Automation has swept across the electronics manufacturing industry. Automatic conveyors, pick and place machines, and robotic systems are all working at breakneck speed. The increased rate also means an exponentially higher rate of charge generation and accumulation compared to manual operations, one that cannot be compensated by traditional surface coated anti static packaging. Permanent ESD blister packing from Shanghai Leenol ensures the sustained anti static protection your automated line demands. Read on to discover how:
Consistent Static Dissipation for High-Speed Handling
An automated line operates at speeds of hundreds or thousands of components per minute, where every action of picking, placing, sliding, or vibrating generates static through triboelectric charging. When static dissipating blisters with surface coatings are used on automated lines, the friction between the components and the blister packaging can quickly wear down the topical coating. As the coating wears, static can build up and discharge intermittently in ways that are nearly impossible to trace back.
Permanent ESD blister packing ensures that a dissipative material runs throughout the blister itself-the anti-static property doesn’t wear off over time regardless of how many cycles a blister packaging part goes through. Whether your component is sliding on the blister's surface ten times or ten thousand times, the blister maintains a safe surface resistivity of between 10¹⁰ and 10¹² ohms, preventing unexpected static buildup and allowing automated machinery to operate at full speed. When automated lines are running 24/7, elimination of this single variability increases overall process stability.
Component Protection During Automated Transport
With a number of transport stages, including from tray to conveyor, conveyor to blister pack, and blister pack to shipping container, your components are at risk of electrostatic discharge when they move throughout an automated line. Blister packs with a topical coating fail to adequately protect components when the coating itself can be scratched or abraded during transport on the automated line.
When you choose permanent ESD blister packing, the blister material itself remains dissipative even when scratched, abraded, or cleaned. The components will be supported by a static dissipative surface at every stage, including sensitive MEMS, RF components, and bare dies. Shang Hai Leenol provides ESD blisters that meet theIEC61340-5-1standard and are produced under ISO 9001, so that every blister pack maintains the level of protection that the first one delivered.
Elimination of Coating Failure in High-Humidity Environments
While some automated electronics manufacturing lines are kept at low humidity levels to prevent the damaging corrosion associated with humidity, this is often to the detriment of any topical anti-static treatment. At low humidity levels, some coating treatments dry out and crack or lose their anti-static properties entirely. Permanent ESD blisters, on the other hand, remain effective regardless of the humidity of the room. This is crucial when considering automated lines used at semiconductor fabs, data center hardware assembly facilities, and automotive electronics assembly sites where humidity is tightly controlled.
Repeatable Performance for Automated Inspection and Traceability
Vision systems, barcode readers, and RFID scanners are commonly used on modern automated assembly lines to confirm that each component is present and placed correctly as well as to check for quality and other issues. If the surface characteristics of the blister packaging change or vary widely as with topical coating systems which are difficult to test for consistent performance across each component part, your automated inspection and traceability will be severely hampered. Consistent performance between each blister packing piece allows for correct optical scanning and read accuracy from RFID systems. The blister packaging itself will add value to your automated inspection and traceability process instead of being a barrier to it.
Shanghai Leenol offers custom blister packaging that allows you to design specific cavities, dividers, and marking features without affecting the permanent ESD properties of the blister packaging. Leenol can fulfill your user design orders with short turnaround times, enabling you to optimize blister packing geometry for automated handling and inspection.
