Exclusive PCBA ODM solution for cordless vacuum cleaners! Long battery life and stable suction, quickly launch high-quality products.

　　A manufacturer developing a handheld cordless vacuum cleaner suffered a battery life of only 20 minutes due to unbalanced PCBA power management, leading to a surge in user complaints. Another manufacturer experienced unstable motor control in an upright vacuum cleaner, resulting in fluctuating suction power, and repeated adjustments during the testing phase, delaying launch. Another manufacturer sought to integrate dust detection and app integration, but due to the high technical barriers to entry for PCBAs, the in-house development cycle exceeded six months. The core competitiveness of cordless vacuum cleaners (battery life, suction power, and smart user experience) relies entirely on PCBA performance. Traditional in-house development models are prone to technical bottlenecks and mass production challenges. Our PCBA ODM solution for cordless vacuum cleaners addresses these pain points across the entire supply chain, from customized development to mass production delivery, allowing manufacturers to focus on product design and quickly meet market demand.

　　Traditional cordless vacuum cleaner PCBA development presents significant pain points: universal PCBAs are difficult to adapt to brushless motors (speed fluctuations of ±10%), making it difficult to balance suction power and noise. Power management modules lack compatibility and are unable to work with 18V, 21V, or 25V lithium batteries, resulting in varying battery life. Intelligent function integration is costly (for example, dust detection requires an additional module), and mass production yield is difficult to control (manual soldering yield ≤ 92%). A lack of targeted reliability testing can lead to short circuits in humid environments (such as kitchens). However, the dedicated ODM solution, through "customization + technical expertise + guaranteed mass production," allows PCBAs to be precisely tailored to the specific needs of cordless vacuum cleaners, shortening the R&D to mass production cycle by 50%.

　　Why is it the preferred choice for cordless vacuum cleaner manufacturers? Four core advantages of ODMs

　　1. Customized Power Management: Double the battery life, worry-free fast charging

　　Targeting the "long battery life + fast charging" requirements of cordless vacuum cleaners, a dedicated power management module (PMU) was developed:

　　Multi-voltage adaptability: Supports 18V/21V/25V lithium battery packs (2-6 strings), compatible with ternary lithium and lithium iron phosphate materials, and can customize battery life based on the manufacturer's product positioning (e.g., 30 minutes of strong suction/60 minutes of weak suction for handheld models, 45 minutes of strong suction/90 minutes of weak suction for upright models);

　　High-efficiency fast charging technology: Integrated with PD/QC fast charging protocols, compatible with 65W/80W fast charging chargers, it can charge to 80% in 30 minutes (compared to 60 minutes for standard PCBAs). It also features overcharge (voltage ≤ 2.5V/single cell) and overdischarge (voltage ≥ 3.6V/ Single-cell) and overcurrent (current ≤ 15A) protection prevent battery swelling or burning.

　　Low-power optimization: Standby power consumption is ≤ 80μA (common PCBA ≥ 200μA), and power loss in the off state is ≤ 2% per month, resolving the user pain point of "long-term battery drain." Battery cycle life is increased to 1200 cycles (compared to the industry average of 800 cycles).

　　2. Brushless Motor Precision Drive: Stable Suction, Low Noise

　　For the brushless motor control at the heart of cordless vacuum cleaners, ODM Solutions has deeply delved into drive technology:

　　High-Precision Speed Control: Utilizing a 32-bit MCU (such as the STM32G4 series) and a Field-of-Call (FOC) vector control algorithm, the motor speed adjustment range is 5,000-30,000 rpm, with a fluctuation of ≤±3%. This ensures stable suction (e.g., no attenuation in the 12kPa high suction setting) while reducing motor noise (≤65dB, compared to ≥72dB in normal operation), making it suitable for quiet environments like bedrooms and nurseries.

　　Load Adaptation: An integrated current sampling module automatically adjusts motor power based on dust concentration (e.g., when vacuuming carpets, the current increases from 8A to 12A, enhancing suction power; when vacuuming hard floors, the current drops to 5A, saving energy and extending battery life), eliminating the hassle of manual gear shifting.

