Product Introduction
Announcement Editor
This equipment adopts an integrated production line (printing, assembly, inspection) and uses a dual-track conveyor belt design. It can perform component assembly on one track while replacing the substrate on the other track [1] [11].
This equipment allows customers to freely choose the assembly line and achieve the "Plug & Play" function through the configuration of each process mounting head [10] [12].
This equipment realizes the overall management of the production line, workshop and factory through system software, inheriting the same platform of the CM series. Its operation interface supports mounting of components ranging from 0402 (imperial 01005) to 100×90mm [10] [12].
Working principle
Announcement Editor
The working principle of the Panasonic NPM surface mount machine mainly consists of the following automated steps: Firstly, a signal for the board is sent, and the substrate is conveyed to the correct position; then, the mounting table (table) rises to the designated position, and the positioning camera reads the reference point of the substrate; subsequently, the working head moves to the feeder and uses the vacuum principle to pick up the component; then, the working head adsorbs the component and moves it to the component camera to determine whether the shape data of the component meets the set value; for components that meet the set value, the working head performs the mounting according to the programmed coordinates; for those that do not meet the set value, the component is thrown into the waste box; this cycle of actions completes the predetermined mounting, after which the mounting table descends, receives the outboard signal, and sends out the substrate.

Announcement Editor
The Panasonic NPM series surface mounters mainly include models such as NPM-D2 and NPM-D3. The subsequent upgraded models like NPM-D3A have improved speed and system performance [9].
The model NPM-D2 is named NPM-D2. Its substrate size in the dual-track system is L50mm×W50mm to L510mm×W300mm, and in the single-track system it is L50mm×W50mm to L510mm×W590mm. The substrate replacement time in the dual-track system is 0 seconds (when the cycle time is below 4.5 seconds, it cannot be 0 seconds), and in the single-track system it is 3.9 seconds. The power requirement is three-phase AC 200, 220, 380, 400, 420, 480V, 2.5kVA. The equipment size is W835mm×D2652mm×H1444mm, and the weight is 1620kg. The types of the mounting heads include 16-nozzle, 12-nozzle, 8-nozzle and 2-nozzle mounting heads. The fastest mounting speed of the 16-nozzle mounting head is 70,000 cph (0.051 seconds per chip), with a mounting accuracy of ±40μm per chip, corresponding to component sizes from 0402 to L6×W6×T3.

The operating system of NPM-D3A has intelligent features, with an emphasis on user experience in the operation interface design, enhanced data management and analysis functions, and equipment maintenance design considering convenience. NPM-D3A is often used in large and complex production lines, with a relatively higher initial investment [9].
Model Comparison
Announcement Editor
Among the Panasonic NPM series pick-and-place machines, NPM-D3 and NPM-D3A are two popular models. NPM-D3 is a high-performance SMT pick-and-place machine designed to meet high production capacity and high precision requirements, while NPM-D3A is an upgraded version based on D3, incorporating the latest technological advancements to enhance production efficiency and stability. [9]
In terms of pick-and-place speed, NPM-D3 can reach 74,000 pieces per hour, and NPM-D3A can increase to 77,000 pieces per hour. The installation head of NPM-D3A adopts more advanced technology, featuring higher precision and flexibility; NPM-D3 uses a more traditional control system, while NPM-D3A is equipped with a more intelligent operating system that can monitor the production status in real time. [9]
In terms of the operation interface, NPM-D3A is more user-friendly and easier to operate, while the operation interface of NPM-D3 is more complex and requires a longer training period. The operation interface of NPM-D3A provides stronger support for data management and analysis functions. In terms of equipment maintenance, NPM-D3A is more user-friendly, making it easier for maintenance personnel to access internal components, while NPM-D3 is slightly lacking in this aspect. [9]
Panasonic's after-sales service enjoys a good reputation, and NPM-D3A users usually receive a faster update response. NPM-D3 is more suitable for small and medium-sized production lines, while NPM-D3A is more suitable for large and complex production line applications. NPM-D3A has a higher initial investment, but its efficient production capacity and lower maintenance costs can be recovered in a shorter period of time; NPM-D3 has a lower purchase cost. [9]

Operation process
Announcement Editor
When starting up the machine, check the items inside and on the top of the machine and ensure the air pressure is between 0.5 and 0.8 Mpa. Connect the external power supply of the machine, turn on the main power switch, and wait for about 3 minutes to enter the operator mode. Enter the engineering mode and input the password, click the machine adjustment, hold the "ENABLING" key while pressing the "Reset" key to reset the origin and zero position. After resetting, click the operation panel to enter the main operation interface. If the machine has been stopped for more than 24 hours, set the production action to be shielded in the main menu setting interface and idle for 10 minutes to warm up [8].
During operation, wear an electrostatic wristband and confirm that the machine is running normally and the suction nozzle model and position are correct. The program is transmitted from the main control computer to the soldering machine and loaded in the file preparation interface. Loading materials follows the Feeder table. After self-check by the operator, notify the inspector to check the materials, and verify the physical number, computer material number and Feeder table material number. Pay attention to the consistency of the polarity of the components and the inspection of the packaged components one by one. For material replacement, follow the screen prompts and operate strictly in accordance with the material replacement operation guide. Adjust the connection table to the AUTO state and wait for the substrate to enter production. The operator performs the soldering according to the operation guide, and after soldering, the substrate enters the next process through the connection table. In case of BOC errors, VCS recognition errors, laser vision errors, tray errors, component suction errors, severe throwing material (the component loss rate is generally 3‰) or insufficient air pressure, find a technician to solve the problem. At the same time, pay attention to the material situation and prepare the materials that are about to run out in advance, and restore the supply status after replacing the materials [8].
When shutting down the machine, press "Stop" to stop and exit the production program. Enter the machine adjustment mode, hold the "ENABLING" key while pressing the "Start" key to reset the origin and zero position. After the operation is completed, directly turn off the main power switch of the machine [8].
During operation, check whether the program name and version are consistent with the product. In case of an emergency, press the emergency stop button and ask the engineering personnel to solve the problem. During machine operation, it is strictly prohibited to extend any part of the body or items into the front and rear covers of the machine. For internal machine operations such as material replacement, select the servo lock key to lock before operating, and do not allow two people to operate the same machine at the same time. When pushing and pulling the module X/Y axis, hold the hand brake, gently pull and push to avoid rough operation [8].
