Immediately after coating, send it to a hot - air oven and execute staged curing: 80\u2103 (30min) for pre - curing \u2192 120\u2103 (40min) for semi - curing \u2192 180\u2103 (60min) for complete curing, ensuring the cross - linking degree of the dielectric layer is \u2265 90% and the breakdown voltage is \u2265 2.5kV\/mm.<\/li><li><strong>Dielectric Layer Quality Inspection<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>Use a \"pin - disk - type insulation tester\" to detect the insulation of the double - sided dielectric layer (insulation resistance \u2265 10\u00b9\u00b2\u03a9), sampling 20 points per square meter. Scan the whole board with a laser thickness gauge and record the thickness difference between the two sides (required to be \u2264 5\u03bcm). For local bubbles or pinholes (diameter \u2265 50\u03bcm), use the \"resin re - coating + local curing\" method for repair. After repair, re - test the insulation.<\/li><\/ol><h3 class=\"header-vfC6AV auto-hide-last-sibling-br\">III. Double - sided Copper Foil Lamination and Circuit Manufacturing: Building Two - way Conductive Layers (Procedures 5 - 7)<\/h3><ol class=\"auto-hide-last-sibling-br\" start=\"5\"><li><strong>Double - sided Copper Foil Hot - pressing Lamination<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>Select 1OZ (35\u03bcm) electrolytic copper foil and laminate it simultaneously on both sides of the dielectric layer through a double - station hot - press: at a temperature of 160\u2103, a pressure of 20kg\/cm\u00b2, and a holding time of 30min. Before hot - pressing, apply a small amount of coupling agent (silane - based) between the copper foil and the dielectric layer to enhance the bonding force (required peel strength \u2265 1.5kg\/cm). After lamination, sample and test with a tensile testing machine, and the non - qualification rate should be \u2264 0.5%.<\/li><li><strong>Double - sided Synchronous Pattern Transfer<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>Adopt the \"double - sided alignment exposure\" process: simultaneously coat photosensitive film (thickness of 15\u03bcm) on the double - sided copper foil. Ensure the alignment of double - sided patterns through an optical alignment system (positioning accuracy of \u00b12\u03bcm). Expose simultaneously with a UV exposure machine (energy of 100mJ\/cm\u00b2), develop by soaking in a developing solution (1.0% sodium carbonate solution) to expose the copper foil to be etched. After development, check for double - sided pattern misalignment (required to be \u2264 3\u03bcm) through CCD visual inspection.<\/li><li><strong>Double - sided Etching and Film Stripping<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>Put the substrate into a double - sided spray etching machine. Use an acidic copper chloride etchant (concentration of 180g\/L, temperature of 45\u2103). Control the double - sided etching rate at 1.2\u03bcm\/min. Ensure the double - sided line - width deviation is \u2264 \u00b13\u03bcm through \"etching time - difference compensation\" (adjust \u00b15 seconds according to the thickness deviation of the double - sided copper foil). After etching, strip the film simultaneously with a 5% sodium hydroxide solution. After film stripping, conduct AOI inspection, focusing on checking for open - circuits, short - circuits, and edge burrs (\u2264 5\u03bcm).<\/li><\/ol><h3 class=\"header-vfC6AV auto-hide-last-sibling-br\">IV.

The hole - position deviation is \u00b10.02mm. After drilling, blow out the metal debris in the holes with compressed air (0.5MPa) to avoid short - circuits. For small holes with an aperture \u2264 0.3mm, adopt the \"laser pre - drilling + mechanical fine - drilling\" composite process to reduce the risk of drill breakage.<\/li><li><strong>Via Metallization and Surface Treatment<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>First, conduct electroless copper plating (copper - plating thickness of 0.8 - 1\u03bcm) to ensure the conductivity of the hole wall. Then, thicken the copper layer on the hole wall to 25\u03bcm through vertical electro - plating, and at the same time, electro - plate and thicken the double - sided circuit surface by 5\u03bcm. For surface treatment, use \"double - sided synchronous gold - plating\" (2\u03bcm gold layer, 5\u03bcm nickel layer) or \"tin - spraying\". After treatment, verify the weather resistance through a salt - spray test (no corrosion in 48 hours). For substrates used in new - energy vehicles, additionally conduct \"edge sealing\" (coat silicone rubber) to enhance moisture resistance.<\/li><li><strong>Shape Processing and Finished - product Inspection<\/strong><div class=\"container-utlnW2 md-box-line-break wrapper-d0Cc1k undefined\">\u00a0<\/div>Cut the shape of the substrate with a CNC milling machine at a cutting speed of 50mm\/min to avoid burrs on the metal base.

Finally, sample for a \"temperature - cycling test\" (-40\u2103~125\u2103, 500 times), and it is qualified if there is no delamination or hole - copper fracture.<\/li><\/ol>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8e0b32f elementor-widget elementor-widget-wd_image_or_svg\" data-id=\"8e0b32f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_image_or_svg.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\n\t\t<div class=\"wd-image text-left\">\n\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1066\" height=\"800\" src=\"https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB.webp\" class=\"attachment-full size-full\" alt=\"There are traditional metal substrates (single - layer\/double - layer, with an insulated layer covered by copper, suitable for LED lighting), metal - core PCBs (where the metal core is embedded inside multi - layer boards, used in power modules of new - energy vehicles), and IMS (Insulated Metal Substrates) (thin dielectric layer + thick copper, for high - frequency scenarios like 5G base - station power amplifiers).\" srcset=\"https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB.webp 1066w, https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB-300x225.webp 300w, https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB-1024x768.webp 1024w, https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB-768x576.webp 768w, https:\/\/ulpcb.com\/wp-content\/uploads\/2025\/09\/MCPCB-16x12.webp 16w\" sizes=\"(max-width: 1066px) 100vw, 1066px\" \/>\t\t\t\t\t<\/div>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Home\u9875\u9762 Metal PCB Select 6061 aluminum alloy (conventional thickness of 1.0 &#8211; 3.0mm) or oxygen &#8211; free copper (for high<\/p>","protected":false},"author":1,"featured_media":0,"parent":15,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-47","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/pages\/47","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/comments?post=47"}],"version-history":[{"count":10,"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/pages\/47\/revisions"}],"predecessor-version":[{"id":1254,"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/pages\/47\/revisions\/1254"}],"up":[{"embeddable":true,"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/pages\/15"}],"wp:attachment":[{"href":"https:\/\/ulpcb.com\/pl\/wp-json\/wp\/v2\/media?parent=47"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
