Metal core pcb manufacturer Explains the Basic Types of pcbs (Mcpcbs china 2020)

From the perspective of metal core PCB or MCPCB, aluminum PCB is one of the most popular and commonly used MCPCB. MCBPC’s specialty lies in the ability to provide efficient heat dissipation for electronic products. And this is not possible without a professional metal core pcb manufacturer.

 What is a metal core pcb?

The aluminum printed circuit board consists of a standard aluminum inner core composed of FR4. The main feature of aluminum PCB is its thermal cover layer. Moreover, it effectively dissipates heat. This function can cool the components and improve the overall performance of the product. Aluminum support PCBs are the first choice for high power applications with tight tolerances.

Printed circuit boards (PCBs) are very common in various equipment in industries such as:

• Automobiles
• Telecommunications
• Aerospace
• Military
• and healthcare.

Therefore, metal core pcb manufacturer and supply are common in various applications and purposes. We can classify these printed circuit boards according to various parameters. This article provides an introduction to distinguish different types of printed circuit boards (PCBs) through different parameters.

How does metal core pcb manufacturer classify pcbs?

We can classify Circuit boards in different ways, but the following categories are more common:

Classification based on substrates: According to the use of substrates, printed circuit boards (PCBs) divides into rigid, flexible and rigid-flex PCBs.

The Classification based on layers: 1 layer, 2 layer, 4 layer, multilayer.

Classification based on materials: According to the materials used for construction, PCBs divides into FR4 PCBs and metal core PCBs.

Overview of different types of PCBs based on substrates

Substrate-based characterization mainly focuses on three types of printed circuit boards (PCB), as described below:

Rigid PCB: metal core pcb manufacturer makes rigid PCB is manufactured using a solid material substrate. Subsequently, this strong substrate prevents the rigid PCB from twisting or bending. These are probably the most common and PCBs. Because, a lot of electronic devices, use rigid pcbs these days.

The number of layers is not a limitation of the printed circuit board. Hence, it can be a single layer or 10 layers. Glass fiber is a common manufacturing material used to manufacture rigid PCBs. Moreover, it has better safety because it can prevent distortion. So we can keep the installed components in place. Computer motherboards are the most common example of such PCBs.

How does metal core pcb manufacturer develop flexible pcbs?

Flexible PCB: Different from rigid PCB, flexible PCB is made of flexible substrate, hence the name. It can be available into:

• single layer
• double layer or
• multilayer, and
• has a flexible backing.

The biggest advantage of these flexible PCBs is flexibility. A metal core pcb manufacturer can fold them according to the convenience of the application.

These PCBs come with flexible substrates. Moreover, these are:

• Waterproof
• corrosion resistant and
• Temperature efficient.

They are ideal for applications requiring high bend and flexibility. Over the years, flexible PCBs have gained tremendous popularity due to their flexible characteristics and compatibility with any type of components or connectors. The most common applications of flexible PCBs are in portable electronic devices, desktop printers, hard drives, etc.

Rigid Flex Metal Core Pcbs

Rigid-flex PCB: Rigid-flex PCB is a combination of the above-mentioned types of PCBs. These circuit boards develop by laminating flexible conductive layers on rigid PCBs. The advantage of this type of PCB is that it provides a simplified design and reduces the weight and size of the PCB.

Like flexible PCBs, these rigid-flex PCBs can also withstand high temperatures and harsh working environments. Similarly, the common applications of such PCBs are digital cameras, automobiles, mobile phones, pacemakers, etc.

According to the design, structure, materials, etc. of the printed circuit board, the printed circuit board have multi functions. The above focuses on different types of printed circuit boards based on substrates.

The next focus is on layer-based and material-based PCBs. These two are important categories for metal core pcb manufacturer.

What are the different types of layer-based PCBs? metal core pcb manufacturer

The layer-based distinction takes into account the number of layers on the PCB. The combination of the conductor film and the prepreg can form a laminate/chapter, and the number of laminates can form a book. Therefore, the number of chapters or layers in the PCB determines the type of layer-based PCB.

Single-layer or single-sided PCB: Single-layer PCB comes with only one layer of material substrate. The layer of substrate or core material coats with a thin film of conductive material. Generally, the conductive layer is a copper (Cu) film.

Finally, a silk screen covers the copper layer to mark the components on the board. This is the simplest form of PCB and is usually used for DIY applications and prototypes. Common applications for single-layer PCBs are in radio equipment, LEDs, etc.

Double layer metal core pcbs

Metal core pcb manufacturer creates 2 layer pcb using laminate and conductive material. Drill holes on each layer to achieve through-hole PCB assembly. Thin wires called leads are passed through the holes and then soldered to the appropriate components.

Moreover, it has the advantage of connecting circuits or components in two ways: surface mount or through-hole connection. Although wiring is not important in surface mounting, the double-layer board itself serves as the wiring surface for the component. Common applications for double-layer PCBs are:

• vending machines
• lighting systems
• car dashboards and

Multilayer PCB: Multilayer PCB is a further development of double layer PCB. Similar to a double-layer PCB, but with multiple layers added on both sides of the substrate. This allows PCB designers and manufacturers to develop complex and thick PCBs.

The advantage of a multi-layer PCB is that there is less electromagnetic interference and can provide equivalent power distribution. This will minimize the damage to the connection cable. These PCBs are common in complex devices such as:

• Computers
• heart monitors
• interactive displays
• Automobiles, etc.

Overview of different types of PCBs based on materials: Metal core pcb manufacturer

According to the Metal core pcb manufacturer, PCB develops with different material composition. The following are the types of printed circuit boards classified by material.

FR4 PCB: FR4 PCB is suitable for applications where fire resistance is important. Similarly, in FR4, the term FR stands for flame retardant and 4 stands for woven glass fiber with epoxy resin. These PCBs are made of glass fiber and epoxy resin, making them flame retardant. Due to its multiple economic and mechanical advantages, this is the most common type of PCB used today.

Metal core PCB: The material substrate used in these metal core PCBs is aluminum, copper and steel alloys. Metal core pcb manufacturer uses it for various purposes (such as good heat dissipation). We can develop these PCBs with any number of layers based on the form of the substrate. Metal core PCBs are widely popular in LED systems and modern electronic products.

Conclusion Metal core pcb manufacturer

Why we need Metal core pcb manufacturer? In modern world the technology is improving. Therefore, there are tough devices. These devices require high end performance from pcbs. To meet this hard core performance, the role of metal core pcb is crucial.

Both FR4 and metal core PCB can be designed as single-layer, double-layer or multi-layer PCB or rigid-flex PCB according to application requirements. As each type of PCB has its own characteristics, it is very important to choose a manufacturer or supplier wisely.
