The feeder of SMT (Surface Mount Technology) refers to equipment used for surface mounting of electronic components, also known as placement machine or asm smt placement machine. The main function of Feeder is to accurately mount electronic components on the printed circuit board (PCB) to complete the circuit board assembly work.
Common chip components used in SMT include resistors, capacitors, integrated circuits, diodes, transistors, etc. These components are typically supplied in tape and placed via feeders or other automated placement equipment.
The general steps for mounting using smt Feeder are as follows:
Preparation: Confirm the components and PCB to be mounted and prepare them. Components are usually supplied in the form of tape and reel, while PCB requires pre-processing, such as tinning, etc.
Set up the feeder: According to the placement requirements, adjust the parameters of the feeder, such as device speed, size and position of the nozzle, etc. These parameters are adjusted based on component and PCB size, shape, and assembly requirements.
Calibration: Calibrate the feeder to ensure the accuracy of various parameters. This includes the positioning of the nozzle, the accuracy of the electric unit and the calibration of the control system.
Placement operation: Place the component to be placed in the feeder of the feeder and start the feeder. Feeder will automatically identify the location of the component and use the suction nozzle to pick up the component and then accurately place it at the predetermined location on the PCB.
Soldering: Once the component is mounted on the PCB, a soldering process may be required to ensure the electrical connection between the component and the PCB. This can be done with traditional wave soldering or surface mount techniques such as hot air ovens or reflow ovens.
Inspection and quality control: After SMT placement, quality inspection is usually required to ensure welding quality and component installation accuracy. This can include methods such as visual inspection, X-ray inspection, automated optical inspection and functional testing.
Please note that the exact method of using asm smt Feeder may vary depending on the device model, brand and manufacturer. Therefore, before using Feeder, be sure to refer to the equipment's operation manual and follow the manufacturer's instructions for SMT patch operations.
