What is Solder Resist? Solder Resist Material

Wednesday, February 19th, 2025

Solder resist is a key material used in PCB (Printed Circuit Board) manufacturing to protect the circuit traces. This thin layer, typically green in color, ensures that solder only adheres to specific areas during the assembly process. Without solder resist, PCBs could suffer from short circuits, poor connections, and overall performance issues.

What is a Solder Resist?

Solder resist, sometimes known as a solder mask, is a protective layer applied to the surface of a PCB. In essence, solder resist is an insulation ink, its primary function is to prevent the solder from flowing onto unwanted areas during the soldering process. By applying a layer of solder resist, manufacturers can ensure the quality and reliability of the board’s electrical connections.

The solder resist material protects the copper traces, ensuring that the PCB functions correctly by providing an insulated surface. It also enhances the overall durability of the PCB by preventing oxidation or damage to the copper.

Types of Solder Resist

There are several types of solder resist materials, each offering different benefits for specific manufacturing processes. Each type of solder resist serves its purpose based on the complexity of the PCB design and the manufacturing process involved. The most commonly used solder resist types are:

Liquid Solder Resist: Applied using a spray or traditional screen printing method, this type is the most popular and offers ease of application. In generally, it is a default types of soler resist if there are no any special requirements from customers.
Dry Film Solder Resist: This is a laminated material that is applied to the board before exposure to ultraviolet (UV) light. After exposure, the unwanted parts of the resist are washed away.
Photo-sensitive Solder Resist: It is a special variant that reacts to UV light, making it ideal for highly detailed, small-scale PCB designs.

Photos of Solder Resist

While solder resist is typically green, variations exist depending on the design and function of the PCB. Photosensitive solder resist, for example, is often used in more intricate PCB designs because it allows for precise control of where the resist material is applied. Below are some examples of PCBs showcasing different types of solder resist and their impact on the circuit layout.

What Does Solder Resist Do?

Solder resist plays several critical roles in PCB manufacturing:

1. Prevents Short Circuits

One of the key roles of solder resist is to prevent solder from adhering to areas other than the intended electrical contacts on a printed circuit board (PCB). During the soldering process, it ensures that solder only sticks to the pads where components are placed. By blocking solder from unwanted areas, it ensures that electrical connections are not unintentionally bridged.

2. Protecting Circuit Patterns from Dust, Heat, and Moisture

Solder resist acts as a protective shield, safeguarding the delicate circuit patterns from external factors like dust, heat, and moisture. These environmental conditions can otherwise compromise the performance and longevity of the PCB.

3. Supports Manufacturing / Smooth Manufacturing Process

A layer of solder resist guides the soldering process by clearly defining where the solder should go, smooth the whole process, making the entire assembly process more efficient.

4. Maintaining Electrical Insulation Between Circuit Patterns

As electronic devices become smaller and more complex, the circuit patterns on PCBs have shrunk significantly, 50 to 150 µm dimensions are always commonly used in the market. And even thinner on advanced package boards. Solder resist ensures that these circuit patterns remain electrically insulated from one another, preventing accidental short circuits.

Solder Resist Material

Solder resist materials vary based on the requirements of the PCB and the intended application. The most common materials used include:

Epoxy-based resists: These are widely used due to their excellent adhesion and resistance to high temperatures and chemicals.
Acrylic-based resists: Known for their fast curing times and easier handling, they are suitable for mass production.
Polyimide-based resists: Used for high-performance applications, especially in extreme environments.

The material selected depends on factors such as the desired performance, operating environment, and manufacturing capabilities. Each material has its advantages and is chosen according to the specific requirements of the PCB design.

What is the Thickness of Solder Resist?

The thickness of solder resist plays an important role in the overall performance of the PCB. Typically, the solder resist layer has a thickness between 15 and 30 microns (0.5mil to 1.2mil). The solder mask tends to be thinner near the edges of the traces and can be as thin as 0.3 mils or even less.

Typically, it’s recommended to have around 0.5 mils of solder mask covering the traces. This thickness ensures optimal protection without interfering with the soldering process or compromising the performance of the circuit. The exact thickness may vary depending on the complexity of the PCB design, but in general, it is thick enough to protect the copper traces while being thin enough to not interfere with the components’ performance. If you can’t make a decision about the solder resist thickness, it is a good way to ask a trust PCB manufacturer to get your answer, such as Best Technology.

Solder Resist vs. Solder Mask

Many people are confused about solder mask and solder resist: “Are they same or what are the differences between them?”

Actually, the terms solder resist and solder mask are essentially referring to the same concept. Both terms describe the protective layer applied to PCBs to prevent solder from bridging unwanted areas. While “solder mask” is commonly used, “solder resist” is more technically accurate since the resist material resists the solder during the assembly process. However, both terms are widely interchangeable in the industry.

