Electronics manufacturing laser PCB marking includes lettering and a matrix barcode


Lasers have enabled much of today's manufacturing processes for electronics. From precision cutting and drilling to detailed etching and marking, Synrad CO2 lasers are used in multiple processes, across a wide variety of materials in electronics manufacturing.

High processing speeds with a very high degree of accuracy are a must for lasers when used in electronics manufacturing. Stability and repeatability are key laser performance factors. Synrad lasers deliver consistent beam quality in the most demanding operational environments with little to no maintenance required.

Flexibility is another key advantage with Synrad. Laser processing applications for electronics manufacturing are very diverse, often requiring different lasers to perform a variety of processing tasks. Synrad offers a range of compact, lightweight CO2 lasers easily integrated onto stationary flatbed systems and gantry machine systems, and combines easily with multiple scanning systems. Further, Synrad offers a unique selection of air cooled CO2 lasers from 30 Watts - 100 Watts, engineered with the same beam output height and common 48 VDC input power for fast, easy upgrades and system design flexibility.

Wire Stripping

Precise wire stripping is fast and easy with a Synrad CO2 laser. The laser vaporizes the targeted insulation layer with absolute precision, leaving behind the conductive wire with no residue or damage. The laser can selectively remove one or more layers of insulation. Recommended wire stripping lasers:

Component Marking

Surface Mount Technology (SMT) chip resistors, capacitors, resistors, and thermoplastic electrical connectors are a few examples of the electronic components that use Synrad lasers for marking. Component markings vary from simple identification marks to variable codes. Synrad lasers excel at this application, offering multiple options for high-speed marking. Recommended component marking lasers:

Surface Treatment

Handheld electronics use a number of different materials for their outer casings that often require manipulation to improve grip or enhance tactile quality. Synrad lasers mark or ablate plastics, resin based composites, rubber and rubber-like materials to improve tactile quality for a wide variety of hand-held electronics. Recommended surface treatment lasers:

Vent Hole Drilling

Precision hole drilling for ventilation or enhancing sound quality requires a laser with high peak power and fast rise/fall times to create precise holes with minimal discoloration. Recommended vent hole drilling lasers:

Thin Film Cutting

Thin film cutting requires a laser with high peak pulse power to minimize melt lips and excellent power density for consistent results. Recommended thin film cutting pulse lasers include:

Glass Marking

Synrad pioneered laser glass marking and today often replaces sandblasting as the preferred method for marking glass. Laser marking glass avoids all the hazards associated with sandblasting while delivering faster, easier design or text change-overs with far better detail. Recommended glass marking lasers:

PCB Marking

PCB Marking requires a laser with good power stability to avoid damaging electrical traces when marking the solder masks with permanent, two-dimensional (2D) codes for traceability. PCB marking is done often with only 5 - 10 Watts of laser power, but with very fast cycle times to ensure fast throughput. Synrad offers a wide range of low-power lasers well suited for PCB marking.
