Multilayer PCB Materials: Key to Performance and Reliability

In multilayer PCB manufacturing, the choice of materials directly affects electrical performance, thermal stability, and product reliability. Each layer in a multilayer PCB stack-up plays a specific role, and understanding the materials used is essential for optimal design and production.

Core and Prepreg

The foundation of any multilayer PCB is the combination of core and prepreg.

Core is a rigid double-sided laminate made of fiberglass-reinforced resin, usually FR-4, with copper foil on both sides. It provides mechanical strength and supports internal circuitry.

Prepreg is a fiberglass material pre-impregnated with partially cured resin. It is placed between layers during lamination and bonds them together when heat and pressure are applied. Prepreg also serves as insulation between conductive layers.

Common prepreg and core materials include standard FR-4, high-Tg epoxy, polyimide, and halogen-free options.

Copper Foil

Copper is the conductive material that forms the signal layers, power planes, and ground planes in a PCB. It comes in different thicknesses depending on the current requirements. Typical copper thicknesses include 17 microns (0.5 oz), 35 microns (1 oz), and 70 microns (2 oz) per square foot.

There are two main types of copper foil: electrodeposited (ED) copper, which is more economical, and rolled annealed (RA) copper, which is more flexible and used in applications with fine-pitch routing or bending requirements.

Dielectric Materials

Dielectric materials provide electrical insulation between conductive layers. They also influence signal speed, impedance control, and overall board performance.

FR-4 is the most commonly used dielectric in general-purpose PCBs. It is cost-effective and provides adequate thermal resistance for standard applications.

For high-temperature or high-frequency applications, designers often use high-Tg FR-4, polyimide, or PTFE-based materials like Rogers. These advanced materials offer better thermal performance, lower signal loss, and improved stability in harsh environments.

Halogen-free materials are also increasingly popular in eco-friendly and flame-retardant applications.

Solder Mask and Surface Finishes

The solder mask is the colored layer that protects copper traces from oxidation and prevents solder bridging during assembly. Green is the most common color, but others like red, blue, black, and white are also available.

Surface finishes are applied to exposed copper areas such as pads to ensure good solderability and prevent oxidation. Common finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative).

Material Selection Tips

When selecting materials for a multilayer PCB, engineers consider several factors:

Electrical performance, including signal integrity and impedance control.

Thermal resistance for environments with high operating temperatures.

Mechanical strength and layer count, especially in thicker or rigid-flex designs.

Cost, availability, and compatibility with manufacturing processes.

Choosing the right material combination helps ensure long-term reliability and performance of the final product.

Final Thoughts

Multilayer PCBs are the backbone of modern electronic systems, and material selection is at the core of their success. By understanding the properties and applications of different PCB materials, designers and engineers can make better decisions and achieve more efficient, durable, and high-performance designs.

PCB Manufacturing: A Comprehensive Guide to Printed Circuit Board Production

Introduction to PCB Manufacturing

PCB manufacturing is the process of creating printed circuit boards, which are essential components in nearly all modern electronic devices. From smartphones to industrial machinery, PCBs provide the foundation for electrical connections and component mounting. This guide explores the PCB manufacturing process, materials, technologies, and applications.

The PCB Manufacturing Process

1. Design and Schematic Creation

Before production begins, engineers design the PCB using specialized software like Altium Designer, KiCad, or Eagle. The design includes:

Schematic diagrams (circuit connections)

Component placement

Trace routing (copper pathways)

Layer stack-up (for multi-layer PCBs)

Once the design is finalized, a Gerber file (standard PCB manufacturing file) is generated for fabrication.

2. Material Selection

The base material of a PCB is typically FR-4, a flame-resistant fiberglass epoxy laminate. Other materials include:

Flexible PCBs: Made from polyimide for bendable circuits.

High-frequency PCBs: Use Rogers material for RF applications.

Metal-core PCBs: Aluminum or copper for heat dissipation.

3. Printing the Circuit Pattern

The PCB design is transferred onto the board using one of these methods:

Photolithography: A UV-sensitive photoresist is applied, exposed to UV light, and developed to create the circuit pattern.

Direct Imaging: A laser directly etches the pattern onto the PCB.

4. Etching the Copper Layers

After the circuit pattern is printed, the unwanted copper is removed through chemical etching. The remaining copper forms the conductive traces.

5. Drilling Holes for Components

Precision CNC machines drill holes for through-hole components and vias (connections between layers).

6. Plating and Copper Deposition

The drilled holes are electroplated with copper to ensure conductivity between layers.

7. Solder Mask Application

A solder mask (usually green) is applied to protect the copper traces and prevent short circuits. Openings are left for soldering components.

