Multilayer PCB Assembly

Multilayer PCB is defined as a circuit board that has more than two layers. In single or double-sided PCB, we have only one and two conductive layers of materials respectively. Multilayer PCBs will be having at least 3 layers of conductive materials that are buried in the centre of the material.

Multilayer PCB assembly has a higher operating capacity and can run even at higher speeds. They achieve durability while still maintaining a relatively small size and low weight. With additional layers, the board is thicker and sturdier than single-sided PCB.

Manufacturing multilayer PCBs require specialized equipment and a significant amount of commitment. This usually delays the time-to-market. Hence go for an advanced contract manufacturer who has enough experience in providing the expanded capabilities for supporting multilayer PCBs. You can look at their service, manufacturing capabilities, quality control, customization, responsiveness, and turnaround time.

Mer-Mar Electronics is a US-based PCB fabrication CM that is ITAR compliant and has over 4 decades of experience. We follow a client-centric approach and guarantee quality satisfaction. You can have lead-free components and RoHS compliant designs that come at competitive prices and quick turnaround times. We also have a proven and demonstrated capability to work with a variety of materials.

You may require multilayer circuit boards in the following scenarios –

• Shielding Applications
• Controlled Impedance with Shielding
• EMI/RFI shielding
• Ground and power plane applications
• Increased circuit density

The turnaround time for a multilayer PCB depends on the supplier or contract manufacturer you choose. It also depends on the complexity and quantity of the project. At Mer-Mar Electronics, we have in-house capabilities who can take up everything from design to final completion allowing us to deliver turnarounds in the least time possible. We also rely on dedicated supply chains and advanced tools like a 3D printer for expediting the process and for rapid prototyping.

Multilayer PCBs require complex processes when compared to the single- or double-layer designs. You need to have experienced professionals for handling complex and accurate manufacturing processes. They are a tad expensive as well owing to the lamination and epoxy materials.

Of course, we can. Our designers have enough knowledge of the multilayer designs. We also have an idea about ground shielding, impedance control, and also good layer stack designs. With multiple layers, we found the ease of design process and also finish the design process early.

The multilayer PCBs are beneficial for multiple industries and for several other applications like file servers, GPS tech, satellite systems, cell phone transmitters, weather analysis, X-ray equipment, space probe equipment, hand-held devices, wearable devices, central fire alarm systems and many more.

Definitely, multilayer PCB assembly is a bit costlier when compared to the traditional PCB assembly. However, make sure you have specifications right and request only those that are needed. Any deviations from the actual standards and requirements are going to unnecessarily increase the costs as well. Also, remember that we reduce human error via design accuracy and production automation.

To manufacture the range of multilayer PCB assembly, it involves the process of combining alternating layers of prepreg and core materials into a single unit with high pressure and heat to ensure uniform encapsulation of conductors.
