Introducción a la fabricación de placas de circuito impreso multicapa

multilayer PCB manufacturers 

¿Qué es PCB?

PCB significa placas de circuito impreso. En realidad, es una placa muy delgada que almacena información sobre un proceso. Además, puede encontrar una serie de otros fabricantes de PCB multicapa sola capa y doble capa en varias empresas líderes en la fabricación de PCB.

Está hecho de:

  • epoxi compuesto
  • fibra de vidrio o
  • algún otro tipo de material laminado.

Estas vías semiconductoras están impresas o grabadas en una placa que conecta distintos componentes en la PCB como:

  • Resistencias
  • Transistors
  • integrated circuits.

fabricantes de PCB multicapa has become the vital part of today’s most electronic appliances. They control very basic functions via the combinations of wiring mechanisms and sections.

What are uses of PCB?

Although uses of PCB (placa de circuito impreso) has become essential part and almost highly important in all types of electronic gadgets. So, PCBs are mainly used for

  • domestic use
  • industrial purpose.

What are the different types of PCBs?

In the past most of the PCBs were comparatively limited and simple by manufacturing skills. On the other hand, PCBs of modern days are considerably more complex. But today in the world of electronics PCBs have noticeably more varieties that enhances from odd-shaped to advanced flexible options.

En general, existen diferentes tipos de PCB. Entre ellos, el fabricantes de PCB multicapa  proporciona los PCB que lideran por sus mejores especificaciones hoy en día. Todos estos son muy especiales por sus propias especificaciones de fabricación particulares.

1: placa de circuito impreso de una sola capa

PCB de 2: 2 capas

3: PCB multicapa, etc.

En los que los más populares siguen siendo los PCB multicapa.

La PCB multicapa viene con tres o más capas. Estas capas tienen material oculto en el centro. Además, es completamente diferente de la PCB de 2 capas. El fabricante de múltiples capas PCB ‘s  PCBs are glued and covered closely with heat-protective lining between them.

The entire procedure of construction is arranged in such a way that every two layers are placed on the sides of the surface of the PCB in order to connect it with the whole environment.                                                                                                                               All electrical connections between these layers are associated with the following vias like:

  1. plating through holes
  2. blind vias
  • buried vias

multilayer PCBs are mostly used in more complicated electronics such as computer motherboards. consist of multiple layers. These are best examples of multilayer PCBs. Now a days, PCBs produced by the multilayer PCB manufacturer are using like never before in the increasing complexity of modern electronics.

what is multilayer PCB manufacturing?

La fabricación de PCB multicapa en realidad surgió debido a los cambios que se produjeron en la industria de la electrónica. Con el paso del tiempo, las funciones electrónicas se han vuelto más complicadas y, por lo tanto, existe la necesidad de PCB más complicados. Desafortunadamente, en el pasado, los PCB eran muy limitados por alguna razón como:

  • capacitancia parásita
  • diafonía
  • ruido

Por tanto, era necesario adoptar ciertas restricciones de diseño. Pero al final lo hicieron muy complejo y complicado para alcanzar un nivel suficiente de rendimiento de una PCB . Entonces, había una razón para la fabricación de PCB multicapa.

Para desarrollar un PCB multicapa, el material del núcleo conductor y el preimpregnado se laminan estrechamente bajo presión utilizando una prensa hidráulica y una temperatura alta. El calor y la presión hacen que el preimpregnado se derrita y una todas las capas. Todo este proceso asegura que el aire no sea capturado o atrapado entre capas.

La fabricación de PCB multicapa se está volviendo muy popular en la electrónica hoy en día. Además, han llegado en una amplia gama de espesores y tamaños para cubrir las necesidades. En su mayoría, las capas vienen en números pares, porque un número impar de capas puede crear problemas en el circuito, como deformaciones, y su producción es rentable.

¿Cómo seleccionar el mejor fabricante de PCB multicapa?

How to select a best multilayer PCB manufacturer? Is a very important question. For the purpose of proper operation of your device it is very important that you get a perfect multilayer PCB manufacturer. It must have the following characteristics you need

  • Reliable
  • efficient
  • cost-effective

 And there are several reasons for that some are describing below:

Multilayer PCB Applications

Aunque los PCB multicapa se están convirtiendo en mano de obra y más caro para el PCB multicapa  fabricación r. Pero ahora se han convertido en una parte crucial de la tecnología moderna. La causa es que ofrecen grandes beneficios especialmente en comparación con las variedades de PCB de una y dos capas. El fabricante de PCB multicapa  proporciona sus instalaciones a las siguientes tecnologías como:

  • Electrónica de consumo
  • Telecomunicaciones
  • Electrónica informática
  • Industrial
  • Dispositivos médicos
  • Automotor
  • Militar y Defensa
  • Aeroespacial y muchos más.

¿Cuáles son los inconvenientes de la fabricación de PCB multicapa?

 

Since multilayer PCBs developed by a multilayer PCB manufacturer’s advantages are various that make them useful to a vast variety of leading technologies. But in certain cases, such types of PCBs are not appropriate for all kind of applications. Actually, there are various cons of multilayer PCBs just because of such electronics that are low cost but complex.

These cons are :

  • Complicated Production: Multilayer PCBs manufacturing are very difficult to manufacture. They need a very careful manufacturing techniques and extra design time than any other PCBs type.

  • Higher cost: Multilayer PCBs manufacturer needs more and extra expenses to produce multilayer PCBs. They are also very complicated to design. Such multilayer PCBs manufacturing need a highly complicated process. But among all of these the top reason is that the equipment which is actually required in multilayer PCBs manufacturing is really costly. Just because it is even a new and advanced technology.

 

  • Required skilled designer: As we have already discussed that multilayer PCBs need inclusive design. Not even a single mistake is allowed in the design because it can result in a non-functioning very deep.

 

  • Limited Availability: A very big issue with multilayer PCBs is the expenses of machinery which is required to produce them. Hence not all multilayer PCBs manufacturers the more money need to develop them.

 

  • Production Time: Because these PCBs are very complex so they required a vital amount of time. So, in some chances they can be a big problem with an extra labor costs in limited period of time.

Yet these controversies do not reduce the utility of multilayer PCBs manufacturer. Although they favor to charge more than a single layer and a double layer PCB, the advantages of a multilayer PCB could not be denied.

What are multilayer PCB manufacturing pros?

  • Lighter Weight: In a multilayer PCB the integration of components means a less of a need for other components and connectors which results a light-weight solution for composite electrical appliances.

Hence it is an essential evidence for smaller electric appliances where weight is involved.

  • Smaller Size: Overall, in size multilayer PCBs are much smaller than a single layer PCB and a single layer PCB covers a large area. So multicapaPCB manufacturer try to make PCBs that approves for higher-capacity to be used in much smaller devices. But a single layer PCB with a high-capacity equipped into larger products.
  • Higher Assembly Density:Although a single layer PCB’s frequency is limited in comparison to a multilayer PCB whose frequency is multiplied. This expanded frequency approves a greater improving capacity, functionality and speed in spite of the smaller PCB size.
  • Enhanced Design Functionality: Multilayer PCBs can achieve extra despite with their lesser weight and smaller size with greater EMI shielding, more incorporation of controlled impedance features. Hence multilayer PCBs have the ability of being extra in comparison to a single layer PCB.

Conclusion:

 

Hence the result which all these factors provide is when you are looking to develop a lightweight, small and a complex device. El fabricante de múltiples capas PCB’s offers you a quality. Which is also required then a multilayer PCB manufacturing will be your first choice.
