Select Material for Your PCBs from Cost and Reliability Considerations

At BST Ceramic PCB, we know well how important the choice of material can be to the performance and the useful life of the PCBs. It may be difficult to determine where economy of cost can be optimally achieved without sacrificing dependability, especially when the choices are countless.

In this article, we will provide you with information to make better decisions when choosing material for your PCBs.

FR-4: The Ever Reliable Material

FR-4, a flame retardant epoxy laminate stays as the leading option for a reason. Due to its inexpensive cost, it is relatively easy to manufacture resulting in its decent electrical characteristics that make it suitable for general low to medium-frequency applications.

However, for your project, as it scales up, you will see the drawbacks of FR-4 very clearly. Operating with higher temperatures, high-frequency signal transmission, and restricted dimensionality challenge the FR-4 board’s reliability limits.

Aluminium Based PCBs

When it comes to high-end and highly critical applications, application-specific alumina ceramic PCBs turn out to be a distinct possibility. Here is why alumina PCBs are the perfect choice:

BestThermalManagement: Alumina possesses dissipation of heat that is associated with high-power devices since it has good thermal conductivity. This means that the system boards can operate at lower temperatures and ensure a longer life for the PCBs used and the reliability of the equipment.

High-Frequency: Alumina's low dielectric constant (Dk) and low dissipation factor (Df) minimize signal loss, making it ideal for high-frequency applications like RF circuits and communication devices.This translates to reliable signal transmission, crucial for error-free operation.

Built to last: Alumina boasts of being highly mechanical and chemically sound with a very high level of dimensional stability as well as the ability to resist warping and harsh chemical, atmospheric and temperature gradients.

Alumina PCBs higher price in comparison with FR-4 can be observed in the primary stage but if one looks intothe overall picture there is a possibility to get more for less. This may make it possible to decrease the utilization of big heatsinks which in turn makes the design of the PCB lighter. Besides, the longevity decreases the chance of early PCB failure, and therefore, expensive replacements.

At BST Ceramic PCBs, we specialize in high-quality alumina PCBs. Please feel free to contact us right now and tell us your project specifications to know about possible ways to improve your design with our alumina ceramic PCBs performance and affordability.

Quais foram os avanços tecnológicos alcançados pelas PCBs de cerâmica?

I. O que é cerâmica técnica?

Também conhecidas como “de engenharia” ou “avançadas”, as cerâmicas técnicas são materiais de substrato cerâmico com excelentes propriedades elétricas, mecânicas e térmicas. Esses materiais são aprimorados e personalizados por meio de sua composição química para fornecer propriedades aprimoradas e específicas necessárias para uma ampla gama de aplicações no setor de eletrônicos. O tipo mais comum é o nitreto de silício, um material cerâmico composto de silício e nitrogênio, enquanto outros são feitos de zircônia, titanato de alumínio ou compostos de matriz metálica.

Como os substratos de cerâmica técnica são usados na eletrônica.

A espinha dorsal da aplicação do setor de substratos cerâmicos técnicos é o nível de fabricação de componentes, em que diferentes composições de placas cerâmicas são usadas para criar vários componentes com propriedades isolantes, dielétricas, piezoelétricas ou magnéticas, enquanto esses materiais também fornecem proteção estrutural hermética para a maioria dos circuitos integrados.

As composições de substrato de cerâmica que apresentam baixa condutividade, como o óxido de alumínio, são ideais para o projeto de componentes passivos. Esses tipos de cerâmica são usados em capacitores de cerâmica multicamada ou MLCCs para separar as várias camadas de eletrodos que compõem o componente. Elas também são usadas em resistores para dissipar a energia na forma de calor. Outros componentes de substrato de cerâmica podem permear campos magnéticos, o que os torna adequados para uso na fabricação de indutores, onde as cerâmicas são combinadas com óxido de ferro e carbonato de estrôncio para formar cerâmicas altamente magnéticas, também conhecidas como “ferritas”.

Embora as cerâmicas de engenharia sejam preferidas por suas propriedades isolantes exclusivas, certas composições podem ser usadas para fabricar semicondutores ou materiais supercondutores. Há muitos outros tipos de placas de cerâmica técnica com propriedades diferentes para várias aplicações no setor de eletrônicos, cujos exemplos são descritos a seguir.

