check and DRC check are correct, the uncabled area should be ground filled and a large area copper layer should be used as the ground wire, on the Printed Board, the unused parts are connected to the ground as the ground. Or make a multi-layer board, power supply, ground each occupies a layer.
-- PCB wiring process requirements
①. Line
Generally, the signal line width is 0.3mm (12mil), and the power line width is 0.77mm (30mil) or 1.27mm (50mil ); the distance between the wire and the
() function.PadPad is a special case of window. The pad can be larger than the displayed screen, showing only part of the pad at a time. Creating a pad is simple and requires only a wide height. But refreshing the pad needs to provide the coordinates of some pad displayed o
This article mainly introduces the repair method of toISOString is not supported by Date in IE6-8, friends can refer to the Date. prototype. toISOString method is added in ES5, ES3 document does not, as follows
This method is not supported in IE6/7/8. You can fix it as follows:
The Code is as follows:
If (! Date. prototype. toISOString ){Date. prototype. toISOString = function (){Function pad (n) {return n Return this. getUTCFullYear () +

On the capacitor encapsulation in addition to the above chip encapsulation, the non-polar capacitor, its encapsulation model also has rad type, such as "RAD-0.1" "RAD-0.2", etc, the suffix number indicates the distance between two pad in the encapsulation
The member systems of many projects require the remember login function. the Function of using cookies is to directly store customer information to cookies, if you write cookies directly, security risks are inevitable. Therefore, if you store cookies after reversible encryption, the function source code is secure.

Remember I was involved in the development of a Huawei project that requires programs to support several terminal devices, including the Android phone and the Android Pad. Then, in order to save people, the company's rogue to let the Android phone and Android pad are developed by our team. At that time, the project team decided to make two versions of the app, a mobile phone version, a

When the "waist acid back pain foot cramp", we can not expect every time to take the cover of the cover card high calcium to solve the problem. After all, to find the root cause, as a programmer, sitting on the job every day, it is easy to develop the habit of hunched. So, we have to use the kille

crystal oscillator must be grounded, the outward radiation of the crystal oscillator, and the interference of the external signal to the crystal oscillator can also be shielded.
5. Do not wire under the crystal oscillator, to ensure full paving, while in the Crystal Oscillator 300mil range do not wiring, this can prevent crystal interference other wiring, devices and layer performance.
6. Clock signal traces should be as short as possible, the line is wider, in the wiring length and away from
