Pitman, NJ — Precision Assembly Technologies (PAT), based in Bo- hemia, New York, was seeking a sys- tem that could dispense specific sol- der beads within a component, as well as placing the die into position within a housing. Essemtec’s FOX2 multifunction


combined pick-and-place and dis- pensing system provided the solu- tion. The new FOX2 combines jet-

about the possibility of post-assem- bly failures in the field. Thomas Gulotta, president,


PAT, believed the best way to solve the failure issue was to bring the pro- duction of the component in-house and have complete control of the process. The assembly of the stacked de-


vice was something that the Es- semtec FOX2 was suited for, with the ability to perform the two sol- der paste dispensing func- tions, as well as the placement of the die in the housing. After deciding to bring the assembly in-house with the installation and implementation of the Es- semtec system, PAT was able to gain total control of the as- sembly process. “The addition of the Es-

The compo- nent was a silicon die within a hous- ing that had a failure rate of approx- imately 20 percent upon receipt and yielded only 50 percent after potting and final testing of the assembly. PAT was absorbing the cost of the failed part, but was frustrated by the high failure rate and concerned


semtec FOX2 allowed us to produce 500 components per day with less than a one per- cent failure rate, all on a so- phisticated but easy-to-use platform,” says Gulotta. “The dispensing of the solder beads and placement of the die are now handled by the FOX2 and we are extremely happy with the results.” PAT is an AS9100-certified

ESCATEC Perfects Mfg Protocols During COVID-19 Lockdown


Heerburgg, Switzerland — During the global COVID-19 lockdown, only essential items were permitted to be manufactured in Malaysia, such as ventilator and respirator parts. ES- CATEC builds these in Penang and worked closely with Malaysian au- thorities to implement working pro- tocols, enabling these critical items to be produced. ESCATEC’s stringent im-


plementation of hygiene and so- cial distancing measures, which preceded government mandated requirements, has meant that it is one of the first manufacturing companies in Malaysia to be al- lowed to resume normal opera- tions of non-essential products as lockdown measures ease. “Having common working


procedures and protocols for both our medical and non-med- ical manufacturing facilities meant that we could rapidly re- ceive approval to reopen pro- duction of non-medical de- vices,” says ESCATEC group managing director Markus Walther. “We have been in reg- ular contact with all parts of our supply chains to keep them informed so that they were ready to support us when we resumed full production. This enables us to provide precise status information to our customers on their orders, which is unusual in these uncertain times.” An aspect of uncertainty for


customers of manufactured goods as products start shipping again has been the China/U.S. trade war. This has meant that items made in China


have been targeted with import du- ties. Strong compliance understand- ing allowed ESCATEC’s export team in Malaysia to prepare certificates of origin to ensure that there is no in- terruption to shipments or unneces- sary tariff costs.

Heraeus and RWTH Aachen Develop Artificial Synapses


Hanau, Germany — Researchers from the technology group Heraeus and the Jülich Aachen Research Al- liance (JARA) have discovered how the switching properties of artificial synapses can be specifically influ- enced.


Memristors, electrical compo-


nents that can be switched between a low and high value — a sort of resist- ance with memory — are considered a promising alternative to conven- tional components in computer chips. In principle, they function like a synapse of the biological nervous sys- tem and also get by with extremely little electricity. “Memristive elements are re-


garded as ideal candidates for neuro- inspired computers modeled on the brain, which are arousing great in- terest in connection with deep learn- ing and AI,” says Dr. Ilia Valov of the Peter Grünberg Institute (PGI-7) at Research Center Jülich. The components with which the


research team has conducted system- atic experiments consist of an ultra- thin, amorphous, fused-silica layer (silicon dioxide) between a platinum and copper electrode. The purity of the central oxide


layer is the decisive factor. The re- searchers have deliberately intro- duced foreign atoms into the 99.9 percent pure (8N) silicon dioxide. “By


introducing foreign atoms, we influ- ence the solubility and transport properties of the thin oxide layers,” says Dr. Christian Neumann, Her- aeus Technology Group. This effect had previously been


unnoticed by experts. It can be used specifically for the design of memris- tic systems, similar to the doping of semiconductors in information tech- nology. The specifically doped glasses were developed and manufactured by fused-silica specialist Heraeus Conamic, which also holds the patent for the materials. Memristive elements behave in


a similar way to their biological role model. The brain’s ability to learn and remember information is largely due to the fact that the connections


between nerve cells become stronger when they are used more frequently. In artificial synapses, conductivi-


ty increases with the number of in- coming voltage pulses. The changes can also be reversed by applying volt- age pulses of opposite polarity. The higher the doping (the number of for- eign atoms in the oxide layer), the slower the resistance of the elements changes with the number of incoming voltage pulses and the more stable the


resistance remains. Contact: Heraeus, Inc.,
