multilayer PCB contains prepreg, even though it is rarely visible after the board is manufactured.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During lamination, prepreg bonds multiple copper-clad cores into a single rigid structure while providing electrical insulation between conductive layers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its resin content, thickness, and flow characteristics all influence PCB quality, dimensional stability, impedance control, and long-term reliability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding prepreg helps engineers develop more reliable stackups and communicate more effectively with PCB manufacturers.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\"

Is PCB Prepreg?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Prepreg is short for <strong>pre-impregnated material<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It consists of woven fiberglass cloth that has been impregnated with epoxy resin that is only partially cured.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the resin has not fully hardened, prepreg remains flexible before lamination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When heat and pressure are applied during PCB manufacturing, the resin softens, flows into microscopic gaps, and finally cures into a rigid insulating layer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u0642\u0631\u0627\u0621\u0629 \u0630\u0627\u062a \u0635\u0644\u0629:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a

class=\"wp-block-heading\">What Is Prepreg Made Of?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Although prepreg looks like a simple sheet of fiberglass, it is carefully engineered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It generally contains:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Woven fiberglass cloth<\/li>\n\n\n\n<li>Partially cured epoxy resin<\/li>\n\n\n\n<li>Controlled resin content<\/li>\n\n\n\n<li>Flame-retardant additives (for FR4 systems)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Different combinations are used depending on the required board thickness and electrical performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does Prepreg Do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Prepreg performs several functions during multilayer PCB manufacturing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bonding Layers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Its primary job is bonding adjacent PCB cores together during lamination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without prepreg, individual layers would not become a single circuit board.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u0627\u0644\u0639\u0632\u0644 \u0627\u0644\u0643\u0647\u0631\u0628\u0627\u0626\u064a<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After curing, prepreg becomes the dielectric material separating conductive copper layers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its dielectric properties influence impedance and signal integrity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Filling Gaps<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">During lamination, resin flows around etched copper patterns and fills small voids.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Proper resin flow helps improve layer adhesion and reduce manufacturing defects.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Controlling Board Thickness<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The number and thickness of prepreg sheets contribute to the finished PCB thickness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Manufacturers choose different prepreg combinations to meet customer specifications.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\"

class=\"wp-block-paragraph\">Generally:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Higher resin content improves filling around heavy copper.<\/li>\n\n\n\n<li>Lower resin content helps maintain tighter dielectric spacing.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Selecting the correct resin content depends on the PCB stackup and manufacturing process.<\/p>\n\n\n\n<h2
