  What is   SMT automatic   optical inspection machine   The SMT automatic optical inspection machine (AOI) is an inspection device based on optical principles, mainly used for automatic inspection of surface defects of PCBA (printed circuit board assembly) during the SMT (surface mount technology) production process. The following is a detailed introduction to the SMT automatic optical inspection machine:   Definition and principle of SMT automatic optical inspection machine SMT automatic optical inspection machine, referred to as AOI, uses high-resolution cameras and advanced image processing algorithms to perform a full range of visual inspections on the surface of PCBAs. The camera automatically scans the PCB, collects images, and compares the tested solder joints with the qualified parameters in the database. After image processing, various defects on the PCBA can be quickly and accurately detected.   Main functions of SMT automatic optical inspection ...

Analysis of the problem of insufficient tin in SMT chip inductors As an indispensable component in modern electronic devices, the stability and reliability of chip inductors are crucial to the entire circuit system. However, in the actual production process, the soldering quality of chip inductors is often affected by many factors, among which the problem of insufficient tin is a more common one. This article will analyze the problem of insufficient tin in chip inductors in detail and explore its possible causes and solutions. Definition and impact of the problem of insufficient tin in chip inductors The problem of insufficient solder in SMD inductors refers to the soldering defects caused by insufficient solder during the soldering process of SMD inductors. This defect may cause a loose connection between the inductor pins and the PCB board, thus affecting the performance and stability of the inductor. Specifically, it manifests as insufficient solder joint strength, poor contact, poo...

  SMT machine Nozzles  can be classified into different types based on their structural form, suction pressure, and movement mode. Specifically, they can be divided into: straight insertion Nozzles, bending Nozzles, slider Nozzles, bending slider Nozzles, solenoid valve Nozzles, automatic adjustment Nozzles, etc.   Working Principles of SMT Nozzles The working principle of SMT Nozzles is to position and extract components through the vacuum suction inside the Nozzles, external pneumatic pressure, and the motion mechanism of the surface mount machine. When the vacuum suction reaches a certain value, the component is sucked onto the suction Nozzles, which is driven by the motion mechanism of the placement machine to move the component to the placement position, and then the vacuum suction is disconnected to complete the component placement.   Application of SMT Nozzles The  SMT ​ suction Nozzles is not only a key component for surface mount mac...

  Different types of feeders   have structural differences, but their working principles are basically the same, mainly including the following: 1. Component Identification and Positioning 2. Component Picking 3. Component Mounting 4. Feeder Reset and Preparation for Next Picking   Component Identification and Positioning The feeder identifies the type, size, and pin direction of components through internal sensors or cameras and transmits this information to the control system of the surface mount machine. The control system calculates the precise position of the components based on this information and commands the sticker head to pick them up.   Component Picking The sticker head is moved to the designated position of the feeder according to the instructions of the control system, and the components are picked up by vacuum suction or mechanical clamping. During the picking process, it is necessary to ensure that the pin direction and position of the components are...

  As a common component of   SMT machines , various problems may arise during operation, such as the inability to pick up, place, or install in the wrong position. So let's talk about the reasons and solutions for component extraction errors.   ● The suction coordinates (X, Y) for "suction data" are set incorrectly. In the case of tray components, the setting of "component starting position and spacing" in "component data" becomes the initial value for data extraction. Therefore, the "starting position, spacing, and number of components" of the "component data" should be entered correctly.   Solution: Reset the suction coordinates (X, Y).   ● The suction height (Z) for 'data suction' is set incorrectly. In this case, the suction nozzle cannot reach the component or cannot suck due to the reaction force generated by excessive pressure.   Solution: Reset the suction height (Z).   ● The nozzle selection is incorrect. Especially...
