    Product Description

    Technical & Capability

    PCB Assembly or PCBA is a crucial process in electronics manufacturing. It involves mounting and soldering components onto a printed circuit board (PCB).

    What is SMT?

    Surface Mount Technology (SMT) is a method of assembling electronic circuits where components are mounted directly onto the surface of a PCB. This method involves using surface-mount devices (SMDs) such as resistors, capacitors, and integrated circuits. These components have small metal tabs or leads that are soldered directly onto the surface of the PCB.

    Advantages of SMT:

    One of the biggest advantages of SMT is that it allows for smaller and more compact PCB designs. SMT components are much smaller than their through-hole counterparts, which makes it possible to pack more components onto a smaller board. This is especially important in applications where space is limited, such as mobile phones, laptops, and other handheld devices.

    Introduction to our 4L PCBA Module:

    Our 4L PCBA Module, Model No. PCBA-A28, is a communication board that uses a combination of SMT and Post Welding assembly methods. This allows us to take advantage of the benefits of both methods and create a board that is small, compact, and strong. The board has a 4-layer design, with a dimension of 90mm*90.4mm, and a thickness of 1.8mm. It uses FR4 as the base material, with a copper thickness of 1.0oz. The board is finished with ENIG, and the solder mask color is green, with white legend color.
