Requirements Analysis and Planning<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Defining Parameters: <\/strong>Determine projector power (e.g., 300W LED light source), size (e.g., compact size \u2264 200mm\u00b2), heat dissipation requirements (temperature rise \u2264 85\u00b0C), and EMC standards (e.g., CISPR 32).<\/li>\n\n\n\n<li><strong>Material Selection: <\/strong>Select the copper substrate type (single-sided\/double-sided\/multi-layer) and thickness (1.0-3.0mm). Use high-thermal-conductivity PP material (0.1-0.3mm thickness) for the insulation layer.<\/li>\n<\/ul>\n\n\n\n<p><strong>2. Schematic Diagram and Layout Design<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Modular Layout:<\/strong> Divide modules by function (e.g., light source driver, signal processing). Heat-generating components (LEDs, laser diodes) are concentrated at the board edges, utilizing the copper substrate edges for heat dissipation.<\/li>\n\n\n\n<li><strong>Core Component Positioning:<\/strong> Prioritize placement of the DMD chip and laser light source, ensuring precise alignment with the optical components (error \u2264 0.1mm).<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Thermal Design and Simulation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Copper Thickness Step Design:<\/strong> Use a 3-4oz copper layer in the core heat-generating area, tapering to 2oz at the periphery. A teardrop-shaped transition (angle \u2264 45\u00b0) is used to reduce thermal stress. <\/li>\n\n\n\n<li><strong>Via Array Optimization: <\/strong>Arrange 0.3mm diameter heat dissipation vias (density \u2265 4 vias\/cm\u00b2), combined with heat pipes (diameter 1.5mm) or phase change materials to enhance local heat dissipation.<\/li>\n\n\n\n<li><strong>Simulation Verification: <\/strong>Use ANSYS Icepak to simulate heat distribution, ensuring hotspot temperature rise \u2264 15\u00b0C, and adjust via placement and copper thickness.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Signal and Power Design<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High-Speed Signal Routing: <\/strong>HDMI\/VGA signal lines should be short and straight, avoiding 90-degree corners. Use serpentine routing to compensate for delays (differential line length error \u2264 5 mil).<\/li>\n\n\n\n<li><strong>Power Distribution: <\/strong>Separate power and ground planes, with ground trace widths \u2265 power lines (e.g., 10A power trace width \u2265 2mm). Critical signals (such as clocks) should be ground-wrapped, and return vias should be added when switching differential signal layers.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. Manufacturing and Assembly Considerations<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Drilling Specifications: <\/strong>Hole diameters should meet the board thickness ratio (\u2264 10:1) to avoid drill contamination, and depth-to-aperture ratios \u2264 0.8:1. <\/li>\n\n\n\n<li><strong>Surface Treatment: <\/strong>Use immersion gold (Immersion Gold) (Ni thickness 3-5\u03bcm, Au 0.05-0.1\u03bcm) to prevent deformation of the copper substrate caused by tin spraying.<\/li>\n\n\n\n<li><strong>Machining:<\/strong> Milling is used for copper substrate cutting, with edge chamfers of 0.8-1mm and a \u22652mm keep-out zone around the screw holes.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Verification and Testing<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>DRC Check:<\/strong> Ensure there are no shorts or opens, and that line widths and spacing meet manufacturing capabilities (e.g., minimum line width 0.1mm).<\/li>\n\n\n\n<li><strong>Prototype Testing: <\/strong>Test thermal performance (temperature rise \u2264 85\u00b0C), signal integrity (eye diagram test), and mechanical strength (vibration test).<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/08\/1-6.png\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/08\/1-6.png\" alt=\"How to Design a Projector Copper Based PCB?\" class=\"wp-image-11662\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Make_a_Projector_Copper_Based_PCB\"><\/span>How to Make a Projector Copper Based PCB?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>1.

Inner Layer Circuit Fabrication<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pretreatment: <\/strong>Chemical cleaning of the copper surface is performed to increase roughness and improve dry film adhesion.<\/li>\n\n\n\n<li><strong>Dry Film Lamination: <\/strong>A photosensitive dry film (15-25\u03bcm thick) is applied by hot pressing to cover the copper surface.<\/li>\n\n\n\n<li><strong>Exposure and Development: <\/strong>UV exposure is used to transfer the circuit pattern, and a developer (1% Na\u2082CO\u2083) is used to remove the uncured dry film.<\/li>\n\n\n\n<li><strong>Etching: <\/strong>An acidic copper chloride solution is used to etch the exposed copper areas, forming the inner layer circuits. The line width tolerance is \u2264\u00b110%. <\/li>\n\n\n\n<li><strong>Film Stripping and Inspection: <\/strong>A strong alkaline solution is used to remove the protective dry film, and AOI is used to inspect for circuit defects (shorts, opens).<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Lamination and Heat Dissipation Enhancement<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Brown Treatment: <\/strong>Chemically roughens the copper surface of the inner layer to enhance interlayer bonding.<\/li>\n\n\n\n<li><strong>Lamination and Lamination: <\/strong>The layers are stacked in the order of &#8220;copper foil &#8211; prepreg (PP) &#8211; inner layer &#8211; PP &#8211; copper foil&#8221; and pressed using a vacuum laminator (temperature 180-200\u00b0C, pressure 30-50 kg\/cm\u00b2).<\/li>\n\n\n\n<li><strong>Heat Dissipation Vias:<\/strong> Laser drilled (hole diameter 0.3mm, density \u2265 4 holes\/cm\u00b2), electroplated with copper (20-25\u03bcm) on the hole walls, and filled with thermally conductive silicone.<\/li>\n\n\n\n<li><strong>Copper Block Embedding: <\/strong>T-shaped copper blocks (2.5mm thick) are embedded in the high-heat zone, ensuring 100% contact with the light source module.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Outer Layer Circuitry and Plating<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Outer Layer Dry Film: <\/strong>Repeat the inner layer process, attach the dry film, and expose and develop, leaving the areas to be plated. <\/li>\n\n\n\n<li><strong>Electroplating Thickening: <\/strong>The copper layer is thickened to the designed thickness (e.g., 2oz in the HDMI signal area), and tin is simultaneously plated to protect the pads.<\/li>\n\n\n\n<li><strong>Etching and Tin Stripping:<\/strong> Etching removes unprotected copper, and then using a tin stripping solution to remove the tin layer, exposing the complete outer layer circuitry.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. Solder Mask and Surface Treatment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Solder Mask Printing: <\/strong>Screen-print solder mask ink (primarily green) to cover non-solderable areas.<\/li>\n\n\n\n<li><strong>Curing: <\/strong>UV exposure cures to retain the solder mask layer, followed by high-temperature baking (150\u00b0C) for hardening.<\/li>\n\n\n\n<li><strong>Surface Treatment:<\/strong> Immersion Gold (5\u03bcm Ni, 0.1\u03bcm Au), with key pads locally thickened to 0.2\u03bcm.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Forming and Inspection<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Outer Fabrication: <\/strong>PCB contours are cut using a CNC milling machine, and panels are separated using a V-cut assembly.<\/li>\n\n\n\n<li><strong>Electrical Testing: <\/strong>Flying probe testing is used to check connectivity and insulation resistance.<\/li>\n\n\n\n<li><strong>Final Inspection: <\/strong>Visual inspection or AOI inspection is performed to check appearance (e.g., ink misalignment, board warping), ensuring compliance with IPC-A-600 standards.<\/li>\n<\/ul>\n\n\n\n<p><strong>7.
