Screw-Terminal Construction

General Manufacturing Process
• Winding Wind anode, cathode, papers together with connecting tabs
• Decking Attach winding to terminals on deck
• Impregnation Impregnate winding with electrolyte
• Assembly Fit winding and deck to can and seal
• Ageing Repair oxide damage from slitting and winding
• Testing Measure capacitance, ESR, Z and leakage current
• Finishing Fit external insulation and marking
• Packing Pack ready for shipping
• Slitting Cut foil to the needed width

Aluminium Oxide Dielectric
• Thicker dielectric reduces maximum capacitance potential
• Dielectric thickness determines voltage rating

Key Parameters
for design

Anode Foil (Etching)
• Electrochemical tunnel “Etching” of 99.99% aluminum
• Tunnel initiation strongly influenced by impurities
• Tunnel diameter 1um - 2um across
• Tunnel length 15um - 50um long
• Density 10 - 25 million tunnels per cm2
• Foil gains 50 to 100 (actual area / plain surface area)
The disadvantage of Surface “Etching” is the
reduction of the capacitors ability to withstand HIGH
DC currents

• High conductivity, neutral pH
– Acid + Base -> Salt
• Wide operational temperature range
– Stay conductive across range
• Provides ability to reform oxide
– Controlled level of water
• Compatibility with paper and deck material
– Hydrogen gas absorber
• Low flammability, low toxicity
Electrolyte Composition

Separator Papers
• Materials (pulp)
– Kraft, manila, esparto, hemp
– Combinations of pulp are often used
• Properties
– Thickness 12µm to 90µm
– Density 0.3 to 0.8 g/cm3, uniform density, minimum
pinholes
– Simplex – single type of paper
– Duplex – two papers joined together
• Usage
– 1 to 3 papers used between anode and cathode
– Up to 5 actual layers when duplex paper used
