UGPCB offers this professional-grade hair curler printed circuit board with high-standard industrial design and manufacturing processes. It delivers a stable and reliable electronic control solution for various hair styling equipment.

This hair curler PCBA core board measures 76.82 × 13.6 mm. It uses FR-4 rigid glass-epoxy laminate material. FR-4 is an internationally recognized flame-retardant epoxy glass cloth laminate. Its flame retardancy meets UL 94 V-0 normes. This requires the material to self-extinguish within 10 seconds during vertical burn testing. It must also produce no flaming drips that ignite cotton. This provides fundamental safety assurance for hair curlers operating under high-power heating conditions. The material has a glass transition temperature (Tg) of 130–140°C. This ensures effective resistance to thermal stress during hair curler operation.

Line width and spacing are0.3 mm et 0.41 mm respectivement. Surface treatment usesOSP (Conservateurs de soudabilité organique) antioxydant finition. Solder mask isnoir avecblanc silkscreen characters. This delivers a clean and professional appearance.

This hair curler circuit board is now available on the Site officiel de l'UGPCB. It suits intelligent hair curlers, straightening-curling combo devices, and other hair styling equipment.

Définition du produit: What Is a Hair Curler PCB?

UN hair curler PCB (Circuit imprimé) is the core electronic component inside a hair curler. It provides electrical connections, transmission de signaux, and functional control. The board connects power input, main control chips, temperature sensors, heating elements, and display modules through conductive traces. Ces composants form a complete functional system.

From a technical perspective, this is a consumer-grade rigid double-sided printed circuit board. It falls under the rigid printed board category defined in IPC-6012. Under IPC product class classification, ce hair curler PCB belongs to Classe 2 (Produits électroniques à service dédié). This classification applies to consumer devices requiring continuous operation and extended service life.

Cehair curler circuit board integrates four core functional modules through precision circuit design:

Power input circuit: Converts external power (AC 110V/220V or DC battery) to the operating voltage required by the device.
Power management circuit: Regulates, filtres, and distributes power to ensure stable operation of each module.
Main control circuit: Includes the main control chip, charging detection circuit, and battery temperature detection circuit.
Heating wire control circuit: Precisely controls heating element power on/off to achieve temperature regulation.

In terms of product form, cehair curler PCB is supplied as a bare board (without PCBA assembly). Customers can perform their own component mounting and functional customization based on specific product requirements.

Faits saillants de conception: Precision Calculation and Engineering Expertise

Compact Dimensions with High-Density Routing

Cehair curler PCB board measures just76.82 × 13.6 mm. This long and narrow space must accommodate complete power management, main control, and heating control circuits. Design engineers face significant high-density routing challenges. The precision parameters—minimum aperture0.32 mm, line width/spacing0.3/0.41 mm—enable reliable trace routing within the limited board area.

ParCIB-2221 (Norme générique sur la conception des cartes imprimées), designers must consider electrical clearance (creepage distance), contrôle d'impédance, et gestion thermique. Le 0.32 mm minimum aperture ensures reliable plated-through holes while leaving sufficient space for high-density routing.

Conception de gestion thermique

Hair curlers generate heating element temperatures ranging from 80°C to 200°C during operation. Le PCB sits close to the heat source as the control board. It must demonstrate excellent heat resistance. Le FR-4 material choice (Tg 130–140°C) et 1.0 mm board thickness maintain mechanical strength while optimizing thermal dissipation paths.

Electrical Performance Design

Le1/1 once copper foil thickness (environ 35 μm per layer) ensures sufficient current-carrying capacity. Per IPC-2221 current-carrying calculation standards, 1 OZ copper can carry approximately 1–1.5 A per millimeter of trace width at a 10°C temperature rise. Le 0.3 mm trace width combined with 1 OZ copper thickness adequately meets the current requirements of hair curler heating control circuits.

Sélection de finition de surface

OSP (Conservateurs de soudabilité organique) antioxidant surface treatment is selected with an OSP film thickness of0.2–0.5 μm. This choice is based on several key considerations:

Avantage de coût: OSP offers lower cost, suitable for high-volume consumer electronics production.
Excellente planéité de la surface: OSP-treated pads provide a very flat surface, ideal for SMT assembly.
Respectueux de l'environnement: OSP contains no lead or other hazardous substances, meeting RoHS requirements.
Bonne soudabilité: The OSP protective film is quickly removed by flux at soldering temperatures, ensuring quality solder joints.

It is worth noting that OSP-finished PCBs should be assembleddans 8 à 24 heures of unpacking to prevent copper surface oxidation. Customers should coordinate their production schedules accordingly.

Principe de fonctionnement: From Power Input to Precision Temperature Control

System Workflow

The overall working principle of thishair curler control circuit follows five steps:

Étape 1: Power Input and Conversion. External power (AC 110V/220V or built-in lithium battery) enters the PCB through the power input circuit. The power management circuit rectifies, filtres, and regulates the voltage. It then supplies the required operating voltage to each module.

Étape 2: Temperature Setting and Signal Acquisition. Users set the desired temperature (80–200°C adjustable) via buttons or knobs. Entre-temps, the on-boardNTC thermistor temperature detection circuit monitors the heating element temperature in real time. It converts temperature signals into electrical signals and feeds them back to the main control chip.

Étape 3: Main Control Chip Computation and Decision. The MCU (Microcontroller Unit) receives both the set temperature value and the real-time temperature feedback. It performs calculations using a PID (Proportional-Integral-Derivative) control algorithm or a simplified temperature control logic. It determines the deviation between current and target temperatures.

Étape 4: PWM Drive Output. The MCU outputs PWM (Pulse Width Modulation) signals based on computation results. These signals control the heating element power through the drive circuit. When temperature falls below the set value, heating power increases. When temperature approaches or reaches the set value, heating power decreases or shuts off.

Étape 5: Safety Protection Mechanism. The system continuously monitors battery temperature, heating wire temperature, and circuit current. When anomalies are detected—such as over-temperature, over-current, or short circuits—thefault detection and auto-protection circuit immediately cuts off power to ensure user safety.

Bimetal Thermostat Principle (Reference for Traditional Solutions)

Some hair curler products use bimetal strips as temperature control elements. The principle works as follows: as temperature rises, heat transfers to the bimetal disc. Because the two metals have different coefficients of thermal expansion, the disc deforms and bends. At a predetermined temperature, it rapidly actuates. Through a mechanical mechanism, it opens or closes contacts, thereby switching the circuit on or off. Modern intelligent hair curlers typically use MCU-plus-temperature-sensor electronic temperature control solutions. These offer significantly higher temperature control accuracy.