8. Silkscreen Printing

Text, logos, and component labels are printed on the PCB using silkscreen ink for easy assembly and identification.

9. Surface Finish Application

A surface finish is applied to protect exposed copper and improve solderability. Common finishes include:

HASL (Hot Air Solder Leveling)

ENIG (Electroless Nickel Immersion Gold)

OSP (Organic Solderability Preservative)

10. Electrical Testing and Quality Control

Each PCB undergoes automated optical inspection (AOI) and electrical testing to ensure functionality. Defective boards are rejected.

Types of PCBs in Manufacturing

1. Single-Layer PCBs

Simplest and most cost-effective.

Used in basic electronics like calculators.

2. Double-Layer PCBs

Conductors on both sides.

Common in consumer electronics.

3. Multi-Layer PCBs

The difference between copper base PCB, fake double-sided copper base PCB and true double-sided copper base PCB

Copper base PCB is the best heat dissipation and the most expensive circuit board among metal-based PCBs. Generally, copper base PCB include single-sided copper PCB, double-sided copper base PCB, and fake double-sided copper base PCB. The specific advantages of copper base PCB make them widely used in areas with large changes in high and low temperatures, as well as in the precision communication equipment and LED car light markets. The pad production processes of copper substrate manufacturers generally include immersion gold, OSP, HASL, immersion silver, etc.

Authenticity of true and false double-sided copper base PCB

Fake double-sided copper base PCB are generally designed by customers with two layers of circuits, but they are not connected to each other. The real double-sided copper base PCB is the double-sided circuit layer designed by the customer with vias connecting the two-sided circuits.

The copper base PCB, circuit layer requires a large current carrying capacity, so a thicker copper foil should be used, with a thickness of generally 35μm~280μm; the thermal conductive insulation layer is the core technology of the copper substrate. The core thermal conductive component is composed of aluminum oxide and silicon powder and a polymer filled with epoxy resin. It has a small thermal resistance (0.15), excellent viscoelastic properties, and is resistant to thermal aging and can withstand mechanical and thermal stress.

The copper substrate metal base is the supporting component of the copper substrate. It is required to have high thermal conductivity. It is generally a copper plate. Copper plates can also be used (copper plates can provide better thermal conductivity). It is suitable for conventional mechanical processing such as drilling, punching and cutting.

The structure of the real and fake double-sided copper substrate can be divided into 5 layers: 1 layer is the top copper foil, 2 layers are thermal conductive insulation materials, 3 layers are aluminum plates, 4 layers are bottom insulation materials, and 5 layers are bottom copper foil. Their functions are as follows:

The 1st layer of copper foil is used as the top circuit pattern (conductive).

The 2nd insulating layer is also the key layer to reflect the thermal conductivity, also known as the thermal conductive layer, which plays a dual role of thermal conductivity and insulation. Whether the heat generated by the LED lamp can be quickly transferred to the aluminum plate, it is necessary to know the thermal resistance of the thermal conductive insulating material.

The function of the 3rd layer is to transfer the heat conducted by the thermal conductive insulating material to the lamp cup again. There is also an installation function.

The functions of the 4th and 5th layers are the same as those of the 2nd and 1st layers above.

Through the above structure, we can easily understand the thermal conductivity and heat dissipation principle of the copper base PCB. In addition, the special process of copper base PCB processing and the thermoelectric separation production technology have improved the thermal conductivity of the copper base PCB by several times. Therefore, most designers who make LED copper base PCB now design a thermoelectric separation thermal conductivity method to make the heat dissipation performance of the copper base PCB better.

Where Can I do FPC Flex PCB Assembly?

https://www.grande-pcba.com/where-can-i-do-fpc-flex-pcb-assembly/Grande has its own PCB Fctory and SMT Assembly factory, which can provide FPC Flex PCB Fabrication and FPC PCBA Manufacturing services!

Flex PCB Assembly Capability

Number of Rigid-Flex PCB / Flex PCB Layers: 10/6;

Minimum Trace Width & Spacing: 3/3mil;

Board Thickness Aperture Ratio: 12:1;

Distance From Hole to Conductor: 6mil;

Impedance Tolerance (Ω): 10%;

Surface Finish: Chemical immersion gold, immersion tin, HASL, hard gold plating, soft gold, silver paste, etc.

Common Types of Flex PCB

At present, Flex PCB has four types: Single-Sided FPC, Double-Sided FPC, Multilayer Flex PCB & Rigid-Flex PCB.

1. Single-Sided FPC: The lowest cost printed circuit board that do not require high electrical performance. In Single-Sided FPC Layout, it has a layer of chemically etched conductive patterns, and the conductive pattern layer on the surface of the flexible insulating substrate is a rolled copper foil. The insulating substrate can be polyimide, polyethylene terephthalate, aramid cellulose ester and polyvinyl chloride.

