UltraPad™ Press Pads
The Arlon UltraPad™ press pads are a family of high performance, fiberglass reinforced, silicone sheets designed for flex and rigid-flex circuitry lamination. UltraPad press pads provide excellent pressure uniformity with unparalleled consistency and longevity throughout their service life. UltraPad press pads are the most cost effective press pad solution across a wide range of process pressures and temperatures.

UltraPad™ D75 = Arlon part number 55173R062 (General Purpose)
UltraPad™ D70 = Arlon part number 55133R062 (Improved Pressure Uniformity and Long Service Life)
UltraPad™ D65 = Arlon part number 55073R062 (Best Pressure Uniformity for Critical Applications)
UltraPad™ D65 = Arlon part number 51073R031 (Fast Press)
Arlon UltraPad™ is normally sold without a surface treatment. A surface treatment (ST) is available for low tack press pad requirements)
Silicone press pads are specially formulated, reversion
resistant silicone rubber composites designed for hydraulic and
autoclave lamination. They act to distribute pressure in the lamination
of circuit boards, high pressure laminates, laminated plastic, and
electron circuitry. Silicone press pads are available in standard
constructions or high performance construction.
Use of silicone press pad materials eliminates the need for throw-away
pressure
distribution vehicles such as kraft paper, blotter paper, chipboard,
and other nonwoven paper- like pads.
Silicone Rubber Benefits:
• Long service life
• Uniform heat rise – use
after use
• Reduced inventory
• Less handling
|
• No shedding
• Dimensionally stable
• Uniform cushioning –
no hard spots
• Reduced storage
• Faster layup
|
Press pads provide uniform cushioning and precise control over
heat rise. When used as shown, press pads will reduce “white-edges”
and other problems caused by uneven surfaces and inconsistent B-stage
flows.

A typical press pad application for an 18” x 24” B-stage tooling package. The uniform heat
provided by silicone press pads permits more wet time for
the resins to flow, providing strong, reliable bonds
without voids, thus enhancing circuit reliability.
Availability:
