Isola 185HR belongs on a manufacturing page about reliability, not on an RF-material page. It is specified when a multilayer PCB must survive lead-free assembly, repeated thermal exposure, demanding plated holes, humid-bias service or a long product life. The useful...
ITEQ IT-150GS is best treated as a reliability-first, halogen-free, mid-loss FR-4 material. It is not the answer to an extreme long-channel loss problem. It is the answer when a multilayer board needs better electrical behavior than standard-loss FR-4 while also...
ITEQ IT-968G is most useful when the engineering team needs more channel margin than mainstream high-speed FR-4 can provide but does not automatically need the cost, supply-chain commitment, or processing discipline of the lowest-loss tier. Its value is not that it is...
ITEQ IT-988GSE should be chosen from a quantified channel budget, not from the aggregate label on a switch, router, storage system, or backplane. “400G” does not reveal the lane rate, modulation, symbol rate, routing length, connector count, package loss, via...
“NPG-170D” is a family-level shorthand, not a complete production specification. Nan Ya’s current public datasheet identifies at least NPG-170DR and NPG-170DTL as separate glass-cloth epoxy, flame-retardant materials. Both are described as halogen-, antimony-, and...
Panasonic MEGTRON 7N is best understood as a platform material for difficult high-speed multilayers, not as a universal “server laminate.” The public Panasonic product is laminate R-5785(N) with prepreg R-5680(N). Panasonic positions the MEGTRON 7 family for...
Ventec VT-481 is a mid-Tg, phenolic-cured FR-4.0 laminate and prepreg system intended for lead-free assembly, low z-axis thermal expansion, CAF resistance, and stable mainstream multilayer production. It should be selected when the dominant risk is interconnect and...
TUC TU-872 SLK occupies a commercially useful middle ground. It is a high-performance modified-epoxy FR-4 system designed for lower Dk/Df than ordinary high-Tg FR-4 while retaining modified-FR-4 process compatibility, strong thermal reliability, moisture resistance,...
Shengyi S1000-2M is a high-Tg, low-CTE FR-4.0 laminate for high-layer-count boards that must survive lead-free processing and maintain plated-through-hole and insulation reliability. Shengyi highlights 180°C Tg by DSC, 185°C by DMA, 355°C Td, 41 ppm/°C z-axis CTE...
Isola P25N is a polyimide UL HB No-Flo® specialty prepreg. It is not a copper-clad laminate and should not be specified as though it replaces a core material. Its job is to create a controlled bond line in structures where normal prepreg flow would contaminate a...
