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.

How to Prevent Blackening During AlN Laser Cutting?
Monday, January 27th, 2025

Blackening during AlN laser cutting is a challenge that many engineers and manufacturers face when working with aluminum nitride (AlN) materials. This discoloration can affect both the appearance and performance of the final product, making it crucial to understand the causes and methods to prevent it. In this article, we will explore what AlN laser cutting involves, where it’s commonly used, and the various factors that contribute to blackening. We’ll also offer practical tips for reducing blackening and improving cutting quality.

What Is AlN Laser Cutting?

AlN laser cutting is a precise method used to shape and trim aluminum nitride, a ceramic material known for its excellent thermal conductivity and electrical insulation properties. This technique utilizes a high-powered laser beam focused onto the AlN surface, which melts or vaporizes the material in a controlled manner. The precision of the laser makes it ideal for creating intricate designs and patterns, particularly in applications requiring tight tolerances.

Unlike traditional cutting methods, laser cutting does not involve physical contact with the material, reducing the risk of mechanical damage. However, while the method is efficient, it does require careful control of various factors to avoid undesirable results like blackened edges.

Where Is AlN Laser Cutting Used?

AlN laser cutting is commonly used in industries such as electronics, automotive, aerospace, and telecommunications. In the electronics industry, AlN is often used for components like heat sinks, substrates, and high-power devices that require both thermal conductivity and electrical insulation. In aerospace and automotive sectors, AlN is used for its ability to withstand high temperatures and provide efficient heat dissipation.

Given the growing demand for miniaturized and high-performance components, AlN laser cutting is becoming increasingly popular for fabricating small, complex parts that need to meet high reliability standards.

What Are Common Problems Occurred During AlN Laser Cutting?

While AlN laser cutting offers numerous advantages, it’s not without its challenges. One of the most common issues is blackening along the cut edges. Other problems include excessive heat buildup, poor edge quality, material cracking, and the formation of burrs. Each of these issues can affect the overall performance of the component and increase post-processing requirements.

However, most of these problems can be mitigated with proper adjustments to the laser cutting parameters and the right choice of assist gases. Understanding the root causes of these issues is essential for improving the quality and efficiency of the laser cutting process.

Why Does AlN Blacken During Laser Cutting?

Blackening during AlN laser cutting occurs primarily due to oxidation and overheating. Here’s a breakdown of the causes:

Oxidation: AlN is a combination of aluminum and nitrogen. When exposed to high heat from the laser, especially in the presence of oxygen, the aluminum reacts with the oxygen to form aluminum oxide (Al₂O₃). This oxide layer appears as a dark, blackened surface, which is often undesirable for aesthetic and functional reasons.

Overheating: If the laser power is too high or the cutting speed is too slow, excess heat can build up in the AlN material. This can lead to degradation, resulting in the formation of carbon or other residues that further contribute to blackening.

Assist Gases: The choice of assist gases plays a significant role in the oxidation process. Oxygen-based gases promote oxidation, while inert gases like nitrogen help prevent it. If the wrong gas is used or the pressure is incorrectly adjusted, the material can oxidize, leading to unwanted blackened edges.

What Is the Role of Laser Power and Speed in AlN Cutting Quality?

Laser power and speed are two crucial factors that directly influence the quality of AlN cuts. Here’s how each affects the process:

Laser Power: High laser power can easily overheat the material, increasing the chances of oxidation and degradation. Reducing the laser power ensures that the material is not exposed to excessive heat, helping to maintain the integrity of the cut and preventing blackening. It also allows for more controlled cutting, especially for thin AlN materials.

Cutting Speed: The speed at which the laser moves across the material is equally important. If the laser moves too slowly, it can lead to excessive heat accumulation in one spot, leading to overheating and blackening. On the other hand, if the speed is too fast, the laser may not have enough time to make a clean cut. Finding the right balance between power and speed is key to achieving clean, high-quality cuts

How Assist Gases Affect AlN Laser Cutting and Blackening

Assist gases are used in laser cutting to clear the molten material from the cut area and help with heat dissipation. They also have a significant impact on the final surface quality of AlN cuts:

Nitrogen: Nitrogen is an inert gas that doesn’t react with the material. It creates a non-oxidizing atmosphere that helps prevent blackening and oxidation. Using nitrogen as an assist gas is ideal for cutting AlN without introducing unwanted discoloration.

