Any layer HDI PCB – What it is and how it works

 Any-Layer HDI, sometimes also called an ELIC – Every Layer Interconnect HDI, is a PCB where each layer is a microvia-based HDI layer, and all the connections between the layers are made using copper filled microvias. This approach has eliminated the need for PTHs for the surface to the bottom layer connection, since both the outer layers can be connected using stacked or staggered copper-filled microvias. This allows for a higher component density by utilizing most of both surfaces. Any-Layer HDI is still being developed and refined. Fabricators are experimenting with new techniques and mate […]

Rigid-Flex PCB Technology

Printed Circuit Boards have been a part of electronics for over 80 years. The first PCB was created in 1936, but PCB technology has come a long way since. Large circuit boards with thick copper lines and through-holes are now reduced to a fraction of the size and thickness of their forefathers. But the most radical changes in the PCB designing have come with HDI and Rigid-Flex, and we will tackle the Rigid-Flex technology today. Rigid-Flex PCB Technology Rigid-Flex can be considered a hybrid of two basic PCB types, Rigid PCB and Flex PCB. Both of these refer to a PCBs mechanical construction. […]

What is High Density Interconnect?

PCB is the backbone of every electronic device. Most of the compactness in your new devices, like continually shrinking smartphones (despite packing a plethora of gadgets), and tiny implants is thanks to the smaller and advanced High Density Interconnect (HDI) PCBs. And small circuits aren’t the only gift of HDI technology. HDI circuits are much better at signal transference than conventional PCBs and they are more suited for high-frequency needs as well. So what is HDI? High Density Interconnect High Density Interconnect simply means more wiring per unit area. With the use of smaller vias, mi […]

Types of HDI PCB Stackup

High-Density Interconnect (HDI) circuits are quickly replacing conventional PCB designing and fabrication techniques. Most compact and sophisticated electronic devices would not have been possible without the advent of HDI. It allowed circuits to become smaller and reliable, even in harsh environmental conditions. Designing an HDI PCB is very different from designing and fabricating a conventional PCB that relies on Plated Through Holes (PTHs) for layer interconnections. Thanks to microvias, HDIs can be created with much more component density than a standard PCB. And like a typical PCB, HDI i […]

Reduce Your PCB Costs with Blind Vias, Buried Vias and Microvias

Printed Circuit Boards (PCB) have come a long way in a short while, but they are still being developed and evolved. PCB fabricators and designers are constantly working to enhance the efficiency, reliability, and ruggedness of circuits, while keeping the manufacturing cost down as much as they can. Considering the complexity of the modern circuits and the necessity for more and more compact circuits, reducing the cost is not an easy task. But there are ways to keep your PCB cost to a manageable level, with the help of blind vias, buried vias, and microvias. Blind Via, Buried Via, and Microvia […]

How to Design the Perfect Flex Circuit

Flex circuits were created to fill the market’s need for compact devices. Flex circuits allow for 3D designing of a circuit, saving a lot of space in the process. They also let the designer create devices without worrying too much about PCB assembly, since Flex circuits can be designed and shaped to fit a particular device. Flex circuits also provide high reliability despite repeated installations, harsh, and high vibration environments. Its flexibility of structure shouldn’t fool you into thinking that it’s design will be just as flexible. Usually, designing a Flex circuit is more complex tha […]

Rigid-Flex PCB Design

Rigid-Flex PCBs are not very recent technology. They evolved from conventional Rigid PCBs and Flex PCBs with stiffeners, to fill the needs of aerospace and military requirements. They are lighter, more reliable, and allow much more design flexibility to the device they are installed in. But these benefits come at a price. Rigid-Flex PCBs are relatively costlier than Flex PCBs with stiffeners, and the designing is more complex. It used to be even more so when the design software wasn’t updated to deal with the pure designing of a rigid-flex. The designers used to break the complete Rigid-Flex P […]

Heavy copper circuits

Various power electronics products are being designed every day for a range of applications. Increasingly, these projects are taking advantage of a growing trend in the printed circuit board industry: heavy copper and extreme copper printed circuit boards. What defines a heavy copper circuit? Most commercially available PCBs are manufactured for low-voltage/low-power applications, with copper traces/planes made up of copper weights ranging from 1/2oz/ft 2 to 3oz/ft 2. A heavy copper circuit is manufactured with copper weights anywhere from 4oz/ft 2 to 20oz/ft 2. Copper weights higher than 20oz […]
