When discussing the electronics manufacturing industry, one must first mention electronic components . Electronic components generally refer to electronic devices with specific functions . Common electronic components include resistors, capacitors , inductors , diodes , transistors, and integrated circuits composed of these components . Electronic components are the basic materials for manufacturing and producing electronic products .
Since the first iPhone was launched in 2007 , driven by both user demand and technological innovation , smart terminals have seen a rapid proliferation of new functions and rapid development . Achieving more functionality within limited space has become inevitable , leading to a continuous demand for miniaturized components . The advent of smart wearable devices, exemplified by Google Glass in 2012 , further pushed the miniaturization requirements for components in terms of size , weight , power consumption , and performance to new heights . The realization of these functions all requires the support of miniaturized components. With the application of 64-bit processors in mobile phones and the development of wearable devices , even higher demands will inevitably be placed on the miniaturization of components .
Miniaturization of electronic components is not limited to the components themselves , but also allows for further reduction in the size of the integrated circuits housing them . For example , TDK 's multilayer ceramic chip capacitors are only 1/100th the size of previous products , enabling high-density circuit integration. This trend will have two impacts on the electronics manufacturing industry :
Electronic components are smaller , thinner , and more easily damaged . Under the premise of ensuring yield and overall utilization rate, this makes it more difficult to transfer between processing steps and between steps . For example, some end actuators such as clamping , suction , pushing , and pressing are also developing towards smaller size , lighter weight , simpler structure , and higher integration .
The circuitry is denser, making alignment, surface mounting, insertion, dispensing, and soldering more challenging. During production, the linear displacement of each processing unit is very small, often less than 1mm between adjacent pin solder joints. In motion control programs, the motors operate in a state of frequent starts and stops. This poses a severe challenge to motor motion control. Even with the relatively mature multi-station, multi-batch processing technology, problems such as component misalignment and pin floating still occur.
For the reasons mentioned above , miniaturized motors are widely used in the electronics manufacturing industry due to their inherent advantages .
Firstly , its small size allows for a more compact mechanical structure and a higher degree of equipment integration .
Secondly, it is lightweight and has low inertia . Inertia is the magnitude of an object's motion, directly proportional to its mass, and is an important indicator of a motor. Generally, the lower the inertia, the faster the motor starts, accelerates, and stops , and the easier it is to control its motion.
Using miniature motors directly reduces the size and weight of the processing unit in electronic manufacturing equipment, further improving the overall processing performance of the machine.
Currently , servo motors and stepper motors are the most frequently used in general-purpose motion control products. In addition, there are some very expensive voice coil motors and linear motors . The most common servo motor frame sizes are 40 , 60 , and 80. From a size perspective , only some end effectors with low space requirements can use 40 - frame servo motors , such as dicing or CCD inspection equipment . However, for compact, highly integrated devices, such as wafer sorting and placement mechanisms, more miniature drive motors are needed. The available options are stepper motors with frame sizes of 28 (NEMA11) , 20 (NEMA8) , and 14 (NEMA6) .
While conventional stepper motors may not match the acceleration performance of servo motors in a single unit, they offer a wide range of sizes and specifications, and do not exhibit jitter during start-stop operations. Furthermore, they do not require gain tuning based on load changes during movement. These advantages benefit equipment manufacturers in design and selection, simplifying motion control programming instructions and facilitating on-site installation and commissioning. When equipped with high-resolution encoders and closed-loop control technology (current loop, position loop, speed loop), they not only retain the advantages of stepper motors—no dynamic tuning required and no jitter during start-up—but also maintain the characteristics of fast response and high overload capacity.
MOONS is a world-renowned comprehensive manufacturer in the field of motion control. With a rich and complete product portfolio, we aim to fully leverage our product innovation and diversification to provide customers with a variety of drive solutions tailored to their individual needs through perfect design. For example, in 2015, MOONS launched the TSM11 integrated stepper servo motor, a culmination of its technological expertise in 28 - frame products .
The TSM11 series integrates a control motor , a 16-bit incremental encoder , and a dedicated programmable driver within a limited space of 28mm . Operating at 15-30VDC , it features 4 digital inputs and 2 digital outputs. The heaviest model in the TSM11 series weighs only 218g , with a maximum output torque of 125mN.m . Designed for compact spaces , the integrated stepper servo motors of the TSM 11 series are widely used in specialized electronic manufacturing equipment for dispensing , insertion , and surface mount technology (SMT) processes. For example, in SMT processes, they can be configured into various combinations of 4 to 12 mounting heads . The advantages of the TSM 11 are not only its lightweight and small size; due to the integrated dedicated programmable driver , the electrical control cabinet can save considerable space for driver installation , simplifying overall wiring.
In 2020 , Mingzhi launched its new generation 20 - frame NEMA8 series hollow shaft step motor , further advancing the miniaturization of dispensing and placement mechanisms. The NEMA 8 series features a more compact body size, especially its innovative hollow shaft design that allows the air path to pass through the center of the motor. This design makes fixing the air hose easier, eliminating additional fixing components and further simplifying the mechanism for a more compact design. It also reduces accidents caused by air hose swaying during high-speed operation. The NEMA 8 series is compatible with vacuum chucks from many well-known pneumatic component manufacturers , such as SMC 's ZP3 series .
