Yumex YML-3000 3000W Mercury Capillary High Pressure Lamp for PCB Exposure and Water-Cooled UV Systems

are 3000 watt mercury capillary high pressure lamps made by Yumex for demanding ultraviolet exposure applications, including printed circuit board exposure equipment and compatible water-cooled lamp systems. Designed for high-intensity pulsed lighting applications, this lamp is specified at 1960 volts, 1.8 amps, and a 3.54 in (90 mm) arc gap, with a listed average service life of 8000 hours. It is a practical replacement lamp choice for production environments where exposure consistency, compatible electrical operation, and correct arc geometry are essential to maintaining process quality. Before ordering, verify the lamp model, arc gap, lamp-house fit, power supply compatibility, cooling arrangement, and any OEM cross-reference requirements. High pressure mercury capillary lamps must be installed only in properly shielded, interlocked, and cooled equipment by qualified personnel.

Applications

Printed Circuit Board Manufacturing

• Exposure of printed circuit boards in compatible UV exposure and photolithography systems
• Photoresist imaging where a high-intensity mercury lamp source is required
• Replacement lamp programs for legacy PCB exposure equipment

Electronics Production and Process Engineering

• Water-cooled UV lamp systems used in production, pilot-line, and process-development environments
• Applications requiring a defined 3000W mercury capillary lamp format rather than a general-purpose UV bulb
• Maintenance replacement for equipment where lamp electrical rating and arc geometry must match the original configuration

Laboratory and Photochemical Exposure Work

• Specialized UV exposure setups that require high-intensity mercury spectral output
• Photochemical and materials exposure applications where the process has been validated around mercury capillary lamp technology
• Engineering evaluation of mercury capillary lamp replacement options for existing lamp houses

Features

• Designed for high-intensity exposure work: Suitable for demanding UV exposure applications where process repeatability depends on the correct lamp type and operating geometry.
• Mercury capillary high pressure lamp technology: Provides the concentrated radiant output expected from mercury capillary lamp systems used in PCB exposure and similar industrial applications.
• Intended for water-cooled equipment: Appropriate for compatible systems that use active cooling to manage lamp heat during operation.
• Useful for legacy system support: Helps maintain production equipment that was designed around mercury capillary lamp exposure rather than LED or laser-based exposure sources.
• Clear replacement identification: The YML-3000 model number, Yumex brand, and electrical rating make it easier to verify fit before ordering.
• Process-focused buying guidance: Recommended verification points include lamp model, arc gap, current, voltage, cooling configuration, lamp-holder fit, and OEM equipment compatibility.

FAQs

What is the YML-3000 mercury capillary lamp used for?

The YML-3000 is used in high-intensity pulsed lighting applications, mainly printed circuit board exposure, and is also listed for use in water-cooled systems. Confirm compatibility with the specific exposure tool before ordering.

Is the YML-3000 a direct replacement for my existing PCB exposure lamp?

It may be suitable when the equipment requires a Yumex YML-3000 or a lamp with matching electrical, arc-gap, cooling, and mounting requirements. Verify the original lamp model, power supply rating, operating current, voltage, lamp-house dimensions, and water-cooling arrangement before purchase.

What are the main specifications for the YML-3000?

The listed specifications are 3000 W power, 1960 V voltage, 1.8 A current, 3.54 in (90 mm) arc gap, and 8000 hours average lifetime. 

Can a mercury capillary lamp be replaced with a UV LED system?

In some processes, UV LED exposure may be evaluated as an alternative, but it is not automatically interchangeable. Mercury capillary lamps and UV LEDs differ in spectral output, exposure geometry, intensity distribution, thermal behavior, optics, and process validation requirements. For validated PCB exposure systems, use the lamp type specified by the equipment manufacturer unless the process has been requalified.

Does the YML-3000 require special handling?

Yes. This is a high pressure mercury lamp used with high voltage and intense ultraviolet output. It should be handled only by qualified personnel using proper protective equipment and installed only in compatible, shielded, interlocked, and cooled equipment. Follow all facility safety procedures and applicable mercury lamp disposal rules.

What should be checked before ordering?

Confirm the exact lamp model, manufacturer, wattage, voltage, current, arc gap, lamp end configuration, cooling method, equipment model, and any OEM cross-reference requirement. When in doubt, provide the existing lamp label and equipment model before ordering.

Warranty

High pressure mercury capillary lamps are specialized consumable components whose service life depends on compatible electrical operation, proper cooling, clean installation, correct handling, and validated system conditions. Warranty support, when applicable, may require order information, lamp model, equipment model, operating history, photos of the lamp and lamp label, and a description of the failure mode. Contact LabgearUSA.com customer service before returning any lamp.

Ordering

Order the YML-3000 when your equipment specification calls for a 3000W Yumex mercury capillary high pressure lamp with matching electrical and arc-gap requirements. For best results, verify compatibility before purchase, especially for PCB exposure tools and water-cooled lamp systems.
