The modular PCBA (printed circuit board assembly) provides electronic products and systems with greater flexibility and customization. The modules can be added, removed, and replaced as needed, so they are an ideal solution for a wide range of applications.

modular PCBA

LED, control motherboard, image processing, audio decoding, Bluetooth, WiFi, and communication modules are common modular PCBAs. As a one-stop PCBA supplier, we have had rich experience in manufacturing these modular PCBs and PCBAs. Below are some examples of modular PCB and PCBA and knowledge we want to share with you.

Bluetooth, WiFi, and Communication Modular PCBs

Bluetooth, WiFi, and communication modules are very common. They are used in communication, computing, automotive, and consumer applications. However, it is a little tricky in their PCB assembly. On the edges of Bluetooth, WiFi, and communication modular PCBs, are half-holes that need soldering. During PCB assembly, it is difficult for the solder paste to fully wet the pads, and this can cause cold solder or pseudo-soldering.

It is easy to solve this Bluetooth, WiFi, and communication module PCB assembly issue. At PCBONLINE, when we make PCB design for manufacturing (DFM) for Bluetooth, WiFi, and communication modular PCBs, we design the step-up stencil or Nano stencil for PCB assembly instead of normal SMT stencils. By using a step-up or Nano stencil for SMT assembly, the solder paste can wet the pads for half holes and ensure solderability.

LED Modular PCBA

LED modules are the most critical part of an LED light and indicator. Their applications include street lights, home lighting, automotive lighting, industrial lighting, maritime lighting, etc.

In LED PCB fabrication, the substrate materials are typically high thermal conductivity materials, such as aluminum, ceramic, and copper.

The whole manufacturing process of COB LED modular PCBAs includes chip sourcing, PCB fabrication, LED chip wiring bonding or flip-chip assembly on boards, testing, sealing glue to COB LEDs, and adjusting RGB (red, green, blue) colors.

SMD Aluminum LED modular PCBA

aluminum LED PCBA

This is an aluminum LED modular PCBA designed and manufactured by us. It is a 100W LED module used for boat lighting on the sea. It has 12 LED beads that are 8W. The beads include 6V and 12V. The 6V-bead flows 1.2mA current, while the 12V-bead flows 0.7mA. Each LED bead has 4 chips that are 6V and 9V. The 6V chip is 2-paralleled and 2-stringed, while the 9V chip is 1-paralleled and 4-stringed. This aluminum LED modular PCBA has 7878 lumens and a color temperature of 7515K.

COB ceramic-inlay copper-base LED Modular PCBA

COB LED PCBA

This is a COB LED PCBA used for stage lights. It has a composite structure. Its PCB base is copper. In the center of the LED module, an aluminum nitride LED module inlays. In the middle of the ceramic LED module, the light source COB LEDs are flip-chip bonded on the board.

Audio and Video Decoding Modular PCBA

This is an audio and video decoding motherboard with the CAN communication function. CAN is a controller area network bus for networking intelligent devices for automotive and industrial uses.

On the modular PCBA, there's an FPGA, which generates plenty of heat when the board works. To protect the PCBA from overheating, we place a heat sink, the large black part next to the FPGA. The heat sink dissipates thermal quickly and ensures that the core components of the board work more stably and efficiently.

Image Processing Modular PCBA

This is an image-processing modular PCBA used for face recognition and IoT intelligent cameras. As you can see, a module PCB has two half holes on its edges, and its assembly is fine-pitch. The minimum component footprint is 01005.

PCBONLINE manufactured 1,000 modular PCBAs, and the order had 0 return work. The client felt pleasant and said in his email, "PCBONLINE provides high-quality PCB assembly with the proficient placement of 01005 components. Your business and production departments cooperated vigorously to ensure these motherboards' quality and delivery time. We are very satisfied with this cooperation. We look forward to seeing more surprises from PCBONLINE in the future."

Control Modular PCBA

If you want modular PCBA, send your Gerber, BOM, and pick-and-place file to info@pcbonline.com.

Conclusion

Electronics manufacturing can be easy with a reliable modular PCBA manufacturer. No matter how complex the circuit of the module is, it is made from assembling components on bare printed circuit boards. However, the assembly details vary according to different components, PCB holes, and PCB substrates. If you need modular PCBA, work with a source factory manufacturer, who offers the most cost-effective PCBA.
