PCB OEM Manufacturing and 9 Case Sharing in 2024

What is PCB OEM? It's an acronym for printed circuit board original equipment manufacturing.

PCB OEM is custom flexible manufacturing. From the PCB OEM manufacturer PCBONLINE, the manufacturing service range includes:

• PCB fabrication,
• component sourcing,
• PCB assembly,
• value-added services (IC burn-in, conformal coating, thermal aging, functional testing),
• and end product box build assembly.

You will explore the PCB OEM manufacturing process and 9 real OEM PCB cases from PCBONLINE below.

Part 1. PCB OEM Manufacturing Process

Imagine you have designed a PCB and a matching enclosure for it, or you have a project plan but lack enough R&D capabilities; what is the PCB OEM manufacturing process when you reach out to a PCB OEM manufacturer?

Check the PCB OEM manufacturing process easily from PCBONLINE.

Stage 1. DFM and pre-sales services

When you contact PCBONLINE, either through online chats, emails to info@pcbonline.com, or sending your messages via the contact form, you will receive quick replies.

If you have a Gerber and other documents such as a BOM (bill of materials), send it to PCBONLINE. The engineers from PCBONLINE will check your documents to make sure the manufacturability of the design.

Gerber and BOM checks are part of DFM or design for manufacturing. It is free at PCBONLINE.

At the pre-sales stage, PCBONLINE can select alternative components to replace the expensive ones with the same functions and certification. As components cost the most in PCB OEM manufacturing, it can reduce your project's fabrication costs dramatically.

What about if you don't have a design yet and need R&D from the OEM PCB manufacturer?

It is no problem for PCBONLINE, the OEM PCB manufacturer with all-around R&D capabilities.

PCBONLINE will ask for the necessary specs and comprehensive requirements of the product you want to turn into reality. Software, circuit diagrams, PCB layout, enclosure design, and manufacturing and testing process can all be done by PCBONLINE.

Will there be R&D fees?

Yes. However, once your project goes to batch production, PCBONLINE will refund the R&D fees to you.

Stage 2. Prototype and sampling

After the Gerber and BOM checks, the OEM PCB manufacturer PCBONLINE starts PCB prototyping.

During the prototyping and sampling stage, PCBONLINE will manufacture and assemble a small quantity of PCB boards. For quality consistency, the production lines are the same as batch production.

With the PCBA sample, PCBONLINE will have the functional test, IC burn-in, and box-build assembly to make the final product sample.

PCB prototyping and sampling are part of the entire device manufacturing process. During this stage, technical and unexpected issues may occur. Fortunately, the OEM PCB manufacturer PCBONLINE has rich experience solving issues and ensures hassle-free manufacturing of the OEM PCB project.

Stage 3. PCB fabrication

The PCB fabrication process includes:

• Cut laminate,
• Inner layer circuits,
• Lamination,
• Drilling,
• Copper plating,
• Outer layer circuits,
• Circuit pattern plating copper,
• Etching,
• Solder mask,
• Legend (silkscreen),
• Surface finish,
• Profiling (Outline routing),
• Electrical testing,
• Final quality control.

Meanwhile, PCBONLINE designs the SMT stencil and jigs for PCB assembly and has them manufactured by the mold factories in long-term cooperation.

For OEM PCB projects that need box-build assembly, PCBONLINE works with the top 3 enclosure factories in China to manufacture the enclosures.

Stage 4. PCB assembly

The PCB assembly process includes SMT assembly and PTH assembly. SMT is fully automatic, and PTH is half-automatic.

The SMT process includes:

• Solder paste printing,
• Solder paste inspection,
• Placing SMD components,
• X-ray inspection,
• Reflow soldering,
• And automated optical inspection (AOI).

The PTH assembly process includes:

• Inserting the PTH component lead through the PTH holes,
• And wave soldering.

Stage 5. PCBA value-added

PCBONLINE provides PCBA value-added services in the post-assembly stage. It further extends the service life of the PCBA and saves your efforts afterward, as you don't need to connect with your local factories to disassemble your products to do the value-added things on the PCBA.

The PCBA value-added services from the OEM PCB manufacturer PCBONLINE are comprehensive:

• Conformal coating: Spraying a urethane/polyurethane coating on the PCBA surface to keep it from moisture, chemicals, vibration, and thermal shocks. It extends the service life of the PCBA.
• IC burn-in: Transferring the program into the blank IC mounted of the PCBA. It enables the ICs, such as the microcontroller, BGA, FPGA, and so on, to operate and control the system.
• Thermal aging: Keeping the PCBA powered on for 48 to 240 hours to prove that the PCBA can withstand long-term work without being affected.
• Functional testing: Place the PCBA on a jig for electrical and function testing to ensure the PCBA can work as expected.

Step 6: Box-build assembly and application testing

At the OEM PCB assembly factory of PCBONLINE, our technicians install the cables and enclosure on the PCBA, tighten the screws, and print your brand logo according to your requirements. Now, the OEM PCB project is almost at the end.

However, despite the comprehensive tests and inspections during PCB assembly and post-assembly stages, we still need to ensure the end product's functions and quality.

So, the OEM PCB manufacturer PCBONLINE will simulate the application environment to test the functions and quality of the product and record the results for you to review.

When everything is ensured to be good, we will package the box builds according to your requirements and ship them to you.

The complete PCB OEM manufacturing is above. As you can see, it can cover everything for electronics manufacturing.

Are there any PCB OEM examples? Yes.
