SMT代工

SMT service introduction:

Eliboard provides SMT processing services, our professional team builds complete PCB and PCBA quality control system. During the components soldering process, high-quality solder paste is used to ensure the reliability and stability of the welding. Our production line is equipped with automatic printing machine, high-speed placement machines, AOI automatic optical detectors, etc., which can effectively ensure the reliability and quality in the electronic packaging process. Regarding the SMT testing, we have professional engineers to implement preliminary planning, prevention, and monitoring. After the completion of the transaction, we review the quality management of improvement, standardization, and other aspects. We use various test fixtures to perform 100% batch testing. Before delivery the products to customers, we will do automatic Optical Inspection (AOI), X-Ray inspection, and burn-in testing, aim to provide high quality, zero defect products.

Production Flow

Solder Paste Printing>Mounting>AOI>Reflow Soldering>AOI Check>DIP>Wave Soldering>Funtion Test>PCBA

  • Solder Paste Printing

    The process of depositing solder paste on PCB to establish electrical connectionselectrical connections.

  • Mounting

    Using the PCB placement machine to put the required components on the PCB of the printed solder paste.

  • Reflow Soldering

    The solder paste is fused between the components and the PCB by reflow.

  • AOI Check

    Check the fusion between PCB and the circuit and test the function of the circuit.

  • DIP

    The PCBA plug-in of the DIP elements.

  • Wave Soldering

    Melting the angle of the DIP element above the PCB.

  • Function Test

    perform functional test of the circuit.

  • PCBA

    PCBA done.