3. Aplicações potenciais de substratos de cerâmica técnica no setor de eletrônicos

A natureza prática das placas de cerâmica técnica significa que elas são cada vez mais relevantes para todas as áreas do setor de eletrônicos e, nas próximas três subseções, apresentaremos alguns exemplos importantes de aplicações do setor relacionadas a essa tecnologia.

a. PCBs flexíveis

Como a tendência geral da eletrônica parece ser a miniaturização, o setor de eletrônicos está constantemente buscando criar dispositivos eletrônicos cada vez mais compactos. Uma dessas aplicações são as placas de circuito impresso ou PCBs, que podem ser dobradas e colocadas em compartimentos muito menores do que as placas planas e rígidas. As PCBs flexíveis à base de cobre já estão em uso atualmente, mas são limitadas na prática porque a maioria das PCBs flexíveis exige seções rígidas para manter os componentes no lugar. Mais importante ainda, as seções flexíveis limitam-se a fixar as conexões e interconexões de cobre da PCB.

O principal motivo é que os componentes eletrônicos são rígidos e não podem ser colocados em superfícies curvas. Essa é uma área em que as placas de cerâmica flexíveis podem prosperar. Se uma combinação de polímeros e pós de cerâmica puder ser usada para fabricar componentes tradicionais, isso poderá dar início a uma nova era de dispositivos flexíveis e miniaturizados.

b. Substratos e embalagens de cerâmica

Com a crescente demanda por sistemas em um chip altamente integrados e repletos de recursos, o que, obviamente, impõe demandas rigorosas de processamento de sinais, potência e dissipação de calor, esforços significativos de pesquisa em ciência dos materiais foram direcionados para o desenvolvimento de composições cerâmicas aprimoradas com menor O substrato de alumina, que é o substrato mais usado no setor atualmente, tem uma constante dielétrica mais alta e maior condutividade.

As matrizes de componentes de interconexão construídas em chips de silício, também conhecidas como circuitos integrados, tradicionalmente usam substratos e embalagens de cerâmica que fornecem isolamento elétrico e suportes mecânicos hermeticamente fechados. Com suas excelentes propriedades mecânicas e térmicas, os substratos de cerâmica técnica podem produzir substratos e materiais de embalagem aprimorados e duráveis.

c. Supercapacitores de cerâmica como dispositivos de armazenamento de energia de alta densidade

A fabricação de supercapacitores percorreu um longo caminho nos últimos anos. Isso se deve principalmente à demanda por dispositivos de armazenamento de energia mais eficientes do que os oferecidos pelas baterias, que têm alta densidade de energia, mas um número limitado de ciclos de carga/descarga (mesmo em veículos elétricos); além disso, elas são afetadas negativamente por altas temperaturas. Por outro lado, os ultracapacitores têm milhões de ciclos de carga/descarga e degradação mínima durante sua vida útil. Eles atenuam muitas das limitações das baterias, apesar de sua capacidade limitada de armazenamento de energia.

Os supercapacitores têm muitas das mesmas propriedades, embora sejam construídos de uma maneira diferente dos capacitores comuns. Embora isso possa torná-los um substituto ideal para as baterias, os ultracapacitores são dispositivos grandes baseados em eletrólitos. Isso significa que há um processo complexo de fabricação e projeto para qualquer engenheiro que deseje fabricar e expandir a tecnologia para uso em dispositivos miniaturizados. Como resultado, há uma necessidade de supercapacitores de estado sólido que possam ser usados para alimentar dispositivos menores, e os substratos de cerâmica técnica podem ser um candidato para o setor de eletrônicos.

4. Potencial de crescimento dos substratos de cerâmica técnica

As cerâmicas técnicas, também conhecidas como cerâmicas de engenharia, embora suas aplicações úteis sejam principalmente em nível de matéria-prima, devem continuar a ser relevantes para o setor de eletrônicos em rápido desenvolvimento, especialmente devido às qualidades mencionadas anteriormente, como suas excelentes propriedades elétricas, mecânicas e térmicas.

Os substratos de cerâmica técnica são aprimorados e personalizados por meio de sua composição química para proporcionar melhor desempenho para uma ampla gama de aplicações eletrônicas. A crescente demanda por dispositivos eletrônicos altamente integrados e eficientes continuará a impulsionar a pesquisa no desenvolvimento de materiais cerâmicos técnicos.

What is PCB Assembly?

 It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.
