The G.M brand's flagship product — plastic reels for SMT electronics and semiconductor packaging, compliant with the EIA-481 design standard. Mainstream 7" / 13", covering 4 / 10 / 11.25 / 15 / 17 / 20" full sizes, 8–56mm tape width. PS / ABS material. Selectable ESD: anti-static / conductive / insulative. Since 1990, the G.M brand has been industry-recognized.
applicable to OSAT packaging, Fabless IC design, IDM component makers for SMD carrier tape packaging — 6 sizes × 3 ESD types × various hub specs, fully covering SMT mass production and ocean export shipping applications.
Once a plastic reel is loaded, everything — from tape feed and cover-tape peel to pick and place onto the PCB — depends on dimensional accuracy and smooth feeding. The animation below runs the whole flow, and shows why a reel's precision directly drives line speed.
The reel feeds the carrier tape into the placement machine, sprocket holes engaging the feeder tooth by tooth. Tape width and pitch follow EIA-481 so material feeds smoothly without jams.
Before picking, the cover tape is peeled back and taken up, exposing the components in the pockets. Peel force must be stable — too tight tears components, too loose drops them.
The nozzle aligns to a pocket and lifts the component. This step is most sensitive to reel precision — wobble or pitch drift and the nozzle misses.
Components land precisely on the PCB pads — over 20,000 an hour. A stable reel that feeds cleanly keeps the whole line fast and downtime-free.
Three-piece and two-piece assembly, flat-packed unassembled stacking and freight efficiency — demonstrated on real units, with an interactive 3D model for structural review.
Two identical flanges with a central hub twisted in between — the two flanges and central hub twist-lock into a complete reel.
Align the two halves and twist-lock them together — no tools required. Ships flat-stacked in the container and assembles at your plant — substantially reducing container volume and ocean-freight cost.

The most widely used reel among passive and active component makers — Guann-Ming's bulk-standard flagship. 178 mm flange, 60 mm shaft, a full set of 4 variants (A / B / C / D), covering 8 / 12 / 16 / 24 mm tape widths — for connectors, resistors/capacitors and mechanical parts in small-to-medium volume.
7" is the most widely adopted size among component makers — the sweet spot between per-reel capacity and shipping cost. Its 4 variants (A / B / C / D) cover everything from standard shipping to high-protection and flat-packed, container-saving builds.

