TSMC's LED lighting technology research and development and mass production plant officially started, proclaiming TSMC officially stepping into the LED industry to divide the pie. Entering the LED industry and focusing on a new generation of solid-state lighting will replace traditional lighting with the demand for energy saving and carbon reduction. Experts pointed out that in the future when the LED lighting era is officially coming, the demand for LED will be 50 times of the current LED production capacity, 150 times that of mobile phone applications. However, the current product yields that meet the LED lighting standards are only three to four percent. The addition of TSMC is expected to raise the level and status of Taiwan's LED industry.
TSMC entered the LED industry, and market participants couldn't help but ask, with TSMC's foundry up to 45-50% of the gross profit, compared with only 20% of the gross profit of LED and solar energy, why choose to cross the relatively low-margin LED industry? In this regard, Zhang Zhongmou, chairman of TSMC, refuted the market view with the view that "TSMC will not only make a small profit." Zhang Zhongmou said that it is not fashionable to cross the LED and solar energy, but there are high-margin business opportunities.
TSMC has been focusing on the field of twin crystal for a long time, and the layout of the LED industry will also start from this. The preliminary plan of TSMC will be cut from the rear of the LED, from light source processing, electric drive to thermal module, etc., all integrated on the silicon wafer. TSMC said that the wafer substrate has a comparative advantage in standardization mass production, and the heat dissipation is three times that of the ceramic substrate. In addition, it has the advantages of high accuracy and high reliability.
Based on patented semiconductor processes and microelectromechanical precision fabrication technology, TSMC uses silicon wafers as packaging substrates to integrate light, electricity and heat treatment components, in addition to smaller size, lighter weight and less stress problems. In addition, the heat dissipation performance is also faster, thus greatly improving the luminous efficiency.
In addition, TSMC is also different from traditional modules and packages. It is manufactured in a semiconductor process. It does not require mold opening and the line width control is accurate. A large number of standardized production can be carried out, and the cost is naturally greatly reduced. In addition, the luminous efficiency is improved and the life is extended. The cost is even cheaper than existing light sources, and the competitiveness of LED lighting will naturally expand indefinitely.
Toaster, is a commonly used kitchen supplies, mainly used to bake bread. A toaster usually includes a multi-functional oven, a heat-insulating surface, a special lifting device, etc. The more advanced also includes a separable breadcrumb chassis. The toaster is a heating appliance. Its function is to generate enough heat in the vicinity of the bread to bake the bread. If there is no pop-up toaster, breakfast will certainly not be so rich nowadays.
In many families, the toaster is more prone to failure than any other small home appliance. There are two reasons for this. First of all, the toe machine manufacturing costs are generally very low, its quality is not high. You can replace a new device with just $ 10.
Second, the toaster is often not a problem when their own failure, but the food particles interfere with its normal operation. If there are too many slices of bread on the bracket, they will fall into the bottom of the toaster and accumulate when the movement of the tray will move up, thus hindering the movement of the bracket, causing the heating element to short circuit, Open the device and affect the function of the spiral tube.
Most of the pop-up toasters are equipped with a large debris plate and have a door at the bottom, the reason for this. By sliding or opening the broken door, you can clean up the food particles that accumulate at the bottom of the toaster.