Oxygen: Oxygen is often used when cutting materials that require faster cutting speeds. While it improves cutting efficiency, it also increases the likelihood of oxidation, leading to blackened edges. Careful control of oxygen pressure and flow can help minimize this effect.

Air: Air contains oxygen, which promotes oxidation. Using air as an assist gas for AlN laser cutting is generally not recommended, as it can exacerbate the blackening issue. If air is used, adjustments to other parameters (like laser power and speed) will be necessary to avoid oxidation.

How to Prevent Blackening During AlN Laser Cutting

Preventing blackening during AlN laser cutting involves several strategies:

Adjust Laser Power and Speed: Reduce the laser power to prevent overheating, and adjust the cutting speed to minimize heat buildup. Balancing these two factors is essential for clean cuts.

Use Nitrogen as an Assist Gas: Nitrogen prevents oxidation and helps maintain the material’s quality during cutting. Ensure that nitrogen pressure is high enough (between 5-10 bar) to help expel molten material from the cutting zone.

Proper Laser Focusing: Ensure the laser is properly focused to control the heat distribution. A well-focused laser beam reduces the chances of excessive heat and blackening.

What Is the Best Cooling Method for Preventing Overheating and Blackening in AlN?

Effective cooling is essential for preventing overheating, which can lead to blackening. Some of the best cooling methods include:

Air Cooling: Using compressed air or directed air streams can help dissipate excess heat from the cutting zone, preventing the material from overheating.

Water-Cooled Beds: Incorporating water-cooled beds or a water-based cooling system can also help regulate the temperature during cutting, ensuring that the AlN material remains at an optimal temperature.

Controlled Ambient Temperature: Maintaining a stable temperature in the cutting environment can also reduce the risk of overheating, especially in high-precision applications.

Are There Post-Processing Techniques to Restore AlN Surfaces After Laser Cutting?

If blackening does occur during AlN laser cutting, there are several post-processing methods that can help restore the material’s appearance:

Chemical Cleaning: Acid washing using hydrochloric or phosphoric acid can remove oxidation and restore the AlN surface without damaging the material.

Mechanical Polishing: For larger areas of blackening, mechanical polishing with abrasive pads can smooth out the surface and remove any discoloration.

Laser Polishing: A more advanced technique, laser polishing, involves using a laser to melt the surface slightly and smooth out imperfections. This method provides a highly precise finish and can be used to remove any blackened areas.

Blackening during AlN laser cutting is a common issue that can affect both the aesthetic and functional properties of the material. However, by optimizing laser parameters, choosing the right assist gases, and incorporating cooling systems, manufacturers can significantly reduce or eliminate blackening. Additionally, post-processing techniques like chemical cleaning and polishing can further improve the surface quality. With the right approach, you can achieve clean, high-quality AlN cuts that meet both performance and appearance standards.

Working with ceramic PCBs in ultra-high vacuum (UHV) environments presents several complex challenges that require careful consideration. Outgassing, mechanical stress, and electrical stability are among the most significant concerns.

To ensure the integrity and longevity of ceramic PCBs in these extreme conditions, each of these issues must be addressed through tailored strategies. These strategies may include using high-purity materials, implementing effective grounding techniques, and optimizing thermal expansion properties to mitigate the challenges and maximize the PCB’s performance over time.

How Does Outgassing Affect Ceramic PCBs in UHV?

Outgassing is the release of gases trapped within the material when exposed to vacuum conditions. This is a major concern for ceramic PCBs in UHV, as the outgassed materials can contaminate the vacuum and affect sensitive equipment. When ceramics are used in UHV, any residual moisture, oils, or other volatile components may vaporize and disrupt the environment.

To address outgassing, ceramic PCBs should undergo a degassing process, often referred to as a “bake-out.” This procedure involves heating the ceramic material in a vacuum chamber to expel trapped gases. Additionally, using high-purity ceramics that have low outgassing rates can help minimize contamination risks and enhance the performance of the ceramic PCBs in UHV environments.

What Are the Mechanical Strength Issues for Ceramic PCBs in UHV?

