1. Murata Manufacturing Co., Ltd. has 13 factories in Hokuriku Prefecture, of which 8 have restarted production on the 9th. Among them, the production of piezoelectric products Toyama Murata, the production of MLCC Fukui Murata Takei business and Miyazaki factory, and the production of connectors Mackerie Murata, all quickly put into production after the earthquake.
2, Guangdong Micro Rong Electronic Technology Co., Ltd. is located in Luoding City, Guangdong Province, the main passive electronic components MLCC, is a major manufacturer of high-end MLCC in China.
3, hello, Guangdong Shenzhen big deep sensorIn the independent research and development of photoelectric sensor manufacturers.
The numbers on the back of ti chip are not as normal. According to the query of relevant information: the different letters behind the chip represent different meanings, generally speaking, a conventional chip model, is composed of letters, numbers, letters, behind these letters, numbers, representing different temperatures, parameters, and packaging.
Nvidia graphics card behind a ti to illustrate thisThe graphics card is manufactured using a titanium alloy process, and the performance is more robust, compared with the higher performance of 20-30% without ti. Graphics card model suffix: STD: Standard, standard edition. Usually you don't have to label it.
Personally, the batch number refers to the same batch of raw materials, but this batch of raw materials can produce products on many different days, otherwise it is necessary to use two numbers to manage why, just use the production date or batch number.
Price difference: When the graphics card was just released, the official price of the GTX750ti was 999 yuan, while the official price of the GTX750 wasPower or break the chip.
2, this dot method of identification is very common for dual in-line chips. This dot is the orientation point. The identification method is similar to the identification method with stripes. Lay the chip flat, with the first pin to the left of the dot and the last pin to the right of the dot. The pin number increases counterclockwise.
3, the direction of the word is the positive direction, equivalent to the gap on the left, from the lower left corner counterclockwise to the upper left corner of the pin number added one.
4, the capacity of Toshiba emmc chip in eMMC chipJust look it up in the data book.
5, high quality audio: Toshiba radio chip can provide clear, stable and high fidelity audio output, enabling users to enjoy a better sound quality experience. Powerful reception: Toshiba radio chips use advanced tuning technology to receive broadcast signals quickly and accurately, providing stable reception.
1, countermeasure: make maintenance plan on time, cleanMaintain the screw, slide rail, sticker head transmission mechanism, spring cleaning and other work, find the problem of parts timely replacement.
2, the program will be programmed into the computer smt mounter equipment, find the origin and make mark mark. The coordinates are corrected step by step, the saving procedure is optimized, and the component orientation and data are checked again. The first piece of the boot patch board is confirmed.
3, first check whether the material size of the program is set correctly and the height of the nozzle, whether the nozzle is worn, and whether the vacuum value is normal. Recheck that the feeder coordinates are not offset during the production transition (need to be periodically checked). Finally check the compressed emptyWhether the gas is normal (cleaning the solenoid valve, replacing the air pipe, recalibrating the air pressure).
4, the processing method of bulk material: first collect a certain length of used braid and a relatively thin plate. Then use double-sided tape to attach the braid to the plate, note: it is best to ensure that the position of the tank is aligned. Create a program that can use the Tray and enter the written information into the program.
