Multilayer PCB Manufacturing Process

In making multilayer PCBs, we pay close attention to every step to make sure they are top-notch.

We start by designing where the circuits will go, then drill holes for the parts to fit in. We keep a close eye on each stage to ensure the PCBs work well for all kinds of electronic gadgets.

You can trust our process because making high-quality PCBs for our customers is what we’re all about. Here’s how we do it:

Advantages Of Multilayer PCB Over Single and Double Layer PCB

All of these PCBs are good choices. How you decide to go with a multilayer or single-layer structure depends on what type of product you need to produce. Essentially, if you want to produce complex devices that are small, lightweight, and require high quality, a multilayer PCB may be your best choice. However, if size and weight are not important factors in your product design, a Single or Double Sided PCB design may be more cost effective.

We support 4-48 layers multilayer pcb fabrication.

Multilayer boards have emerged with the development of the electronics industry. Because there is some advanced equipment, single-sided or double-sided PCB can not meet. Multilayer boards is lighter, smaller, and features higher operation speed than traditional printed circuit boards. All the advantages make them appropriate to be used in high-end electronic equipment like handheld devices, test equipment, heart monitors, etc.

And the preference for multilayer circuit board is still largely dependent on industry trends. Electronics continue to move toward versatility and are small, thin, and lightweight. So single and double sided PCBs can no longer meet the changing needs. And their ability to balance size and functionality has proven limited, but multilayer PCBs offer a comprehensive solution.

While there are several drawbacks to using multilayer boards, such as increased cost, design time, and production investment, these costs are increasingly accepted in today’s world. Functionality is largely favored over price, and people are willing to pay more for high-capacity electronics. In addition, as technology becomes more mainstream, production techniques and machines will eventually become cheaper, especially as new technologies enter the industry.

Multilayer PCBs feature three or more layers of conductive copper foil buried in several layers. It is laminated and glued between each layer with a thermally protective insulating layer. It finally appears as a double-sided circuit board with several layers. Multilayer boards have various through-holes for all electrical connections. These types of vias include blind and buried vias and plated vias. This is the simple definition of multilayer boards.

Compared with single-sided or double-sided PCBs, multilayer boards have higher assembly density, flexibility.

Advantages:

High efficiency: Its enable more advanced design, manufacturing, and assembly techniques. So their inherent electrical characteristics allow them to achieve greater capacity and speed.

High Durability: Its use multiple layers of insulation between circuit layers. They are bonded together using prepreg adhesives and protective materials, making them more durable than standard PCBs.

Smaller size and lighter weight: Its use stacking and lamination techniques, resulting in smaller and lighter weight boards. This is one of its most prominent and highly acclaimed benefits.

Single connection point: Its use a single connection point that can be designed to work together on a board. This particular design simplifies the complex design of electronic devices and reduces size and weight.

Disadvantage:

High cost: Making a multilayer board is much higher than that of a regular pcb. Because multilayer pcb manufacturing machines are very expensive, it is still a relatively new technology.

Narrow application range: Multilayer pcb fabrication requires specialized multilayer pcb manufacturing machines, which not all multilayer pcb suppliers have the funds or need.

Long production time: Each board of a multilayer pcb fabrication requires a lot of time, which leads to more labor costs.