Ceramic PCBs are highly valued for their thermal and electrical properties, but they are more brittle compared to metals. In UHV conditions, mechanical stress caused by thermal cycling, shock, or vibrations can lead to cracking or failure. This brittleness is especially concerning during launch, transport, or in operations where the ceramic PCB might be exposed to sudden shocks or vibrations.

To improve the mechanical strength of ceramic PCBs in UHV, it’s important to use high-quality, reinforced ceramics such as aluminum nitride (AlN) or silicon carbide (SiC). These materials offer better strength and fracture resistance. Furthermore, packaging and mounting the ceramic PCBs carefully can reduce stress and prevent mechanical damage during handling or operation.

How Do Thermal Expansion Issues Impact Ceramic PCBs in UHV?

Thermal expansion is another concern when working with ceramic PCBs in ultra-high vacuum conditions. Ceramic materials typically have a lower thermal expansion coefficient compared to metals. This can cause issues when ceramic PCBs are used alongside other materials, such as metal connectors or solder joints, which may expand or contract at different rates. The resulting mechanical stress can lead to cracks or fractures, especially under extreme temperature fluctuations.

To mitigate thermal expansion issues, it’s essential to match the ceramic PCB material with metals or alloys that have similar thermal expansion rates. This helps prevent mechanical stress and ensures that the components remain intact even when temperatures fluctuate dramatically in the UHV environment.

How Does UHV Affect the Electrical Performance of Ceramic PCBs?

The absence of air in ultra-high vacuum environments can also affect the electrical performance of ceramic PCBs. In a vacuum, there’s no air to dissipate static charges, which can lead to issues such as electrostatic discharge (ESD). Additionally, high-voltage applications in UHV can be prone to corona discharge, a phenomenon where electrical breakdown occurs in the air or vacuum.

To ensure stable electrical performance, designers must incorporate specific features into the ceramic PCB design. For example, shielding, grounding techniques, and the use of anti-static coatings can help mitigate static charge build-up and reduce the risk of electrical discharge. These measures will help maintain the PCB’s reliability in UHV conditions, preventing interference with sensitive equipment and experiments.

How Can Surface Contamination Impact Ceramic PCBs in UHV?

In ultra-high vacuum environments, even the smallest particle or impurity can significantly affect the performance of sensitive instruments. Surface contamination on ceramic PCBs can lead to outgassing, which contaminates the vacuum and disrupts the operation of surrounding systems. Oils, dust, or foreign particles on the ceramic surface are common contaminants that can negatively impact performance.

To avoid contamination, ceramic PCBs should be thoroughly cleaned before use in UHV conditions. Cleaning methods such as ultrasonic cleaning, chemical cleaning, or using specialized solvents can help remove impurities from the PCB surface. Once cleaned, the PCBs should be handled in cleanroom environments to prevent recontamination.

What Are the Long-Term Effects of UHV on Ceramic Materials?

Exposure to ultra-high vacuum over extended periods can lead to material degradation. For example, high-energy particles, such as cosmic rays or X-rays, can alter the properties of ceramic materials. This degradation can manifest as changes in electrical conductivity, mechanical strength, or thermal performance. Over time, prolonged exposure to UHV can compromise the PCB’s integrity.

To minimize the long-term effects of UHV exposure, it is crucial to select ceramics that are specifically engineered for vacuum environments. These materials should be resistant to radiation and able to maintain their properties under extended exposure to UHV. Regular inspection and maintenance are also essential to ensure the continued performance of ceramic PCBs in such demanding conditions.

How Can Ceramic PCBs Be Optimized for UHV Environments?

To optimize ceramic PCBs for ultra-high vacuum environments, a combination of factors must be considered. First, using high-purity ceramics with low outgassing rates is essential for ensuring that the PCB does not contaminate the vacuum. Secondly, proper thermal and mechanical design can help prevent issues related to thermal expansion and mechanical stress. Lastly, regular cleaning and maintenance procedures are necessary to maintain the integrity of the ceramic PCBs and avoid contamination.

By addressing these considerations, ceramic PCBs can function effectively in UHV applications, offering exceptional performance in even the most extreme conditions.

Ceramic PCBs in Ultra-High Vacuum Environments play a critical role in various high-performance fields, offering superior thermal, electrical, and mechanical properties.