Solder Resist Colors

While green is the most widely recognized color for solder resist, it’s far from the only option available. Solder resist can be found in a variety of colors, including red, blue, black, yellow, and even white, depending on the requirements of the PCB design or the specific application where this PCB will be used. These color variations serve different purposes, ranging from aesthetic preferences to functional considerations.

For example, some high-end or custom-designed PCBs may use colors like black or blue to create a distinct visual identity or to align with branding guidelines. In industries like aerospace or medical devices, where high-performance and unique design are often crucial, color may also be chosen for its visibility during the manufacturing process or in final product assembly.

However, the color choice isn’t only about appearance. In some cases, it can help with thermal conductivity, which can be important for applications that involve high-power circuits. Additionally, certain colors are more reflective under UV light, which aids in the photolithographic process. For example, blue solder resist can be beneficial for high-resolution applications, as it tends to make the ultraviolet light exposure process more precise. We’ve introduced the detailed functions about PCB colors in our other blogs:

Why is Solder Resist Green?

While various colors of solder resist exist, green has become the industry standard for a variety of reasons, many of which are practical rather than just aesthetic.

High Contrast and Visibility

One of the main reasons for the green color’s dominance is its high visibility, especially under ultraviolet (UV) light. During the PCB manufacturing process, photolithography is used to expose specific areas of the board to UV light. Green solder resist is highly visible under UV, so FQC (final quality check) inspectors can inspect the board for defects or imperfections in the soldering process.

Optimal Performance in Photolithography

The process of applying solder resist involves exposing the board to UV light, which causes the resist material to harden in specific patterns. Green solder resist material is particularly well-suited to this process, as it is engineered to react efficiently to UV exposure.

Cost-Effectiveness and Standardization

Another reason green solder resist is so commonly used is its cost-effectiveness. Green has become the default color because it is the most widely produced, and cost effective. Standardizing on green also simplifies production processes, as manufacturers can keep a consistent stock of the same type of material.

Historical Tradition

The history of green solder resist dates back to the early days of PCB manufacturing. Green was originally chosen due to its availability, as it was one of the first colors of solder resist to be mass-produced. Over time, this color became synonymous with PCBs, and manufacturers continued to use it because it had already proven reliable and effective.

Visual Appeal

Finally, there’s a practical and visual appeal to the green color. Green provides a clean, professional look for most PCBs and offers a neutral backdrop that allows the components and circuitry to stand out clearly. This is important, especially for high-precision and high-performance boards that need to be easily inspected for quality.

Non-Flex Cut vs Flex Cut PCB: What Is Flex Cut PCB?

Tuesday, February 18th, 2025

The debate of non-flex cut vs flex cut PCB has been a common topic for engineers and manufacturers. When designing printed circuit boards (PCBs), one key decision is whether to use a flex cut or non-flex cut PCB. These two types of PCBs serve different purposes, with unique advantages depending on the application. But how do they differ, and when should you use each? This guide will dive into the specifics, providing you with insights to make an informed decision.

What is a Flex Cut PCB?

A flex cut PCB is a type of printed circuit board that’s designed to be flexible. Unlike traditional rigid PCBs, flex PCBs can bend and flex without compromising the performance of the electrical circuits. This flexibility is achieved by using materials such as polyimide, which allows the board to conform to various shapes and spaces.

Flex cut PCBs are commonly used in devices where space is limited or for designs that require a dynamic or compact setup, such as in wearable tech or mobile phones. Their flexible nature provides the freedom to design intricate layouts without being restricted by rigid geometries.

What is the Difference Between Flex Cut and Non-Flex Cut PCB?

The main difference between flex cut and non-flex cut PCBs lies in their physical structure and flexibility. As mentioned, flex cut PCBs are made from flexible materials, which means they can be bent, twisted, or folded. This flexibility makes them suitable for applications where space constraints are a concern, and the board needs to fit into non-traditional forms or be more compact.

In contrast, non-flex cut PCBs, often referred to as rigid PCBs, are built using rigid substrates like FR4 or aluminum, providing stability and durability. These boards do not bend and are generally used in devices that do not require flexibility.

Both types of PCBs have their unique advantages. Flex cut PCBs are best for space-saving and adaptability, while non-flex cut PCBs are ideal for products that need more stability and rigidity.

Why Use a Flex PCB?

There are several reasons to opt for a flex PCB in certain applications. One of the biggest advantages is its ability to save space. Flex PCBs can be folded or shaped to fit into areas where rigid PCBs cannot. This makes them an excellent choice for compact electronic devices such as smartphones, cameras, and medical equipment.

Additionally, the flexibility allows for more robust designs in environments with high mechanical stress, such as robotics or wearables. Flex PCBs can withstand vibration and movement better than rigid boards, offering better durability in these conditions.

