Siab- txheej - suav PCB thev naus laus zis txuas ntxiv mus; cov lus qhia hauv qab no sawv cev rau qhov tseem ceeb ntawm kev txhim kho yav tom ntej. Nrog rau kev loj hlob ntawm Chiplet ntim, HDI boards yav tom ntej yuav siv 3D stacking architectures los ua kom luv luv ntawm kev sib txuas, thaum cov txheej txheem ntim khoom siab heev -xws li CoWoS-yuav ua rau cov khoom ntim ncaj qha mus rau PCB substrate.
Hauv cov chaw kuaj mob, optical PCBs twb tau pib hloov cov teeb liab hluav taws xob rau hauv cov pulses optical rau kev sib kis. Corning, piv txwv li, tau ua kom pom lub rooj tsav xwm sib txuas sib txuas uas sib txuas nrog cov kab hluav taws xob kho qhov muag nrog rau cov kab tooj liab ib txwm muaj; Qhov kev tsim kho tshiab no ua tiav cov ntaub ntawv xa tawm ntau dua 1 Tbps thaum tib lub sijhawm txo hwj chim siv los ntawm 90%.
Tsav los ntawm kev nce qib hauv 5G millimeter-wave thiab terahertz thev naus laus zis, cov ntaub ntawv PCB tau hloov mus rau ntau zaus thiab qis dua teeb liab; yog li ntawd, siab - cov ntaub ntawv zaus xws li PTFE thiab Liquid Crystal Polymer (LCP) tau pom ntau daim ntawv thov. Hauv siab -kawg daim ntawv thov-xws li AI servers-PCB substrates tam sim no feem ntau siv siab- zaus, siab-ceev tooj liab-Clad Laminates (CCL) ntawm chav kawm M6 los yog siab dua (xws li Panasonic's Megtron 6); ntau tus qauv tsim txawm tias pib koom nrog cov khoom siv tshiab dua - tiam Megtron 8 (M8).
Embedding passive Cheebtsam-xws li resistors thiab capacitors- lossis txawm tias cov khoom siv nyob rau hauv cov txheej txheem dielectric tuaj yeem txo qhov kev cia siab rau saum npoo- cov khoom siv txuas ntxiv thiab txhim kho kev sib xyaw ua ke kom ceev. Piv txwv li, Bomin Electronics 'ultra- siab- txheej PTFE board technology, featuring embedded resistors, tau ntse enabled multi-channel teeb liab synchronization nyob rau hauv radar modules, ua rau ib tug 50% txo nyob rau hauv tus nqi me ntsis yuam kev.
Bomin Electronics tuav daim ntawv pov thawj rau "Txoj Kev rau Fabricating Ultra-High- Txheej PCBs Siv Sintered Copper Paste." Los ntawm kev sib xyaw ua ke ntawm modular sub-board tsim thiab tooj liab muab tshuaj ua ntej- cov txheej txheem kho, txoj kev no ua tiav cov txheej txheem sib xyaw ua ke hauv 2 mils (kwv yees li 50 μm), yog li kov yeej cov kev txwv lub cev muaj nyob hauv cov txheej txheem tsim khoom ib txwm muaj. Cov thev naus laus zis no txhawb nqa cov khoom loj ntawm PCBs nrog ntau tshaj 52 txheej, txhawb kev tsim cov khoom lag luam los ntawm 70-80% feem ntau ntawm cov tsoos multilayer boards mus rau ntau dua 90%.
