Motor Controller PCB Assembly for BLDC and Industrial Motor Drives

Motor Controller PCB Assembly

Custom motor controller PCB assembly for BLDC, PMSM, servo and industrial motor drive applications. The PCBA is designed for motor control circuits that require high-current power stages, thermal management and reliable component assembly.

The manufacturing solution supports PCB fabrication, SMT and DIP assembly, component sourcing, inspection and functional testing for prototypes, small batches and mass production.

Motor Control Board Manufacturing

Motor controller boards combine power switching devices, gate drivers, current sensing circuits and control electronics. The PCB layout needs to handle high current while keeping heat away from sensitive control circuits.

The PCBA can be manufactured with heavy copper layers, high-Tg materials and thermal management features for demanding motor drive applications.

BLDC and PMSM Motor Controller

The motor control PCBA can be used for BLDC and PMSM motor systems, including applications requiring electronic commutation, current sensing and closed-loop motor control.

The board can integrate MOSFETs, IGBTs, gate driver ICs, shunt resistors, MCUs and connectors according to the motor and control system requirements.

Servo Drive PCBA

Servo drive boards require accurate current sensing, stable power switching and reliable control of the motor feedback system.

The PCBA can be customized for servo drive applications with power-stage components, control MCUs, current-sense circuits and communication interfaces selected according to the system design.

High-Current PCB Design

Motor controllers often carry substantial current through the power stage. The PCB can use copper weights from 1oz to 4oz, with heavier copper available for high-current sections.

Power traces, component pads and thermal areas can be designed around the required current, voltage and heat dissipation conditions.

Thermal Management

Power MOSFETs, IGBTs and other switching devices generate heat during motor operation. Proper PCB layout and thermal management are therefore important for reliable operation.

High-Tg FR4 and aluminum-base PCB options are available for different thermal and mechanical requirements. Thermal testing can also be included during production validation.

SMT and DIP Assembly

The motor controller PCBA supports both SMT and DIP assembly.

SMT production can handle MOSFETs, IGBTs, gate drivers, MCUs, current-sense components and other surface-mount devices. Through-hole assembly is available for connectors, power terminals and other large components.

Single-sided and double-sided assembly can be supported according to the PCB design.

Power Component Assembly

Motor control boards commonly use power semiconductor devices that require controlled soldering and reliable thermal connections.

The assembly process supports:

• MOSFET assembly

• IGBT assembly

• Gate driver ICs

• Shunt resistors

• MCU devices

• Power connectors

• Terminal blocks

• Current-sensing circuits

Inspection and testing can be selected according to the power-stage design.

PCB Materials and Construction

The motor controller boards support 2 to 16 PCB layers and copper weights from 1oz to 4oz.

Available PCB materials include FR4, High-Tg FR4 and aluminum-base boards. The material can be selected according to the electrical, thermal and mechanical requirements of the motor control system.

Inspection and Testing

Production inspection can include SPI, AOI, X-Ray and flying probe testing.

For motor control boards, ICT and functional testing can be used to verify control circuits and power-stage operation. Thermal testing and burn-in testing are also available for projects requiring additional reliability verification.

Conformal Coating and Potting

Motor controllers used in dusty, humid or vibrating environments may require additional protection.

Conformal coating and potting are available as optional processes to protect the assembled PCB from moisture, dust and environmental exposure.

OEM and ODM Motor Control PCBA

The motor controller board can be customized according to customer schematics, PCB files, Gerber files or functional requirements.

OEM and ODM services can include PCB design support, DFM review, PCB fabrication, component sourcing, SMT and DIP assembly, functional testing and production.

Prototype quantities can be produced for initial testing before moving to small-batch or mass production.
