PCB And IC Technologies Meet In The Middle


Surface-mount technology (SMT) is evolving far beyond its roots as a way of assembling packaged chips onto printed circuit boards without through-holes. It is now moving inside packages that will themselves be mounted on PCBs. But SMT for advanced packages isn’t the same as the SMT we’ve been used to. “Many systems include multiple ASICs, a lot of memory, and that's all integrated i... » read more

PCB Design Rules For Wiring And Crosstalk


Today’s electronic devices market demands miniaturized printed circuit boards (PCBs) with a multitude of high-speed functions integrated on a single board. This causes the designers to have traces routed very close to each other to optimize packaging and space. This proximity may cause unintentional coupling of electromagnetic fields, a phenomenon which we know by the name of crosstalk (see f... » read more

Design For Manufacturing Best Practices


Manufacturing issues are one of the top reasons that we see warranty returns and loss of market share in the electronics industry. Issues like supply chain failures and printed circuit board assembly (PCBA) production challenges related to design can lead to irreparable damage to a brand’s reputation. It is therefore critical that companies have a design for manufacturability (DfM) protocol i... » read more

Blog Review: Feb. 12


Complexity is growing by process node, by end application, and in each design. The latest crop of blogs points to just how many dependencies and uncertainties exist today, and what the entire supply chain is doing about them. Mentor's Shivani Joshi digs into various types of constraints in PCBs. Cadence's Neelabh Singh examines the complexities of verifying a lane adapter state machine in... » read more

Power/Performance Bits: Feb. 4


Infrared nanoantenna Researchers at the University of Würzburg built a nanoantenna capable of generating directed infrared light. The Yagi-Uda antenna is the smallest of its type yet created. "Basically, it works in the same way as its big brothers for radio waves ," said René Kullock, a member of the nano-optics team at Würzburg. An AC voltage is applied that causes electrons in the met... » read more

Putting “Design” Back Into Design For Test In PCB Products


Design for manufacturing (DFM) has become a proactive part of the design process, but the same cannot be said for DFT. Whereas “left-shifting” DFM has reduced manufacturing problems, increased yield, reduced scrap levels, and simplified engineering rework, testability-related improvements have stayed flat during that same time. Unfortunately, as assembly costs have come down, and test-relat... » read more

EDA, IP Sales Up 8%


The EDA sector continues to exhibit solid growth, increasing 8% to $2.2262 billion in Q3, up from $2.0937 billion in the same period in 2016, according to the most recent stats from the ESD Alliance Market Statistics Service. The four-quarter moving average was up 11.5%, year over year. While all of the numbers were up, two areas showed extraordinary growth. One involved Japan, which showed ... » read more

Get Ready For In-Mold Electronics


Imagine inserting the electronics into a product without using a printed circuit board, a module, or even a system-in-package. That's the promise of in-mold electronics (IME), a technology that has been around for years, but which is just beginning to see wider adoption. The technology is related to conductive inks and transparent conductive films. The IME manufacturing process is said to pr... » read more

Inside Panel-Level Fan-Out Technology


Semiconductor Engineering sat down to discuss panel-level fan-out packaging technology with Tanja Braun, deputy group manager at the Fraunhofer Institute for Reliability and Microintegration IZM, and Michael Töpper, business development manager at Fraunhofer IZM. Braun is responsible for the Panel Level Packaging Consortium at Fraunhofer IZM, as well as the group manager for assembly and encap... » read more

Industry 4.0 And The Internet Of Manufacturing For PCB Assembly & Fabrication


For years, the PCB manufacturing industry has needed a robust real-time, comprehensive shop-floor communication standard that would include detailed, bidirectional, machine-to-machine communication, as well as shop-floor to IT computerization communication. Now, there is a solution: the Open Manufacturing Language (OML), an open communications specification managed through a community of indust... » read more