The most widely adopted SMT reel size — GM-13E-X uses a two-piece + hub assembly that reduces export shipping volume by up to 60%. Specified by OSAT packaging houses, Fabless IC firms, and IDM component manufacturers for tape-and-reel packaging.
This three-piece 13" reel separates into two side pieces and one center hub, offering space savings and easy assembly for export shipping.
The large-format SMT mainstream spec — larger reels hold significantly more carrier tape, effectively reducing SMT pick-and-place machine changeover frequency for both passive and active components.
These large-size plastic reels hold more carrier tape and passive/active components, reducing changeover time on pick-and-place machines. We can also customize per different requirements using different materials.
A specialty format preferred by EU/US customers — one-piece molded, reinforced structure, built for durability. One of Guann-Ming's best-selling reel series.
The 10" series offers 4 models: GM-10A-X (one-piece, 109g, economical), GM-10B-X 12mm (two-piece, 150g, high-protection), GM-10B-X 8mm (one-piece molding, 130g, large label area), and GM-10B-X 16mm (two-piece, specialty for EU/US market). PS / ABS material options; oven-bake compatible.
7" and 13" are Guann-Ming's two flagship sizes. Beyond these, we also offer 4" for sampling, 10", 11.25" for European pick-and-place machines, and 15" as supplementary sizes, fully covering all scenarios from sampling to mass production.
The most economical option for SMD factories supplying customer samples. 8mm carrier tape width · 50mm shaft · 13mm center hole · PS / ABS material (blue / white) · all three ESD options available · MOQ 300 pcs.
Common mid-large size for SMT. 254 mm flange, one-piece molding, supports 8 / 12 mm tape. PS / ABS, all three ESD options, oven-bake compatible.
Standard spec for European pick-and-place machine formats. Features ample label area and oven-bake compatibility. A transitional size between 10" and 13", designed specifically for European specialty machine requirements.
Large size for wide tape. 380 mm flange, two-piece insert design, supports 8–44 mm wide tape. Flat-packed unassembled, it saves ocean container volume.
G.M Reels are available in three ESD specifications, matched to IC component sensitivity class and facility EPA (ESD Protected Area) requirements — select the correct grade to ensure compliant packaging throughout the supply chain.
With conductive carbon black additives, the reel body is made electrically conductive, rapidly dissipating accumulated electrostatic charge. Specified for highly ESD-sensitive IC components.
The mainstream choice for SMT mass production. Material or surface modification suppresses static generation and prevents triboelectric charging. Suitable for general electronic component packaging across all ESD sensitivity classes.
Natural PS / ABS material — inherently non-conductive. Applicable to insulation-required scenarios, or for packaging passive components where ESD protection is not specified.
Guann-Ming reels are produced via two core assembly methods: ultrasonically welded flanges ("one-piece molding") and "two-piece + central hub" configurations. The 13" size ships unassembled in a three-piece flat-packed format, saving significant ocean freight container space.
The two flanges are permanently joined by ultrasonic welding, presenting as a seamless one-piece structure from the customer's side. This yields high joint strength and long service life. Representative model: GM-10B-X (10") — reinforced structure, engineered for durability.
Two flanges with a central hub twisted in between — the flanges and hub twist-lock into a complete reel. Representative models: GM-13E-X (13") · GM-15A-X (15").
The three-piece export format — shipped unassembled as separate left flange / right flange / center shaft; customers assemble on receipt. Saves approximately 60% container space versus pre-assembled shipping. Representative model: GM-13E-X.
After 36 years exporting to the US and Europe, the enemy is "shipping air." Guann-Ming's two-piece reels separate and flat-pack, compressing the same quantity into far less volume. The animation below runs assembled → two-piece → flat-pack → dense container loading, and shows how the 60% is saved.
A standard reel ships assembled — bulky in the container, which pushes ocean freight cost up.
Guann-Ming's two-piece reel ships as two separate halves plus an axle, joined at your plant by ultrasonic welding strong enough to survive Pacific shipping vibration tests.
Unassembled and nested flat, the stacks pack very thin. For the same quantity, the volume is only about 40% of one-piece reels.
Flat-packed, a 40ft container holds far more, cutting container volume by about 60% — thinning out freight cost and sharpening export competitiveness.
6 reel sizes, each designed for different SMT machines, customer types, and production scenarios. From engineering sampling to large-scale mass production — from domestic production lines to ocean shipping export — each size has a corresponding optimal application.
Engineering Sampling · Low-Volume Trial Production. New product first article verification, lab stage, specialty machine testing.
Large-Scale Mass Production · EU/US Customers. LED strip modules and passive components in bulk. Shipping. One-piece molding reinforces the structure for a longer service life.
Specialty Machines · Custom Spec. Some older or non-standard SMT equipment requires the 11.25" format; shaft width can be customized per machine specification.
SMT Mainstream · Ocean Export. Three-piece unassembled format saves significant container space; customers assemble flanges and hub upon receipt.
Large SMT · High-Density Lines. High-capacity tape winding significantly reduces SMT machine changeover frequency. Ideal for IC and semiconductor bulk production and export shipping.

Full-reel estimate (≈ ±12%). Formula: (windable tape length − leader/trailer ≈ 600mm) ÷ pitch. Calibration: 0603 (8mm tape, 4mm pitch) ≈ 5,000 pcs on 7", ≈ 10,000–15,000 on 13". Actual varies with tape thickness, pocket depth and winding; standard pack quantities depend on the manufacturer.
