Key Features of the Inverter PCB Assembly

Designed for DC-to-AC Power Conversion Applications

This PCB assembly can be manufactured for inverter systems that convert low-voltage DC power, such as 12V or 24V battery input, into AC power for downstream electrical loads.

Typical designs can be used in solar, battery-powered and backup power systems.

Custom PCB and PCBA Manufacturing

AVPCB supports customized inverter PCB projects based on customer Gerber files, BOM and assembly documentation.

Available services include:

• PCB fabrication
• Electronic component sourcing
• SMT assembly
• DIP / through-hole assembly
• Mixed-technology assembly
• PCB copy / board duplication
• Functional testing
• Prototype and batch production

Key Manufacturing Considerations for Inverter PCBs

Current-Carrying Capacity

Inverter circuits can contain power paths carrying significantly higher current than ordinary control electronics.

Trace width, copper thickness and PCB layout should therefore be selected according to:

• Operating current
• Peak current
• Copper weight
• Temperature rise
• PCB size
• Cooling conditions

For higher-current inverter projects, heavier copper specifications may need to be evaluated rather than automatically using a standard 1 oz structure.

Thermal Management

Power MOSFETs, IGBTs, diodes and other switching devices can generate significant heat during inverter operation.

PCB and PCBA design may therefore need to consider:

• Wider copper areas
• Thermal vias
• Heat-spreading copper
• Component spacing
• Heat sink mounting
• Thermal interface requirements

Power Components and Through-Hole Assembly

Unlike many compact consumer PCBAs, inverter boards commonly contain larger power components such as:

• MOSFETs
• IGBTs
• Power diodes
• Transformers
• Inductors
• Electrolytic capacitors
• Relays
• High-current connectors

As a result, inverter PCB assembly may combine SMT and through-hole technologies.

AVPCB currently provides both SMD and DIP assembly as part of its one-stop manufacturing service.

PCB Assembly for Solar Inverter Applications

SMT Assembly

Surface-mount components such as resistors, capacitors, ICs and control devices can be placed using automated SMT equipment.

AVPCB states that it operates five high-speed SMT lines for PCB assembly production.

Through-Hole Assembly

Larger power devices, transformers, connectors and capacitors may require DIP or through-hole assembly.

Depending on the inverter design, SMT and THT processes can be combined within the same PCBA project.

Component Sourcing

AVPCB can support BOM sourcing together with PCB fabrication and assembly, reducing the need to coordinate separate PCB and electronic component suppliers.

Quality Inspection and Testing

Inverter PCBA Quality Control

Quality control can be performed at different stages according to the PCB structure, component type and customer testing requirements.

Available inspection methods include:

AOI Inspection

Automated optical inspection can identify:

• Missing components
• Incorrect placement
• Polarity errors
• Solder bridges
• Soldering abnormalities

X-Ray Inspection

X-ray inspection can be used for packages with hidden solder joints where required.

Flying Probe Testing

For suitable PCB projects, flying probe testing can be used to verify electrical continuity and circuit connections.

Functional Testing

Functional testing can be carried out according to customer-provided test procedures, test fixtures and acceptance requirements.

Applications

Off-Grid Solar Inverters

Suitable for PCBA projects used in battery-based and off-grid solar power systems where DC power needs to be converted into AC power.

Backup Power Systems

Inverter PCBs can be integrated into backup power equipment and battery-powered AC supply systems.

Portable Power Systems

Custom inverter PCB assemblies can be used in portable power and mobile energy systems according to voltage, power and thermal requirements.

Automotive and Marine Power Conversion

12V and 24V battery systems are widely used as power sources in vehicle and marine electrical environments.

However, PCB material, protection, vibration resistance and environmental requirements should be specified according to the final application.

Renewable Energy Equipment

Inverter PCBAs can also form part of energy-conversion and battery-based renewable power equipment.

Custom Inverter PCB Assembly

AVPCB supports custom inverter PCB and PCBA manufacturing based on customer design requirements.

Customization can include:

• PCB dimensions
• Board thickness
• Copper thickness
• Layer count
• PCB material
• Surface finish
• Power component selection
• SMT and THT assembly
• Component sourcing
• Connector configuration
• PCB color
• Functional testing
• Packaging
• Prototype and production quantities

If your project requires a different input voltage, output specification or power rating, send the complete design and manufacturing requirements for engineering review.

Prototype to Volume Production

AVPCB supports inverter PCBA projects from engineering samples and prototypes to batch production.

Prototype builds can be used to verify:

• PCB layout
• Component placement
• Connector position
• Assembly process
• Electrical operation
• Thermal behavior
• Mechanical fit

Once the design has been validated, the same manufacturing documentation can be used for repeat production subject to BOM and component availability.

FAQ

Can AVPCB manufacture custom solar inverter PCB assemblies?

Yes. AVPCB provides PCB manufacturing, component sourcing, SMT/DIP assembly and testing services for custom PCBA projects based on customer production files.

Can you manufacture 12V and 24V inverter boards?

This product configuration is intended for inverter designs using 12V or 24V DC input and 220V AC applications. The exact electrical specifications must be confirmed from the customer’s circuit design.

Can you manufacture higher-power inverter PCB assemblies?

Power capability depends on the complete PCB and electrical design, including copper weight, trace dimensions, component selection, thermal management and mechanical structure. Send the design files for manufacturability evaluation rather than selecting only by voltage.

Do you support SMT and through-hole assembly?

Yes. AVPCB provides both SMD/SMT and DIP assembly services.

Can you source components for inverter PCBA production?

Yes. Component sourcing is included in AVPCB’s one-stop PCB and PCBA manufacturing services.

What files are required for a quote?

For PCBA projects, Gerber files, BOM and assembly-related files are recommended. For PCB or PCBA copy projects, a physical sample and available technical information can also be provided.
