Rigid PCB – The Completed FAQ Guide

This comprehensive guide covers the basics of rigid circuit boards and what makes them so attractive to the design industry. Among its advantages are ease of manufacture and quick turnaround. The rigid PCB features a layer of dielectric between two metal layers. Its simplicity is also apparent in its reduced space usage.

A rigid PCB is also easy to repair or assemble. If you’re new to PCB design, this comprehensive guide will help you to get up to speed quickly.

What is Rigid PCB?

It is essentially a rigid printed circuit board. The substrate is the primary distinction between flexible and rigid PCBs. Flexible PCBs can bend and turn without causing damage to the circuits. A flex circuit board is attached to a rigid circuit board on some rigid-flex boards.

These are extremely useful for compound design requests because they can meet the requirements of both flexible and rigid PCBs.

A typical rigid PCB has two layers, one of which is the substrate (FR4). A solder mask protects the copper layer, and the dielectric layer is a silkscreen representation of the various components.

They are also thinner than FR4 counterparts, reducing board weight and increasing circuit density. Because of these benefits, they are ideal for small, lightweight devices. Continue reading if you’re wondering, “What is rigid PCB?”

Rigid PCB

Rigid PCB

Rigid boards are ideal for applications that require a high level of stability. They are less expensive and have fewer parts than flexible PCB boards. They can also be used for items that require weight. There are numerous advantages to rigid PCBs over flexible boards.

Although these boards are extremely useful in electronic devices, they are not always the best option for every project. They are not, however, as adaptable as their more flexible counterparts. Furthermore, they may raise the overall cost of the board.

Manufacturing flexible PCBs is costly. They are a good choice for small-size, compact designs because they are less expensive to produce.

They also provide improved connections to other circuit boards, electronic components, and the user interface. They are also lighter, so they take up less space. So, if you need a low-cost, high-quality rigid PCB, look for a manufacturer with a wide range of design and layup options.

What Are the Different Types of Rigid PCBs?

Rigid PCBs are commonly used in desktop and handheld electronics. They can be found in GPS equipment, computer motherboards, and mobile phones, for example. They are, however, used in medical equipment such as X-rays, heart monitors, CAT scans, and MRI systems. They are also used in temperature sensors and control tower instrumentation. Here’s a closer look at some of the most common rigid PCB types.

They are made up of several layers. The substrate layer, or base material, comes first. This layer is typically made of FR4 fiberglass. It gives the board a rigid feel while also being less expensive than other materials. Some designs employ FR1 or FR2, while ultra-low-cost models employ FR3.

They have different thermal, electrical, and heat resistance properties, despite their lower cost. This is due to the fact that the materials have different physical properties, which can cause manufacturing and quality control issues.

Rigid printed circuit boards are the most common type of printed circuit board. They are made of solid substrate materials, which prevents twisting. A computer motherboard, for example, is made up of many layers and is made up of a rigid PCB.

Multilayer Rigid PCB

Multilayer Rigid PCB

There’re many types of rigid PCBs:

Rigid PCBs are commonly used in desktop products and are a less expensive option for some electronics. They are frequently used in audio keyboards, audio players, solid-state drives, flat-screen TVs, monitors, and toys, for example. Because they are so tough, they are ideal for applications requiring part attachment and high-temperature performance. However, rigid PCBs are superior in low-cost electronics.

What Is the Difference Between Rigid and Flexible PCBs?

The primary distinction between rigid and flexible boards is the substrate material used. The boards are made with a flexible dielectric film and glue film. Polyester, polyimide, and fluoropolymer are all common materials.

The copper weight used in rigid-flex PCBs varies. This article discusses the advantages and disadvantages of both materials. Learn the distinctions between rigid and flexible PCBs and which is best for your project.

The rigid and flexible circuit board fabrication processes differ from one another. Rigid boards typically have 20 or fewer layers, whereas flexible boards have more layers. Mechanical properties differ depending on the layer.

Rigid and flexible boards, on the other hand, have similar material layup and thickness. In general, rigid boards are less expensive and easier to work with. The following are the primary advantages of flexible PCBs:

Consider the intended use of your PCB when selecting the right type for your project. Are you creating a PCB for a video game console? Or are you creating an electronic device for your home? Rigid-flex PCBs have thin profiles and are ideal for ultra-light bundling.

They also have dynamic flexing copper layers. Rigid-flex PCBs are often preferable for ultra-light electronics, but they are not required for all applications.

Rigid-flex PCBs may be less expensive for IC manufacturers, but they have other drawbacks. Rigid-flex PCBs are frequently fragile, with the adhesive layer cracking when bent. RA copper is more malleable, whereas ED copper is almost exclusively used for rigid PCBs. Rigid-flex PCBs are frequently less expensive to manufacture, but they require less quality control.

