• Resin Containment
  PACO•VIA Resin Blocking Film contains the resin within the via barrel eliminating the need for secondary processing to remove cured resin from the panel surface.
• Barrel Fill
  PACO•VIA Resin Blocking Film allows the liquid resin to essentially fill the via Barrel.
• Contain Resin Squeeze-out
  PACO•VIA contains resin squeeze-out like traditional release films while offering superior copper surface buffering from damaged Separator Plates.
• Equalization of Pressure Throughout the Pressure Load
  The PACOPADS component of the PACO•VIA System ensures complete barrel fill, and controlled Dielectric Thickness. PACOPADS eliminate air voids, inner-layer slippage and white corners or edges. PACOPADS also reduce image and glass cloth Transfer, and alleviate the potential of low-pressure prepreg Blisters. See PACOPADS Product Information Bulletin.

• Three engineered Grades to fit all sequential lamination demands.
• Choice of PACOPADS Pressure Equalizing Press Pads designed to suit all lamination process parameters.
• Operating temperature of 425°F / 218°C for up to 4 hours.
• Proven worldwide performance since 1996.
• Essentially inert, no out-gassing, plate residue, interlaminate adhesion
  influence, no vacuum system contamination.
• Environmentally friendly: no chrome-depleting chemicals, no Flourines.

• The PACO•VIA System is designed to contain the resin flow within Blind Via Holes(onto adjacent copper-carrying layers) and to fill buried Via Barrels, under a wide range of Lamination Pressures (175-350 psi/12-24 kg/cm2), Hole Diameters (.004 to .040"/0.1 to 1.0mm), Heat Rises and Prepreg types.
• The PACO•VIA System performs effectively well in Hydraulic and Hydraulic Vacuum-assist
  as well as with both stainless steel, and aluminum Separator Plates. Steel is preferred.
• The PACO•VIA System is suitable for all resin system types when laminated within the listed temperature constraints.
