vga各针脚定义和焊接方法（VGA each pin definition and welding method） VGA each pin definition and welding method One, 15 pin VGA each pin definition: In accordance with the VGA (15HD) standard, the various pins are defined as follows: (PIN means feet) 1PIN -- Red -- the red of analog signals 2PIN -- Green -- the green of analog signals 3PIN -- Blue -- the blue of analog signals 4PIN - ID Bit, 5PIN - N/C, 6PIN - R.GND - the red earth terminal of analog signals 7PIN - G.GND - the green ground terminal of analog signals 8PIN - B.GND - the blue ground terminal of analog signals 9PIN - No.Pin, (backup) 10PIN - GND - the ground terminal of the sub signals 11PIN - ID Bit - the control or address code between the screen and the host 12PIN - ID Bit - the control or address code between a screen and a host (used for a host, multiple screens) 13PIN - H Sync - Digital horizontal field signal 14PIN - V Sync - Digital vertical field signal 15PIN - N/C - ground terminal Two 、 standard 15 needle VGA head welding method: The standard 15 pin VGA pin head as shown below (3+4 line, 3 said the 3 coaxial red, green and blue, 4 said 4 pieces of black and brown and yellow and white) VGA feet usually follow obtrapezoid, from top to bottom, from left to right are 1 - 5 feet, 6 10 feet, 11 feet, 15; (note that the D15 joint must use metal shell) as shown below: 15, we usually only need to weld 11 pins, as follows: (4, 5, 9, 12 feet are not welded) Red line - 1 feet - red of analog signals; The green line 2 foot analog signal green; Blue line - 3 foot - the blue of analog signals; Red line shielding line - 6 foot - analog signal red ground shield line; The green line outside the shielding line - 7 feet - green analog signal ground wire shield; Blue line shielding wire - 8 foot - analog signal blue ground shield line; Black line - 10 foot - the ground terminal of the sub signal; Brown line - 11 feet - the control or address code between the screen and the host; Yellow line - 13 foot - Digital horizontal li