Finally, the lightweight nature of flex PCBs contributes to the overall efficiency of the product, making them an essential component in modern, miniaturized electronics.

What is an FR4 Plate?

FR4 is a widely used material in the manufacturing of rigid PCBs. It stands for “Flame Retardant 4” and is a type of fiberglass epoxy laminate. The FR4 material provides excellent strength, low moisture absorption, and good electrical insulation properties.

While FR4 is typically used for non-flex cut PCBs, it can also be used in multi-layer flexible PCBs in certain designs. Its role is to provide stability and electrical insulation, making it a crucial material in traditional PCBs.

What is Tri-Mode Non-Flex Cut Hotswap PCB?

Tri-mode non-flex cut hotswap PCBs are a specialized type of PCB designed for mechanical keyboards, offering a flexible, user-friendly experience. The term “tri-mode” refers to the ability to support multiple connection types, such as wired, Bluetooth, and wireless.

The non-flex cut hotswap design enables users to easily replace or swap out switches on the keyboard without the need for soldering. This makes it ideal for enthusiasts who want to customize their keyboards with different types of switches. It combines the advantages of non-flex cut rigidity with the versatility of hotswapping.

What is a Rigid-Flex PCB?

A rigid-flex PCB is a hybrid of both rigid and flexible PCB technologies. It consists of both rigid and flexible sections integrated into a single board. These PCBs offer the best of both worlds, combining the stability and reliability of rigid PCBs with the flexibility of flex PCBs.

Rigid-flex PCBs are often used in high-performance applications such as aerospace, medical devices, and automotive systems. They provide a compact solution where multiple PCB types need to coexist, and their flexible sections can be bent or folded to fit complex spaces.

What Are the Disadvantages of Rigid-Flex PCBs?

Despite their advantages, rigid-flex PCBs come with some drawbacks. One major disadvantage is their cost. Due to the complexity of manufacturing, rigid-flex PCBs tend to be more expensive than traditional rigid or flex PCBs.

Additionally, the design and production process for rigid-flex PCBs is more intricate, requiring higher precision and more time. This can also lead to longer lead times for production, which may not always be ideal for projects with tight deadlines.

When Should I Use a Flex PCB?

Flex PCBs are perfect for applications where flexibility, compact design, and space-saving are important. You should use a flex PCB when your product needs to fit into tight or unique spaces, like wearable devices, medical equipment, or consumer electronics.

They are also a good choice for products that need to endure repetitive movement or vibrations. In situations where the PCB needs to be bent or folded without breaking, such as in robotics or automotive designs, flex PCBs offer exceptional reliability.

Are Flexible PCBs More Expensive?

Flexible PCBs generally come at a higher cost compared to non-flex cut PCBs. This is due to the specialized materials and the intricate manufacturing process required for flexible designs.

However, despite the initial cost increase, flex PCBs can provide long-term cost savings by reducing the overall size of the device and minimizing the need for additional components or connectors. For applications where space is crucial or where traditional PCB designs would be too bulky, the investment in a flex PCB can pay off in the long run.

In the debate of non-flex cut vs flex cut PCB, the right choice ultimately depends on the needs of your project. Flex PCBs excel in compactness and flexibility, making them a great choice for dynamic, space-constrained designs. On the other hand, non-flex cut PCBs offer superior stability and durability for applications where rigidity is key.

For some projects, you might even find that combining the benefits of both technologies, like in rigid-flex PCBs, offers the perfect balance of performance and flexibility. When making your decision, consider the design requirements, budget, and long-term needs of your application.

1.6t vs 1.2 PCB: Why are PCBs 1.6 mm thick?

Tuesday, February 18th, 2025

The debate between 1.6t vs 1.2 PCB is a common one for those designing or customizing mechanical keyboards. The thickness of a PCB affects not only the overall durability but also the typing experience. Whether you prioritize a solid feel with a 1.6 mm PCB or prefer the lighter, more flexible nature of a 1.2 mm PCB, understanding these differences can help you make the right choice. In this blog, we’ll break down the key distinctions, and show you how the thickness of your PCB can influence the performance and comfort of your keyboard.

What is the difference between 1.2 and 1.6 PCB?

The primary difference between a 1.2 PCB and a 1.6 PCB is the thickness of the board itself. A 1.2 PCB is 1.2 millimeters thick, while a 1.6 PCB measures 1.6 millimeters. The thickness of a PCB impacts its durability, rigidity, and overall feel in applications such as mechanical keyboards.

A 1.2 mm PCB is often used in keyboards that require a more flexible, lighter feel. It’s commonly chosen for lightweight builds or when aiming for a slim profile. On the other hand, a 1.6 mm PCB is thicker, providing greater rigidity, which results in a more solid, firm keypress experience. This thickness is favored in high-end mechanical keyboards, where stability and a more premium feel are prioritized.

