21CENTURY CO., LTD.

The 21Century Co., Ltd. produces a variety of ultra-precise vacuum plates used in MLCC and semiconductor industries.
Because industrial vacuum plates have large suction holes, they can damage objects, and the demand for precision vacuum plates composed of micro holes is increasing. In the case of thin sheet-type products such as Film, a vacuum plate made of micro holes is needed because if the hole is large, the product may be damaged or embossed.

As a result, in the 21Century, high-precision vacuum plates consisting of micro holes processing up to Φ0.005 mm (The minimum hole size may vary depending on the material and shape) are produced and supplied to various industrial area. Although the vacuum plate made of Porus Ceramic is widely used in the semiconductor field, it is unstable in high floor plan and uniform pressure management due to the size of the particles, and the importance of the vacuum plate of 21Century is emerging.

Although it varies depending on the size of the specification, we manufacture and provide the highest quality and performance vacuum plates for customers’ needs with 0.005 floor plan management and precise suction hole management up to Φ0.03.

The 21Century Vacuum Plate, which boasts high quality and performance, was selected as the next world-class product in 2023 and won the official brand certification of the Korean government as a leading product and company in the global market.

21C has precision shape processing technology for MCT and high-speed processing machines and ultra-precision grinding technology using fine holes and shaping technology ELID using laser. Based on this, all products made of special ceramic materials such as general Alumina ceramics to ZrO2, SiC, AlN, SiO2, and MMC are manufactured and produced.

Various ceramics with excellent chemical and wear resistance are precisely processed and supplied to the electric and electronic fields as parts.

Alumina (AI₂, O₃)

Zirconia (ZrO₂)

Silicon Nitrode (Si₃N₄)

Silicon Carbide (SiC)

Recently, as the demand for ceramics increases, the demand for ceramics, graphite, silicon, and sodium oxide having various characteristics is also increasing. These materials are not included in our major business areas, but like other non-ceramic materials, they can be supplied according to customer requests.

1. Precision Ceramic Parts Production for Semiconductor and LCD Parts
2. Production of indexable and various precision Jigs for MLCC
3. Main material for handling
4. Alumina(Al2O3), Zirconia(White/Black ZrO2),
5. Silicon nitride(Si3N4), Silicon carbide(SiC), Aluminum nitride(AlN), Porus ceramic (White/Brown/Gray)

CAMERA MODULE BONDING TOOL

During the production process of camera modules for mobile phones, the Attach Bonding Tool used in bonding PCBs and image sensors ensures high yield and precision

1. Material : Alumina, AIN, Copper
2. Application : Pick-up and bonding tools for cameras module production.

• It guarantees uniformity and high precision without limitation of pocket shape
• The same performance for entry/exit of MLCC from all pockets
• High durability implementation with the use of BLACK ZIRCONIA (density 6.05 g/㎤) material (resistance to dimensions)
• High mechanical properties and abrasion resistance
• 21C Advantages: Fast delivery date/low price/excellent quality compared to competitors

21C has been supplying index tables of various specifications since it succeeded in localizing index tables used in the MLCC taping process.

Existing Index tables were limited in pocket size because they formed pockets with polishing methods, but 21C has been developing for years to produce pockets without limitation in pocket size.

Since it was developed, it became possible to respond to smaller sizes than the recent 0201.

21C’s unique Index Table production method provides high quality stability and precision, so it rewards customer's stable production activities in the MLCC field with the best quality.

MLCC INDEX TABLE

• Ensure uniformity and high precision without limiting pocket shape
• Same performance for entry/exit of MLCC generated from all pockets
• High durability implementation with the use of BLACK ZIRCONIA (density 6.05 g/)) material (resistance to dimensions)
• High mechanical properties and wear resistance
• Advantages of 21C: Faster delivery / Lower price / Excellent quality compared to competitors

INDEX TABLE FOR MLCC PKG

• Reduce noise when Pocket In & Out!
• Complete Protection of Minimum Time Between Interrupt!
• Cost Down effect due to localization!

21C has succeeded in localizing Bonding Tools for HBM, which relies on Japanese imports, and is producing and supplying them to clients.

This product requires ultra-precision processing technology and polishing technology of hard metal and PCD, and it requires the best processing technology to maintain a high-precision plan of 2um even at a high usage temperature of 400℃.

It is not a product consisting of an imported S45C body and a PCD hard metal, but a product consisting of an integral body and a PCD attachment, and produces and supplies a long-lived COF bonding tool without deformation.

• We customize tools as per the clients  needs.
• Unlock many benefits by partnering with 21Century (we also provides services internationally)
• Delivery of the tools before the ETA
• We provide the longevity of your tools
