1. 製品の概要: What Is a Wireless Vacuum Cleaner PCB?
A wireless vacuum cleaner PCB (プリント基板) is the core electronic component responsible for motor drive control, power management, user interaction, and safety protection inside a cordless vacuum cleaner. In simple terms, it serves as the “brain” and “nerve center” of the device. It receives button commands, controls brushless motor speed, manages battery charging and discharging, monitors operating status, and implements multiple safety protections.
UGPCB introduces this Wireless Vacuum Cleaner PCB – a 2-layer rigid printed circuit board designed specifically for portable cleaning equipment. It uses FR-4 glass epoxy copper-clad laminate as the base material. The board thickness is 1.0mm, and the dimensions are 86.37 × 72.6mm. This compact size fits perfectly into the tight internal spaces of handheld and stick-style cordless vacuums.

3. 主要な技術的パラメータ
3.1 Base Material and Board Thickness
- 基本材料: FR-4 (glass fiber reinforced epoxy copper-clad laminate)
- 板厚: 1.0mm
FR-4 is the most widely used rigid substrate in the PCB industry. Per IPC-4101, FR-4 offers excellent electrical insulation, 機械的強度, そして耐熱性. Standard FR-4 has a glass transition temperature (TG) of 130–140°C. Per IPC-6012, the tolerance range for 1.0mm board thickness is ±0.1mm.
3.2 層数と寸法
- レイヤー数: 2 レイヤー (両面ボード)
- 寸法: 86.37 × 72.6 mm
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
- 最小穴サイズ: 0.45mm
- トレース幅/間隔: 0.45mm / 0.391mm
Per IPC-2221CGeneric Standard on Printed Board Design, 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 (約. 18ミル) 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 銅箔の厚さ
- 銅箔の厚さ: 1/1 オズ (1 ounce on both outer layers)
1oz copper foil (約. 35μm) is the standard configuration for consumer electronics PCBs. It strikes an excellent balance between current-carrying capacity, 熱伝導率, コスト.
3.5 表面仕上げ
- 表面仕上げ: 鉛フリーHASL (熱気はんだレベリング)
HASL is a mature and economical PCB surface finish. Lead-free HASL meets RoHS environmental requirements. IPC標準ごと, 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 月.
3.6 Solder Mask and Legend
- はんだマスク色: Green ink
- Legend Color: 白
Green solder mask is the industry’s most popular choice. It provides excellent insulation protection and high contrast for あおい (自動光学検査). White legends are clear and easy to read, facilitating component placement and future maintenance.
4. 設計ガイドライン: 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.
- 信号の完全性: 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. The プリント基板設計 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
The 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. 作業原則
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 (マイクロコントローラー) 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, 温度, and other parameters. When it detects abnormal conditions such as overcurrent, overtemperature, undervoltage, or rotor lock, it immediately executes protection actions.
