Functional Testing and Other Testing

PCB Assembly testing mainly includes In-Circuit Testing (ICT), Functional Testing (FCT), Aging Testing, Temperature and Humidity Testing, Drop Testing, etc. It operates according to the customer's testing plan and then summarizes the report data.
We have high and low temperature test chambers, triaxial vibration test machines, drop test machines, shock and vibration test machines, salt spray test chambers, dust test chambers, UV test chambers, button durability test machines, RDS high-frequency signal generators, high-frequency digital oscilloscopes, audio analyzers and other advanced test instruments and analytical equipment.

The industrial monitoring system displays the real-time operating status of SMT assembly factory machinery. Through a combination of 2D panels and 3D models, specific data of the equipment is displayed, such as the number of scrapped parts, working time, number of pick-ups, and production output of pick-and-place machine; the number of good products, pass rate, and total production output monitored by the SPI; and the number of PCBs with misplacements and defects monitored by the AOI, ensuring the verification and control of the printing processes. The hourly yield of the production line is directly transmitted to the visualization platform. If the yield falls below the set target level, it will drive management to improve. By combining hardware and software, the "Internet + IoT + Big Data + Automation Equipment" are seamlessly integrated to form a self-driving effect. Non-standard operations will be alarmed.

PCB Assembly (PCBA) Process

365PCB has dozens of SMT production lines and state-of-the-art equipment.
We are committed to providing high-quality small to medium batch production services.

  • IQC Incoming Quality Control
    01. IQC Incoming Quality Control

    365PCB Verifying all incoming materials and handling quality problems before subsequent SMT assembly begins.
    ● Check whether the resistance and capacitance values are correct.
    ● Check whether the pads on the components and the board are consistent.
    ● Confirm whether the incoming quantity is accurate.
    ● Check whether the components are abnormal.

  • Solder Paste Printing
    02. Solder Paste Printing

    It’s a key part of the surface mount pcba process flow, applying solder paste to a printed circuit board (PCB), the most common option of applying solder paste to a PCB through a stencil printer.
    This process deposits accurately the correct amount and thickness of solder onto solder pads.

  • Solder Paste Inspection (SPI)
    03. Solder Paste Inspection (SPI)

    Solder paste inspection aims to find out the defective solder paste printing online in the Printed Circuit Board (PCB) assembly process. SPI can directly check the quality of solder paste on the PCB. With solder paste inspection, the defect rate can be reduced and a lot of cost and time can be saved.

  • SMD Component Placement
    04. SMD Component Placement

    Component placement is an electronic manufacturing PCBA process that accurately mounts surface-mounted components into fixed locations on a printed circuit board (PCBs) to establish electrical interconnections between the components and the PCBs.

  • Reflow Soldering
    05. Reflow Soldering

    The reflow soldering process uses solder paste to temporarily attach electronic components through their contact pads. After a long period of high temperature, the solder paste melts and the surface-mounted components are firmly adhered to the PCB board.

  • Automated Optical Inspection (AOI)
    06. Automated Optical Inspection (AOI)

    AOI can detect mis-soldering, reverse soldering, empty soldering, empty soldering, lack of penetration, short circuit, offset, tombstone, etc. after reflow soldering. It can also detect defects such as excessive welding, insufficient welding, and continuous welding in the appearance of PCBA solder joints.

  • Through-Hole Component Soldering
    07. Through-Hole Component Soldering

    PCBA through-hole component soldering is a critical step. Manual soldering is suitable for small batches and prototyping, providing flexibility and precision, but with low productivity. Wave soldering is suitable for mass production, has high efficiency and good consistency, but has limited component selection, requires preheating, and is costly.

  • First Sample Test
    08. First Sample Test

    Combined with Gerber, BOM and coordinate files, the resistance and capacitance in the completed PCBA are verified again by the first-sample tester to ensure the correctness of all parameter values.

  • X-Ray Inspection
    09. X-Ray Inspection

    X-ray inspection is typically performed on Quad Flat No-Lead (QFN) and Ball Grid Array (BGA) components during printed circuit board assembly, checking the solder joints of invisible components to ensure the reliability of each solder ball in the BGA.

  • Final Inspection and Functional Test
    10. Final Inspection and Functional Test

    The final stage of the PCB assembly process is conducting functional tests to verify that the PCB operates as expected. Additionally, depending on the application, there may be further requirements. For instance, automotive PCB might undergo drop tests, and medical PCB might require halogen testing.
