A Internet das Coisas (Idc) é a conectividade da Internet com dispositivos e objetos do cotidiano.

Um dispositivo IoC é algo com dispositivos eletrônicos integrados, conectividade à Internet e outros tipos de hardware (como detectores ou controladores).

Estes dispositivos podem comunicar e interagir entre si através da Internet.

Isso torna-os fáceis de monitorar e controlar remotamente.

A tecnologia IoC fez grandes mudanças na maneira como controlamos os nossos dispositivos domésticos todos os dias, como o aquecimento, iluminação, segurança e até eletrodomésticos (frigorifico, congelador etc.).

Estes agora podem ser controlados com smartphones, tablets e PCs, não importa onde esteja.

O primeiro dispositivo de IdC foi uma máquina de venda automática da Coca-Cola em 1982, foi conectada à Internet e transmitiu informações sobre o inventário e se as bebidas estavam frias ou não.

Essa tecnologia oferece grandes benefícios, como o monitoramento constante de idosos que moram sozinhos. Por exemplo, um dispositivo pode avisar os profissionais de saúde se a temperatura ambiente cair abaixo de um nível seguro.

Na assistência médica, por exemplo, você pode fornecer feedback ao vivo para pessoas com doenças com risco de vida, mesmo quando estão em casa.

Outro exemplo são as campainhas com câmera, senão está em casa quando alguém toca à campainha, mas o smartphone toca e vpode ver e se comunicar instantaneamente com quem está lá.

Existem tantos aplicativos para a tecnologia IdC que apenas arranhamos a superfície.

À medida que novos dispositivos de IdC são criados todos os dias, uma dinâmica completamente nova esta a iniciar-se no mundo do desenvolvimento da electrónica.

O objetivo agora não é criar sistemas grandes, mas adaptar os sistemas existentes para conectar-se à rede e comunicar com outros dispositivos.

Indo do do ponto do consumidor para aplicações industriais e Indústria 4.0.

Essa evolução multiplicou o número de novos desenvolvimentos de produtos eletrónicos com aplicativos de menor dimensão.

Estes devem estar prontos para o mercado antes de ontem e isso pressiona mais os engenheiros de desenvolvimento e seus fornecedores.

La tecnología IoC ha realizado cambios masivos en la forma en que controlamos nuestros dispositivos domésticos cotidianos, como calefacción, iluminación, seguridad e incluso electrodomésticos (refrigerador, congeladores, etc.).

Ahora se pueden controlar con teléfonos inteligentes, tabletas y PC, sin importar en qué parte del mundo se encuentre.

El primer dispositivo IoC fue una máquina expendedora de Coca-Cola en 1982, estaba conectado a Internet y transmitía información sobre el inventario y si las bebidas estaban frías o no.

Esta tecnología ofrece grandes beneficios, como el monitoreo constante de las personas mayores que viven solas. Por ejemplo, un dispositivo podría advertir a los cuidadores si la temperatura ambiente cae por debajo de un nivel seguro.

En la atención médica, por ejemplo, puede proporcionar retroalimentación en vivo para aquellos con enfermedades que amenazan la vida, incluso cuando están en casa.

Otro ejemplo son los timbres con cámaras, no estás en casa cuando alguien toca el timbre pero suena el teléfono inteligente y puedes ver y comunicarte instantáneamente con quien esté allí.

Hay tantas aplicaciones para la tecnología IoC que solo hemos arañado la superficie.

A medida que se crean nuevos dispositivos IoC todos los días, se ha iniciado una dinámica completamente nueva en el mundo del desarrollo de la electrónica.

El objetivo ahora no radica en crear sistemas grandes sino en adaptar los sistemas existentes para conectarse a la red y comunicarse con otros dispositivos.

Esto va del consumidor a las aplicaciones industriales y a la Industria 4.0.

Esta evolución ha multiplicado el número de nuevos desarrollos de productos electrónicos con aplicaciones más pequeñas que grandes.

Los proyectos deben estar listos para el mercado antes de ayer y esto ejerce más presión sobre los ingenieros de desarrollo y sus proveedores.

