Custom PCB Assembly Services by Omini

What is Custom PCB Assembly?

Omini specializes in custom PCB assembly, catering to industries that require tailored solutions for their electronic products. Just like the sophisticated technology in electric cars—featuring autonomous driving, infotainment, and advanced sensors—custom PCBs form the backbone of these innovations. These boards provide physical support and electrical interconnections for various components, enabling the seamless integration of complex systems.

While “off-the-shelf” PCBs are a cost-effective option, custom PCBs are designed and fabricated based on specific customer requirements and application needs. Custom PCB assembly refers to the process of converting schematic designs into physical PCBs, selecting appropriate materials, and populating them with components. Omini combines design and manufacturing expertise to ensure precision and efficiency in the assembly of custom PCBs.

Customized PCBs are increasingly in demand across various sectors, including medical, automotive, telecommunications, industrial, IoT, and robotics. As the world becomes more dependent on advanced electronics, custom PCB assembly services are critical for companies seeking tailored solutions. In this context, Omini’s custom PCB assembly services cater to the growing global market, particularly in China, which has become a key hub for high-quality PCB manufacturing.

What Are the Different Types of PCBs?

Understanding the different types of printed circuit boards (PCBs) is crucial before diving into custom PCB assembly. Omini offers a wide range of PCB solutions, each with its own unique features and applications.

1. Single-sided PCB:
This type has the circuit pattern on one side of the board only, making it the simplest and most cost-effective option. Ideal for low-density designs and basic applications.

2. Double-sided PCB:
Both sides of the PCB are used for circuit patterns, allowing for higher component density compared to single-sided PCBs. It’s a popular choice for medium-complexity designs.

3. Multi-layer PCB:
With increasing design complexity, multi-layer PCBs offer several stacked layers of circuitry separated by prepreg materials. These are used for high-density, high-performance applications.

4. Rigid PCB:
The most common type of PCB, rigid PCBs are made from stiff dielectric woven glass materials. They offer solid mechanical strength and are widely used in consumer electronics.

5. Flexible PCB:
Made from thin, flexible substrates, flexible PCBs offer excellent thermal and electrical performance. They are commonly used in applications like mobile phones and cameras where space is limited.

6. Rigid-flex PCB:
Combining rigid and flexible circuits, rigid-flex PCBs offer both structural integrity and flexibility. They can be single-sided, double-sided, or multi-layer, making them suitable for compact, high-performance devices.

Omini provides expert solutions in each of these PCB types, ensuring that your design is met with the right board for optimal performance and cost efficiency.

Benefits of PCB Customization

2. Cost Optimization:
Customization allows for cost-effective solutions by selecting materials based on functionality and application needs. Omini ensures that you get the best value by optimizing material choices to reduce overall production costs.

3. Improved Efficiency:
Custom PCBs streamline design and production by focusing on essential functions and eliminating unnecessary components. This results in a more efficient PCB, optimized for performance and reducing complexity.

4. Enhanced Performance:
Omini’s custom PCBs optimize performance by reducing noise and improving signal integrity. A detailed design approach, including careful component placement and signal routing, ensures superior functionality and reliability, making your product stand out in the market.

Steps of Custom PCB Assembly

Omini follows a comprehensive process to ensure high-quality custom PCB assemblies that meet your specific needs. Here’s an overview of the key steps involved:

1. Schematics and Layout Design
The custom PCB assembly process begins with creating a CAD file that specifies component locations and feeder positions. This data is then processed into a manufacturing file format for automatic assembly, ensuring precise alignment and functionality.

2. Solder Paste Printing
Solder paste is applied to the PCB using stencil printing, where a squeegee evenly distributes the paste onto the board. This is a critical step, as more than 50% of soldering defects are linked to paste printing. Proper optimization ensures high first-pass yields and minimizes common issues like solder bridging.

3. Solder Paste Inspection (SPI)
To ensure high-quality solder joints, the volume of solder paste is measured using an automatic optical inspection (AOI) system. This step ensures uniform paste application and identifies defects, enhancing the reliability of electrical connections between components and the PCB.

4. Component Placement
High-speed placement machines automatically position components of varying types and sizes onto the PCB. These machines ensure accurate placement, though potential issues such as misalignment can occur. Proper adjustments are made to minimize shifts, ensuring components are aligned for reflow soldering.

5. Solder Reflow
The assembled PCB enters a reflow oven, where the solder paste is melted to form strong electrical connections. The reflow process involves four stages: pre-heating, soaking, reflow (melting solder), and cooling. A carefully controlled thermal profile ensures the highest quality solder joints and secure component attachment.

6. Automatic Optical Inspection (AOI)
Omini uses AOI systems to detect defects in custom PCB assemblies. This advanced system scans the board, compares the images to reference standards, and accurately identifies abnormalities, ensuring a high-quality, reliable product that meets industry standards.

These steps are vital in delivering efficient, precise, and high-performance custom PCB assemblies tailored to your specific needs. Omini’s expertise in each stage ensures optimal results for your projects.

Things to Consider in Selecting a Custom PCB Assembly Supplier

1. Price Competitiveness
Price is a critical factor in selecting a custom PCB assembly supplier. Omini offers competitive pricing, ensuring cost efficiency without compromising quality. Factors like layer counts, material choice, size, and design complexity influence costs. Custom PCB suppliers in China, like Omini, often provide more cost-effective solutions than those in Europe, making it an excellent choice for your custom assembly needs.

2. Lead Time and Logistics Considerations
Quick turnaround times are crucial in custom PCB assembly. Omini ensures fast lead times based on your project’s complexity and quantity. Understanding the full PCB assembly process, from fabrication to final assembly, helps you manage delivery expectations. With strong logistics support, Omini guarantees reliable delivery within agreed timelines.
