Laser drilling and cutting for PCB shops

Stress-free processing of rigid PCBs, FPCBs and coverlays

With easy handling, a small footprint and short changeover times LPKF laser systems offer best-in-class solutions to help customers compete in today's on-demand world. The laser allows for maximum use of the base material and production time.

Your benefits with LPKF's new CleanCut and short pulse technology

LPKF's CleanCut technology works in the optimum pulse duration range for PCB material processing. Within the short pulse regime the pulse duration plays a major role in processing efficiency. Industrial applications in which the total processing time is important benefit significantly from using specialized laser technology.

Increased Yield

Micro via drilling: Increased yield in the plating steps as a result of high-quality vias with perfect via shape.

Increased Reliability

Cutting: Unique and proven CleanCut technology drives carbonization down to zero for increased reliability and life-time of PCBs.

Increased Productivity

Coverlay cutting: Dust- and burr-free cutting increases productivity. No cleaning required.

Increased Profit

New opportunities: Impressive line/space ratio of below 20 µm enables next-generation products to be created-- flexibly, precisely, and rapidly.

New LPKF PicoLine laser systems

Clean cuts and precise vias – Surpassing industrial standards.

Based on the MicroLine platform, LPKF has developed a solution for meeting even higher demands on laser manufacturing quality: LPKF PicoLine. With this new laser system, LPKF meets the highest expectations regarding quality and cutting speed.

The system increases yield and production efficiency in PCB processing – resulting in fast return on investment. Equipped with a pico-second laser, the ultra-short pulse laser system LPKF PicoLine 5000 stands for highly precise positioning and accurate processing of PCB materials such as FR4 and PI-, LCP-, and PTFE-FPC in all industry-standard panel sizes.

Due to the CleanCut shortpulse technology, the heat-affected zone (HAZ) of the material becomes negligible.

PCB Routing

The LPKF lasers are suitable for cutting all industry-standard panel sizes with dimensions of up to 533 x 610 mm (2'' x 2''). The 20-μm high-quality UV laser kerf width allows for cutting of even the most delicate contours at high speeds.

FR4 routing with abolut clean cutting walls.

PCB cutting with CleanCut Technology

PCB routing -- SEM cross section. No dust, no debris.

PCB Skiving

Laser skiving is a selective ablation process that can remove one material with or without affecting an underlying material. Laser skiving can be performed to clear all dielectric material or to stop without cutting all the way through. Please also see "ablation of inorganic material from organic material."

Cavities

Depending on the material and its depth, cavities produced by laser may exhibit tapered walls. LPKF cutting techniques allow for steep side walls with perfect geometries.

Coverlay Cutting

Effective cutting speed up to 500 mm/s, dependent on materials and layout
Clean cutting edges: no heat-affected zone (HAZ), no carbonization
Smooth cuts: no burr or bulging; burr height reduced to less than 10 μm.
Uncontaminated surfaces: no particles, dust or dirt

Coverlay
