Japan Earthquake Affected International Manufacturing Supply Chain – iPad2 Has Cut

Reloaded from http://www.partsparty.com/?p=449
Japan’s eastern coast from the strong earthquake occurred in 9 of more than half a month has passed, but the earthquake damage is still spreading, equipment damage and power shortage on the Japanese company to resume production quickly create great obstacles, their impact is also important to quickly spread to Japan link point of the global manufacturing chain.
Japan’s earthquake disaster caused damage to a number of business equipment, coupled with Japan’s plans to take measures to deal a serious setback power supply capacity, difficulties encountered enterprises to resume production. Components can not deliver on time, assembled into finished products without straw, not only affect Japan’s domestic production, which is also 10% of the key components imported from Japan, the Japanese rely on overseas factories facing difficulties with the Japanese companies have supply and demand of many international companies are inevitable compromised.
Globalization, manufacturing supply chain can be said to affect the situation as a whole. For example, Japan is the world’s automobile industry an important part of the industry chain, Europe, Asia, auto makers had felt from the moment “in Japan” cut and cut a “shock.”
According to U.S. research firm IHS25 released survey data, due to sharp drop in production in Japan, imported from Japan on time delivery of parts can not be expected worldwide vehicle production cut to 600,000 by the end of March. If Japan can not resume normal production, two months after the earthquake, the worldwide auto production could fall 30%.
According to Japan, “Asahi Shimbun” reported that due to import spare parts from Japan in trouble, General Motors had to face some knock-on effect. Its located in a small Louisiana truck plant 21, were forced to stop, and then provide them a New York engine plant had to lay off 59 people. General Motors in Spain and Germany also temporarily suspend part of the plant.
According to Kyodo News and the “Japanese Economic News” and other media reports, Ford Motor Company has a full cessation of 25 black and red passenger car orders because of difficulties in paint imported from Japan. As imports from the electronic components Hitachi be obstacles, the French PSA Peugeot Citroen Group in the European diesel engine production line has also been directly affected.
Japan’s neighbors South Korea of ​​Japan’s imports in 2010 amounted to 64.3 billion U.S. dollars, mainly imported parts and raw materials. Since the transmission from Japan stocks dropped, Renault Samsung Motors plant in Busan, the date of cancellation from 18 to work overtime, Saturdays production.
Affected by the earthquake in Japan as China’s Dongfeng Motor Co., Ltd. Dongfeng Nissan Passenger Vehicle Company is currently declining dramatically. 26 factories located in Xiangfan, the production plan has been arranged by one-third less than usual, into a semi-shutdown state. After the big earthquakes in Japan, as Japanese domestic production of engines, transmissions and other key components are not on product supply, Dongfeng Nissan to rely on inventory to maintain production.
In addition to the automotive industry, the Japanese earthquake on the impact of other manufacturing supply chains are gradually becoming apparent. According to “Asahi Shimbun” reported that the U.S. Apple Tablet PC iPad2 at least 5 manufacturers of electronic components from Japan, affected by the earthquake is difficult to deliver on time, especially its display only the products imported from Japan, so the possibility of production cuts great.
In addition, the world’s largest mobile phone manufacturer Nokia is due to the shortage of spare parts imported from Japan, part of the production line may be suspended production. Hyundai Heavy Industries, Samsung Heavy Industries shipbuilding steel plate needed, in the Japanese import “without food” situation, domestic steel companies have requested an emergency increase to meet their urgent needs.
Does Japan earthquake affect electronic components industry?

Application Information of UCC3808

A 200-kHz push-pull application circuit with a full wave rectifier is shown in Figure 2. The output, VO, provides 5 V at 75 W maximum and is electrically isolated from the input. Since the UCC3808 is a peak current mode controller the 2N2222A emitter following amplifier (buffers the CT waveform) provides slope compensation which is necessary for duty ratios greater than 50%. Capacitor decoupling is very important with a single ground IC controller, and a 1 μF is suggested as close to the IC as possible. The controller supply is a series RC for start-up, paralleled with a bias winding on the output inductor used in steady state operation.

Isolation is provided by an optocoupler with regulation done on the secondary side using the UC3965 Precision. Reference with Low Offset Error Amplifier. Small signal compensation with tight voltage regulation is achieved using this part on the secondary side. Many choices exist for the output inductor depending on cost, volume, and mechanicall strength. Several design options are iron powder, molypermalloy (MPP), or a ferrite core with an air gap as shown here. The main power transformer is a low profile design, EFD size 25, using Magnetics Inc. P material which is a good choice at this frequency and temperature. The input voltage may range from 36 V dc to 72 V dc.
