Industrial PCB By Feature

Single-Sided Industrial PCB

Our Single-sided Industrial PCB is the perfect solution for electronic assemblies and all general applications where electronic components are on one side of the board.

Double-Sided Industrial PCB

These boards are very useful in many electronic products as the circuits on one side of the board can be connected to the other with the help of holes drilled onto the board.

Multilayer Industrial PCB

Common to all multilayer Industrial PCB’s is the use of 2 (or more) layers of copper interconnect plating. The layer count goes up from there: the more interconnects the better!

Rigid Industrial PCB

Inflexible in their structure and therefore cannot be bent or flexed. Used in applications where quality is an asset, e.g. where the product needs to be stable, safe, and static.

Flex Industrial PCB

Its patterned arrangement of printed circuitry and components utilizes a flexible substrate made with a flexible or semi-flexible material as an outer coverlay.

Rigid Flex Industrial PCB

Rigid-Flex Industrial PCB has excellent performance and its flexibility can be bent to any desired angle. Offers optimum solutions for difficult, limited space conditions.

Industrial PCB – The Completed FAQ Guide

The Industrial PCB is one of the most common types of electronic components, and the most common question when considering this type of PCB is: what exactly is it? The answer depends on what you want to accomplish with your PCBs. Its copper layers are protected by a layer of resist. Unlike copper foil or full-on copper coating, the resist is not applied to all copper areas. The reason for this is simple: copper conducts electrical signals, much like nerves conduct messages between the brain and muscles.

4-Layer Industrial PCB

4-Layer Industrial PCB

What Are the Composition of Industrial PCBs?

PCB materials vary, and the choice is dictated by the application’s requirements. Different materials have various properties. Materials are typically selected by circuit designers based on their electrical performance, thermal resistance, or compliance with government regulations.

The European Union, for example, prohibits the use of certain chemicals and metals under the Restriction of Hazardous Substances (RoHS) directive. Consider the following factors when selecting a PCB substrate.

How Many Types of Industrial PCBs Are There?

If you’re wondering, you’re not alone. There are numerous types, including flexible, rigid, and hybrid. Learn more about each type in the sections below. If you want to make your own circuit board, you should look for a PCB that comes in a variety of thicknesses. This way, you can ensure that your new board fits perfectly and will function properly in your equipment.

Multiple layers of copper are used in multilayer PCBs. These layers expand the area available for wiring. Multilayer PCBs are commonly used in larger, more complex devices such as smartphones. Single-layer PCBs, on the other hand, is extremely simple. These boards are found in almost all devices, including mobile devices. The number of layers used varies depending on the application, but the overall layout of a circuit board is determined by its complexity.

Multilayer Industrial PCB

Multilayer Industrial PCB

Single-sided PCBs are the most common and cost-effective type of board. They are made of a single layer of conductive material, usually copper. The board is then covered with a solder mask for protection. The final screen printing will identify all of the elements on the board. Single-sided PCBs are very simple to produce. The disadvantage of single-sided PCBs is their high cost. However, these boards are popular because they are inexpensive.

Prepreg is an epoxy-impregnated pre-resin. It’s sandwiched between a core and copper foil. The epoxy then sets, bonding the copper foil to the core and copper sheeting. The enclosure of the board determines the thickness of the traces. The boards are subjected to heat and pressure during this step. The end result is a high-quality circuit board.

Rigid PCBs are used for devices or applications that require a high degree of flexibility. This type of board is rigid, which means it will not bend. Flexible PCBs are used in consumer electronics such as computer keyboards. Rigid-flex PCBs are constructed with multiple layers of rigid circuits. They can be single-sided, double-sided, or multi-layered. Both types of PCBs are available in a variety of shapes and can be customized to fit any shape or dimension. Rigid PCBs are also used in military weapons, aerospace systems, and cell phones.

The copper thickness of PCBs varies. Most PCBs have a copper thickness of one ounce per square foot. Thick copper layers are used for higher power loads. They are typically thinner than thin copper. A single ounce per square foot sheet of copper contains approximately 34 micrometers. This is referred to as heavy copper. The metal-core layer is used in applications that require high current or heat dissipation.

Typical multilayer boards are made of copper, glass, or FR-4. Copper-clad laminates, or PCBs with etched copper on the surface, require an insulating layer. Inhomogeneities can occur when the dielectric constant decreases with frequency. Inhomogeneities can also occur with decreasing board features and increasing frequencies. A typical circuit board substrate is made of a dielectric composite material with an epoxy resin matrix and reinforcement layers made of woven or nonwoven glass fibers. Titanate ceramics are another material used to increase the dielectric constant.

What Are the Best Materials for Industrial PCB?

Industrial PCBs are made from a variety of materials. Polycarbonate is the most common type of PCB. It is a lightweight, flame-resistant polymer made of woven fiberglass cloth. The outer layers of the PCB are protected by soldermask. Another important material is the nomenclature, which is a silkscreen that clearly shows component placement and orientation.

An industrial PCB’s material must provide excellent heat transfer and dissipation, improve signal performance, and have a low Df. High-speed circuits necessitate tight impedance control and a low Df. Chemicals, moisture, and temperature can all affect the electrical performance of industrial PCBs. A high-quality industrial PCB can also accommodate future hardware upgrades.

Industrial PCB Materials

Industrial PCB Materials

Flexible PCBs are also available in a variety of materials. PEEK, polyimide, and copper are a few examples of flexible materials. These materials are often more expensive, but they are better for high-frequency use. Flex-rigid PCBs are frequently made from multiple layers of flexible PCB and are adhesive-free. Flexible boards are frequently used in medical and aerospace applications. These circuit boards can withstand high temperatures depending on their function.

A high-quality board should be flame-resistant. A UL rating is important for many electronics because it indicates that a circuit board will self-extinguish if it catches fire. Laminates are typically made from cloth fabric and resins. Each laminate has advantages and disadvantages. Some are FR4 epoxy and Teflon, while others are glass-resin composite. Thermal factors will ultimately determine which type of laminate is best for your PCB design.

What Is the Industrial PCB Manufacturing Process?

The industrial PCB manufacturing process entails producing a large panel of circuit boards with a thickness of 0.062″ or less. The process begins with the application of a copper-clad FR4 core material known as “prepreg,” or “B-stage” fiberglass. The prepreg is flexible until heated, at which point copper layers are bonded to the copper foil. Following that, the PCB is assembled and tested to ensure that it functions as intended.

PCB Drilling Process

PCB Drilling Process

After the engineering work is completed, photo plotting begins. AOI, or automated optical inspection, is used to check the board for errors before the lamination process begins. The AOI equipment compares the board to the Gerber file design to ensure that no layers are defective. The board is laminated after the design has been validated. The outer PCB surface is made of fiberglass pieces that have been pre-soaked in epoxy resin. Inner PCB parts are made of thin copper foil with copper trace etching. The outer and inner layers are joined together.

A PCB planner goes over the design data after each step. They create a process card that specifies the manufacturing steps, quantity, and delivery date. The planner then goes over all of the project’s information to ensure that all of the necessary materials are on hand. After reviewing all of the details, the PCB planner will create a Process Card that accurately represents the production process. The Process Card will include a barcode for easy tracking.

What Are the Industrial PCB Applications?

There are numerous PCB applications in industrial settings. They can be found in everything from portable printers to welding machines. Other applications include safety and security devices, mining instruments, power supply units, and solar panels. They can even be found in utility meters.
