Abstract:
A multilayer printed circuit board (PCB) includes a laminate between a first core and a second core. The first core is located in a middle position of the multi-layer PCB and includes a resistive heating element directly upon a first core substrate. A portion of the resistive heating element protrudes from the multi-layer PCB perimeter. A laminator that fabricates the PCB includes a platen, a power supply, a processor, and memory that has program instructions embodied therewith which are readable by the processor to cause the laminator to position the platen against a surface of the multi-layer PCB and cure the laminate by heating the multi-layer PCB with the platen and cure the laminate by heating the multi-layer PCB with the resistive heating element.
