Recently, a screening conveyor has been put into use in the SMT production lines of several electronic manufacturing enterprises. This equipment, with its features of precise sorting, continuous conveying and high degree of automation, has effectively solved the problem of automatic separation of OK boards and NG boards (qualified products and defective products) in the production lines, and has become an important tool for improving quality control efficiency and reducing manual intervention. What is a screening conveyor?The screening conveyor is a specialized peripheral equipment for the SMT surface mount production line. Its main function is to automatically screen and sort PCB circuit boards during the production process. It uses sensors or receives signals from upstream equipment (such as AOI, SPI) to automatically send qualified boards to the main water line and direct defective boards into separate channels or designated storage boxes, achieving real-time control of production line yield and automatic material diversion.This equipment adopts a classic gray-green color industrial design. The upper part is equipped with multiple layers of Magazine storage racks, which can accommodate multiple PCBs simultaneously; the middle part is a green anti-static conveyor belt, and the lower part is equipped with a storage cabinet. The overall structure is compact and easy to move.

What is a Parallel Transfer Machine? The parallel transfer machine is a type of peripheral auxiliary equipment for SMT. Its main function is to horizontally transfer PCB boards between two parallel or adjacent conveying tracks. It can smoothly and accurately transfer the circuit boards output from the previous process to another parallel production line, achieving horizontal connection, avoidance or diversion of the production lines, without the need for large-scale layout adjustments of the entire workshop.Compared with traditional long-distance conveying lines, the parallel transfer machine has a smaller footprint. It usually adopts a modular design and can be easily moved and connected to different equipment, making it particularly suitable for modern SMT workshops with limited space. Main features  Precise lateral transfer: Utilizing high-precision rails and positioning systems, it ensures the PCB is transferred smoothly without any shaking, with low positioning errors, and effectively protects the components on the board.Intelligent control: Equipped with an industrial touch screen, it supports manual, automatic and online modes, and can be connected to the MES system to achieve real-time data interaction.Compact structure: The entire machine adopts a white industrial painted body, with multiple storage cabinets set below for convenient storage of common tools and spare parts; the bottom is equipped with swivel wheels for easy movement, and ground feet cups are used for stability when fixed.Safe and reliable: Equipped with three-color warning lights, emergency stop buttons, and anti-static transfer mechanisms, it complies with the safety and static protection requirements of the electronic manufacturing industry.High compatibility: Supports various PCB size ranges, and can quickly adjust the track width to meet the production needs of different products. Core advantage The most significant feature of this parallel transfer machine lies in enhancing the flexibility of the production line. When two soldering lines or inspection lines are arranged in parallel, it can quickly achieve the lateral transfer of the board pieces, avoiding the problems of space waste and excessively long transportation distances caused by traditional U-shaped or L-shaped return circuits. At the same time, it can also be used as a buffer zone, temporarily storing parts when the production line cycle times of the preceding and subsequent equipment do not match, thereby improving the overall production line utilization rate.According to feedback from the user, after introducing the parallel transfer machine, the adjustment time for the production line layout has been significantly shortened, and the space utilization rate has improved significantly. It is particularly suitable for mixed production modes of small and medium-sized board cards in fields such as mobile phones, automotive electronics, and medical equipment. Typical application scenarios Transferring boards laterally between multiple parallel SMT production linesFlexible connection between AOI inspection equipment, surface mounters and reflow soldering furnacesSituations where the material flow needs to be changed in the line optimization and renovation projectIntelligent scheduling in the high-mix production environment The launch of this parallel transfer machine provides electronic manufacturing enterprises with a cost-effective and high-return solution for optimizing production lines. As the construction of intelligent factories progresses, the flexible application of similar SMT peripheral auxiliary equipment is becoming an important direction for enhancing manufacturing efficiency.

With the increasing penetration of Electric Vehicles (EVs), the requirements for consistency in PCB assembly for Electronic Control Units (ECUs) and advanced driver-assistance systems (ADAS) have reached unprecedented levels. In Thailand’s high-humidity production environments, traditional offline sampling models often fail to detect issues like solder paste oxidation or component shifting in real-time. This lag in detection leads to high rework costs and potential reliability risks in the final vehicle assembly. To maintain competitiveness, Thai EMS (Electronic Manufacturing Services) providers are shifting toward integrated, automated quality control. Core Technical Parameters of Online QC Conveyor Systems To achieve true zero-defect flow within SMT lines, intelligent conveyor systems like the KTD-108 introduce precise parameterized control. These metrics ensure that every PCB is verified before the irreversible reflow soldering process. 1. Mechanical Positioning and Transmission Precision High-precision placement is only possible with a stable transmission baseline. Transmission Deviation: Utilizing a double-speed chain structure, the PCB displacement deviation is strictly controlled within ≤0.1mm. Height Compatibility: The rail height supports an adjustable range of 900±20mm, ensuring seamless integration with standard SMT lines used across Thailand. Vibration Control: Variable frequency motor control ensures that components do not shift due to mechanical vibration during high-speed transport. 2. Integrated Inspection and Vision Capabilities Placement Precision Support: The system supports real-time vision alignment for components ranging from 0201 to QFP packages, with a placement accuracy deviation stable at ≤±0.02mm. Defect Detection Rate: By identifying missing parts, polarity reversals, and insufficient soldering online, the integrated detection unit achieves a comprehensive capture rate of ≥99.5%. Addressing Thailand Factory Pain Points: Strategies to Reduce Defect Rates Blocking Defect Downstream: From Post-Inspection to Real-time Interception In many Thai manufacturing facilities, Manual Visual Inspection (MVI) is still common but is limited by operator fatigue, leading to inconsistent quality. An Online QC Conveyor replaces the passive "wait and see" approach with active interception. The system performs logical verification the moment a placement is completed. If a parameter exceeds the pre-set tolerance, the equipment response time is ≤1 second, triggering immediate alerts via tri-color warning lights and screen pop-ups. This ensures that only 100% compliant PCBs move to the next stage, significantly reducing the "Scrap Rate" of the entire line. Enhancing Flexible Manufacturing for High-Mix Low-Volume Orders Thailand’s Tier-2 and Tier-3 suppliers often handle a diverse range of product models in smaller batches. The KTD-108 supports rapid changeover logic, where mechanical rail widths and inspection programs can be adjusted in ≤15 minutes. This flexibility minimizes downtime and utilizes MES (Manufacturing Execution System) integration to ensure that different batches maintain identical quality standards through data-driven process control. Sourcing Guide: Key Dimensions for Technical Selection For procurement managers and engineers in Thailand, technical selection should focus on industrial-grade durability and connectivity: Material Standards: Ensure structural components use 6061-T6 anodized aluminum or specialized coatings to resist corrosion in tropical climates. Protocol Standards: Systems must support the SMEMA interface to facilitate communication between the conveyor, mounter, and reflow oven. Digital Traceability: The ability to link inspection results to unique PCB barcodes is essential for meeting the IATF 16949 standards required by global automotive OEMs.
