ITW Paktron Capacitors - Ultra Low ESR Multilayer Polymer Film Capacitors

Manufacturing System
Go to Interleaf® Material Advantage

From experience in film and MLC capacitors, Paktron determined that many developments could be expected in the field of pre-fabricated dielectrics for electrostatic capacitors.

These developments would include ultra-thin films, high-temperature and flame retardant films, and high K materials. What was needed was a manufacturing system that would cost effectively advance the technology of the day and be compatible with emerging dielectric technology as it became available.

A key consideration in the development was to use proven processes and materials which could be integrated into an easily operated and maintained manufacturing system.

The Interleaf® Technology Manufacturing System presented here is geared for the manufacturing goals of the 21st century. This system is a major advancement in manufacturing technology that provides an extremely efficient and cost effective alternative to other film capacitor production.

Material Advantages

No margin metallization. Vacuum plating is simplified by eliminating margin masking.
Reduced metallized film inventory. Few widths are needed to produce a large variety of sizes.
Larger film supply rolls. Wider webs and larger rolls provide film at lower cost.
Smaller precise margins. The ratio of electrified to structural film usage is maximized.
Aluminum terminals. Similar metal contacts, higher conductivity and lower costs are achieved.
Lower spray metal usage. Compact sticks in rectangular frames effeciently capture spray metal.
Higher effective dielectric constant. High temperature/pressure stick cure excludes low K air.
Capacitor blocks cut to value. Higher yields, tighter distributions and lower material usage are assured.
Self encasement. Expensive structural material such as boxes and epoxy are not required.
No hazardous material. Toxic chemicals and Pb spray are eliminated by design.
