On the surface, lamination seems like a straightforward, almost brute-force process. You take layers of a circuit board, stack them together, and apply heat and pressure. It sounds simple, but in the world of high-tech electronics, the lamination process is anything but. It is the single most critical step in building a multi-layer PCB, transforming fragile individual circuit layers into a single, cohesive, and incredibly robust unit. If the PCB is a building, lamination is the foundation and the mortar, and its precision directly determines the products reliability, thermal performance, and electrical integrity.This is a deep dive into the "behind-the-scenes" process that gives your circuit boards their strength and stability, turning them into what we in the industry affectionately call "layer cakes."Visualizing the Process: From Stack-Up to "Layer Cake"Before the lamination press even comes into play, a meticulous "stack-up" is designed. This is the blueprint for the entire board, s...
