Types of Laminates Used for Printed Circuit Boards

30 - May - 2017

A cursory glance at a Printed Circuit Board (PCB) shows it to be a simple board overlaid with an intricate design of tracks and lands. A closer look reveals several details involved with creating the PCB—the tracks and lands of copper covered with solder mask, and on the top, the silk screen showing the positions of various components. The base material is the laminate, of which .... Read more

Design Tips for Flex Circuit Boards

23 - May - 2017

Flex circuit boards offer designers several benefits. The capability of the flex circuit to assume three-dimensional configurations along with vibration resistance are the major reasons for designers adopting this technology for their products. However, this capability comes at a price. As their name suggests, flex circuit boards can bend, whereas SMD components mounted on them .... Read more

Protecting Your Designs against Product Piracy

06 - May - 2017

Most modern electronic systems are embedded systems, in the sense that they are miniature computers working within their application-oriented context. Common functions they share are measurement, control, regulation, data monitoring, and signal processing. Usually, the underlying computer system is a highly specialized unit, with both the hardware and software or firmware optimize.... Read more

Trends in Flex Printed Circuit Boards

30 - Apr - 2017

The last 25 years or so have been a sea change in the electronic industry. The speed of technology is changing at a geometric rate. Where earlier mobile phones were the size of shoes, now there are slim smart phones that easily slip into a shirt pocket. The changes expected in the next two decades will make the previous decades pale in comparison. One of.... Read more

Using Laser Direct Imaging in Fabricating PCBs

15 - Apr - 2017

In the fast-moving world today, people quickly lose interest in the current model of an electronic gadget. This forces OEMs to update and revise their designs, with designers looking for faster turn-around times and shorter production runs. This also makes the traditional methods of creating artworks and setting up of photo-tooling methods impractical. In addition, the photo-tool method is dependent on environment conditions—requiring good control over temperature and humidity to tra.... Read more

Why are Printed Circuit Board Stackups Important?

08 - Mar - 2017



For the person designing a Printed Circuit Board (PCB), its stackup is an important factor as this determines the EMC performance of the product. With a good stackup, radiation from loops on a PCB and the cables a.... Read more

Why You Need DFM Checks for PCBs

14 - Feb - 2017

Why DFM CheckFor anything manufactured, Design For Manufacturability (DFM) is an important process. For Printed Circuit Boards (PCBs), DFM is the process of composing the layout topology for mitigating problems that the PCB manufacturing and assembly process could encounter, when manufacturing an electronic system. Although these are two s.... Read more

10 Interesting Facts of PCBs

07 - Feb - 2017

Printed Circuit Boards (PCBs) have a long history. They originated in 1903, when Albert Hanson, the German inventor, had multiple layers of flat coil conductors laminated onto an insulating board. A year later, Thomas Edison experimented with mounting conductors onto linen paper. The technique of electroplating circuit patterns had to wait until 1927, when Charles Durchase patented the proc.... Read more

Epoxy-filled Holes and Via in Pads

01 - Feb - 2017

Via in pad is often needed for putting vias directly in the SMT pads for BGAs and QFNs. There are many situations that you want to use via in pads:

  • For large or fine pitch BGAs they can make routing much easier, or any time when board space is l.... Read more
