According to Taiwan’s “Economic Daily†report, “SEMICONTaiwan II???? Seven Taiwan Semiconductor Equipment and Materials Exhibition†was held in Taipei World Trade Center 1 and Hall 3 for three days from the 12th. There are more than 750 manufacturers this year. Exhibitors have created the highest record of exhibitors in recent years.
The organizer of SEMI, Meyer, pointed out at a press conference on the 11th that due to the driving of consumer electronics, the semiconductor industry is facing an important change, including cost adhesion and innovation-oriented applications, including die attach, wire bonding, packaging, etc. Technology continues to develop towards advanced processes.
Meyer stressed that although the absolute output of the chip has been rising over the past five years, the unit price has been decreasing due to consumer electronics. The current price of IC is lower than the average price of the second semiconductor. US$52 billion, a slight increase of 1.6% over last year’s US$248 billion, but the total semiconductor equipment and purchases will increase by US$82 billion due to advanced processes. In Taiwan, the total investment in semiconductor equipment and materials in the second seven years will reach US$16.6 billion, second only to Japan, becoming the world's second largest semiconductor equipment material. The pressure is increasing NEDO will entrust the development of organic EL lighting to three companies. The British Football Club will provide lighting with wind power. The World Bank will launch the African lighting program to promote the popularization of the wide-format laser/LED hardware shipments in 2010. 44,450 ABB signed with Kenya Power and Lighting. contract

Bare aluminium conductors have several advantages over other types of conductors. Firstly, aluminium is lighter than copper, which makes it easier to handle and install. This is particularly important for overhead power lines, where the weight of the conductor can have a significant impact on the cost and feasibility of the project.
Secondly, aluminium has a higher conductivity-to-weight ratio than copper. This means that for a given weight, aluminium conductors can carry more current than copper conductors. This makes them more efficient in terms of power transmission.
However, bare aluminium conductors also have some disadvantages. One major drawback is their lower mechanical strength compared to copper conductors. This makes them more susceptible to sagging and stretching under the weight of their own span, especially in hot weather conditions. To address this issue, aluminium conductors are often reinforced with steel strands to improve their mechanical strength.
Another disadvantage is that aluminium has a higher resistance than copper, which can result in higher power losses and voltage drops. To mitigate this, aluminium conductors are typically designed with larger cross-sectional areas compared to copper conductors to compensate for the higher resistance.
Overall, bare aluminium conductors are widely used in electrical power transmission and distribution systems due to their cost-effectiveness, lightweight, and high conductivity-to-weight ratio. However, careful design and installation considerations are necessary to ensure their mechanical strength and minimize power losses.
Stanley T. Myers, president and chief executive of the International Semiconductor Equipment Materials Industry Association (SEMI), said on the 11th that global 12-inch wafer output will grow 59 percent year-on-year this year. Twenty-nine percent. Among them, Taiwan will surpass South Korea for the first time next year, becoming the largest producer of 12-inch wafer capacity. Analysts believe that the island's solar radiation, silicon products, Licheng, Jingyuan Electric and other back-end packaging and testing plants will benefit the most.