Why are PCBs 1.6 mm thick?

PCBs are typically 1.6 mm thick because this thickness offers an excellent balance between durability and flexibility for most applications. At 1.6 mm, the board is sturdy enough to support complex circuit designs and ensure reliable performance, yet it remains thin enough to fit comfortably within most electronic devices, including keyboards.

The 1.6 mm thickness is the industry standard for many consumer electronics, as it can accommodate a variety of components without compromising the integrity of the circuit. It’s also an ideal thickness for creating a uniform look in keyboards, ensuring that all components fit together neatly while still maintaining high-quality performance.

What is the thickness tolerance of a 1.6 mm PCB?

The thickness tolerance of a 1.6 mm PCB generally falls within a range of ±0.1 mm. This means that the actual thickness of the PCB can vary slightly, typically between 1.5 mm and 1.7 mm, depending on the manufacturing process. Tolerance is an important factor because even slight variations in thickness can affect the fitting and performance of components, especially in high-precision builds like mechanical keyboards.

However, manufacturers ensure that the tolerance level is within an acceptable range to prevent any significant issues when assembling the keyboard. This makes it easier to work with PCBs of this thickness, as the components are more likely to fit correctly and perform optimally.

What is the most common PCB thickness?

The most common PCB thickness is 1.6 mm, particularly for consumer electronics, including keyboards, smartphones, and other portable devices. This thickness strikes the perfect balance between strength and flexibility, making it the default choice for many applications. Whether you are designing a simple circuit or a more advanced mechanical keyboard, the 1.6 mm PCB provides the reliability and durability needed for long-term use.

In keyboards, this thickness is widely used for both standard and custom builds. It’s not too thin to compromise the keyboard’s structure, and it’s not so thick that it adds unnecessary bulk.

What is the minimum thickness of a PCB?

The minimum thickness of a PCB depends on several factors, including the materials used, the intended application, and the manufacturing process. Typically, the thinnest PCB available is around 0.2 mm, though PCBs thinner than this can become fragile and less durable.

For practical applications like keyboards, it’s rare to see PCBs thinner than 1.2 mm, as they may struggle to support the components required for stable keypresses. A thinner PCB can result in a less solid typing experience, which is why manufacturers typically avoid using extremely thin PCBs for high-performance builds.

What is the thinnest PCB material?

The thinnest PCB materials are typically made from flexible substrates, such as polyimide or polyester films. These materials allow for extremely thin designs that can be as low as 0.2 mm. These ultra-thin PCBs are often used in applications where space is limited, such as in wearable electronics or medical devices.

However, it’s important to note that these thin materials often sacrifice some rigidity and may not be suitable for all types of keyboards. While they work well for compact or flexible designs, a more rigid PCB like the 1.2 mm or 1.6 mm versions is usually preferred in mechanical keyboards for their stability and performance.

Does PCB thickness matter?

Yes, PCB thickness does matter, especially when designing keyboards or other precision electronics. The thickness of the PCB affects the overall rigidity, weight, and feel of the final product. In a keyboard, for example, a thicker PCB (like the 1.6 mm version) will create a sturdier, more solid feel with less flex during typing.

Thicker PCBs are often preferred in mechanical keyboards because they provide a more premium typing experience and reduce the likelihood of issues such as warping or bending. On the other hand, thinner PCBs (such as the 1.2 mm version) offer a lighter and more flexible feel, making them suitable for custom builds or portable devices where weight and space are critical considerations.

Are PCB switches hot swappable?

Hot-swappable PCB switches allow users to change switches without soldering. Many mechanical keyboards now feature hot-swappable PCBs, providing the flexibility to try different switches or replace worn-out ones with ease.

However, not all PCBs are hot-swappable. A PCB must be designed specifically with hot-swapping functionality in mind, meaning that the PCB must have switch sockets and a proper electrical layout to support this feature. Many high-end 1.6 mm PCBs include this option, while thinner or cheaper PCBs might not.

In summary, the choice between 1.6t vs 1.2 PCB comes down to the specific needs of your project. While the 1.6 mm PCB offers greater rigidity and durability, the 1.2 mm PCB provides a lighter and more flexible option. For keyboards, both thicknesses have their merits, depending on whether you’re looking for a more solid typing experience or a sleeker, more portable design.

When selecting a PCB thickness, it’s essential to consider not only the thickness itself but also the application and overall design goals. Whether you’re building a custom keyboard or upgrading an existing one, understanding these PCB variations will ensure that you choose the right components for your needs.

By opting for the right PCB thickness and features like hot-swappable switches, you can enhance your keyboard’s functionality and enjoy a superior typing experience.
