A new PCB material named 92ML has been introduced. This material is enhanced thermally and has been specifically manufactured and engineered for meeting the high power PCB application demands. Some of the advantages of the 92ML materials are the laminate systems are thermally conductive and based on epoxy, the 92Ml material is flame retardant as well as halogen free. A low cost system that is lead free solder compatible is also provided by the companies. The system is also capable of enhancing heat transfer capacity. The materials that are incorporated with the above mentioned characteristic are ideal for applications that have multilayer and that require thermal management of the entire board.
Up to 4oz copper cladding is being provided with the laminate material named 92ML. This thickness level is enough for meeting the requirements of the power distribution. The material also has high thermal conductivity that is up to 3.5 W/mK. This system is also familiar with the epoxy based system which is the most important specification that makes this system ideal for the PCB used in the applications such as the power supplies, automotive electronics, motor controllers as well as convertors. The materials also have a very high Tg value of about 160 degree Celsius and is also combined with coefficient of low Z axis of the thermal expansion in between 175 ppm per degree Celsius and 22 ppm per degree Celsius. This low coefficient of Z axis of the 92ML material can survive the soldier exposure that is free of lead and also ensures reliability testing of the high TG PCB boards. The 92ML laminates also have rheological characteristics that enable a very high degree of flow of resin. This element is very critical element of the high power printed circuit boards manufacturing that is multilayer in nature.
This 92ML laminates are also available in combination with the plates of aluminium that forms an insulated metal substrate. This configuration of this material is such that it has an integrated heat sink that can be worked as a machine that can serve as a chassis that is mechanical in nature. It is also characterised to have a very high level of adhesion that is thermally stable in nature to the substrate of aluminium pcb. This material of laminate can withstand solder exposure of about 288 degree Celsius for over than seven minutes. This time limit is sufficient for assembling of the final product without any issues. This material is also very useful in areas that have a very high operating temperature as well as very high power. The areas of applications include automotive lighting, LED modules and power devices.
