Summary of AOI IN PCB & PCBA MANUFACTURING PROCESS OF PCBGOGO
PCBGOGO provides turnkey PCB assembly and manufacturing services for SMT, through-hole, and mixed-technology boards, specializing in quick-turn prototypes and small-to-medium volumes. Their assembly workflow includes IQC inspection of components, IC programming before placement, soldering of SMT parts on solder-pasted pads, automated optical inspection (AOI) during fabrication, and software-based functional testing. All PCBs undergo rigorous inspections and testing to meet industry standards before shipment.
Parts used in the PCBGOGO PCB Assembly Project:
- Printed Circuit Board (PCB)
- Surface-Mount Technology (SMT) components
- Through-hole components
- Solder paste
- IC chips (integrated circuits)
- Programmer/computer for IC programming
- Automated Optical Inspection (AOI) equipment
- Testing software for functional verification
- IQC inspection tools and instruments
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.