Let’s take a closer look at the various options to answer the question, “What is the Surface Finish on a Rigid PCB?” Each surface finish has benefits and drawbacks. It is critical to understand these options in order to make the best decision for your design.

PCB manufacturers can help you understand the differences between these options. Some of the most common surface finishes are listed below.

  • Hot Air Solder Level (HASL)
  • Lead-Free HASL
  • Organic Solderability Preservative (OSP)
  • Immersion Silver (Au)
  • Immersion Tin (Sn)
  • Electroless Nickel Immersion Gold (ENIG)
  • Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG)
  • Electrolytic Wire Bondable Gold
  • Hard Gold

When selecting a surface finish, it is critical to consider the product’s reliability requirements. Lead-free solder complies with RoHS regulations, but it is more prone to contamination and breakage when handled. It can also be wire bonded and used in ball grid arrays and tight-pitch components. It has a longer shelf life as well, but may not be as suitable for contact applications.

Another type of surface finish is ENEPIG. It’s a type of electroless nickel immersion gold, also known as ENIG. This finish is pricey but meets RoHS requirements. Its three layers protect the copper from oxidation, and the gold layer prevents the formation of black pads.

As a result, the ENIG surface finish is more expensive than the ENIG surface finish. ENIG follows the RoHS guidelines in addition to being copper resistant.

ENIG metallization produces a high-quality surface finish but has a lower aesthetic value than OSP and HASL. It is, however, still suitable for low-pitch and low-frequency server boards.

The high-temperature bath, on the other hand, has the potential to warp the surface. So, how should you go about selecting a Surface Finish for your Rigid PCB?

What Are the Applications of Rigid PCB?

The copper layer, the substrate layer, and the solder mask are the double layer of a rigid printed circuit board. These layers shield the copper layer and represent various components. After that, these layers are laminated on top of each other.

Finally, the rigid PCB is a fully functional electronic device. Computers, laptops, portable devices, and other electronic devices are common uses for rigid PCBs. Some of these applications are discussed in this article.

To save lives, the medical industry relies on cutting-edge electronic technology and circuitry. Medical devices are manufactured by companies dedicated to improving the world’s health, ranging from portable PDA-like devices used to track packages to a variety of military and aerospace applications. As medical devices become more sophisticated and compact, their circuitry must keep up.

Flexible PCBs are an excellent choice for these harsh environments. They can withstand harsh conditions without compromising performance.

Another common application for rigid PCB is in industrial equipment. These are frequently large, immobile machines. They can be made of copper, aluminum, or other high-temperature-resistant materials.

High-temperature laminates can also be used to protect the circuit boards from environmental contaminants. Rigid printed circuit boards are also used in the aerospace industry. Because these boards can withstand high temperatures, they are ideal for use in aerospace.

Rigid-flex circuit boards are used in a variety of industrial applications in addition to portable electronics. They combine the benefits of rigid and flexible circuits, allowing for greater component density, lower packaging weight, and improved reliability. Flex circuit boards are a good solution for these problems, especially with the increased demand for lightweight electronics.

They also provide more manufacturing flexibility, which is useful in some situations. These materials are widely used in portable electronics, which is not surprising.

How to Choose a Professional Rigid PCB Supplier?

When it comes to PCB manufacturing, rigid circuit boards are the most common. They’ve been around for a while, but they’re still very popular today.

Rigid circuit boards, as opposed to flexible PCBs, are solid and cannot be bent or flexed. Heat or adhesive is used to join the layers. They can be single- or double-sided, as well as multi-layered. The disadvantage of rigid PCBs is that they cannot be changed or modified once manufactured.

Rigid-flex PCBs cost more than their flexible counterparts. This is because they use specialized materials for the impedance layers, such as no flow prepreg, adhesiveness flexible laminates, and thicker flex dielectrics.

Rigid-flex PCBs are more complex and time-consuming to manufacture than flexible PCBs. However, their attention to detail and high quality make them well worth the extra cost.

Consider the following factors when looking for a good supplier. The supplier’s ability to model impedance is an important consideration. Check that they have impedance modeling software. The dielectric value supplied by the material manufacturer, which may be inaccurate, can be used in free modeling software.

If this isn’t an issue, your rigid PCB manufacturer should have no trouble handling the project.

Rigid-flex PCBs are designed using specialized equipment and software by experienced PCB manufacturers. They should be well-versed in the subject matter and have access to all necessary resources. Printed Circuits recommends a rigid-flex PCB manufacturer with extensive experience.
