Pump Laser Marking Machine — End-Pump & Side-Pump YAG/Fiber for PCB Engraving and Logo Etching
A conveyorized laser marking workstation for permanent PCB engraving — serial numbers, barcodes, QR codes, date codes, and logos. Available in end-pump YAG (20W/30W) for fine detail on anodized aluminum and coated steel, and side-pump YAG (50W/100W) for deep engraving on stainless steel and titanium. The galvanometer scanner delivers 7000 mm/s marking speed at 0.01 mm position repeatability, with a 110 mm × 110 mm marking field and 0.05 mm minimum character height.
What Is a Pump Laser Marking Machine?
A pump laser marking machine is a solid-state laser system that uses an optical pump source (flash lamp or diode) to excite a YAG (yttrium aluminum garnet) crystal doped with neodymium (Nd) or ytterbium (Yb). The laser emits at 1064 nm in the near-infrared, which is absorbed by most metals, plastics, and coated surfaces. The beam is steered by a galvanometer scanner to write text, graphics, and machine-readable codes on the workpiece without inks, solvents, or consumables.
There are two main pump configurations: end-pump (lamp or diode injected along the optical axis, lower power 20–30W, smaller spot ~0.05 mm, ideal for fine detail and small characters) and side-pump (pump sources injected radially through the barrel, higher power 50–100W, larger spot ~0.15 mm, ideal for deep engraving and high-speed marking). For most PCB marking applications (serial numbers, barcodes, logos on FR4 substrates or aluminum nameplates), the end-pump configuration is preferred for its finer detail. For industrial stainless-steel nameplate engraving, the side-pump configuration is preferred for its deeper mark and faster speed. For comparison with our fiber-laser line see the fiber laser marking machine product page and for CO2 options the CO2 laser marking machine.
Marking Process & Materials
The pump laser marking process has four stages: design file import, galvanometer scan, material ablation, and (optional) post-clean. The laser pulses at 20–200 kHz with 4–200 ns pulse width to vaporize a controlled depth of material without thermal damage to the substrate.
