Picosecond UV laser cutting machine manufactures high-density circuit boards
(Click 440 )Under the trend of miniaturization and high frequency of electronic equipment, the line width of circuit boards has exceeded the limit of 50μm, and traditional mechanical processing faces bottlenecks such as edge collapse and burrs. Laser cutting technology has become an innovative tool for the manufacture of HDI boards and flexible circuit boards with its non-contact and high-precision characteristics, redefining the processing standards of electronic components.
The UV laser cutting machine uses a 355nm short-wavelength light source, and the focused spot diameter can reach 15μm, which can realize φ30μm micro-via processing on the FR-4 substrate, and the accuracy is 5 times higher than that of a mechanical drilling machine. Femtosecond laser technology controls the heat-affected zone within 3μm through 10^-15 second ultra-short pulses, perfectly cuts polyimide cover film without damaging the underlying copper foil, and the yield rate is increased to 99.8%.
The UV laser cutting machine equipped with a CCD visual positioning system can automatically identify the circuit board mark points and complete the engraving of an antenna array with a line width of 0.08mm on a 0.1mm thick ceramic substrate. For 10-layer high-density interconnect boards, the picosecond UV laser cutting machine can achieve a blind groove cutting depth error of ±5μm, meeting the impedance consistency requirements of 5G communication modules.
As semiconductor packaging technology evolves towards 3D structures, laser cutting machines are moving towards multi-wavelength composite processing. This technology not only supports the continuous evolution of smartphones and IoT devices, but also opens up a new dimension of precision manufacturing in aerospace electronics, medical implants and other fields.
