1. Kukonzekera
Kuphatikizirapo kukonzekera zigawo za library ndi schematics.Mapangidwe a PCB asanachitike, konzani kaye laibulale yachigawo cha SCH ndi laibulale yamagulu a PCB.
Laibulale ya phukusi la PCB imakhazikitsidwa bwino ndi mainjiniya kutengera chidziwitso cha kukula kwa chipangizo chomwe mwasankha.M'malo mwake, yambitsani laibulale ya gawo la PC, kenako yambitsani laibulale yachigawo cha SCH.
PCB chigawo phukusi laibulale ndi wovuta kwambiri, zimakhudza mwachindunji PCB unsembe;schema SCH gawo laibulale zofunika laibulale ndi momasuka, koma tcherani khutu ku matanthauzo abwino pini katundu ndi makalata ndi PCB chigawo laibulale phukusi.
2. PCB kapangidwe kamangidwe
Malingana ndi kukula kwa bolodi kwatsimikiziridwa ndi maonekedwe osiyanasiyana amakina, malo opangira PCB kuti ajambule chimango cha bolodi la PCB, ndikuyika zofunikira kuti aike zolumikizira zofunika, makiyi / masiwichi, mabowo owononga, mabowo a msonkhano, ndi zina zotero.
Ganizirani mozama ndikuzindikira malo opangira mawaya ndi malo osagwirizana ndi mawaya (monga kuchuluka kozungulira bowo la screw komwe kuli malo osagwirizana).
3. PCB kamangidwe kamangidwe
Mapangidwe a masanjidwe ndi kuyika kwa zida mu PCB chimango molingana ndi kapangidwe kake.Pangani tebulo la netiweki mu chida chokonzera (Design→CreateNetlist), ndiyeno lowetsani tebulo la netiweki mu pulogalamu ya PCB (Design→ImportNetlist).Pambuyo kuitanitsa bwino kwa tebulo la intaneti lidzakhalapo kumbuyo kwa pulogalamuyo, kupyolera mu Kuyika ntchito kungakhale zipangizo zonse zomwe zimatchedwa, pakati pa zikhomo ndi nsonga zowuluka zolumikizidwa, ndiye kuti mukhoza kupanga mapangidwe a chipangizocho.
Mapangidwe a masanjidwe a PCB ndiye njira yoyamba yofunikira pamapangidwe onse a PCB, gulu la PCB lovuta kwambiri, momwe masanjidwewo angakhudzire mwachindunji kukhazikika kwa mawaya amtsogolo.
Mapangidwe amapangidwe amadalira luso loyambira la wokonza dera komanso luso la kapangidwe kake, wopanga ma board ndi apamwamba kwambiri pazofunikira.Opanga ma board board a achichepere akadali ozama, oyenera kupanga ma module ang'onoang'ono kapena bolodi lonse silikhala lovuta pakupanga ma PCB.
4. PCB wiring design
PCB mawaya mapangidwe ndi ntchito yaikulu kwambiri mu lonse PCB mapangidwe ndondomeko, amene mwachindunji amakhudza ntchito ya bolodi PCB.
Pakupanga kwa PCB, mawaya nthawi zambiri amakhala ndi magawo atatu.
Choyamba, nsalu kudzera, chomwe chili chofunikira kwambiri cholowera pamapangidwe a PCB.
Kachiwiri, ntchito magetsi kukumana, umene ndi muyeso ngati PCB bolodi oyenerera miyezo, pambuyo mzere kudzera, mosamala kusintha mawaya, kuti akwaniritse bwino ntchito magetsi.
Apanso ndi waudongo ndi wokongola, wosokonekera mawaya, ngakhale ntchito magetsi adzabweretsanso vuto lalikulu kukhathamiritsa kenako kukhathamiritsa bolodi ndi kuyezetsa ndi kukonza, mawaya amafuna mwaukhondo ndi mwaudongo, sangathe crisscrossed popanda malamulo ndi malamulo.
5. Kukhathamiritsa kwa ma waya ndikuyika silkscreen
"Mapangidwe a PCB si abwino kwambiri, abwinoko", "mapangidwe a PCB ndi luso lopanda pake", makamaka chifukwa mapangidwe a PCB kuti akwaniritse zosowa zamagulu osiyanasiyana a hardware, ndipo zosowa za munthu aliyense zingakhale zotsutsana pakati pa nsomba ndi chimbalangondo cha chimbalangondo. paw sangakhale onse awiri.
Mwachitsanzo: PCB kapangidwe polojekiti pambuyo pa bolodi mlengi kuwunika kufunika kupanga 6-wosanjikiza bolodi, koma mankhwala hardware kuganizira mtengo, zofunika ziyenera kupangidwa ngati bolodi 4-wosanjikiza, ndiye kokha pa ndalama za chizindikiro chishango pansi wosanjikiza, kuchititsa kuwonjezeka chizindikiro crosstalk pakati pa zigawo moyandikana mawaya, khalidwe chizindikiro adzachepetsedwa.
Zomwe zimapangidwira ndi izi: kukhathamiritsa nthawi ya mawaya ndikuwirikiza kawiri nthawi yoyambira.PCB mawaya kukhathamiritsa watha, kufunika pambuyo processing, processing chachikulu ndi PCB bolodi pamwamba pa silika chophimba chizindikiro, kamangidwe ka wosanjikiza pansi wa zilembo silika chophimba ayenera kuchita galasi processing, kuti kusokoneza ndi pamwamba wosanjikiza silika-screen.
6. Network DRC cheke ndi dongosolo fufuzani
Kuwongolera kwaubwino ndi gawo lofunikira pakupanga mapangidwe a PCB, njira zambiri zowongolera khalidwe zimaphatikizansopo: kudziyang'anira nokha, kuyang'anirana kwapang'onopang'ono, misonkhano yowunikira akatswiri, kuwunika kwapadera, ndi zina zambiri.
Chiwembu ndi structural zinthu za chithunzi ndi zofunika kwambiri kamangidwe amafuna, maukonde DRC cheke ndi dongosolo fufuzani ndi kutsimikizira kuti PCB kapangidwe kukumana netlist schematic ndi zinthu structural wa chithunzi cha zinthu ziwiri athandizira.
Opanga ma board agulu azikhala ndi macheke awoawo omwe amadziunjikira, omwe ndi gawo lazolemba zakampani kapena dipatimenti, gawo lina kuchokera kuzidule za zomwe adakumana nazo.Macheke apadera amaphatikiza kapangidwe ka cheke cha Valor ndi DFM, magawo awiriwa akukhudzidwa ndi mapangidwe a PCB omwe amapangidwa kumbuyo kumapeto kwa fayilo yojambula.
7. PCB board kupanga
Mu PCB processing yovomerezeka pamaso pa bolodi, dera mlengi gulu ayenera kulankhula ndi PCB A katundu bolodi fakitale PE, kuyankha Mlengi pa PCB bolodi processing nkhani chitsimikiziro.
Izi zikuphatikizapo, koma si zokhazo: kusankha PCB bolodi mtundu, mzere m'lifupi mzere katayanitsidwe kusintha kwa mzere wosanjikiza, impedance ulamuliro kusintha, PCB lamination makulidwe kusintha, pamwamba mankhwala processing ndondomeko, dzenje kulolerana ulamuliro ndi mfundo yobereka.
