Poll: Businesses are Wanting In-House Conduct Circuit Board Prototyping

Polling of printed circuit board (PCB) designers and makers, electrical engineers, OEMs and others excited about 3D-printed PCBs and circuits reveals that there is certainly escalating demand for in-house prototyping for research and product development. The desire is extremely keen amongst firms that spend as much or more than $100,000 per year for prototyping assistance.

Of the in excess of 975 participants – standing for 31 industries and disciplines and 25 nations around the world – getting involved in the investigation directed by Nano Dimension Ltd., 70 % expend as much as $50,000 and 14 percent pointed out they spend more than $50,000 each year on circuit card prototyping. Also, a full 16 percent, or 142 respondents, are paying in excess of $100,000 to contracted-out prototyping suppliers every year. Most answerers clarified that the prototyping costs were excessive because they need the fabrication of complicated, multi-layer circuit cards – with 66 % of those interviewed indicating their designs include multiple layers.

While upwards of 9 in 10 participants explained their establishments rely upon off-site prototyping factories currently, nearly two in three claimed they think their intellectual property (IP) is in jeopardy whenever they do it. Most say they really wish ways for printing their own circuit cards inside.

“Designers and technical engineers definitely prefer shorter turn-around times and lower risk every time dispatching their design information for prototyping,” said Simon Fried, Nano Dimension’s CBO and a company co-founder. “But with most of the manufacturing houses in China, timeliness is rarely an option. The fact is that, sometimes they end up with circuit boards for production that are not enhanced as much as they want on account of the long lead times. And sending out designs generally raises the chances which the IP could be duplicated or robbed.”

Even though the prototyping houses are fully known partners, the time constraints involved with outsourcing can stifle creativity. Lots of designers rely upon “safe” circuit board designs instead of exploring innovative new ideas in case they may result in multiple iterations – and additional delays – with the prototyping facility.

“With progressive alternatives just like Nano Dimension’s DragonFly 2020 3D Printer, the electronics can finally catch up to other forms of manufacturing that have benefited from additive manufacturing,” Fried said. “Our survey demonstrates the demand is there, and the market is ready for 3D-printed circuit boards that can be produced on-site soon and cost-effectively.”

Nano Dimension, a frontrunner in 3D printed electronics, hosts the survey on its website. Respondents stand for industries covering everything from electronic circuit board makers and OEMs to engineering, defense, manufacturing, aerospace, electronics, medical, detectors and wearables, telecommunications, energy and the like.

Rigid-flex Printed Circuit Board Design Covers Wearable Healthcare Gadget Obstacles

Rigid-flex Printed Circuit Board Design Covers Wearable Healthcare Gadget Obstacles


The majority of PC boards in the world today are basically inflexible plates to connect circuitry. But, that is changing rapidly; the need for flexible circuit boards (or flexible circuits) is rapidly escalating mostly due to the flourishing wearable product industry. Probably the largest segment of that market is the medical care industry where wearable gadgets will be employed to collect all varieties of biological info for examination and study, and also individual health use. Undoubtedly wearables can be obtained to watch heart rhythm, blood pressure, glucose, ECG, muscle movement, and even more.

The wearable devices present a number of problems for circuit card designers that rigid boards do not. Here are several of such problems and what designers can perform to alleviate them.

Three-dimensional Design

While every single circuit board is actually 3 dimensional, flexible circuits enable the entire assy to be bent and folded to conform to the package that the merchandise requires. The flex circuitry is collapsed to ensure the rigid PCBs fit into the item package, taking up minimal space.
There are lots more to the design, hence the extra challenges, than simply connecting the rigid boards. Bends should be precisely designed so boards line up where they’re intended to mount, while not putting stress on the connection points. Up until recently, engineers actually used “paper doll” models to simulate the circuit card assy. Right now, design tools are available providing 3D modelling of the rigid-flex assembly, which allows faster design and a lot greater exactness.

Tiny Products and Compacted Circuits

By definition, wearable products should be tiny and unobtrusive. Up to now, a medical “wearable” such as a Holter pulse rate monitor included a fairly large exterior device with a neck strap or belt mount. The recent wearables are small and install straight away to the sufferer with no or very few external wires. They obtain an assortment of info and can even process several analyses.

An unobtrusive device mounting straight to the sufferer demands flex circuitry and really dense layouts. On top of that, the board shapes in many cases are spherical or maybe more unusual shapes, demanding creative placement and routing. For these kinds of tiny and densely-packed boards, a electronic circuit board tool that’s enhanced for rigid-flex designs helps to make addressing unconventional shapes more convenient.
Stackup Design is a must

The stackup – the map of the electronic circuit board layers – is very important when you use rigid-flex techniques. If possible, your PCB design software has the capacity to design your stackup including both the rigid and flexible parts of the assy. As mentioned earlier, the layout of the bending area needs to be designed to reduce the stresses on the traces and pads.
One of the primary obstacles with rigid-flex designs is qualifying several producers. After the design is finished, every aspect of the design have to be communicated to the board fabricator therefore it will be appropriately produced. Having said that, the best practice is to choose one or more producers at the beginning of the design and collaborate with them to be certain your design fits their assembly demands as the design gets better. Participating with manufacturers is simplified by utilizing standards. In such a case, IPC-2223 is the vehicle for making contact with your fabricators.

As soon as the design is completed, the data package is required to be assembled to hand-off to be made. Although Gerber remains utilized for standard PCBs in certain enterprises, with regards to the difficulties of rigid-flex, it is strongly advised by both PCB program providers as well as fabricators that a more intelligent data exchange format be employed. The two most famous intelligent formats are ODG++ (version 7 or higner) as well as IPC-2581, both of which precisely specify layer standards.
