Design Preparation: <\/strong>Use CAD software to define circuit patterns, ensuring trace widths and spacing comply with thick copper (\u22653 oz\/ft\u00b2) current-carrying requirements.<\/p>\n\n\n\n<p><strong>2. Material Selection<\/strong>: Choose substrates with high thermal stability (e.g., FR-4, polyimide) and copper foils tailored to target thickness (4 oz\/ft\u00b2 to 20 oz\/ft\u00b2).<\/p>\n\n\n\n<p><strong>3. Copper Deposition<\/strong>: Apply electroplating or etched-foil processes to achieve uniform copper layers. Thick copper requires controlled plating currents to avoid voids or uneven distribution.<\/p>\n\n\n\n<p><strong>4. Pattern Etching<\/strong>: Use alkaline or acidic etchants to remove excess copper. Thick copper demands longer etching times and specialized chemistry to prevent undercutting.<\/p>\n\n\n\n<p><strong>5. Lamination<\/strong>: Stack prepreg layers and copper clads under high temperature\/pressure. Thick copper boards may require sequential lamination to manage resin flow and avoid delamination.<\/p>\n\n\n\n<p><strong>6. Drilling<\/strong>: Machine-drill via holes using carbide bits. Thick copper boards need slower drill speeds and peck-drilling cycles to prevent bit wear and ensure hole quality.<\/p>\n\n\n\n<p><strong>7. Through-Hole Plating<\/strong>: Deposit copper into drilled vias via electroless or electrolytic plating. Thick copper requires thicker via barrels (\u22651.5 mils) to withstand high current and thermal stress.<\/p>\n\n\n\n<p><strong>8. Solder Mask<\/strong>: Apply epoxy-based solder mask using screen printing or spray coating. Thick copper boards may need adjusted mask thickness to cover raised copper areas.<\/p>\n\n\n\n<p><strong>9. Surface Finish<\/strong>: Apply finishes like HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservative) for solderability and corrosion resistance.<\/p>\n\n\n\n<p><strong>10. Testing<\/strong>: Perform electrical continuity tests, thermal cycling, and impedance checks to validate performance under high-current and high-temperature conditions.<\/p>\n\n\n\n<h2
