Drilling effect of China UV Laser Drilling Machine

In terms of industry quality requirements, we compared the domestic China UV Laser Drilling Machine can achieve the level of comparison.

Minimum through-hole diameter of the industry quality requirements: 50 microns. The performance of domestic equipment is 25 microns.

Industry quality requirements for minimum blind hole diameter: 75 microns, domestic equipment performance up to 75 microns;

The industry requires a blind hole with no residue and does not damage the bottom copper. The ground PI or glue of domestic equipment is clear and clean without the copper damage;

The industry consistency requirement of blind hole drilling effect is high. The effect of blind hole bottom of domestic equipment is also very consistent, and the range of processing parameters is wide.

Aperture roundness industry requirements are high: cutting edge smooth, sharp. Domestic equipment aperture 100 microns, roundness can achieve 95% above, diameter of 50 microns, roundness can reach more than 90%, 25 micron aperture, roundness can reach more than 85%, and orifice effect smooth sharp;

Regarding the stability of pore size, the industry requirement is plus or minus 5 microns. Domestic equipment can reach plus or minus 3;

The upper and lower hole diameter ratio of the blind hole is 80% >, and the hole wall should be smooth. When the aperture of domestic equipment is 100 microns, it can reach 85%, when the aperture is 50 microns, it can reach > 80%, and the hole wall is smooth.

Pass hole up and down hole diameter ratio, industry requirements to reach more than 85%, smooth hole wall. The domestic equipment can reach 92% when the aperture is 100 microns, 65% when the aperture is 25 microns, and the hole wall is smooth.
