Soldering of electronic components on bare pcbs are also known as PCBA or printed circuit board assembly. Surface mount devices (SMDs) are usually placed on pcbs using a pick and place machine and then sent to reflow for soldering. Through hole components on the other hand are soldered on wave soldering process.
PCB manufacturing is a multi step process involving various electrochemcial process. Here is an article which explain the pcb process step-by-step.
PCB assembly cost depends on the number of components on board and the complexitiy of components. We have an automatic quote generator to order pcba online on our platform.
PCB or printed circuit boards are bare circuit boards which have electrical connections on the board from various electronic components without the components mounted.
PCBA is the printed circuit board with electronic components soldered on it.
