Sealing for High-tech Devices: Glob Tops and Dam-Fill Encapsulants

Glob tops and dam-fill encapsulants are epoxies used to seal chips in chip-on-board applications. Their design provides both environmental protection (meeting the latest Europe green requirements) as well as enhancement of mechanical robustness for fragile semiconductor devices, components, and wire bond packages.

These materials are highly filled with silica filler for low coefficient of thermal expansion or CTE. The CTE measures how much the material expands at different temperatures. We utilize high purity epoxy resins to protect sensitive electrical components since some epoxies will emit chemicals such as chlorine gas, which affects performance.

Our encapsulants can be applied in two different ways to protect sensitive components. These methods are the Dam-and-Fill Process and glob top Process. Let’s discuss each in more detail next.

Dam and Fill Process for Encapsulants

An encapsulant manufactured via the Dam and Fill Process. The encapsulant creates a protective barrier around the high-tech components.

First, we dispense a viscous material to create a dam around the perimeter of components. We formulate this material to have a high aspect ratio after dispensing in order to provide a protective barrier. After the wall is completed around the parts, a second material, called the fill, is dispensed with good flow to fill the cavity. This material has self-leveling characteristics so that it can create a smooth, flat top so that it can fit inside the electronic device without adding bulk.

Glob Top Process for Encapsulants

In glob top encapsulation, sealant is applied directly to the sensitive electronics to protect crucial components and devices.

The glob top process is slightly different. In this process, encapsulant material is dispensed directly to an area to protect critical components and devices.  The glob top material is first dispensed onto the component using a needle. The material will flow to cover the component. There is a need to control rheology (material flow properties) so that the material flows enough to cover the component but doesn’t spread to adjacent parts.

What Glob Tops and Dam-Fill Encapsulants?

Our encapsulants and sealants provide features and benefits including:

• Outstanding adhesion to a wide variety of substrates
• High glass transition temperature or Tg – which means better encapsulation and protection
• Low CTE for use near highly sensitive electronic devices and high-tech components
• High modulus (stiffness) for strength and robustness
• Design for high reliability and harsh environments (mainly automotive and industrial applications, but also medical uses such as pacemakers)
• Excellent insulation (high bias voltage) to protect critical components
• Designed for high volume production, capable of jet or syringe dispensing, with long pot life and fast curing time.
• Compliance with the European Union’s REACH and RoHS requirements for not containing hazardous materials

NAMICS outshines the competitors through excellent, efficient customer service. Our lead times are shorter than those of our competitors. NAMICS products are designed to meet upcoming European environmental requirements which begin in 2023.

Meaning of NAMICS

NAMICS is our company’s name. It also represents our values and corporate philosophy. NAMICS is an acronym for Nature, Art, Mutual prosperity, Innovation, Creativity, and Sensitivity. Keep reading to learn more about the different aspects of NAMICS’ name.

Nature & Art

NAMICS promotes harmonious coexistence between nature and mankind. While NAMICS’ key focus is developing chemicals for the semiconductor and electronics market, we do so with the environment in mind. Our headquarters, factory, and technical center are surrounded by rich harvest fields and vibrant fishing industry. Protection of these vital natural resources is paramount for NAMICS.

Since November 2003, NAMICS has acquired and maintained an ISO14001 certificate as the cornerstone of our environmental management system. Our goal is to actively promote environmental conservation activities through waste recycling, energy conservation, green procurement, and pollution protection.

One of our key goals, since NAMICS’ inception, is environmental protection. That’s why we offer environmental training for our employees. We also offer environmentally-conscious product development: our products are lead-free and have a long shelf life to reduce waste. We do not use harmful substances and our products are compliant with Restriction of Hazardous Substance (RoHS) guidelines. Our green procurement standards – the purchasing criteria we use to help mitigate environmental impacts – are also focused on selecting products with minimal environmental impact.

Our facilities are also designed with environmental sustainability in mind – they are designed to maintain clean water and fresh air to our local environment. We minimize our daily energy use with an annual energy savings plan. We also reduce waste through recycling of generated waste products.

Sensitivity

NAMICS is an R&D-oriented company requiring a logical way of thinking. However, that is not all – a global perspective and flexible thinking are also critical. Because we create entirely new things that are not in already there in the world, things like technical possibilities, efficiency of production, or cost-effectiveness sometimes take a backseat to “thinking big.” Expressing ideals and talking about dreams — so to speak, being able to freely ideate – is also required to come up with our next great product.

Sensitivity deals with noticing the nuances – whether cultural, geographic, or other details – that can be helpful in tackling big challenges. Sensitivity is needed to understand how to perceive an event, how to recognize the problem, and how to sense the emotions of others. Sensitivity leads to communication skills and is the backbone of human resource education.

NAMICS is committed to promoting cultural sensitivity via expansion of overseas deployment. Our human resources team possesses knowledge of foreign languages, cultures, and values. We have a nuanced knowledge of intellectual property rights management, including the acquisition of patents and trademark rights, and continue to promote our employees to continue their education.

NAMICS New Adhesive Enables Next-Generation, Flexible Hybrid Electronics

NAMICS New Adhesive Enables Next-Generation,
Flexible Hybrid Electronics

For over 70 years, NAMICS has been a global technology leader in advanced materials used in the manufacture of semiconductor devices. We are excited to announce our newest product, H9230D, a stretchable conductive adhesive. This new material is designed for flexible hybrid electronics – a new and exciting area in electronics which boasts both flexibility of lightweight and thin circuit boards, as well as the processing power of semiconductors.

What Are Flexible Hybrid Electronics (FHE)?

Hybrid electronics are a new growing area of the electronics industry, powered by increasing demand from consumers for more wearable and flexible products, as well as demands from industry to enable new applications. Flexible hybrid electronics have created a broad range of new applications across many industry segments, including the Internet of Things (IoT), smart buildings, healthcare, product packaging, retail, consumer electronics (including wearable devices), automotive, aerospace, and other emerging chip markets.
Specific applications of flexible hybrid electronics include touch control, lighting, sensors, low-frequency wireless devices, and innovative signage, including solar-powered and flexible displays.

What Are the Benefits of NAMICS’ New Adhesive, H9230D, for FHE?

H9230D is a new stretchable, conductive adhesive that is used to mount rigid components onto flexible hybrid substrates while providing an electrically conductive path. Our H9230D was designed for attaching components such as LEDs, capacitors, and small chips to flexible substrates. New component attachment materials are needed for flexible electronic devices which, because they are mounted on soft, flexible substrates, and require materials to be ductile.

One challenge in fabrication of FHE is temperature limitations which mean that conventional soldering can damage the electrical components. Because the thin, low-cost substrates used in FHE are temperature-sensitive, soldering must be done in a way that allows for heat dissipation. This can add complexity to the FHE manufacturing process.

H9230D provides an ideal alternative to solder for FHE applications. While adhesives must be cured, the temperature requirements for affixing conductive adhesives are much lower than they are for soldering.

Other features of H9230D include:

• Very low modulus, capable of 3x elongation compared to standard conductive adhesives

• High adhesion strength at low temperatures (e.g., 70C for temperature-sensitive substrates, or snap-cured at 100C for 5 minutes).

• Excellent reliability, withstanding temperature cycle and high humidity testing

• Solvent-free, with very low shrinkage and no voiding

• Designed for high volume manufacturing

• Easy dispensing using standard equipment

• Long pot life of 24 hours

NAMICS H9230D makes next-generation flexible hybrid electronics possible.
