Integrated power module on the attempt

Integrated type power module is considered to be China's manufacturers now weaknesses, because it needs large investment, and the main chip system closely, a higher technical threshold. However, there are ShiLan etc manufacturer has set up a file in the attempt.

"Because of IPM module involves high integrated circuit, high performance power device chip, high reliability of the packaging technology, because this is in our country development is relatively slow, at present the market also basically by foreign brand companies over." The ShiLan WuJianXing said. IPM module (commonly known as intelligent power module), in all kinds of power transformation, power drive system has a wide range of applications, generally speaking, IPM module internal integrated many star power device chip (such as IGBT, MOSFET, FRD, etc.) and high voltage driving circuit, etc., are greatly simplified the machine assembly complexity and to reduce the cost of assembly, reduce the volume of the engine and improve the reliability.

WuJianXing think, because see IPM module in frequency conversion motor drive, integrated power supply and other areas of application for a sustained, rapid growth, the domestic many manufacturers into the related technology development; Based on today's chip technology and packaging technology progress, believe IPM market application will soon have a breakthrough.

ShiLan microelectronics use have mastered the core technology of plane high VDMOS, IGBT, fast recovery diodes power device chip ability and high pressure integrated circuit chip ability, investment form the chip high voltage power module manufacturing line. Power module that dozens of discrete element integrated into a single sealants body inside, and integration of real-time abnormal reaction, the protection of both the high insulation and high thermal conductivity, frequency conversion motor controller is the most important devices in its reliability, efficiency and volume has very obvious advantages. ShiLan microelectronics has the research and development of integrated power module, such as SD04M50 power module integrated six 500 v / 4 a ESD protection with low switching loss MOSFET and three high and low side driven HVIC, mainly for the 150 w the following indoor and outdoor air conditioning fan variable frequency drive and three-phase brushless dc fan drive. The most frequently SD20M60 power module integrated six 600 v/and a IGBT, 6 fast recovery diodes, three high integrated circuit (HVIC), 3 bootstrap diode and a low pressure integrated circuit, mainly for the 1500 w air conditioning compressor under variable frequency drive and industrial sewing machine, spinning machine, variable frequency drive.

"ShiLan microelectronics power module internal all chip all develop their own manufacturing, power module parameters can be customized according to customer demand, to meet the local market just rise up and growing brushless dc is changed, speed frequency change request." WuJianXing said. "ShiLan microelectronics power module in impact resistance, resistance to noise and heat dissipation performance is close to catch up with the international power companies and some similar products.

He said, the Japanese earthquake brings power device for out of stock, the international power giant power module production also is greatly limited the power module, resulting in serious shortage, but it also gives local power module to bring the opportunity. ShiLan microelectronic power module focuses on current conversion efficiency is still low but the market to be developed areas, such as a brush turn brushless, constant frequency transformation frequency of industrial and household appliance field. Through the power module custom and control scheme of guidance, by the customers.

Part of power IC manufacturers delivery date and the Japanese earthquake influence

Hangzhou ShiLan microelectronics: nearly a year and a half since, because in the industrial electronics and consumer electronics products continue to grow, the application of power semiconductor the entire market demand to rise sharply, including international manufacturers, suppliers all appeared capacity is insufficient, the market in short supply situation. In the face of the whole market capacity shortage problem, ShiLan micro hand greatly expanded capacity, and at the same time, improve the production management ability, and constantly reduce each procedure processing cycle, will existing equipment capacity utilization to perfection; On the other hand, strengthen and customer communication, according to the customer demand arrangement, so that to ensure the feed production resources optimization. At present IC delivery time for three months, MOSFET delivery time for two months, the basic belong to normal.

Wuxi core friends microelectronics: we currently have no capacity to meet, we in the system the customer delivery time control in less than two weeks.

Core union semiconductor company: we recently in the flow sheet and packaging have some capacity shortage problem, so far, our company mainly USES the off-season much stock up plan. So far, our company flow sheet delivery in the days or so, package delivery in 45 days or so.

Fai mans microelectronics: we didn't meet capacity shortage problem. We usually delivery for four to six weeks.

The into microelectronics: at present the into micro is in rapid development stage, there is no meet capacity shortage problem. Usually delivery cycle 30 days. The into micro is how to do it? The following reasons: 1, for the next three months of market demand accurately estimate, in wafer aspects do sufficient inventory; 2, the measurement/packaging/measurement/logistics as the key link for reasonable and effective arrangement, to shorten the delivery time. 3, request agent reasonable stock up in advance, support customer urgent single.

BCD: from far, don't feel Japan earthquake brings about the influence of capacity.

Beijing think prosperous: we are not affected. We have cooperation with some foundry for 5 years, have very good cooperation relations, and we will be given in advance demand forecasting, foundry will give we reserve capacity, to ensure the delivery time. Usually we chip delivery cycle is six to eight weeks.
