PCBA is the abbreviation of Printed Circuit Board Assembly. PCBA manufacturing is the process of attaching electronic components to a Printed Circuit Board by SMT production and through hole assembly. This process involves a combination of automated and manual tasks such as soldering, surface mount technology (SMT), through-hole technology (THT), and quality inspection. PCBA manufacturing is an essential step in electronic devices.

There are two main types of PCBA manufacturing: Surface Mount Technology (SMT) and Through-Hole Technology (THT).

Surface Mount Technology (SMT) Printed Circuit Board SMT assembly is a circuit assembly technology that solders components to the surface of a Printed Circuit Board by reflow soldering or dip soldering. SMT PCBA manufacturing is typically used for compact, lightweight, and high-density electronic devices, such as smartphones, tablets, and laptops.

Through-Hole Technology (THT)

Through-hole Printed Circuit Board assembly also named DIP involves inserting electronic components through pre-drilled holes in the PCB, and then soldering the leads to the other side of the board. Through-hole Printed Circuit Board assembly is used for heavy-duty electronic devices, such as industrial equipment and high-end audio gear.Most electronic devices are the combination of both SMT and THT assembly methods to achieve a balance between size, weight, and durability.
