Engineered for high-reliability manufacturing in electronics, automotive, sheet metal, and pharmaceutical production lines in Thailand and Southeast Asia.
As Thailand cements its position as the premier advanced electronics, hard disk drive (HDD), and electric vehicle (EV) manufacturing hub in Southeast Asia—centered around the Eastern Economic Corridor (EEC) encompassing Chonburi, Rayong, and Chachoengsao—the demand for precision micro-machining has undergone a fundamental technological paradigm shift. Traditional thermal processing technologies such as CO2 lasers (10,600nm) and standard fiber lasers (1,064nm) often fail to meet the stringent quality standards required for sensitive substrates due to high localized thermal deformation, mechanical burrs, and severe Heat-Affected Zones (HAZ).
Ultraviolet (UV) laser systems operating at a fundamental wavelength of 355nm—achieved through Third Harmonic Generation (THG) of Diode-Pumped Solid-State (DPSS) lasers or advanced fiber-seeded architectures—revolutionize material processing via photochemical ablation (often termed "cold processing"). Unlike infrared photon energy that relies on photothermal melting and vaporization, high-energy 355nm UV photons directly break atomic and molecular bonds within organic polymers, ceramics, flexible printed circuit boards (FPCB), and semiconductor packaging materials. This eliminates micro-cracking, carbonization, and structural distortion, delivering edge tolerances within sub-micron parameters.

The industrial manufacturing ecosystem in Thailand is undergoing significant modernization driven by national economic policies and global technological shifts:
Building state-of-the-art laser machinery since 1991. Every platform is designed, assembled, and validated under rigorous ISO standards with dedicated R&D application laboratory testing.
We analyze your specific parts, run material trials, measure metallographic cross-sections, and prove process recipes before machine configuration.
Enclosures built with optical density-certified viewing windows, safety interlocks, dynamic fume extraction, and robust granite or welded steel bases.
Seamlessly integrate galvo scanners, 5-axis motion tables, automated robotic load/unload, and PLC/MES data connectivity into your existing line.
Flexible printed circuits (FPCBs) consist of delicate Polyimide (PI) and copper layers. A 1064nm fiber laser relies on thermal energy, which melts the plastic substrate, creates heavy carbonization (black charring), and causes copper layer delamination. In contrast, a 355nm UV laser utilizes photochemical "cold" ablation, directly snapping chemical bonds without thermal build-up. This leaves zero carbonization, pristine copper margins, and micro-edges requiring no secondary chemical washing.
Ultraviolet laser sources utilize non-linear Third Harmonic Generation (THG) crystals (such as LBO/BBO) that are sensitive to humidity and thermal fluctuations. Premium industrial UV machines from manufacturers like Scantech Laser feature hermetically sealed optical heads equipped with internal thermo-electric cooling (TEC) and continuous purge systems. When operated in air-conditioned cleanrooms or sealed Class 1 cabinets, crystal operational lifespan routinely exceeds 20,000+ hours.
Standard turnkey UV systems typically ship within 4 to 6 weeks following sample approval. Customs clearance via Laem Chabang port into EEC estates (Chonburi/Rayong) is streamlined under BOI privileges. Factory Acceptance Testing (FAT) is conducted at the manufacturing plant before dispatch, followed immediately by Site Acceptance Testing (SAT), optical calibration, and local operator training by specialized field engineers upon arrival.
Direct exposure to 355nm UV laser radiation poses severe risks to eye cornea and skin. Machines must feature fully enclosed Class 1 protective housing with OD6+ UV-rated viewing windows. Furthermore, because photochemical ablation of polymers generates ultrafine airborne particulates and toxic gases, integrated HEPA and activated carbon fume extraction units are mandatory for compliance with Thai Occupational Health and Safety regulations.
Yes. Scantech Laser specializes in custom special-purpose machines (SPM) and robotic integration. Systems can be configured with automated conveyor indexing, SMEMA interfaces, dual galvo heads, high-speed vision alignment cameras, and customized PLC software communicating directly with factory MES systems for complete Industry 4.0 traceability.
