PACO•VIA™ 3000:

A BLIND VIA HOLE LAMINATING FILM

OVERVIEW

PACO•VIA™ 3000 is a two-sided release film designed to be part of a Two-Component System (PACO•VIA™ 3000 and PACOPADS™) as a performance-driven line of High-Temperature, Resin-Blocking Release Films. The PACO•VIA™ 3000 System is specifically engineered to enhance sequential lamination of Buried and Blind Via designed rigid printed Circuit Boards.

LAMINATION PROCESS ADVANTAGES

• Resin Containment: PACO•VIA™ 3000 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™ 3000 Resin Blocking Film allows the liquid resin to essentially fill the via Barrel
• Contain Resin Squeeze-out: PACO•VIA™ 3000 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™ 3000 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

FEATURES

• Two 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
• Essentially inert, no out-gassing, plate residue, interlaminate adhesion influence, no vacuum system contamination
• Environmentally friendly: no chrome-depleting chemicals, no Fluorine’s
• The PACO•VIA™ 3000 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™ 3000 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™ 3000 System is suitable for all resin system types when laminated within the listed temperature constraints
