A typical lamination (from Top to Bottom) is as follows: Layer 1 (signal\/power layer, 5OZ copper, carrying the main power signal) \u2192 Layer 2 (ground layer, 35\u03bcm copper, for power - ground return) \u2192 Layer 3 (power layer, 5OZ copper, for the main power - supply loop) \u2192 Layer 4 (power layer, 35\u03bcm copper, for auxiliary power - supply) \u2192 Layer 5 (ground layer, 35\u03bcm copper, for signal - ground return) \u2192 Layer 6 (signal layer, 35\u03bcm copper, for control - signal wiring). The symmetrical lamination design controls warping. The high - copper - thickness layers are suitable for large currents of \u226530A.

The core material selections are as follows:<\/div><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(1) Base Material and Copper Foil<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Base Material<\/strong>: Select high - Tg FR - 4 copper - clad laminates (Tg\u2265170\u2103) with a CTE\u226418ppm\/\u2103, which meet the IPC - 4101 standard. The board thickness is designed to be 2.0 - 3.0mm according to current requirements. For a 3.0mm - thick board, pre - bake it at 120\u2103 for 2h to reduce the moisture absorption rate and avoid lamination bubbles.<\/li><li><strong>Copper Foil<\/strong>: Use 5OZ high - purity electrolytic copper foil (purity\u226599.9%) for all layers, with a tensile strength of \u2265300MPa and an elongation of \u22658%. Control the surface roughness of the copper foil at Ra 0.8 - 1.2\u03bcm to ensure both the bonding force with the resin and reduce the difficulty of etching.<\/li><\/ul><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(2) Adhesive and Auxiliary Materials<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Prepreg (PP)<\/strong>: Select 2116 fabric - based PP with a high resin content (55% - 65%) and a fluidity controlled at 25 - 35%. For areas where the inner - layer circuit gap is \u22650.3mm, switch to non - flow PP (fluidity &lt; 10%) to prevent excessive resin loss.<\/li><li><strong>Etch - resistant and Solder - mask Materials<\/strong>: Use a 50\u03bcm - thick high - temperature - resistant dry - film (conventional is 35\u03bcm) with an adhesion of 5B level to avoid pattern collapse during etching. Select epoxy - resin - type solder - mask ink with a Tg\u2265150\u2103 and an insulation resistance of \u226510\u00b9\u00b2\u03a9 to meet the insulation requirements for large currents.<\/li><\/ul><h3 class=\"header-vfC6AV auto-hide-last-sibling-br\">II. Core Process Flow: Fine - tuned Control for the Synergy of Thick Copper and Multi - layers<\/h3><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\">The process focuses on \"inner - layer formation \u2192 lamination integration \u2192 outer - layer processing \u2192 finished - product inspection\", and optimizes key parameters according to the characteristics of thick copper and multi - layers:<\/div><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(1) Inner - layer Fabrication: Precise Formation of Thick - copper Circuits<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Dry - film Lamination<\/strong>: In a Class 10000 clean room, laminate the dry - film by hot - pressing at 90\u2103 and a pressure of 0.8kg\/cm\u00b2, and use a vacuum laminator to remove bubbles (vacuum degree \u2264 10Pa).<\/li><li><strong>Exposure and Etching<\/strong>: Use LDI laser exposure (accuracy of \u00b110\u03bcm) and increase the exposure energy to 180 - 200mJ\/cm\u00b2. For etching, adopt a \"segmented process\". First, use a 15% ferric chloride solution to quickly etch 60% of the copper thickness, and then use a 10% solution for fine trimming, controlling the under - etching amount to \u226410\u03bcm.