Micro Square

What Micro Square does

Micro Square (マイクロ・スクェア株式会社, Microsquare, Inc.) is a privately held Japanese manufacturer of precision optical inspection equipment and UV-LED irradiation systems, headquartered in Japan. The company operates two principal product lines: (1) digital microscopes (DS series) and BGA inspection scopes (MS-1000A series), the latter differentiated by a proprietary side-view prism design enabling direct observation of BGA package solder joints for bridge, crack, and unsoldered defect detection—a capability not available from standard upright microscopes; and (2) UV-LED irradiators (spot, area, line, deep-UV sterilization, and surface disinfection types) designed and manufactured to customer specifications from single-unit quantities, using wavelengths spanning 365nm–405nm for curing and 275nm/280nm for sterilization.

The commercial model is B2B hardware sales—direct, sales-led, and primarily domestic (Japan)—with quote-based pricing for custom UV-LED systems and listed SKUs for standard microscopes (e.g., ¥198,000 for DS-3A; ¥580,000 for DS-400C with Leopard software). Bundled software (Achcam Measure, Leopard, MicroLabo) provides measurement, depth synthesis, image stitching, and report export, with multilingual interfaces (Japanese, English, Chinese). Revenue is generated through one-time hardware sales plus aftermarket accessories (replacement prisms, calibration rulers, camera upgrades for Windows 10/11 compatibility at ¥90,000). The company serves electronics manufacturing, automotive, aerospace, medical device, and R&D customers, with a core supply partnership with Nichia Corporation for 280nm deep UV LED elements used in its sterilization products. No funding rounds, no subsidiaries, no public financials, and no certifications are disclosed.

Core offering

Micro Square designs, manufactures, and sells precision optical inspection and UV-LED irradiation equipment. The portfolio includes digital microscopes (DS series) for PC- or monitor-connected magnified observation and measurement, BGA inspection microscopes (MS-1000A series) using a proprietary side-view prism to inspect hidden solder joints, and customizable UV-LED irradiators (spot, area, line, and deep-UV sterilization types) for curing, bonding, and surface disinfection applications. Products are built to order from single-unit quantities and supported by bundled measurement software and accessories.

Product overview

Micro Square (マイクロ・スクェア株式会社) designs and manufactures precision optical inspection and UV curing equipment. The product portfolio consists of three core hardware lines — (1) Digital microscopes (DS series, including DS-3A compact PC-connected type, DS-3I compact full-HD type, DS-50A zoom type, DS-50HD full-HD type), (2) BGA inspection microscopes (MS-1000A series: MS-1000A, MS-1000A-EX, MS-1000A-LS) using a proprietary side-view prism design for BGA/IC package solder inspection, and (3) UV-LED irradiation systems (spot, area, line, deep-UV sterilization, and surface disinfection types) — all available from single units with custom design. All microscope products share measurement software (Achcam Measure as standard, Leopard and MicroLabo as optional upgrades) providing calibration, dimensional measurement, depth synthesis, image stitching, and report export. The company also offers scope accessories (stands, stages, lighting) and a backlight system (BL-SYSTEM-01) for advanced BGA ball array inspection.
