Standard FR-4 Tg 135-150FR-4 Tg 135, FR-4 Tg 150, Shengyi S1000-2, Kingboard KB-6160, ITEQ IT-158, Nan Ya NP-155Mainstream rigid PCB builds with standard electrical and thermal requirements.Tg class, UL 94 V-0, CTI, CAF, copper weight, lead-free reflow exposure.Exact laminate brand is selected during stack-up and quotation review.
Lead-free FR-4 upgradeIsola IS410, Isola 370HR, Panasonic R-1755V, ITEQ IT-180AAssemblies with higher reflow stress or more demanding reliability expectations.Tg/Td, Z-axis expansion, T288/T300, via reliability, material certificate needs.This is a reference set, not a public stock promise.

These are common material classes and reference laminate models for RFQ discussion. Exact brand, grade, stack-up, certificate scope, and availability are confirmed per project.
