PCB Assembly

Surface-Mount Technology

Surface-mount technology (SMT) is an assembly process that involves mounting electronic components to the surface of a PCB. It is highly automated and flexible, and it allows for higher connection densities. It enables manufacturers to place complex circuitries into small components.

The four basic steps of PCBA SMT are:

Preparing the PCB: First, the assembler places solder paste where it is needed on board.
Placing the Components: Next, the assembler places the components on the board, typically using a pick-and-place machine.
Reflow Soldering: The assembler then heats the boards in a reflow oven until the solder paste reaches the temperature required for the solder joints to form.
Inspection: The assembler conducts inspections throughout the SMT process, including before attaching the components and before and after reflow soldering.

Thru-Hole Technology

Thru-hole technology is an assembly process that involves drilling holes into a PCB through which electronic components called leads can be attached. It is an older technology than SMT but creates a stronger connection between the board and the components, which makes for more durable and reliable assemblies.

Thru-hole assembly can be either fully automated or semi-automated. The steps of the PCBA thru-hole process include:

Drilling the Holes: The first step in the thru-hole process involves drilling holes into the board. These holes must be the right size for the component leads.
Placing the Leads: Next, the assembler places the leads in the holes.
Soldering: The next step in the process is soldering. This step ensures the components are held firmly in place.
Inspection: Throughout the process, the assembly undergoes inspections to ensure the PCBA will function as expected.
