This video offers a detailed look into the manufacturing process of Beelink mini PCs, from raw materials to finished products. It meticulously documents each stage, beginning with the fabrication of the metal chassis through stamping, precision milling, cleaning, and surface treatments like sandblasting and anodizing. The production then moves to the assembly of printed circuit boards (PCBs) using both automated Surface Mount Technology (SMT) for component placement and manual Through-Hole (DIP) insertion, followed by various board-level tests and preparations. The final stages involve the comprehensive assembly of all internal components, including cooling systems, memory, and storage, culminating in extensive functional, stability, and cosmetic quality control testing to ensure product reliability before shipment.
Beelink Mini PC Manufacturing Process: A Comprehensive Production Tour
0:00 Introduction to Beelink: Beelink, established in 2011, specializes in the research, development, and production of mini PCs, used widely in office, entertainment, and cloud computing. The video details their manufacturing process.
0:54 Chassis Manufacturing (Stamping & Milling): The process begins in the Stamping Workshop, where metal is lubricated and aluminum blanks are precision-stamped to form the chassis. The Milling Workshop then refines these parts by trimming edges, polishing surfaces with coolant lubrication, and applying protective films, followed by surface grinding treatment.
3:10 Chassis Cleaning & Surface Treatment: Chassis parts are mounted on racks for high-temperature cleaning and then dried in industrial ovens. They undergo sandblasting for texture before being anodized, including color treatment, to enhance durability and aesthetics.
6:57 Laser Engraving & PCB Assembly (SMT): The Beelink logo is laser-engraved onto the chassis. The SMT Assembly Line follows, featuring automated solder paste printing, high-speed component placement, and reflow soldering for the PCBs.
9:52 DIP Component Insertion & Soldering: Manual Through-Hole (DIP) components, such as I/O ports, are installed. These parts are then secured using wave soldering, followed by cleaning of pins and installation of the CMOS battery. Any necessary solder joint repairs are also performed.
11:18 Motherboard Preparation & Initial Testing: High-temperature tape is removed, and various labels are applied for RAM slots, storage bays, and Wi-Fi antenna ports. Boards undergo inductor impedance tests and MAC address programming.
12:33 Full Interface Functionality Test & CPU Preparation: Each motherboard undergoes a comprehensive test to ensure all interfaces are functional. CPU thermal compound is applied and UV cured, and the CPU surface is cleaned, with all manufacturing data logged into the MES system.
13:45 Final Assembly: The Final Assembly Workshop integrates components like motherboard batteries (after voltage check), CPU heatsinks, thermal pads for capacitors, and EMI shielding tape. QR codes are labeled and scanned for tracking.
15:13 Cooling System & Module Installation: CPU coolers and cooling fans are assembled and installed, followed by an inspection of the entire cooling system. Rear I/O panels, front panel modules, and Wi-Fi antenna modules are also installed.
17:07 RAM & SSD Installation: RAM modules and both M.2 and SATA SSDs are installed into the units, with SSD heatsinks mounted where applicable.
17:35 System Functional & Stability Tests: A full system functional test is performed. Dust filters are installed, and the bottom cover is assembled after internal components are securely checked.
18:49 Quality Assurance & Pre-Shipment: Products undergo a rigorous burn-in and stability test, followed by SN barcode verification and the installation of decorative screw caps. A final QA station scan, pre-shipment retest, and AQL (Acceptance Quality Limit) cosmetic inspection are conducted to ensure product quality.
