PCB assembly processing requirements about the fundamental principles
1.PCB layout style of the style and design, from the beginning to discover the length and width the board, pcb how large the shell by reason of chassis size limit, to be secure directly into enclosure is proper, and secondly, should think about the pcb and external components (mainly potentiometer, jack, and also other pcb) is connected. Pcb and external components are by and large isolated by plastic or metal wire cable. But sometimes designed socket form. Namely: setting up a computer plug-in pcb socket store being the contact position.
Positioned in the PCB layout design for this larger components, PCB design to supply metal attachment fixed to boost the possible vibration and impact resistance.
(2) sort of the essential technique of wiring diagram
First, selecting a components deparately needed for numerous devices and socket specifications, dimensions, area, which are usually fully understood; keeping the various components of a particular reasonable, careful consideration, mainly among the electromagnetic compatibility, interference way of thinking, traces short, cross-less, power, ground path and decoupling besides other considerations. Location inside the components set, the various with the line is, with regards to the pin connection diagram to try and do an array of methods, way of printed circuit diagram of computer-aided design and manual design method two.
One original is hand-arranged layout. This takes additional time, often repeated once or twice to finalize, which experienced before equipment can also be drawing, hand-arranged layout these method are merely learning PCB layout design is actually helpful. Computer-aided drawing, PCB assembly web site of graphics software, different functions, , in general, to draw in, modify, far easier and may save storage and printing.
