thing to do with electronics manufac- turing. Those really allowed to us to bring all of our creativity to the table,” says Trabold. The focus is always to improve ergonomics and make it easy for workers to do their jobs. The goal of one project was to automate han- dling processes that involved material packages weighing 55 lb (25 kg) or more that needed to be managed within the man- ufacturing area, which also required a logistics connection between a regular manufactur- ing environment and a clean- room.


Trabold’s team had the idea of using roller conveyors

with Smartmotor control. Heavy- duty turning stations with hoists for redirecting the material packages were a key component of this automation design. Docking stations


transferred the packages from the industrial trucks to the handling sys- tem. The highlight, however, was an automatic pass-through airlock in the wall for moving the packages from the production facility into the cleanroom. SEHO’s single-source


philosophy has another great benefit for users. All compo- nents of the production line, including SEHO’s soldering and AOI systems, are designed to harmonize per- fectly in their technology and in the production process. “We love what we do,

and that’s why we’re good at it,” says Simone Neukirch, an electronics specialist in the team. Trabold adds, “Produc -

Leak Testing Hermetically Sealed


used, there are several safety precau- tions that must be followed. Discon - nect the air supply and depressurize all air lines connected to the fixture before installation or servicing. Operate within the manufacturer’s specified pressure, temperature, air quality, and other conditions listed in the manual. Installation, service and cali-


bration of the instrument or fixture must be performed by knowledgeable personnel who understand how pneumatic and electronic products are to be handled. There are several steps to eval-


uate before selecting a leak testing instrument. When a quality engineer is tasked with determining a new component’s specifications, produc- tion process, and testing procedures, he or she should first consider the costs and benefits of leak testing that specific part. If leak testing is determined to


be necessary for the manufactured component, the next step is to identi- fy the potential leak paths. Common areas can include welds, seals, micro- cracks, and pinholes. Most leaks are so small they are not visible to the human eye, which is why precise, data-rich testing results are neces- sary. After potential leak paths are identified, engineers establish a leak rate reject limit for the application based on theoretical calculations, industry specifications, and compar- isons to specs of similar existing applications. One of the most common meth-


ods used to establish a reject level is to measure leak rates on customer- returned products. Next, the manu- facturing engineer can work with a leak testing engineer to determine the most appropriate leak testing method for the application, whether that be differential pressure decay, tracer gas, or sealed component ingress leak testing. Finally, based on the company’s


budget, application specifications, determined testing method, and service requirements, the manufac- turer can select the most suitable leak testing company and testing instrument to fit their needs. Contact: ATEQ Corp., 35980
