Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Cincinnati Inc., ORNL working on machine that 3D prints HUGE parts; Local Motors plans to use the tech to 3D print electric car

By Mike Foley, Designfax

Cincinnati Inc., a metal fabrication juggernaut for more than 100 years, has teamed up with the Department of Energy's Oak Ridge National Laboratory (ORNL) to develop and commercialize a new large-scale additive manufacturing system capable of printing huge polymer components -- much, much faster than many current systems can build small parts.

Hmmm ... how can that be?

Well, according to Lonnie Love, Ph.D., group leader of ORNL's Manufacturing Systems Research Group, the secret is in the materials and the delivery.

Love says that the new machine has an 8 ft x 8 ft x 8 ft build envelope and is scalable, with the biggest near-term future platform envisioned to be 20 ft x 10 ft x 8 ft. That is huge, when you consider that a 3 ft3 build envelope is considered large these days.

The proposed large-part additive manufacturing machine from Cincinnati Inc.

 

 

But how can the material print and cure faster? Now that is interesting. Love says that the answer is two-fold.

First, the machine prints with a big nozzle, so more material is heated and extruded (but not anywhere near as precisely). Love says that a typical fused-deposition modeling (FDM) machine has a 0.020-in. nozzle. The ORNL machine uses a 0.3-inch one. The material comes out looking like, and this is a really accurate description, something you'd see when looking at your piped-icing-decorated birthday cake (see Local Motors video below). No one said this machine is fast and accurate, at least when it comes to the printing part.

The other difference is the material. Instead of using a line of (plastic or ABS) filament like most 3D printers use, the ORNL machine uses a mixed plastic-and-carbon-fiber material that comes in pellets. The carbon fiber greatly reinforces the material, so it can be formed lighter and stronger. But unlike traditional FDM, Love says that this material enables part stability at room temperature. "There is no oven," he says, so parts cure extremely fast, even if they are large.

A prototype of the large-scale additive machine is in development using the chassis and drives of Cincinnati's gantry-style laser cutting system as the base, with plans to incorporate a high-speed cutting tool, pellet feed mechanism, and control software for additional capability.

Cincinnati's experience in designing, making, and controlling large-scale manufacturing systems, as well as its long working relationship with ORNL, led to the partnership.

"As one of the oldest U.S. machine tool makers, with continuous operation since 1898, we view this as an opportunity to start a new chapter in our history," says Andrew Jamison, CEO of Cincinnati Inc. "Over the years, we've supplied more than 40 metal working machine tools to Oak Ridge and its subcontractors. Now, working together, we intend to lead the world in big-area additive manufacturing for prototyping and production."

According to Love, the capability of this machine to produce tooling -- and not particularly standardized "parts" -- is its big breakthrough. "We have already made and tested large metal forming tools for the aerospace industry," says Love. "It will revolutionize U.S. tooling. We've made custom furniture and are working with Local Motors on customized printed electric vehicles." Love says the project was initially an internal Lockheed Martin program. They partnered with ORNL last year, and ORNL has funded it internally for a year. This year the goal is transitioning to a commercial product with Cincinnati Inc.

So rather than printing "parts" (be they big or small) like most of us think of when we think of 3D printing, this printer can also print the base materials to create things like big molds or dies.

"But I thought you said this process isn't particularly accurate," you are probably thinking, "so how can you use it for tooling?" Well, that is where another process comes in: subtractive manufacturing (or milling). Remember that Cincinnati said that the machine can incorporate a high-speed cutting tool?

A look into the Local Motors project can shed a little more light on this. Alex Fiechter, head of R&D and community management at Local Motors, explains (in the video below) that the large ORNL 3D-printing machine also contains a machining head for material removal, so that once the 3D part is printed in the rough it can be machined to needed tolerance/specifications.

Local Motors, a pioneer in the online design and hardware co-creation market and known for creating a really cool customizable car called the Rally Fighter, has agreed to build a 3D-printed electric car for the Association For Manufacturing Technology to be featured at the upcoming International Manufacturing Technology Show (IMTS) 2014 in Chicago, IL, September 8-13, 2014.

"We're printing the body and frame of the vehicle, along with seats and anything else that we can," says James Earle, advanced manufacturing engineer at Local Motors. ... The printed parts will all be one piece."

"We won't be printing the drive train components or any other electrical systems," says Earle.

A look at a video update that Local Motors posted recently gives some insight into what is going on with their IMTS car and the ORNL printer. In it, Fiechter explains how the printer first lays down the basic form of the polymer/carbon fiber part quickly and then the part is machined out (that's the subtractive part) to produce a finished result. Local Motors also says that it is investigating using ULTEM with carbon as one possible material and ABS with carbon as another.

Using this method, both standard "parts" and tooling can be created.

"We're using chopped fiber that is integrated into the plastic pellets we buy (we don't add it ourselves)," says Earle. "For FDM parts (fused deposition modeling, how we're printing the car), it's relatively new. We're one of only a few using carbon fiber to reinforce printed plastic at this scale, but there are a lot of people interested in the idea and studying it."

Earle says that they probably won't be 3D printing metal parts for the IMTS car, but the project engineers "have looked into printing custom fasteners that we could incorporate into the car as we print."

"For our purposes, we want to print a functional car," says Earle. "That means printing 'usable' parts. There is a lot of interest in the machine from other companies for use in creating dies for tooling purposes, e.g. to form sheet metal, but Local Motors wants the car to be printed in one piece. It's possible we may, in the future, use the printer to create molds for door panels or something, but initially no."
