TECHNICAL CLEANLINESS STARTS WITH PEM FASTENING SOLUTIONSThe demand for technical cleanliness has risen sharply in recent years. What startedout as a quality control process for the automotive market has become a priorityfor many industries including medical, semiconductor, consumer electronics, andelectric vehicles.As market systems grow in complexity, the components going into them havebecome smaller and more compact. The risk of assembly damage or system failurefrom particle contamination is higher than ever.SEE HOW THE INNOVATIVETHINKING BEHIND PEM FASTENERS CAN TAKEYOU FURTHER.With PEM brand fastening solutions,you get 75 years of industry innovation,global manufacturing locations, high-qualitycatalog and custom parts, and expertsupport to help you go further and solvetomorrow’s most significant challenges.Whatever the application, our fastenerscan provide bigger cost savings, greaterreliability, and critical clean performance.LightweightingReduced Fastener FootprintFaster InstallationSafety Critical ReliabilityClean PerformanceTo ensure technical cleanliness and the exceptional performance of our PEM fastening solutions, PennEngineering uses the most sophisticated cleaning andtesting processes found in the industry.Clean starts here.

DEFINING TECHNICAL CLEANLINESSParticle contamination can have immediate or long-term effects onsystem performance and reliability. While most contamination occursduring manufacturing, it can also happen during material handling,cleaning, packaging, and storage.To achieve the absence of particulate contamination is to achievetechnical cleanliness.In 2005, standards pertaining to technical cleanliness for the automotive industry were introduced. These standards, along with newguidelines defined specifically for other industries, are the foundationfor how PennEngineering measures the technical cleanliness of theirfastening products.FIG. 1: TEST METHOD AS PER VDA 19 PART 1Liquid ExtractionAir ExtractionPressure RinsingUltrasonic TechniquesBlowingInternal RinsingAgitationPerfusionAnalytical FiltrationCLEAN STANDARDSPEM fastening solutions are compliant with the following industryand international standards for technical cleanliness:VDA 19 Part 1 - Inspection of Technical CleanlinessDescribes the inspection methods and conditions that determineand quantify particulate contamination.

PEM CLEAN LABThe technical cleanliness of a component ensures its quality and abilityto contribute to the long lifespan of a product. Even the smallestparticle contamination can put performance at risk.Launched in 2020, the new PEM Clean Lab provides comprehensivecleaning and testing capabilities using the most advanced equipmentin the industry.Clean Lab operations give us the ability to achieve technicalcleanliness of PEM fastening products in accordance withcustomer specifications and ISO 16232 and VDA volume19 standards.ProcessingExtraction – Filtration – Drying and WeighingOur extraction system provides thorough particle analysisof components, suitable for very small and small sizes(up to 30 cm). An innovative alternative to reducingmembrane drying time by nearly 90% compared toconventional membrane preparation.Cleanliness AnalysisReliable – Reproducible – Documented ResultsComplete system for visual inspection and standardized analysis ofparticle sizes 5/15/35 µm. Fully automatic, allowing for higher samplingrate. Led-/POL-lighting capability for faster, more precise detection ofmetallic and non-metallic particles from 5 µm.

MEET YOUR CLEAN REQUIREMENTS WITH PEM FASTENING SOLUTIONSOur portfolio of innovative PEM fastening solutions is one of the largest and most diverse you can find. In addition to meeting theclean requirements that many of today’s industries demand, our fasteners can provide significant value and cost savings to yourmost complex applications.Blind Nut and Standoff RangeProtects internal components fromintrusion of screws and will containparticles when mating screw is notremoved after final assembly.Microproduct RangemicroPEM TackSert pins and fastenersare easy to install and ideal for highlycompact consumer electronicsapplications.Stud RangeMost commonly used in busbarassemblies, the forming manufacturingprocess of our stud range reduces therisk of contamination.Self-Clinching Spinning Nut RangePEM SCN Spinning Clinch Nutsminimize the number of parts inan assembly, reducing risk ofcontamination from loose hardware.Nut RangePEM S Nuts are self-clinching andprovide load-bearing threads in thinsteel or aluminum sheets with highpushout and torque-out resistance.SMTSO Nut and Standoff RangeMount on PC boards in the samemanner and at the same time asother surface mount components,reducing handling and risk ofboard damage.
