Sequential Lamination PCB: Complete Guide to Multi-Stage Pressing Technology
Sequential lamination is a multilayer PCB fabrication process where individual core layers or groups of layers are laminated in separate stages, enabling complex stackups with buried vias, mixed construction, and ultra-high layer counts that cannot be achieved in a single lamination cycle. This process is essential for aerospace, military, and advanced telecommunications applications requiring 20+ […]
PCB Back Drilling: The Complete Guide to Via Stub Elimination
PCB Back Drilling: The Complete Guide to Via Stub Elimination PCB back drilling is a controlled depth drilling technique that removes the non-functional portion of plated through-hole vias, eliminating via stubs that cause signal integrity problems at high frequencies. This technique is essential for DDR5 memory interfaces, PCIe Gen 4/5, and other high-speed digital designs […]
