Advanced HDI processes can achieve 50-75 \u03bcm (2-3 mil) or even finer in specialized applications. The specific capabilities depend on the manufacturer's equipment and processes.<\/p>\r\n      <\/div>\r\n    <\/div>\r\n    <div class=\"faq-item\" itemscope=\"\" itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\r\n      <h3 class=\"faq-question\" itemprop=\"name\">How many layers can an HDI PCB have?<\/h3>\r\n      <div class=\"faq-answer\" itemscope=\"\" itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\r\n        <p itemprop=\"text\">HDI PCBs can have anywhere from 4 to 40+ layers, depending on the application requirements. Most commercial HDI designs range from 6 to 14 layers, while high-end telecommunications and computing applications may use 20+ layers.
