Guann-Ming Industrial (G.M Reels) is a plastic reel, IC-tray and injection manufacturer in Hsinchu, Taiwan, established in 1990. We supply EIA-481 SMD carrier-tape reels, vacuum-formed IC trays and custom injection parts to three parts of the semiconductor supply chain — packaging & test (OSAT), IC design (fabless), and semiconductor component makers. Located beside Hsinchu Science Park, we build for the ecosystem our products serve.
01One packaging partner, three segments
Reels, trays and custom plastics touch the semiconductor chain at several points. The needs differ by segment, so it helps to be explicit about what each one requires from a packaging supplier — and where Guann-Ming fits.
02Packaging & test houses (OSAT)
What they need: high-volume, dimensionally consistent EIA-481 reels for finished-package tape-and-reel; stable ESD control to protect packaged ICs; IC trays for device handling; an auditable quality system; and responsive, local supply that keeps high-throughput lines fed.
How Guann-Ming fits: EIA-481 carrier-tape reels in six sizes (4 / 7 / 10 / 11.25 / 13 / 15"), 8–56 mm band width; ESD grades with tested surface resistance (conductive 10⁴–10⁶, anti-static 10⁶–10¹¹ Ω/sq); vacuum-formed IC trays custom-tooled for device handling; ISO 9001 quality management; and Hsinchu-local delivery for short lead times and easy on-site audits.
03IC design houses (fabless)
What they need: reels and trays for sample and qualification runs; custom trays shaped to a specific device; small-batch tooling and fast turnaround while a design ramps.
How Guann-Ming fits: custom vacuum-forming and injection tooling matched to your device contour; small-batch samples; high flexibility and fast engineering response — the accommodation a design team needs before a package goes to volume at its OSAT.
04Semiconductor component makers
What they need: high-volume EIA-481 reels for passive and active components; stable ESD grades; worldwide shipping; and competitive landed cost, not just unit price.
How Guann-Ming fits: the full six-size reel range with anti-static / conductive / insulative grades; ISO 9001 and RoHS compliance; and a tool-free three-piece 13" reel that ships flat and cuts ocean-freight volume by roughly 60% — plus inquiries welcomed in any language.
05Capability matrix

| Component makers | High-volume reels, ESD, low landed cost | Full reel range, ESD grades, freight-saving 3-piece reel, worldwide shipping |
06Why a Hsinchu base matters
Guann-Ming sits beside Hsinchu Science Park, Taiwan's semiconductor heartland. For buyers, that proximity means short lead times, straightforward on-site audits, and same-timezone engineering support — a supplier that is close to, and fluent in, the industry it serves.