<\/li><li><strong>Inspection and Blackening<\/strong>: After etching, conduct a full inspection of circuit defects by AOI, with a qualification rate of \u226599.8%. \u968f\u540e\u8fdb\u884c\u9ed1\u5316\u5904\u7406\uff0c\u589e\u5f3a\u94dc\u7b94\u4e0e PP \u7684\u7ed3\u5408\u529b\u3002<\/li><\/ul><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(2) Lamination Process: Integrated Formation of the Multi - layer Structure<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Stacking and Positioning<\/strong>: Stack alternately according to the \"signal layer - ground layer - power layer\" (e.g., Top: signal \u2192 2: ground \u2192 3: power \u2192 4: power \u2192 5: ground \u2192 Bottom: signal). Use \"copper - foil positioning holes + laser alignment\" to keep the inter - layer misalignment \u2264 \u00b10.03mm.<\/li><li><strong>Step - by - step Pressing<\/strong>:<ul class=\"auto-hide-last-sibling-br\"><li><strong>Low - pressure Penetration (10kg\/cm\u00b2, 120\u2103)<\/strong>: Exhaust air and allow the resin to flow initially.<\/li><li><strong>Medium - pressure Diffusion (25kg\/cm\u00b2, 160\u2103)<\/strong>: Fill the circuit gaps and continue for 40 minutes.<\/li><li><strong>High - pressure Curing (35kg\/cm\u00b2, 180\u2103)<\/strong>: Ensure the inter - layer bonding force is \u22651.2N\/mm.<\/li><\/ul><\/li><li><strong>Cooling Control<\/strong>: Cool from 180\u2103 to 120\u2103 at a rate of 5\u2103\/min, and then cool naturally to reduce warping caused by thermal stress.<\/li><\/ul><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(3) Outer - layer Processing: Thick - copper Interconnection and Protection<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Drilling and Hole Treatment<\/strong>: Drill 0.3 - 1.0mm vias with a tungsten - steel drill bit (rotation speed of 25000rpm). After drilling, activate the hole wall through plasma cleaning (600W, 8min).<\/li><li><strong>Via Metallization<\/strong>: Use a vertical pulse electro - plating system with a plating solution containing polyether - type additives to achieve a copper thickness of over 30\u03bcm on the hole wall and improve uniformity by 20%.<\/li><li><strong>Surface Treatment<\/strong>: Plate nickel - gold (8\u03bcm nickel, 2\u03bcm gold) in the soldering area and tin - plate in the non - soldering area. Verify the adhesion by a cross - cut test with an adhesion of \u22654B level.<\/li><\/ul><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(4) Finished - product Inspection: Verification of Reliability and Performance<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Electrical Performance Testing<\/strong>: Use ICT to check for open - circuits and short - circuits. The via impedance tested by a flying - probe tester should be \u22645m\u03a9, and withstand a voltage test of 3000V AC\/1min without breakdown.<\/li><li><strong>Environmental Reliability<\/strong>: No delamination after 3 times of 288\u2103 tin - immersion, pass 100 cycles of - 40\u2103 ~ 125\u2103 thermal shock, and the temperature rise should be &lt; 30K when 100A current is applied for 1 hour.<\/li><\/ul><h3 class=\"header-vfC6AV auto-hide-last-sibling-br\">III. Key Technical Difficulties and Breakthrough Solutions<\/h3><div class=\"auto-hide-last-sibling-br paragraph-JOTKXA paragraph-element br-paragraph-space\">For the core pain points in production, improve the yield through process innovation:<\/div><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(1) Uneven Thick - copper Etching: Co - optimization of Materials and Equipment<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Difficulty<\/strong>: During the etching of 175\u03bcm thick copper, the etchant penetrates unevenly, and serrated edges are likely to occur.<\/li><li><strong>Solution<\/strong>: Use 355nm UV laser etching, and with an AI - based concentration monitoring system, adjust the etchant parameters in real - time to control the line - width accuracy within \u00b110\u03bcm.<\/li><\/ul><h4 class=\"header-vfC6AV auto-hide-last-sibling-br\">(2) Inadequate Lamination Resin Filling: Precise Matching of Resin and Pressure<\/h4><ul class=\"auto-hide-last-sibling-br\"><li><strong>Difficulty<\/strong>: The large gaps between thick - copper circuits may cause insufficient resin flow and form voids.<\/li><li><strong>Solution<\/strong>: Switch to 1080 high - resin - content PP, apply an impact pressure of 200PSI at 140\u2103, and use - 80kPa vacuum - assisted lamination.
