Kukhala ndi chidziwitso choyambirira cha mawu osindikizidwa a board board kungapangitse kugwira ntchito ndi kampani yopanga PCB mwachangu komanso kosavuta.Kalozerayu wa mawu a board board adzakuthandizani kumvetsetsa mawu ena omwe amapezeka kwambiri pamakampani.Ngakhale iyi si mndandanda wazinthu zonse, ndi chida chabwino kwambiri chothandizira kutanthauzira kwanu.
Kukhala patsamba lomwelo ndi wopanga makontrakitala anu (CM) ndikofunikira kuti chifaniziro cholondola cha cholinga chanu chipangidwe popanda kuvutika chifukwa chosafunikira.kuchedwa kwa mawu, kukonzanso ndi/kapena ma boardboard.Kuyankhulana mwachilungamo pakati pa onse omwe akukhudzidwa ndi chitukuko cha komiti yanu ndiye chinsinsi.
Mndandanda Wamatchulidwe Ofunikira a PCB Design
Terminology Yosindikizidwa ya Circuit Board
Mawu ena ofunikira osindikizidwa a board amayang'ana kufotokozera mawonekedwe a PCB.Mawuwa amatchulidwanso pakupanga ndi kupanga, kotero ndikofunikira kuti muphunzire izi poyamba.
Masanjidwe:Mabodi onse ozungulira amapangidwa m'magulu, ndipo zigawozo zimapanikizidwa kuti apange asungani.Chigawo chilichonse chimaphatikizapo mkuwa wokhazikika, womwe umapanga oyendetsa pamwamba pa gawo lililonse.
Kuthira kwa Copper:Madera a PCB omwe amadzazidwa ndi zigawo zazikulu zamkuwa.Madera awa akhoza kukhala owoneka modabwitsa.
Ma trace ndi mizere yopatsira:Mawuwa amagwiritsidwa ntchito mosiyana, makamaka pa ma PCB apamwamba kwambiri.
Signal motsutsana ndi gulu la ndege:Chosanjikiza cha ma sign chimapangidwa kuti chimangonyamula ma siginecha amagetsi, komanso chimatha kukhala ndi ma polygon amkuwa omwe amapereka pansi kapena mphamvu.Zigawo za ndege zimapangidwira kuti zikhale ndege zathunthu popanda zizindikiro.
Kudzera:Awa ndi mabowo ang'onoang'ono obowoledwa mu PCB omwe amalola kuti kutsata kusuntha pakati pa zigawo ziwiri.
Zigawo:Zimatanthawuza gawo lililonse lomwe limayikidwa pa PCB, kuphatikiza zida zoyambira monga zopinga, zolumikizira, mabwalo ophatikizika, ndi zina zambiri.Zigawo zimatha kukwera pogulitsidwa pamwamba (zigawo za SMD) kapena zotsogola zomwe zimagulitsidwa m'mabowo amkuwa (kudzera m'mabowo) pa bolodi yozungulira.
Mapadi ndi mabowo:Zonsezi zimagwiritsidwa ntchito kukwera zigawo ku bolodi la dera ndipo zimagwiritsidwa ntchito ngati malo opangira solder.
Silkscreen:Izi ndi zolemba ndi ma logos osindikizidwa pamwamba pa PCB.Izi zili ndi zidziwitso zamagawo azinthu, ma logo a kampani kapena manambala am'gawo, olemba mareferensi, kapena zina zilizonse zofunika pakupanga, kusonkhanitsa, ndi kugwiritsidwa ntchito pafupipafupi.
Othandizira:Izi zimauza wopanga ndi wophatikiza zigawo zomwe zimayikidwa m'malo osiyanasiyana pa bolodi ladera.Chigawo chilichonse chili ndi cholembera, ndipo okonza awa angapezeke m'mafayilo opangira pulogalamu yanu ya ECAD.
Soldermask:Uwu ndiye wosanjikiza wapamwamba kwambiri mu PCB womwe umapatsa gulu lozungulira mtundu wake (nthawi zambiri wobiriwira).
