In which side of the PCB The components are mounted?
On the most basic PCBs (single-sided boards) the components are located on one side of the board and the conductor pattern on the opposite side. This requires holes in the PCB for the component legs to penetrate the board. Hence, the legs are soldered to the PCB on the opposite side of where the components are mounted.
What are the two sides of a PCB called?
(2) The Double-layer PCB is a circuit board with copper on both sides, usually called one side as the Top Layer and the other side as the Bottom Layer. Generally, the top layer is used as the component surface, and the bottom layer is used as the component soldering surface.
What do you call a double sided PCB?
Since, there are two or double conductive layer forming the circuit; it is called Double Sided PCB or Two Layer PCB. Both through-hole electronic components and Surface Mount Components (SMD) can be soldered on either side of this type of PCB. SMD components can be soldered with Surface Mount Technology.
How to mount SMD parts to bottom of PCB?
So from your Eagle toolbar, select the MIRROR command. After selecting the MIRROR tool, click on both C5 and C6 (make sure your top origin tOrigins layer is turned on).
Why are there holes on both sides of a PCB?
Conductive holes in the PCB allow circuits on one side to attach to circuits on the other side. Electronic components are soldered on both sides. Since, there are two or double conductive layer forming the circuit; it is called Double Sided PCB or Two Layer PCB.
How are THT components soldered on a PCB?
THT components are most often soldered in an automated process called ‘Wave Soldering’. This enables all components to be soldered simultaneously. Their legs are first cut near the board and slightly bent over to keep the component in place. The PCB is then moved over a wave of liquid flux, such that the bottom side strikes the flux.
