MAY 2019 I PCB007 MAGAZINE 63 ability routines are vital and can be the defin- ing factor between failure and success, or even worse, life or death. If traceability and limita- tion of consequential cost are important for you, I recommend staying tuned to the devel- opment of IPC-1782 with its new revision be- ing developed right now. From my perspective, this standard will give us an important tool, especially if you link it up to IPC-2581 and the CircuitData specification language. All of this is currently under development and will give the future an important tool to control your traceability needs. Stay tuned; we will come back with further news on this topic. For El- matica, traceability is not a buzzword; it's one of our three core values. PCB007 Jan Pedersen is a senior technical advisor at Elmatica.

In many industries, there are regulatory com- pliance requirements enforced by the country the electronic device is being employed. The most obvious is in the defense industry where traceability must show where all critical com- ponents are made. When procuring printed circuits or materials to the defense industry, there is no such thing as assuming or relying on questionable interpretations. There are no options for shortcuts whether your supplier follows the regulations or not. You must know the country of origin down to the printed cir- cuit or material level of your products, and the bill of materials (BOM) should encompass a country of origin for every article. Traceability: Not Just a Buzzword In the medical industry, we have regulato- ry requirements from authorities such as FDA and EU Medical Device Directive. Good trace- Hiroshima University, the National Institute of Infor- mation and Communications Technology, and Panasonic Corporation have developed a terahertz (THz) transceiver that can transmit or receive digital data at 80 Gb/s using the channel 66 defined by the IEEE Standard 802.15.3d. The transceiver was implemented using CMOS technology, which would have a great advantage for volume production. The THz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications. Published in October of 2017, IEEE Stan- dard 802.15.3d defines the use of the lower THz frequency range be- tween 252–325 GHz as high-speed wireless communication channels. "We presented a CMOS transmit- ter that could do 105 Gb/s in 2017, but the performance of receivers we developed—or anybody else did for that matter—were way behind for a reason. We can use a technique called power com- bining in transmitters for performance boosting, but the same technique cannot be applied to receivers. An ultra- fast transmitter is useless unless an equally fast receiver is available. We have finally managed to bring the CMOS receiver performance close to 100 Gbit/s," said Professor Minoru Fujishima, Graduate School of Advanced Sciences of Matter, Hiroshima University. "People talk a lot about technological singularity these days…you wouldn't want to have a zero-gravity operation on board a space plane without re- al-time connection with earth sta- tions staffed by medical super-AI and doctors. After all, singularity is a self-fulfilling prophecy…It will be a distant outcome of what we develop today and tomorrow," said Fujishima.
