We utilize advanced technologies in the manufacturing of our products. To satisfy the needs of our OEM customers we stay abreast of advancements in technology, upgrading the technologies used in production to maximize flexibility in product design, increase quality levels, and minimize production costs.

We utilize the following production techniques:

CHIP ON FILM, OR COF, is an assembly method for bonding integrated circuit chips and other components onto a flexible printed circuit. This process allows for greater compression of the size of a product when assembled enabling the production and miniaturization of small form factor devices like cellular phones, PDAs, digital cameras and notebook PCs. As of December 31, 2006, we had 16 COF machines. These machines connect the bump of large scale integrated, or LSI, driver onto FPC pattern with anisotropic conductive film, or ACF. These COF machines have the ability to pitch fine to 38 micrometers and a total production capacity of up to 4,400,000 chips per month.

CHIP ON GLASS, OR COG, is a process that connects integrated circuits directly to LCD panels without the need for wire bonding. We apply this technology to produce advanced LCD modules for high-end electronic products, such as cellular phones and PDAs. As of December 31, 2006, we had 23 COG lines in our principal manufacturing facilities. These machines provide an LCD of dimension of up to 200 millimeters (length) x 150 (width) x 2.2 (height), a process time of five seconds per chip, a pin pitch fine to 38 micrometers and a total production capacity of up to 4,200,000 chips per month. During 2005, our subsidiary, Jetup Electronic (Shenzhen) Co. Ltd., or Jetup, also started manufacturing COG LCD modules. As of December 31, 2006, Jetup had nine COG lines and is capable of bonding 2,500,000 pieces of COG LCD modules a month. They are able to bond LCD panels up to sizes of 200 millimeters x 200 millimeters x 2.2 millimeters thick, with an accuracy of five microns’ tolerance, in a cycle time of 12-15 seconds per piece.

CHIP ON BOARD, OR COB, is a technology that utilizes wire bonding to connect large-scale integrated circuits directly to printed circuit boards. As of December 31, 2006, we had 51 COB aluminum bonding machines which provide a high speed chip bonding time of 0.25 second per 2 millimeters wire, a bond pad fine to 75 micrometers and a total production capacity of up to 3,000,000 per month. We use COB aluminum bonding in the assembly of consumer products such as calculators, personal organizers, linguistic products, meters and car audio products. We also had two COB gold ball bonding machines which provide a high speed chip bonding time of 0.072 second per 2 millimeters wire, a bond pad fine to 50 micrometers and a total production capacity of up to 300,000 per month. We use COB gold ball bonding in the assembly for digital still camera, mobile phone and digital pen products.

OUTER LEAD BONDING, OR OLB, is an advanced technology used to connect PCBs and large-scale integrated circuits with a large number of connectors. We use this technology to manufacture complex miniaturized products, such as high-memory PDAs. As of December 31, 2006, we had three OLB machines. The machines include multi-pinned tape carrier packaged large scale integrated circuit, or TCP LSIC, bonding which is up to 280 pins, which also provide ultra thin assembly with module thickness to around one millimeter and high accuracy bonding with pin pitch to 100 micrometers. The total production capacity is 12,000 units per month.

TAPE AUTOMATED BONDING WITH ANISOTROPIC CONDUCTIVE FILM, OR TAB WITH ACF, is an advanced heat sealing technology that connects a liquid crystal display component with an integrated circuit in very small LCD modules, such as those used in cellular phones and pagers. As of December 31, 2006, we had 27 systems of TAB with ACF machines. The machines provide process time of 10 to 25 seconds per component, a pin pitch fine to 200 micrometers and a total production capacity of up to 4,820,000 components per month. During 2005, Jetup also started manufacturing TAB LCD modules. As of December 31, 2006, Jetup had four TAB lines and is capable of bonding 500,000 pieces of TAB LCD modules a month. They are able to bond LCD panels up to sizes of 120 millimeters x 120 millimeters x 2.2 millimeters thick, with an accuracy of 10 microns’ tolerance in a cycle time of 20-25 seconds per piece.

FINE PITCH HEAT SEAL TECHNOLOGY, OR FPHS TECHNOLOGY, allows us to connect LCD displays to PCBs produced by COB and outer lead bonding that enables very thin connections. This method is highly specialized and is used in the production of finished products such as PDAs. As of December 31, 2006, we had eight machines utilizing FPHS technology. The machines provide a pin pitch fine to 260 micrometers and a total production capacity of up to 268,000 units per month.

SURFACE MOUNT TECHNOLOGY, OR SMT, is a process by which electronic components are mounted directly on both sides of a printed circuit board, increasing board capacity, facilitating product miniaturization and enabling advanced automation of production. We use SMT for products such as electronic linguistic devices. As of December 31, 2006, we had 33 SMT productions lines. The production time per chip ranges from 0.06 second per chip to 0.8 second per chip and high precision ranging from +/-0.05 millimeter to +/-0.1 millimeter. The components size ranges from 0.6 millimeter (length) x 0.3 millimeter (width) to 55 millimeters (length) x 55 millimeters (width). Ball grid array, or BGA, ball pitch is 0.5 millimeter and ball diameter is 0.2 millimeter. Flip Chip, our smallest lead/bump pitch, is 250/240UM. The total production capacity is 910,000,000 resistor capacitor chips per month.

SUPER-TWISTED NEMATIC LCDS, OR STN TYPE LCDS, capable of providing higher information content display systems are found in applications such as cordless phones, mobile phones, MP3 players, pocket games and PDAs. J.I.C. group started producing STN LCDs in 2002. During 2005, J.I.C. group update its two existing twisted nematic, or TN type, LCD lines to STN LCD lines. As of December 31 2006, J.I.C. group was equipped with three automated STN lines capable of producing both TN and STN type LCDs with capacity of 150,000 pairs of glass (each sheet of glass of 360 millimeters x 400 millimeters size) panels per month.

LCD BACK-END is a main manufacturing process for LCD panels, and is regarded as part of the process for its finished product LCD modules. It includes the precise pure water cleaning process, scribing of LCD glass, liquid crystal insertion, sealing process and breaking process, then turns the LCD mother glass into LCD panels. Our machines can cope with 0.2 millimeters + 0.2 millimeters LCD mother glass up to dimension 550 millimeters x 670 millimeters, with cutting tolerance +/-0.1 millimeters. Nam Tai started mass production from September 2006, with monthly maximum production capacity of 1,800,000 units.

As of December 31, 2006, we had five clean rooms at our principal manufacturing facilities, which housed COB, COF and COG capabilities for CMOS sensor modules, electronic calculators, digital camera accessories, LCD modules and front light or back light panels manufacturing. We also have four clean rooms at another of our factories, which are used to manufacture LCD panels and modules. Of our ten clean rooms as of December 31, 2006, four were class ten thousand, five were class thousand and one was class one hundred.
