DOMESTIC RIGID TECHNICAL CAPABILITIES SUMMARY

SPECIAL EQUIPMENT:                                                                                                                                                                                    

·         CAD/CAM (DRC & DFM)- Includes 3 stations – Barco Cam Software  (includes Laser Plotter).

·         Impedance (TDR) Testing (See Electrical Test Methods)

·         Hi-Pot (High VAC & VDC) Testing, Insulation Resistance Testing (See Electrical Test Methods)

·         Plasma & Permanganate Resin Desmear plus Etchback Processes (QML-31032- MIL Certified).

·         Automated Optical Inspection (AOI) for Photo-tooling & Inner Layers.

·         Vacuum &/or Hydraulic Presses for Multilayer Laminating & Heatsink Bonding.

·         Scoring/V-Groove- Standard & Skip Score with controlled web thickness (Provide a .015 minimum/preferred .020 clearance (Keep-out Area) from edge of board to any conductive feature).  

SCREENING AND SOLDERMASKS:

·         Carbon Conductive Ink

·         Screened Legends (Thermal & LPI-Various Colors)

·         Via Protection– Cover/Tent, Plug, or Fill

·         Liquid Photo-Imageable (LPI) Solder Mask (typical thickness=.001-2 wet-as applied & .0003 (at conductor knee) -.0008 (on conductor surface) dry-minimum after cure). Min Dam Width=.003 in.008 space. Minimum Dam Width Registration +/-.0025".

 

TYPES OF PLATING & FINISHES (ALL FOR MIL APPLICATIONS @ CERTIFIED CONTROLLED THICKNESSES:

·         Deep Nickel/Gold Plating (NiAu) Pre-Etch or Post-Etch (requires tie lines & tie bars) or Nickel/Gold Tabs (Type II, Grade C)

·         Copper Edge Plating with HASL, ENIG or IS Finish

·         Pattern Plating Acid Copper (Cu) Typically .001” thick in the hole & .0012” on the surface (see details below)

·         ENIG= Electroless Nickel (Ni) / Immersion Gold (Au)

·         IS= Immersion Silver (Ag)

·         HASL= Vertical and Horizontal Hot Air Solder Leveling (typical  solder thickness .0001 for flat SMD pads)

·         HAL= Hot Air  Leveled (Lead-Free Solder)

 

 

 TECHNOLOGY & TOLERANCES (SEE DOMESTIC TECHNOLOGY ROADMAP FOR MORE INFORMATION):                                                                                                                                                                                                                     

·         Drilled Hole Size (DHS): Smallest= .0079” (20mm);   Largest= .2559” (6.50mm).  Larger sized holes are routed.

·         Finished Hole Size (FHS): Smallest with plating </=.005

·         Hole Location: 1st : to Datum .003" TIR (Total Indicated Run-out). DTP (Dia about True Pos) Lev. A=.010, Lev. B=.008, Lev. C=.006

·         Conductor (Line/Trace) Width & Space: Minimum Conductors .004"  Minimum Spacing based on .004 Conductor .004"@Half oz. Cu.; .006"@ 1oz. Cu); .009@2 oz. cu. Special- Any widths narrower or starting with thicker copper foils than shown here. Important: Unless advised otherwise, we may modify all or some conductive features for etch allowance (adding typically .001/side of conductor per oz of foil) to provide conductor widths &/or spaces as may be specified or to replicate design features.

·         Aspect Ratio: Level C=9:1 & up

·         Thru Hole Copper Plating Thickness: Minimum =.0008, Typical Average =.001; Higher Depositions As Specified.

·         Minimum Land Requirement for 1-oz Cu & </= 8-layers is maximum drill diameter + 2 minimum annular rings + .010 (Level B)

·         Dimensional Tolerances for Finished Piece/Array: Typical Routed +/- .005; Scored +/- .010; Tighter Tolerances upon Request.

·         Photo-tool Registration Tolerance, Front to Back: Standard +/- .003; Tighter Tolerances upon Request.

·         Thickness Tolerance (Laminate/Material/Overall): Standard = .032 +/- .005; .062 +/- .006; .093 +/- .009; Special = any tolerance < standard (as determined by board specifics). Note: For thin laminate (cores) thicknesses are for dielectric only (foil is added on).

·         Copper Foil Weight (to be specified for all one-sided PCB’s & all inner layers): Minimum thickness (after processing); Standard 1/2 ounce (.0005 thk), 1 ounce (.0010 thk) & 2 ounce (.0022 thk) (QML-31032- up to 2-oz). Note: Nominal thickness for 1 oz. foil is .00135 before processing. All other copper foil weights ( <1/2 ounce - > 2 ounce) are considered Special.

·         Copper Surface Thickness after plating (to be specified as the total copper thickness for all two sided & multilayer outer layers). Processing for thru-hole plating will typically remove a minimum of .0002 of the starting copper foil wt. Pattern Thru-hole Plating will typically deposit .001 of copper in the hole & .0012 of copper on the surface. Specification call out should be for total surface copper thickness minimum of .0013 (1/2 oz base) or .0018 (1 oz base) or .003 (2 oz base) or .0042 (3 oz base) on external conductors with a tolerance total of conductor width and/or thickness reduction due to imperfections equaling 20% maximum for Class 2 and 3 or 30% maximum for Class 1. Designs should also account for conductor width tolerances based on starting foil weight and Design Levels A, B or C (Note: Philway has High Technology Capability to Design Level C applications).

·         Bow and Twist: Standard 1.5%, SMT 0.75% Maximum.

MIL-PRF-31032 Capabilities Include: GF, GI & GM Base Materials with .005 Conductor & Spacing Widths. Up to 15 Layer Construction for all listed Base Material Types (Higher layer counts are available). Note: See DSCC Website for complete QML Capabilities Listing.
