3. Key Technical Parameters
3.1 Base Material and Board Thickness
- วัสดุฐาน: FR-4 (glass fiber reinforced epoxy copper-clad laminate)
- ความหนาของบอร์ด: 1.0มม
FR-4 is the most widely used rigid substrate in the PCB industry. Per IPC-4101, FR-4 offers excellent electrical insulation, ความแข็งแรงเชิงกล, และความต้านทานความร้อน. Standard FR-4 has a glass transition temperature (ทีจี) of 130–140°C. Per IPC-6012, the tolerance range for 1.0mm board thickness is ±0.1mm.
3.2 Layer Count and Dimensions
- จำนวนเลเยอร์: 2 ชั้น (บอร์ดสองด้าน)
- ขนาด: 86.37 × 72.6 มม
The 2-layer structure effectively controls manufacturing cost while delivering solid electrical performance. This makes it the mainstream choice for wireless vacuum cleaner control boards. The compact 86.37 × 72.6mm dimensions are optimized for the limited space inside vacuum cleaners.
3.3 Trace Width/Spacing and Minimum Hole Size
- ขนาดรูขั้นต่ำ: 0.45มม
- Trace Width/Spacing: 0.45มม / 0.391มม
Per IPC-2221Cมาตรฐานทั่วไปเกี่ยวกับการออกแบบแผ่นพิมพ์, trace width and spacing design must consider electrical performance, current-carrying capacity, and manufacturing capability. The 0.45mm minimum hole size supports reliable soldering of conventional DIP components and through-hole parts.
For current-carrying capacity, the industry-standard formulaI = k·ΔT^0.44·A^0.725 (where A is the trace cross-sectional area) shows that with 1oz copper, a 0.45mm (ประมาณ. 18MIL) trace can carry about 1.8–2.0A. The wireless vacuum cleaner PCB uses this trace width for motor drive signals and control signals, ensuring long-term stable operation.
3.4 Copper Foil Thickness
- Copper Foil Thickness: 1/1 ออนซ์ (1 ounce on both outer layers)
1ฟอยล์ทองแดงออนซ์ (ประมาณ. 35μm) is the standard configuration for consumer electronics PCBs. It strikes an excellent balance between current-carrying capacity, การนำความร้อน, และค่าใช้จ่าย.
3.5 พื้นผิวเสร็จสิ้น
- พื้นผิวเสร็จสิ้น: HASL ไร้สารตะกั่ว (การปรับระดับการบัดกรีด้วยอากาศร้อน)
HASL is a mature and economical PCB surface finish. Lead-free HASL meets RoHS environmental requirements. ตามมาตรฐาน IPC, lead-free HASL typically has a tin layer thickness of 1–40μm, with conventional processes控制在 5–25μm. This finish offers excellent solderability (wettability) and a good storage life of up to 12 เดือน.
3.6 หน้ากากประสานและตำนาน
- สีหน้ากากประสาน: Green ink
- Legend Color: สีขาว
Green solder mask is the industry’s most popular choice. It provides excellent insulation protection and high contrast for Aoi (การตรวจสอบด้วยแสงอัตโนมัติ). White legends are clear and easy to read, facilitating component placement and future maintenance.
4. แนวทางการออกแบบ: Following IPC-2221C Standards
A well-designed wireless vacuum cleaner PCB must follow these core principles (per IPC-2221C):
4.1 Electrical Performance Design
- Power Trace Width: Calculate using the formula I = k·ΔT^0.44·A^0.725 to ensure temperature rise stays below 10°C at maximum operating current.
- ความสมบูรณ์ของสัญญาณ: Use 0.45mm trace width for control signals to guarantee complete transmission of PWM speed control signals and sensor signals.
- Grounding Design: Use single-point grounding or split grounding strategies to prevent power loop interference with the control loop.
4.2 Thermal Management Design
Wireless vacuum cleaners generate significant heat from MOSFETs during operation. ที่ การออกแบบ PCB must address this by:
- Placing thermal via arrays under power devices.
- Widening high-current traces or adding exposed copper for better heat dissipation.
- Using 1.0mm board thickness to balance thermal conductivity and mechanical strength.
4.3 Mechanical Structure Design
ที่ 86.37 × 72.6mm dimensions must precisely match the vacuum cleaner housing. Mounting hole positions and connector locations must meet structural design requirements. The 0.45mm minimum hole size supports through-hole soldering for various DIP components and connectors.
5. หลักการทำงาน
The wireless vacuum cleaner PCB operates through the following core processes:
① Power Input and Management: The lithium battery pack (typically 21.6V or 25.2V) passes through the power management circuit on the PCB. This provides stable voltages to the main control chip and driver circuits.
② Main Control Chip Computation: The MCU (microcontroller) on the PCB receives button commands. It calculates and outputs three-phase drive signals using FOC (Field-Oriented Control) or square-wave control algorithms.
③ Motor Drive: The drive signals are amplified by MOSFET power devices. These signals then drive the brushless DC motor (BLDC) to rotate at high speed, generating the airflow needed for suction.
④ Feedback and Protection: The PCB continuously monitors motor current, battery voltage, อุณหภูมิ, and other parameters. When it detects abnormal conditions such as overcurrent, overtemperature, undervoltage, or rotor lock, it immediately executes protection actions.
