PCB assembly consists of many steps. For PCBs with through-hole components, the assembly is quite easy. But for SMT components, elements are placed on the conductive pads with previously applied solder paste that holds the SMT parts together. Then the components are soldered to the pads. Due to the ever-growing demand for high-density circuit boards and smaller SMT components, defects during the PCB fabrication process increase. Thus, a thorough inspection is necessary at many stages of the fabrication process. PCBGOGO is a leading specialist in surface-mount, thru-hole, and mixed technology PCB assembly and electronic manufacturing services, as well as turn-key electronic PCB assembly. PCBGOGO is highly specialized not only in quick-turn PCB prototype and PCB assembly, but also medium and small volume PCB fabrication.

The assembly process at PCBGOGO consists of various inspection and functional verification stages to ensure that the requirements are completely satisfied. During the initial PCB manufacturing process, all the components are inspected by their IQC Department. Before chips are mounted on the PCB, IC programming service is also present. It is usually done by using a computer as a bridge for IC programming. After assembly, functional testing is done by software to ensures that the requirements are satisfied by the application. At PCBGOGO, all PCBs are tested for quality and correctness before shipping.

PCBGOGO team says,

We guarantee that all our PCB products meet industry standards and undergo rigorous testing before delivery.

During PCB fabrication, AOI (Automated Optical Inspection) is a crucial process. It ensures that the PCBs leaving the production line are without any manufacturing defects. This inspection is used in PCB fabrication and PCB assembly, as well as testing printed circuit boards.

Automated optical inspection (AOI) is an automated visual inspection technique for printed circuit board manufacturing where a camera autonomously scans the device under test for both catastrophic failures and quality defects. The inspection technique can detect faults like missing components, components skew, surface defects, dimensional defects, etc. AOI is a machine-based technique as the accuracy required for the inspection is impossible via manual checking. This inspection tool increases the product quality in the production line at a low cost.

Compared to the traditional manual inspection method where technicians need to look at every component and mark them one by one, the AOI inspection method offers high accuracy. Moreover, the manual inspection is time-consuming work, whereas AOI only needs one minute to run through the whole board. Thus, AOI inspection method is accurate, reduce labor cost and time cost greatly.
