It can be rigid or flexible; the selection must be depended on the nature of application, manufacturing process, and application area.<\/li>\n<li><strong>Cover Layer<\/strong> \u2013 This is the insulating material applied over conductive pattern. A good insulation protects the circuitry from environmental extremes, whilst providing comprehensive electrical insulation.<\/li>\n<li><strong>Reinforced Adhesive<\/strong> \u2013 The mechanical properties of adhesives can be improved by adding glass fibers. An adhesive with the addition of glass fibers is termed as reinforced adhesive.<\/li>\n<li><strong>Adhesiveless Materials<\/strong> \u2013 Generally, adhesiveless materials are constructed by flowing a hot polyimide (Commonly used polyimide is Kapton) between two layers of copper. The polyimide acts as a bonding agent, eliminating the need of using adhesives like epoxy or acrylic.<\/li>\n<li><strong>Liquid Photoimageable Solder Mask<\/strong> \u2013 Compared to dry film solder mask application, LPSM is an accurate and versatile method. The technique is chosen to apply a thin and even layer of solder mask. Here, solder mask is sprayed on the board using photographic imaging technique.<\/li>\n<li><strong>Curing<\/strong> \u2013 It is the process of applying heat and pressure on the laminate. This is done to produce a bond.<\/li>\n<li><strong>Clad or Cladding<\/strong> &#8211; A thin layer or sheet of copper foil bonded to a laminate. This assembly can be used a base material for PCBs.<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\">The aforementioned technical terms will be beneficial for you when stipulating requirements of <a href=\"http:\/\/www.rigiflex.com\/products-services\/rigid-pcb\/12-layer-rigid-polyimide-heatsink\">12 layer rigid PCBs<\/a>. However, these are not a complete list. PCB manufacturers use several other terms when communicating with customers. If you find difficulty in understanding any term during the conversation, don\u2019t hesitate to interrupt the manufacturer. Ask questions when in doubt. This helps you have a healthy and efficient communication, mutually beneficial for you and the manufacturer.<\/p>\n<p align=\"justify\"><a href=\" https:\/\/www.rigiflex.com\/pcb-quote\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-781 size-full\" src=\" https:\/\/www.rigiflex.com\/blog\/wp-content\/uploads\/2023\/04\/PCB-Online-Quote.png\" alt=\"PCB Online Quote\" width=\"247\" height=\"50\" \/> <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Several material options are available to customize 12 layer PCB boards.