2. The Double-Sided FPC: A conductive pattern made by etching on both sides of the insulating base film. The metallized hole connects the patterns on both sides of the insulating material to form a conductive path to meet the design and use function of flexibility. The coverlay can protect single and double-sided traces and indicate where the components are placed.

3. Multiayer Flex PCB: To laminate 3 or more layers of single-sided or double-sided FPC together, and form metallized holes by drilling and electroplating to form conductive paths between different layers. In this way, no complicated soldering process is required. Multilayer circuits have huge functional differences in terms of higher reliability, better thermal conductivity and more convenient assembly performance. When designing the layout, the mutual influence of assembly size, number of layers and flexibility should be considered.

4. The traditional Rigid-Flex PCB: Be composed of rigid and flexible substrates selectively laminated together. The structure is tight, and the metallized hole L forms a conductive connection. If a printed board has components on the front and back sides, rigid flexible circuit boards are a good choice.But if all the components are on one side, it will be more economical to choose a double-sided flexible circuit board and laminate a layer of FR4 reinforced material on its back.

5. The FPC flex circuit board with hybrid structure is a multi-layer board, and the conductive layer is made of different metals. An 8-layer board uses FR-4 as the inner layer medium and polyimide as the outer layer medium. Leads extend from three different directions of the main board, and each lead is made of a different metal. Constantan alloy, copper and gold are used as independent leads. This kind of hybrid structure is mostly used in the relationship between electrical signal conversion and heat conversion and under low temperature conditions where the electrical performance is relatively harsh. It is the only feasible solution. It can be evaluated by the convenience of the internal connection design and the total cost to achieve the best performance-price ratio.

For two sided board, using through hole within the middle connects two-sided traces, and there are 2 more processes than single aspect board, that is Electroless Copper and plating.

Double sided boards are wide used and relatively easy, each manufacturer can do, that the competition is usually on the price.

Some makers use low grade CCL, soldermask ink is also comparatively low cost, even the surface plating is skinny, leading to price variations.

At Rocket PCB, we have been using top-grade materials, never cut corners, quality is first-class, our strategy is tiny profits but fast turnover, therefore within the premise of quality assurance, our PCB price is extremely competitive, you’re welcome to inquiry here to get quick quotation!

Common Types of Flexible Circuit Board ( FPC )

At present, FPC basically includes four types: Single-sided FPC, Double-sided FPC, Multilayer FPC and Rigid-flex FPC;

Single-sided FPC

Single-sided FPC is the lowest cost printed circuit board that do not require high electrical performance. For single-sided wiring, a single-sided flexible circuit board should be used. It has a layer of chemically etched conductive patterns, and the conductive pattern layer on the surface of the flexible insulating substrate is a rolled copper foil. The insulating substrate can be polyimide, polyethylene terephthalate, aramid cellulose ester and polyvinyl chloride.

Double-sided FPC

The double-sided FPC is a conductive pattern made by etching on both sides of the insulating base film. The metallized hole connects the patterns on both sides of the insulating material to form a conductive path to meet the design and use function of flexibility. The cover film can protect single and double-sided traces and indicate where the components are placed.

Multilayer FPC

Multi-layer FPC is to laminate 3 or more layers of single-sided or double-sided FPC flexible circuit boards together, and form metallized holes by drilling and electroplating to form conductive paths between different layers. In this way, there is no need to use a complicated welding process. Multilayer circuits have huge functional differences in terms of higher reliability, better thermal conductivity and more convenient assembly performance. When designing the layout, the mutual influence of assembly size, number of layers and flexibility should be considered.

Rigid-flex FPC

The traditional rigid-flex circuit board is composed of rigid and flexible substrates selectively laminated together. The structure is compact, and the metallization hole L forms a conductive connection. If there are components on the front and back of a printed circuit board, a rigid flexible circuit board is a good choice. But if all the components are on one side, it will be more economical to choose a double-sided flexible circuit board and laminate a layer of FR4 reinforced material on its back.

The FPC flexible circuit board with hybrid structure is a multi-layer board, and the conductive layer is composed of different metals. An 8-layer board uses FR-4 as the inner layer medium and polyimide as the outer layer medium. Leads extend from three different directions of the main board, and each lead is made of a different metal. Constantan alloy, copper and gold are used as independent leads. This kind of hybrid structure is mostly used in the low temperature conditions where the relationship between electrical signal conversion and heat conversion and the electrical performance are relatively harsh, and it is the only feasible solution. It can be evaluated by the convenience of the internal connection design and the total cost to achieve the best performance-price ratio.