Defined Impedance Calculators

/in , , /by
Defined Impedance Calculator Banner

There are many different Impedance calculators for PCB designers to use, some are free such as the one available to Eurocircuits customers and some you need to pay for a licence or a monthly subscription.

The aim of them all is to provide the necessary track/gap and isolation values for the layout and manufacture of your PCB.

The interfaces vary from one to another as does the way you input the parameters that are used by the calculator and this is where a user must take care.

Since the very successful launch of the Eurocircuits DEFINED IMPEDANCE pool service we have received feedback that results between our calculator and others varies.

This is something that we took very seriously and launched an investigation to establish why there was a difference.

What We Discovered

It turned out that the parameters required for one system were different to another. For example, the value H1 in our calculator is not the same as H1 in another calculator.

In the example below it is in fact the H2 in the other calculator.

Different Calculator Input Graphic

Magnified Graphic of Buildup & Parameters

In addition, the H2 value in the other system is actually equal to H1 + T in our calculator as above.

Therefore, adding the same values for H1 & H2 in the Eurocircuits calculator compared to another may very well deliver different results, as the corresponding input parameters may differ.

To verify that the Eurocircuits calculator provides the correct results we ran several tests:

  • Firstly, we used the same parameters in our calculator and the Altium calculator and as expected the results we different.
  • We then corrected the parameters used in the Altium calculator to what they require (e.g. H1+T) and the results were extremely close (Zdiff = 100.035E vs 99.146463E).

It is important to use the correct dielectric constant (εr) value for the selected material.

This value will change depending upon the selected frequency.

In the Eurocircuits calculator all the known values are automatically updated based on the selected build-up.

Another point to be aware of is how the calculator generates the results. Is it calculated using the correct formula or simply using a known ‘Rule of Thumb’ equation?

For example, a ‘Rule of Thumb’ equation for a Differential Impedance value is 2x that of the Characteristic Impedance value.

This is only a rough and non-mathematical value which may vary significantly from the real value.

It is important to check how these values are derived?

Conclusion

When using an impedance calculator, you must ensure that the actual values entered, correspond to the parameters required and are not simply copied from one calculator to the next:

  • Eurocircuits’ Impedance calculator uses real values as defined in the supplier’s data sheets.
  • Eurocircuits also calculates the correct Differential Impedance values using the correct formula and not a ‘Rule of Thumb’ method.

Finally, all calculators provide theoretical impedance values as they cannot take in to account the variables and tolerances of the manufacturing process.

This means that whilst the calculator gives you a value, the actual value measured on the PCB may well be different.

It is Eurocircuits’ experience that the measured values on the PCB are within a ±10% of our calculated values.

Insight Technology – Finished PCB Thickness Tolerances

/in /by

Definition of Tolerance for Manufacturing

Manufacturing tolerances are the amount of variation that is allowed in a measurement or other characteristic of an object.

Ref: Collins English Dictionary

We continue with our series on Understanding Tolerances on a PCB with our 5th guide:

Finished PCB Thickness Tolerances

As with all manufacturing processes the Finished PCB Thickness is influenced by various factors and thus there is a tolerance applied to the final thickness.

The process of manufacturing a PCB starts with the Base Materials (e.g. FR4) and these are available in various thicknesses.

Base material thicknesses have a tolerance as defined by the manufacture, for example for FR4 this is ±10%.

Added to this are the various other tolerances accumulated throughout the manufacturing process and this is where the Final PCB Thickness Tolerance is derived from.

We always comply with the IPC-A-600 Acceptability of Printed Boards (Industrial products) standards for PCB thickness measurement and tolerance.

The thickness of a PCB must be measured on an area of laminate that is free of Soldermask, copper and legend.

Definition of Tolerance for Manufacturing

Manufacturing tolerances are the amount of variation that is allowed in a measurement or other characteristic of an object.

Ref: Collins English Dictionary

We continue with our series on Understanding Tolerances on a PCB with our 4th guide:

Slot Size Tolerances

The definition of a slot is “a narrow-elongated slit or aperture”.

We define a slot or cut-out as an aperture inside of the PCB profile but differentiate between them from a production point of view.

