Design Optimization and Layout Planning<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use EDA software (such as Altium, Cadence) for circuit design, focusing on optimizing high-density routing. Verify signal integrity through 3D modeling to ensure line width\/spacing is controlled within 3-4mil, hole diameter 3-5mil, and meet impedance matching requirements. <\/li>\n\n\n\n<li>Adopt blind\/buried via design to replace traditional through-holes, reducing interlayer signal paths and enhancing space utilization.<\/li>\n<\/ul>\n\n\n\n<p><strong>2. Material Selection and Pretreatment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Select low dielectric constant (Dk) and high-frequency performance materials (such as LCP liquid crystal polymer) to reduce signal loss. The substrate uses thin copper foil (typically 0.5-2oz) combined with prepreg for interlayer bonding. <\/li>\n\n\n\n<li>The pretreatment stage requires chemical copper deposition to ensure uniform copper layer adhesion and enhance conductivity.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Inner Core Board Fabrication<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The inner core board forms circuit patterns through photolithography-etching processes. Steps include: cleaning the copper-clad laminate \u2192 coating photosensitive dry film \u2192 UV exposure to transfer design patterns \u2192 developing to remove uncured dry film \u2192 alkaline etching to remove exposed copper \u2192 stripping and cleaning. <\/li>\n\n\n\n<li>Use AOI (Automated Optical Inspection) to verify inner layer circuit accuracy, ensuring no short\/open circuit defects.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Microvia Drilling and Plating<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Employ laser drilling technology (CO\u2082 laser\/UV laser) to fabricate micro blind\/buried vias with hole diameters controlled within 50-150\u03bcm. Optimize laser parameters to minimize the heat-affected zone (HAZ) and avoid carbonization. <\/li>\n\n\n\n<li>After drilling, perform plasma cleaning to remove residues, followed by chemical copper deposition + electroplating to form a 25\u03bcm thick copper layer, ensuring uniform via wall conductivity.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. Lamination and Stack-up Structure Construction<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Achieve multi-layer structures through sequential lamination processes. Steps include: core board positioning \u2192 stacking (core + prepreg + copper foil) \u2192 vacuum hot press curing under high temperature and pressure. Control lamination temperature (170-200\u00b0C) and pressure (300-500psi) to ensure no interlayer bubbles\/cracks. <\/li>\n\n\n\n<li>Adopt symmetric stack-up design to reduce board warpage and improve mechanical stability.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Outer Layer Circuit Formation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The outer copper foil forms circuit patterns through photolithography-etching processes, similar to inner layers but using positive film processes. <\/li>\n\n\n\n<li>Steps include: coating photosensitive film \u2192 exposure and development \u2192 electroplating to thicken copper layer (to 25\u03bcm) \u2192 etching to remove excess copper \u2192 stripping tin to protect circuits. Use flying probe testing to verify outer layer electrical connections, ensuring no open\/short circuits.<\/li>\n<\/ul>\n\n\n\n<p><strong>7. Surface Treatment and Impedance Control<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Select surface treatment processes (such as ENIG, OSP, gold plating) based on application requirements to enhance soldering reliability. Perform impedance testing in critical areas to ensure signal integrity. <\/li>\n\n\n\n<li>Adopt differential pair routing + ground plane optimization to control crosstalk and electromagnetic interference (EMI).<\/li>\n<\/ul>\n\n\n\n<p><strong>8. Reliability Testing and Quality Verification<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Conduct thermal cycling tests (-55\u00b0C to 150\u00b0C), vibration tests, and X-ray inspections to verify microvia integrity. Analyze via wall filling quality through metallographic sectioning to avoid voids\/delamination defects. <\/li>\n\n\n\n<li>Perform electrical performance tests (such as flying probe testing) to ensure products meet design specifications.<\/li>\n<\/ul>\n\n\n\n<p><strong>9. Prototype Cutting and Packaging<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use CNC or laser cutting to segment large panels into individual PCB prototypes, with edge chamfering to prevent damage. <\/li>\n\n\n\n<li>Clean to remove residual chemicals, and vacuum package to prevent moisture\/dust. Attach quality inspection reports containing test data and process parameters for customer verification.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Much_Does_HDI_PCB_Prototyping_Cost\"><\/span>How Much Does HDI PCB Prototyping Cost?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The<strong> prototyping cost<\/strong> for HDI (High-Density Interconnect) PCBs typically spans<strong> $200 to $2,500+<\/strong>, contingent on complexity and specifications.