　　Fault Self-Protection: When the motor stalls (e.g., when sucking in a coin), the PCBA automatically triggers current limiting protection (current ≤18A). The vacuum cleaner shuts down and issues an alarm after a few seconds, preventing motor burnout and reducing after-sales repair rates by 60%.

　　3. Intelligent Function Integration: Achieve a High-Quality Experience at a Low Cost

　　On-demand integration of mainstream cordless vacuum cleaner smart functions without the need for additional development:

　　Dust Full Detection: The PCBA includes a reserved infrared sensor/pressure sensor interface for direct connection to the dust cup detection module. When the dust cup is clogged, an LED light or app prompts the user to clean it, preventing a drop in suction power (detection accuracy ≤ 0.1g/cm³);

　　Multi-Level Control: Supports physical button/touch/app control, with four customizable suction modes: strong suction, weak suction, energy saving, and MAX. Frequently used settings are memorized and automatically switched the next time the vacuum cleaner is turned on;

　　Bluetooth/Wi-Fi Linkage: Integrated with low-power Bluetooth 5.0 (such as the nRF52832) or a Wi-Fi module (such as the ESP32-C3), the vacuum cleaner enables app-based battery status monitoring, fault alarms (such as motor failure and battery aging), and OTA updates, increasing product premium potential.

　　4. Mass Production Delivery Guarantee: High Yield, Short Cycle Time

　　The ODM model provides a full-chain service chain from R&D to testing to mass production, solving manufacturers' mass production challenges:

　　Fast R&D: Based on a mature technology platform, customized development cycles are as short as 30-45 days (90-120 days for in-house development). PCBA samples (10-50 sets) are provided for manufacturers to test the entire device, supporting functional adjustments and iterations.

　　Automated Mass Production: Utilizing Panasonic's NPM-D3 SMT production line (positioning accuracy ±0.01mm), coupled with AOI automated optical inspection (AOI), ICT in-line testing, and FCT functional testing, the mass production yield remains stable at over 99.5%, with a daily production capacity of 5,000 PCBAs.

　　Reliability Testing: Specific tests are performed for cordless vacuum cleaner usage scenarios:

　　Temperature and Humidity Cycle Testing (-20°C to 60°C, 95% RH, 500°C) 100 cycles), suitable for high-temperature kitchens and humid bathroom environments;

　　Drop tested (1.2 meters onto concrete floor, no PCBA components detached), suitable for accidental drops during handheld use;

　　Electromagnetic compatibility tested (EMC radiation ≤ 30dBμV/m) to prevent interference with other household appliances.

　　Scenario Tests: Compatibility with Different Types of Cordless Vacuum Cleaners

　　Handheld Cordless Vacuum Cleaner: Customized miniaturized PCBA (25% smaller, ≤1.5mm thick) to fit the lightweight design. The power management module supports a 21V 4Ah lithium battery, boasting 35 minutes of powerful suction and a 40-minute fast charge. The app's battery level check function has a user satisfaction rating of 92%.

　　Upright Cordless Vacuum Cleaner: Developed a high-power motor-driven PCBA that supports a 25V 6Ah lithium battery, offering a maximum suction power of 18kPa. The load-adaptive function keeps the noise level stable at 62dB when vacuuming carpets and floors. The mass production yield is 99.8%, and the after-sales service repair rate has dropped from 15% to 1.2%.

　　Car Cordless Vacuum Cleaner: Customized 12V car charger + lithium battery dual-powered PCBA, with standby power consumption ≤50μA and built-in overvoltage protection (compatible with 12V-14.5V in-vehicle charging). Voltage fluctuations) and remained functional after drop testing. The manufacturer went from R&D to mass production in just 40 days, quickly capturing the automotive accessories market.

　　The mite-removing cordless vacuum cleaner integrates high-frequency vibration motor control (12,000 vibrations/minute) and UV sterilization control. The PCBA simultaneously adjusts suction power and vibration frequency, increasing the mite removal rate to 99.2%. It has passed EMC testing, eliminating concerns about radiation interference.
