Mida peab teadma lainetakistust omavate plaatide projekteerimisel:<\/p>\n

    \n
  1. Erinevad materjalide paksused omavad erinevaid dielektrilisi konstante. Meil kasutuselolevate materjalide konstandid leiad\u00a0siit<\/a><\/strong>, siit<\/a><\/strong> ja siit<\/a><\/strong>;<\/li>\n
  2. Liidese t\u00f6\u00f6sagedust. Sellele vastavat dielektrilist konstanti vaata eelnevast materjalide tabelist;<\/li>\n
  3. Sisekihtide nominaalvasepaksused kahanevad meie protsessis 3\u00b5! N\u00e4iteks 18\u00b5 fooliumiga sisekihi vasepaksus j\u00e4\u00e4b peale tootmist 15\u00b5 st tehes lainetakistuse arvutusi tuleb sisestada programmi 15\u00b5. See suurus s\u00f5ltub tootja poolt kasutatavatest protsessidest ja v\u00f5ib olla erinev meie 3\u00b5-st.<\/li>\n
  4. V\u00e4liskihtide vasepaksused suurenevad galvaanilise vasetamise t\u00f5ttu v\u00e4hemalt 35\u00b5 v\u00f5rra st arvestada tuleb alusfoolium + galvaaniline vasetamine (12\u00b5 + 35\u00b5 =47\u00b5);<\/li>\n
  5. V\u00e4liskihtide topograafiat ehk vaseala \u00fchtlust. Mitte\u00fchtlane topograafia tekitab olukorra, kus h\u00f5redamas vasealas on vasepaksus radadel kuni 2x suurem v\u00f5rreldes t\u00e4idetud maa-alaga;<\/li>\n
  6. Radade kahanemist s\u00f6\u00f6vitusprotsessi k\u00e4igus. Raja laius kahaneb minimaalselt alusfooliumi paksuse v\u00f5rra;<\/li>\n
  7. Vajalike sise- ja vahekihtide olemasolu tr\u00fckkplaatide tarnijal. M\u00f5istlik on projekteerimise k\u00e4igus selgitada v\u00e4lja valitud tarnija laos olevad materjalid ja projekteerida vastavalt nendele. Meie materjalivaliku leiad siit<\/a><\/strong>. Kui teie etteantud \u00fclesehitus ja tarnija poolt pakutud \u00fclesehitus ei \u00fchti, siis arvutage lainetakistus uuesti kasutades tarnija \u00fclesehitust!<\/li>\n
  8. Lisage failidesse alati spetsifikatsioon, kus n\u00e4idake \u00e4ra lainetakistuse t\u00fc\u00fcp (single, diff pair), takistuse suurus oomides ja tolerants, signaali ja tugikihi numbrid (signal, ref) raja laius ja vahe (hea oleks ka D-kood). \u00dcks spetsifikatsiooni v\u00f5imalustest on toodud allpool:<\/li>\n<\/ol>\n
