inspection to confirm whether there are creases on the surface of the steel sheet and whether the pad is deformed, and give feedback in time.
[0039] 1.2. Use alcohol to wipe the area of the marking points pre-set on the steel sheet to ensure that the surface of the marking points is clean, then use the round adhesive tape to seal the marking points tightly, and ensure that the marking points are placed in the center of the round adhesive tape.
[0040] 1.3. Put the steel sheet in the grinding machine and grind it on both sides to improve the processing accuracy of the steel sheet. After grinding, use a brush to clean the opening area on the printing surface in the vertical and horizontal directions, so as to facilitate the hole diameter comparison and clea...
