Rigid Lead Free HASL PCB Printed Circuit Board For Industry Assembly
Introduction of printed circuit board assembly (PCBA) process flow
Electrons are an indispensable part of our daily life.Everything from smartphones to cars includes electronics.At the heart of these electronic products are printed circuit boards, also known as PCBs.
Most people recognize a printed circuit board when they see it.These are small green chips covered with lines and copper parts that you can find in the heart of visceral electronics.The plates are made of fiberglass, copper wire and other metal parts, held together with epoxy resin and insulated with a solder resistance film.This solder resistance film is characteristic of where the green comes from.
But have you ever observed those components stuck?Never think of them as decoration on a PCB.An advanced circuit board will not be able to provide its functionality until the components are installed on it.PCBs with components are called assembly PCBs, and the manufacturing process is called PCB assembly or PCBA for short.Copper wires on the bare board (called trace wires) electrically connect the connectors and components to each other.They run signals between these functions, allowing the board to operate in a specially designed way.These features range from simple to complex, but PCB sizes can be smaller than thumbnails.
So how exactly are these devices made?The PCB assembly process is simple and includes several automatic and manual steps.Through each step of the process, the board manufacturer has manual and automatic options for you to choose from.To help you better understand the PCBA process from start to finish, we explain each step in detail below.

Two types of installation technologies are prevalent in the modern PCBA industry:
Surface mount technology: Sensitive components, some very small components, such as resistors or diodes, are automatically placed on the surface of a circuit board.This is called an SMD component and is used for surface mount devices.Surface mount technology can be applied to small size components and integrated circuits (ICs).For example, PCBCart can install packaging in minutes.Size 01005, even smaller than pencil point size.
Through hole technology: for components with leads or wires, they must be mounted to the board through holes inserted into the board.Additional lead sections must be soldered to the other side of the board.This technology is suitable for PCB components containing large components, such as capacitors, coils to be assembled.