A slot is simply an elongated hole whereas a cut-out, is another hole of any shape, see image below.

Slots are very common on PCB’s and like holes they can be plated (PTH) or non-plated (NPTH).

The purpose of slots varies, the most common use is for component mounting.

Other uses are for cable pass throughs, ventilation, electrical isolation etc.

The Finished Slot Size like holes are influenced by various factors during the manufacturing process as below:

  • Type of Slot – Plated or Non-Plated.
  • Nominal Slot Size vs available tool sizes.
  • Tool Size Tolerance.
  • Tool Wear during use.
  • Slot Cleaning (Desmear).
  • The Plating Process and Copper Balance.
  • The Final Surface Finish of the PCB.

We use our knowledge of the PCB manufacturing process to ensure that the finish slot size is within the accepted tolerance.

We produce all our boards according to the IPC-A-600 Acceptability of Printed Boards (Industrial products).

The Internet of things (IoT) is the Internet connectivity to devices and everyday objects.

An IoT device is something with embedded electronics, Internet connectivity and other types of hardware (such as detectors or controllers).

And these devices can communicate and interact with each other via the Internet.

This makes them easy to monitor and remotely control.

IoT technology has made massive changes to the way we control our everyday household devices such as heating, lighting, security and even home appliances (fridge, freezers etc).

These can now be controlled by smartphones, tablets and PC’s no matter where you are in the world.

The first ever IoT device was a Coke vending machine in 1982.

It was connected to the internet and relayed information on the inventory and whether the drinks were cold or not.

This technology brings great benefits such as, constant monitoring of elderly people living alone. For example, a device could warn carers if the room temperature falls below a safe level.

In medical care for example, it can provide live feedback for those with life threatening illness even when they are at home.

Another example is the door bells with cameras, you’re not home when someone rings your bell but your smartphone rings and you can instantly see and communicate with whoever is there.

There are so many applications for IoT technology that we have only just scratched the surface.

As new IoT devices are being created every day it has initiated a whole new dynamic in the world of electronics development.

The focus now does not lie with creating large systems but in adapting existing systems to connect to the net and communicate with other devices.

This goes from consumer to industrial applications and into Industry 4.0.

This evolution has multiplied the number of new electronic product developments with smaller rather than bigger applications.

They have to be market ready by yesterday and this puts more pressure on the development engineers and their suppliers.

How Does Eurocircuits Help?

We have invested heavily in this trend to support our customers by offering them faster and more dynamic services as below:

  • PCB proto – 3 Working Days Delivery as Standard down from 7 WD in January 2019.
  • STANDARD pool, RF pool and IMS pool – 5 Working Days Delivery as Standard down from 7 WD only 3 weeks ago.

Making sure that your project meet your “TIME to MARKET” expectations.

 

 

 

 

Insight Technology – Layer to Layer Registration Tolerances

/in /by

Definition of Tolerance for Manufacturing

Manufacturing tolerances are the amount of variation that is allowed in a measurement or other characteristic of an object.

Ref: Collins English Dictionary

We continue with our series on Understanding Tolerances on a PCB with our latest guide:

Layer to Layer Registration Tolerances

The accuracy of layer to layer registration is one of the most important parts of the PCB production process.

Get it wrong and the holes may breakout of the copper pads.

Our goal is always to deliver your PCB’s with the layer to layer registration accuracy as close to perfect as possible.

However, there are many factors that influence this accuracy and we use our experience and expertise to compensate for them during production.

One of the latest and most important additions to our factories has been Direct Imaging (DI).

Using DI for the imaging of the copper layers and Soldermask has enabled us to improve our registration capabilities as it eliminates the need for Photo-tools.

Photo-tools are extremely sensitive to temperature and humidity and will distort with the smallest of change in either of these.

DI is digital printing and uses state-if-the-art CCD cameras to detect predefined targets (holes or fiducials).

These are then used to align the image to the panel.

For inner layers it even prints the targets directly on L3 using a UV Marker system whilst it prints L2,

This greatly improves the layer to layer registration accuracy for inner layer cores.

We produce all our boards according to the IPC-A-600 Acceptability of Printed Boards  (Industrial products).
