The fabricated board then carries a discontinuity at the very region that should preserve the RF structure, board-level correlation misses the intended posture, and later RF measurements have to diagnose a mismatch or excess loss that began in manufacturing execution, not in the material name. The team is no longer comparing laminate options. It is reopening hybrid-stackup and transition-control decisions after release looked complete.\u003C/p>\n\u003Cp>The harder version appears in hybrid stackups that combine PTFE-based RF material with ordinary FR-4 to balance cost and path sensitivity. On paper, the material split looks efficient. In the drill shop, it becomes a surface-chemistry problem. PTFE is chemically inert and extremely smooth. If the shop does not run strict \u003Ccode>PTFE Plasma Desmear\u003C/code> or plasma etchback before plating, the hole wall will not hold copper reliably. A factory without the correct plasma capability may still force the build through plating, but the result is microscopic \u003Ccode>Plating Voids\u003C/code> in the via barrel. After reflow shock, those vias can crack outright or, above \u003Ccode>10 GHz\u003C/code>, start behaving like an \u003Ccode>Intermittent Attenuator\u003C/code> that changes loss unpredictably as the defect opens under stress. The same board can be damaged again if the shop quietly substitutes rough standard ED copper where low-profile foil was intended. Under \u003Ccode>Skin Effect\u003C/code>, the rough copper teeth act like a lossy saw blade against the microwave current, driving insertion loss far above expectation. That is why RF manufacturing is not solved by buying expensive Rogers-class material.
