Company profile
YJ STAINLESS CO., LTD. was founded in 1985 and describes itself as a professional wafer-frame manufacturer with 40 years of experience in Taiwan. The company began with professional manufacturing of stainless-steel products and expanded its product line into the high-tech semiconductor industry through continuing technology improvement, equipment upgrades, and product expansion. It states that its semiconductor products and manufacturing capability have received recognition from semiconductor companies around the world. Its semiconductor-related product range extends beyond wafer frames to cassettes, shipping boxes, wafer boxes, and other handling and storage products. Customization services cover dimensions, thickness, surface treatment, laser engraving, grooving, and cleaning services so that wafer-frame specifications can be adjusted to customer requirements. For production planning, the company states that it controls material preparation and inventory, integrates the supply chain, and uses lean management to manage production schedules and scheduled delivery. This production-control approach is also intended to support urgent-order delivery requirements when customers need accelerated supply. Its quality-management system is certified to BSI ISO-9001, and the company also lists SGS RoHS hazardous-substance testing as part of its product-quality assurance framework. In addition to manufacturing, YJ STAINLESS CO., LTD. provides professional wafer-frame refurbishment and cleaning, linking new-product supply with maintenance and reuse services for semiconductor handling components.
Exhibits
YJ STAINLESS CO., LTD. offers wafer-frame cleaning services that include ultrasonic cleaning, high-precision polishing and grinding, eco-friendly refurbishment, selectable surface-roughness restoration, CNC processing, and laser engraving. Its refurbishment process uses high-precision polishing and grinding equipment to restore iron wafer rings toward their original surface roughness and brightness, with the stated purpose of extending product life and restoring performance. The professional cleaning process uses ultrasonic systems together with customized debonding cleaning and deep-pressure degreasing to remove contamination from wafer frames. The cleaning process can remove 2D barcodes, logo stickers, and blue protective films while restoring the frame surface. The core handling-product categories include Wafer Frame/Metal Frame, wafer shipping boxes and Wafer Cassettes, Wafer Frame Shipping Boxes and Wafer Frame Carriers, Wafer Stack Boxes, Plastic Wafer Frames, Grip Rings and Expander Rings, Wafer Frame Boxes, and Wafer Tweezers. Named coin-box products include 12 Inch Wafer Coin Box TJF-G12-H30 and TJF-G12-H50.5, 6 Inch Wafer Coin Box TJF-G6-H76 and TJF-G6-H38, and 8 Inch Wafer Coin Box TJF-G8-H76. Dry-cabinet products with a listed 15-50%RH range include YJ-15B-600, YJ-15B-575, YJ-15B-400, YJ-15B-315, YJ-15B-200, YJ-15B-157, and the YJ-15B-1200 semiconductor storage cabinet. Wafer-cassette and wafer-box products include 6 Inch and 8 Inch Wafer Cassette Carriers, 3 Inch Silicon Wafer Box TJF-3-box, 4 Inch Silicon Wafer Box TJF-4-box, and 12 Inch Wafer FOUP / Wafer SMIF Pod / Tape Frame FOUP TJF-U12-25S. Metal-frame products include a 6 Inch Wafer Frame, an 8 Inch Dicing Ring, a 12 Inch Wafer Frame / Disco Wafer Frame, Square Wafer Frame TJF-C, Grooved Wafer Frame TJF-C-2, and Customized Disco Wafer Frame TJF-C-3. Plastic wafer-frame models include TJF-6P-2.5, TJF-8P-2.5, and TJF-12P-2.5 for 6 Inch, 8 Inch, and 12 Inch formats. Wafer-frame cassette models include TJF-C6, TJF-C8, and TJF-C12, while single-film-frame metal shippers include TJF-S6, TJF-S8, and TJF-S12. Expander-ring shipping boxes include TJF-SI45 for 4 and 5 Inch wafers, TJF-SI678 for 6, 7, and 8 Inch wafers, and TJF-SI12 for 12 Inch wafers. Teflon/PFA wafer cassettes include TJF-A6, TJF-A8, the low-profile TJF-A8-1, and TJF-A12. Wafer-frame boxes are listed as TJF-B6, TJF-B8, and TJF-B12, and high-tech-polymer wafer tweezers are listed as TJF-M1, TJF-M4, and TJF-M8. Grip and expander ring models include TJF-R6, TJF-R8, and TJF-R12 for 6 Inch, 8 Inch, and 12 Inch formats. Wafer shipping boxes include TJF-W4, TJF-W6, and TJF-W8, while wafer stack or storage boxes include TJF-P6, semiconductor-grade TJF-P8, and TJF-P12. Single-tray products include 2 Inch Wafer Single Tray TJF-O2, Wafer Single Tray TJF-O4, and single-tray Wafer Shipping Box models TJF-O6, TJF-O8, and TJF-O12. The broader product list also includes customized wafer-frame processing services, machine casings, cleanroom equipment, cleaning and maintenance services, dry cabinets, stainless-steel sinks, countertops and worktables, and a range of customized stainless-steel products. Other listed stainless-steel custom products include retractable barriers, decorative items, bicycle racks, lockers, chairs, shelves, trolleys, medical equipment, barrels, umbrella stands, work tables, and display racks, alongside black-iron and galvanized custom products.
