PCB flexível de um lado versus PCB flexível de dois lados. PCB flexível de dupla face versus PCB flexível multicamada.

O Flex PCB de um lado ou o Flex PCB de camada única instala o original em um lado da placa e há um padrão condutor no outro. Uma PCB flexível de camada única tem apenas uma camada de material condutor. A PCB flexível de camada única tem as vantagens de custo mais baixo, design mais fácil, produção, produção em massa e tempo de entrega.

A PCB flexível de dupla face tem mais camadas do que a PCB flexível de camada única, mas menos do que a PCB flexível de várias camadas; a PCB flexível de camada dupla tem uma camada de metal condutor em ambos os lados, o que aumenta a densidade da fiação por unidade de área e é mais adequada para roteamento.

Os circuitos e componentes em ambos os lados da PCB flexível de dupla face podem ser conectados eletricamente por meio de montagem através de orifícios e montagem em superfície.

Três ou mais PCBs flexíveis de dupla face são laminadas em uma PCB flexível de múltiplas camadas. Cada camada de substrato em uma PCB multicamada tem metal condutor em ambos os lados. Esses substratos são colados com um adesivo exclusivo, mas um material isolante separa cada substrato.

A conexão elétrica entre cada camada da PCB flexível multicamada é obtida por meio de orifícios, orifícios cegos ou orifícios enterrados.

As vantagens da PCB flexível multicamada são:

Mais adequada para projetos complexos;

Maior qualidade e confiabilidade;

A densidade dos circuitos de PCB flexível multicamadas é maior, com maior capacidade e velocidade de operação, e o desempenho geral do produto é aprimorado;

Maior durabilidade. Quanto maior o número de camadas da placa de circuito, maior a espessura, portanto, mais durável do que a PCB flexível de um lado ou a PCB flexível de dois lados;

Tamanho menor e peso mais leve: A placa de circuito impresso flexível multicamada apresenta um design de circuito mais compacto, que pode comprimir ainda mais o tamanho e o volume da placa de circuito, reduzindo assim o peso.

Кроме того, существует технология термоэлектрического разделения PCB на основе меди (также известная как технология прямого касания). Это означает, что толщина меди в нужном месте увеличивается с помощью отверстия для покрытия сварочным материалом и гальванической меди, а тепло передается непосредственно от светодиода или других компонентов к медной базе, в то время как сеть цепей независима от тепловой сети.

Как производитель MCPCB, Hitech Circuits производит различные ПХБ на основе меди для своих клиентов.

Для мощных светодиодных ламп (1000 Вт +) и источников питания.

В области светодиодов существует 4 типа платы на основе меди.

[hitechpcb]

Как правило, PCB на основе меди имеет ту же структуру, что и PCB на основе алюминия - однослойная, двухслойная панельная монтажная поверхность, двухслойная двухэлементная монтажная поверхность и четырехслойная двухэлементная монтажная поверхность. Даже если они используют тот же предварительно пропитанный материал для изоляции медного слоя. Однако медная подложка (398W / mK) обладает лучшей теплопроводностью, чем алюминиевая (237W / mK).

What is rigid flex PCB board?

Rigid-flex PCB board, it is a circuit board that combines flexible and rigid circuit board technology in the application. Most rigid-flex boards are composed of multiple layers of flexible circuit boards, which are attached to one or more rigid boards from the outside and/or from the inside, depending on the design of the application. The flexible substrate is designed to be in a constant deflection state, and is usually formed as a deflection curve during rigid flex PCB manufacturing or assembly.
