  2. CO2 LASER APPLICATIONS ON CERAMICS • Marking PorcelainThis material provides a highly permanent contrasting mark, with some engraving. This component is used for electrical lamp plugs.Fenix, 25W, 5"/s..

  3. Marking Aluminum Nitride Aluminum Nitride marked using Synrad’s Fenix. • Using Synrad’s 25W Fenix Laser Marker and 80mm lens, this Polished Aluminum Nitride (Ceramic) sample was marked with 1mm high text characters at 2.5 inches per second in a cycle time of 0.2 seconds.

  4. Marking Clear Ceramic Marking high temperature clear ceramic using a 10W laser.   Heat resistant to 1400° F, the clear ceramic material in the photo is used for windows in high temperature ovens and furnaces.  The ceramic was marked with a 0.125" high human readable lot code and a 2D Data Matrix code using a 10W Synrad CO2 laser, with a cycle time of  3 seconds. 

  5. Marking polished ceramic surface mounts • This shuttle was marked on a surface mount • The mark was made with a 69mm lens and 13 watts of laser power. • A speed of 15'"/s was achieved, with high resolution. • This application calls for high marking speeds, as the surface mount material must be marked without overheating the part

  6. Marking Ceramic and Phenolic Capacitors • The flexible nature of laser marking is ideal for placing a printed mark onto very small, varyingly sized capacitors, with changing text. • Both ceramic and phenolic capacitors produce an excellent contrasting mark.

  7. Marking Ceramic Components • The electronics industry uses miniature surface-mount components extensively in the manufacture of circuit boards. • This large (2.5 mm x 3 mm) ceramic capacitor was marked using an FH-Series marking head equipped with an 80 mm lens.

  8. Drilling Ceramic • 75-micron holes drilled in 0.015" ceramic (alumina) using a Synrad  Evolution 240.

  9. Cutting Ceramic • This 0.014" diameter hole was trepanned through a sheet of 0.005"-thick ceramic.

  10. Cutting ceramic • 0.025” thick ceramic, cut with a Synrad 200 watt laser, at 15ipm

  11. Scribing Micro-Channels in PMMA • This 100-micron wide channel was made using only 6W of power on a sheet of super-cooled PMMA. • Enlarged view of the scribed channel

  12. Marking Surface Mount Capacitors • Marked with a Synrad 10-watt laser and FH-Series “Index” Marking Head at 15”/ sec (Actual size ~2mm x 1 .5mm)

  13. Marking Polyimide • Marked with the FH "Index" marking head and Synrad laser, using 5 watts at 30"/ second.The cutting of polyimide material for flex circuits and other electrical applications is a highly specialized area, with lasers of wavelengths in the 9.3-9.4 micron range commonly used in their processing.

  14. Marking PCB on its side • Marked with the FH "Index" marking head and 10 watt laser using 7 watts at 15"/second. • The available space on small PCBs for marking  part numbers or date codes is constantly decreasing - one of the reasons for the increased use of Data Matrix codes

  15. Marking LPI Solder Masks • LPI (Liquid photo-image able) solder masks are widely used on circuit boards as they offer high resolution, excellent electrical properties and compatibility with surface mount technology. • This LPI solder mask was marked using a Synrad CO2 laser and FH Series marking head without exposing the electrical traces, or otherwise damaging the board.

  16. Marking IC Chips • Marked with Synrad's FH "Index" marking head and a 10-watt laser at 45" per second

  17. Marking Graphite • Marked with a Synrad 50W laser at 2.5"/s • Graphite’s ability to absorb laser energy is well known among CO2 laser users, as this material can be used as a fairly effective beam stop. • While this high-threshold material does require at least 50 watts of power to mark, laser marking on graphite results in well-defined, dark contrasting marks

  18. Marking Electronic Chips • Incredibly small readable text created with Synrad 10W laser

  19. Marking Data Matrix Codes on PCB • This 0.08" sq. (~2mm. sq.), 26-character code was marked with a 10-watt Synrad laser and FH "Index" Marking Head at 19" per second.
