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 Synrads Fenix.
  • Using Synrads 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
  • Graphites 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. 

20
Marking Data Matrix Codes on Glass-filled Nylon
  • Marked with an FH "Index" marking head and
    25-watt laser, using 12 watts of power at 40"/
    second.
  • This 22 character code was marked onto an
    automotive part in 0.4s. The 0.4" square code is
    readable with a hand held scanner.
  •  

21

    seconds
  • All four codes were marked in 5 seconds

22
Marking Chewing Gum Wrappers
  • In this application, foil chewing gum wrappers
    were marked for tracking, quality, and inspection
    purposes using a Synrad 25W CO2 laser and
    FH-Series marking head equipped with a 125mm
    focusing lens

23
Marking Brake Pads
  • This brake pad can be marked on either side.
  • While an engraved mark can be produced on the
    actual contact side of the pad, a great
    contrasting mark can be made on the painted side
    (shown in the photograph above) at very high
    speed.
  • Both the text and code were marked in less than
    2 seconds.

24
Marking 2D Codes on FR4
  • A 2D Data Matrix code was marked on a sample FR4
    circuit board
  • A second sample, containing twelve 0.060 high
    alphanumeric characters, was marked using 12 W at
    25 IPS in a time of 0.22 seconds.

25
Marking 2D Bar Codes on PCBs
  • This 2-D bar code reads "Synrad CO2 Laser
    marking!"
  • Information-dense 2D codes can be quickly and
    easily marked directly onto the base material of
    PCBs using a low power sealed CO2 laser and
    galvo based marking head

26
Cutting Sandpaper
  • Cutting 0.04 aluminum oxide paper with 125 watts
    at 125/ minute.The thickness and abrasive
    nature of the aluminum oxide is a challenge for
    mechanical cutters, often resulting in tool wear
    and deformation of the paper.
  • The laser cuts the sandpaper with no visible
    signs of thermal damage, and, as in this example,
    offers the end-users the flexibility to create
    custom shapes.

27
Cutting PCB
  • Side view of PCB scribed using low power Synrad
    CO2 Lasers.

    charring, with no discoloration to its surface or
    underside.
  • 25 watts, 70" per minute
  •  

32
SYNRAD APPLICATION GLASS QUARTZ AND STONE
33
Stripping Optical Fiber
  • For many material removal processes, such as

    accuracy and power delivered with precise control
    to remove unwanted materials. 

34

    into the material, is fairly straightforward,
    generally requiring less than 25 watts of power

42
Marking Glass Diodes

  • 0.03"-high characters were marked on this diode
    using just 3 watts of laser power.

44
Laser Marking Glass to Resemble Sand Blasting
  • CO2 lasers mark glass by fracturing the surface
    of the material.
  • In this case , the glass was fractured to within
    2-3 thousandths of the surface, resulting in a
    very smooth finish.
  • This technique can be used to produce text, Data
    Matrix codes, and readable bar codes

45
Marking Decorative Glass
  • Marked with 15 watts of power at 100"/second.
  • In this application, the surface staining or
    coating on glass was easily ablated away,

  • The unique ability to cut out profile shapes with
    no mechanical force makes this application
    possible.

51
Cutting Optical Fiber
  • CO2 laser radiation is readily absorbed by glass,
    which makes these lasers ideal for cutting and
    machining of optical fibers, or as a heat source
    for fiber splicing
  • In this case, single-mode telecommunication
    fibers were cut with a 25-watt laser at a speed
    of 6" per second with 5 passes (0.3 second cycle
    time), using an 80mm focal length lens

52

    using only 9 watts of laser power, at a speed of
    2000ipm

53
Rust-Proof Marking Steel
