http://blog.csdn.net/guanyasu/article/details/52557810 Here are three ways to share your Altium Designer-painted component package. If there is any mistake, I hope you will correct me. First, manual painting. (1) Create a new PCB library. The following is an example of STM8L151C8T6, which is its encapsulation information Set the grid spacing (shortcut g), of course, can also be flexibly set in the design, introduce a shortcut key ctrl+q can be achieved between the mil and MM unit switching.

not supported, and I did not succeed in testing jdk7_13 and jdk7_21. Official website said it is based on JDK7-b102 compiled. I guess these two versions are incorrect. Java agent + Instrumentation 1. Spring-Loaded SpringSource is released on the official website. It is used in Grails 2 and allows: Add/modify/delete methods, fields, and constructors. Annotations on the Type/method/field/constructor can also be modified, and values of the enum type can also be added/deleted/modified. Usage:Java c

cleared, we need to pull it out. Use a tool to scrape the outer coating and weld it online, but never cut the A17 wire. Then weld another wire at the place indicated by the arrow. Connect the two wires to the switch. This step is complete. Use A multimeter to test whether the two wires just welded are short-circuited or connected together. Then confirm that the switch is closed. If you open your

), and the dormitory of the other three big God also not very familiar, so all day holding a mobile phone toss. Later heard that there are departments recruit new, so from a big cock silk temperament I wore shorts slippers went to the interview, you guessed right, was the interviewer, this is the first interview AH (╯﹏╰), feel wet chest good fierce! After four years, the university did not participate in any department, this is a university career a great pity.Later from Xiang Brother where hear

Since the first set of mechanical keyboard, has modified the interface scheme, installed LED lights, etc., but always can not meet their DIY desire.So the simplest way to think of it is to use a ready-made master, and the master comes from an abandoned keyboard, such as:This master control is also the matrix mode, only need to measure the corresponding key and then weld the line, complete the diagram as followsUsing the O 5-foot red axis mechanical sh

focus of a laser beam is small, and the power density is high. It can weld some alloy materials with high melting points and high strength. Laser Welding has no contact processing, tool loss, tool replacement, and other problems. Adjustable laser beam energy, adjustable movement speed, multiple welding processes. High degree of automation of laser welding, can be controlled by computer, fast welding speed, high efficiency, can easily carry out any

Online segment level editing (segment ): Use the line segment attributes a, curve (curve), B, line (line) Edit at the level of the spline(Sub-object à spline) (1) closed spline (close) (2) create an outline for a spline) (3) Boolean operation: This command combines two source splines. (4) image (mirror) spline st

necessarily the previous winmain and Main, which are described in C ++ from scratch (19th.For subsequent instructions, you should know that the program starts to run from the main function, as follows:Long A; void main () {short B; B ++;} Long C;The preceding statements actually start with long A; and long C;, but you don't have to worry about them. Actually, meaningful statements start with short B. Function) The robot is used to weld the welding po

Common failure One: unable to find the mouse 1. The mouse is completely damaged and needs to be replaced with a new mouse. 2. Mouse and host connected serial port or PS/2 mouth contact is bad, carefully connect the line, restart can be. 3. The serial port or PS/2 port on the motherboard is damaged, this situation is very rare, if this is the case, have to replace a motherboard or use the serial port on multi-function card. 4. Poor contact with the mouse line, this situation is the most commo

broken feet, the right hand with electric iron quickly welded together. Some rosin can be used to make the solder joints small and smooth. (4) The CPU is carefully inserted into the CPU socket, if inserted, can be used to weld the blade carefully trimmed, inserted after the boot, all normal, finished! 　　Method Two: Direct connection method (1) Take 30 cm long diameter of about 0.2 mm of enameled wire, with the same method as above to

than 2m, it should be placed around the ground with salt 8kg, about 30kg of wood carbon and add water to reduce the grounding resistance. If 2 and more than 2 grounding poles are used, the spacing between poles is less than 0.5m to reduce the Earth's diaspora resistance. In soils with strong corrosive behavior, copper or zinc-plated grounding electrodes shall be used. At the same time, grounding should not be buried in the garbage layer and ash layer area, laying in the ground of the earth shou

-0.27a, the power supply is 12v-1a, you can know that the power can fully drive this fan full-speed operation. And then we started to weld them together. Cut both the fan and the power connector directly How to weld the thread? Very simple, red welding red, black welding black, OK. In addition, direct the fan white line (temperature control) cut off, because we do not need any "tempera

pulled forcibly pull the reason, the solution is to open the mouse, and then use the electric iron will weld spot welding well. There is also a situation is the mouse line internal contact is bad, due to the long time caused by aging, this fault is often difficult to find, replace the mouse is the fastest solution. Second, the mouse can show, but can not move The mouse's flexibility drops, the mouse pointer is not as arbitrary as before, but unresp

needs to have a debugging order. In short, generally starting from the power supply, we must first ensure that the voltage of each file is normal. Secondly, we need to weld the crystal oscillator and reset circuit, FPGA and download circuit, and then perform board-level verification, ensure that the configuration circuit and Device of FPGA work normally, and finally weld other peripheral circuits. 6.Ther

thick, as long as the time is extended, suitable for bonding boards. the chances of e-gold potion waste are smaller than that of gold. however, the electric Fund requires full-board conduction, and is not suitable for very small lines. gold is usually very thin (less than 0.2 microns), the purity of gold is low. work fluid can only be discarded to a certain extent The circuit board of a gold board has the following features: 1. the scalability of the gold board is equivalent to that of the OSP,

This article is the author's graduation thesis and his own code; Simulation Software Design of automatic batching system for Welding Electrode Design Content Welding rods are widely used in steel structures in construction and industry. A electrode can be divided into solder and solder. Solder is a steel rod with a specified material, length (about 400mm), and diameter (about 5mm). solder is a chemical coating on the solder. Figure 2 and Figure 3 show the two electrode types downloaded from the

; fully compatible with the WINDOWS9X-2000. There are only a few buttons: Open File (send), read chip (read), exit (exit), com selection, lock code, and check (fast verily ). You will know it at a glance. Note that the upgraded version ez4.0 is now available for automatic monitoring of port numbers and chips. Easy to use!DIY installation steps:1: Installation resistance, a total of 11; component inserted in place after welding shear pin:2: Install diode, three 1n4148 and one 12 V voltage regulat
