Description
Solder pads and wires on PCB
The element is fixed on the printed circuit board, which is made by welding electrodes to a welded plate. The electrical connection between components depends on printed wires.
1. The welding plate: components through the pin holes on the board, mounted on printed circuit boards with solder welding, printed wire bonding pad have rise, implementation components in the electrical connection in the circuit. The wiring holes and the copper foil around them are welded.
2. Strike and shape of the printed wire: it is naturally preferable that the guide wire shall be printed, which is generally rounded, and the right Angle or included Angle may affect electrical performance in the high frequency circuit.
3. Width of printed conductor: the width of printed conductor can generally be estimated according to 1A/mm. When the power cord and the ground wire are designed, they should be widened appropriately, usually 1.5-2.0mm. If allowed, ground line width > power line width > signal line width. Wide signal lines can be used when the resistance and inductance of the printed circuit board is required. The distance between the lines is usually 1 ~ 1.5mm. Should try to avoid wire cross, if encounter is inevitable, can use jumper length (no more than 25 mm).
Component sub-assembly
1. Needle-type packaging (THT), the component pin will pass through the central hole of the pad through the PCB board at the time of installation, and the properties of the pad Layer are Multi Layer.
2. Tabbed packaging. Pin is attached to the surface of PCB board
