increase<\/a> in 2026 is real, but it is not one continuous rise across every board type. Resonac and Panasonic announced large CCL and prepreg revisions during the year, while an August PCB-pricing update showed that temporary surcharges for some standard FR4 volume orders could also be removed when conditions eased.<\/p>\n<p>For PCB buyers, the useful question is not \u201cHow much did all boards rise?\u201d It is \u201cWhich material, supplier notice, effective date, stackup, copper weight, and order size apply to this quotation?\u201d This timeline separates those factors and explains why raw-material percentages cannot be copied directly into a finished-board price.<\/p>\n<figure style=\"width: 100%; max-width: 600px; margin: 24px auto;\">\n    <img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/08\/pcb-raw-material-price-increase-hero.jpg\" alt=\"PCB Raw Material Price Increase with CCL, prepreg and copper foil\" style=\"display: block; width: 100%; max-width: 600px; max-height: 400px; height: auto; object-fit: contain; margin: 0 auto;\"><br \/>\n  <\/figure>\n<h2><span class=\"ez-toc-section\" id=\"What_Changed_in_the_PCB_Materials_Market_in_2026\"><\/span>What Changed in the PCB Materials Market in 2026?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>PCB material suppliers responded to higher copper foil, glass cloth, resin, solvent, energy, labor, and logistics costs with multiple product-specific price notices. The timing and scope differed by supplier: one notice covered all CCL and prepreg products, while others separated general glass-epoxy, low-loss, substrate, CEM-3, and flexible materials.<\/p>\n<p>That distinction matters because a PCB quotation does not buy \u201craw material\u201d as one commodity.

The May-effective notice applied a larger increase to general CCL than to general prepreg, while the August-effective notice reversed that relationship: general prepreg received the larger percentage adjustment.<\/p>\n<p>Low-loss materials, substrate materials, CEM-3, and FCCL also had separate rates.

For a <strong>prepreg price increase PCB<\/strong> cost review, the stackup and number of bonding interfaces matter more than the finished board outline alone.<\/p>\n<p>Prepreg cannot be replaced solely on price. The change can affect dielectric thickness, impedance, resin fill around copper, lamination flow, thermal performance, and qualification status.

The verified Resonac notice identified tight copper-foil supply and higher prices as part of its CCL\/prepreg revision background. It did not state one universal copper-foil percentage that could be applied to all boards.<\/p>\n<p>A copper foil price increase usually matters more to heavy-copper boards, large panels, high-layer-count designs, and constructions with high copper utilization. Surface treatment, etching difficulty, plating requirements, and yield still affect the final quotation independently of commodity or foil input prices.<\/p>\n<figure style=\"width: 100%; max-width: 600px; margin: 24px auto;\">\n    <img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/08\/ccl-prepreg-copper-foil-materials.jpg\" alt=\"CCL panels, prepreg sheets and copper foil used in PCB production\" loading=\"lazy\" style=\"display: block; width: 100%; max-width: 600px; max-height: 400px; height: auto; object-fit: contain; margin: 0 auto;\"><br \/>\n  <\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Why_Did_Standard_FR4_Pricing_Ease_While_Special_Materials_Stayed_Exposed\"><\/span>Why Did Standard FR4 Pricing Ease While Special Materials Stayed Exposed?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Standard FR4 pricing eased in one large-order channel because material and component conditions improved enough for temporary volume surcharges to be removed.

The rates apply to specified suppliers, products, dates, and base prices.<\/p>\n<h3>Can the supplier percentages be added together?<\/h3>\n<p>No. They are separate notices for different suppliers and effective dates. Even two notices from the same supplier may apply to different current price bases, so adding the percentages would misrepresent the published information.<\/p>\n<h3>Does a 30% CCL increase make the finished PCB 30% more expensive?<\/h3>\n<p>Not necessarily. CCL is one part of finished-board cost. The actual effect depends on laminate usage, panel efficiency, layers, copper, drilling, imaging, plating, testing, yield, quantity, and inventory.<\/p>\n<h3>Why can standard FR4 pricing fall while low-loss materials remain high?<\/h3>\n<p>Standard FR4 usually has broader supply and greater substitution flexibility. Low-loss and specialty systems may have fewer qualified sources, tighter specifications, and longer validation cycles.<\/p>\n<h3>Which date matters: the notice date or the effective date?<\/h3>\n<p>The effective date normally determines which shipments or orders use the revised supplier price. Existing inventory, contracts, and regional terms can still affect when a PCB quotation changes.<\/p>\n<h3>Why does prepreg pricing matter for multilayer boards?<\/h3>\n<p>Prepreg bonds layers and controls dielectric thickness and resin fill. Multilayer boards use multiple prepreg interfaces, so material choice and layer count can increase exposure.<\/p>\n<h3>Are copper prices and copper foil prices the same?<\/h3>\n<p>No. Copper foil includes conversion, treatment, thickness, quality, supply, and contract factors beyond the underlying metal price. A commodity move cannot be copied directly into a foil or PCB percentage.<\/p>\n<h3>Should buyers change laminate brands to save cost?<\/h3>\n<p>Only after confirming electrical, thermal, mechanical, regulatory, and customer requirements. A cheaper laminate is not equivalent if it changes impedance, loss, reliability, processing, or qualification status.<\/p>\n<h3>How long should a PCB price quote remain valid?<\/h3>\n<p>There is no universal period during volatile conditions. Buyers should use the validity printed on the current quotation and re-confirm material availability before a delayed purchase order.<\/p>\n<h3>What files help a manufacturer assess material cost accurately?<\/h3>\n<p>Provide fabrication data, stackup, board dimensions, finished thickness, copper weights, material grade, quantity, panel constraints, test requirements, and delivery schedule.<\/p>\n<p><em>Market data note: this article uses issuer notices dated January 16, April 9, June 13, June 26, and August 3, 2026.
