34. The production of PCB should pay attention to what?

In Electronic Infomation Category: 3 | on October 19,2011

The production of PCB should pay attention to the following matters:

(1) a reasonable partition the circuit board, such as the strong, weak signal, digital, analog signals. As far as possible interference sources (such as motors, relays) and 34 datasheet and the sensitive components (such as SCM) away from.

(2) and 34 price and high-power single-chip device to separate down to the ground, to reduce mutual interference. High-power devices on the edge of the board as possible. Separation of digital and 34 suppliers and analog.

(3) to give the single-chip power supply of filter circuit or regulator, generally beads, 100 Q resistance can also be used instead.

(4) note that the crystal wiring. Crystal to the microcontroller pins as close as possible, land line to isolate the clock area, crystal shell ground and fixed.

(5) wiring to avoid 90. Line, to reduce high frequency noise emission.
