1. Présentation du produit: What Is a Wireless Vacuum Cleaner PCB?
A wireless vacuum cleaner PCB (Circuit imprimé) 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.
Per IPC-6012F Qualification et spécifications de performances pour les cartes imprimées rigides, this product falls under the rigid double-sided printed board (with plated-through holes) category. As a key part of UGPCB’s one-stop PCB solutions, this product meets IPC international standards from design through manufacturing and quality control.

3. Key Technical Parameters
3.1 Base Material and Board Thickness
- Matériau de base: FR-4 (glass fiber reinforced epoxy copper-clad laminate)
- Épaisseur du panneau: 1.0mm
FR-4 is the most widely used rigid substrate in the PCB industry. Per IPC-4101, FR-4 offers excellent electrical insulation, résistance mécanique, et résistance à la chaleur. 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 Layer Count and Dimensions
- Nombre de couches: 2 couches (tableau double face)
- Dimensions: 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
- Minimum Hole Size: 0.45mm
- Largeur de trace / espacement: 0.45mm / 0.391mm
Per IPC-2221CNorme générique sur la conception des cartes imprimées, 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 (environ. 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 Épaisseur de la feuille de cuivre
- Épaisseur de la feuille de cuivre: 1/1 once (1 ounce on both outer layers)
1feuille de cuivre d'une once (environ. 35µm) is the standard configuration for consumer electronics PCBs. It strikes an excellent balance between current-carrying capacity, conductivité thermique, et coûter.
3.5 Finition de surface
- Finition de surface: HASL sans plomb (Nivellement de la soudure à air chaud)
HASL is a mature and economical PCB surface finish. Lead-free HASL meets RoHS environmental requirements. Par normes 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 mois.
3.6 Masque de soudure et légende
- Couleur du masque de soudure: Green ink
- Legend Color: Blanc
Green solder mask is the industry’s most popular choice. It provides excellent insulation protection and high contrast for Zone d'intérêt (Inspection optique automatisée). White legends are clear and easy to read, facilitating component placement and future maintenance.
4. Directives de conception: 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.
- Intégrité du signal: 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 Conception de gestion thermique
Wireless vacuum cleaners generate significant heat from MOSFETs during operation. Le Conception de circuits imprimés 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
Le 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. Principe de fonctionnement
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 (microcontrôleur) 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, température, and other parameters. When it detects abnormal conditions such as overcurrent, overtemperature, undervoltage, or rotor lock, it immediately executes protection actions.
