Design robots nge eqinile PCB ibhodi ngaphandle kokucabangela ukuvikela i-PCB ekwehlulekeni kokudlidliza okubangelwa i-resonance yemishini. Lokhu kwehluleka kungaholela ezinkingeni ezinkulu ezinjengama-insulators aphukile nama-capacitors, ukunqanyulwa kwezinto, ukuqedwa kwezintambo ze-PCB, ukuqhekeka kwebala le-solder, ukubekwa kwebhodi le-PCB, amasekhethi amafushane kagesi nokunqanyulwa komgqomo wokugoqa. Ukuqeda lokhu kwehluleka, amabhodi wesifunda aphrintiwe aguquguqukayo ayadingeka.

Yini i-PCB eqinile eguquguqukayo?

Ibhodi lesifunda eliphrintiwe lapho amapuleti wesifunda aqinile futhi aguquguqukayo ahlanganiswe ndawonye ukuhlanganisa izingxenye ezingxenyeni eziqinile nezingxenye zokugoba esikhundleni sokuxhuma kwentambo. Ingxenye eqinile ingafana ne-PCB eqinile yendabuko, lapho izingxenye zingafakwa kuzo zombili izinhlangothi zebhodi futhi kungenziwa izingqimba eziningi zokuxhuma, kuyilapho ingxenye eguquguqukayo ingaxhunywa kuzendlalelo eziningi, kepha izingxenye zingafakwa ku-welding on ngoba ingxenye eguquguqukayo isetshenziselwa ukuxhuma kuphela phakathi kwezingxenye zesifunda eziqinile.

Ukuqeda izixhumi kusuka kumklamo kungenisa lezi zindawo ezilandelayo esifundeni: Ukudluliswa kwamasignali kusuka kolunye uhlangothi kuya kolunye ngaphandle kokulahleka noma i-jitter (umsindo) Susa izinkinga zokuxhuma njengoxhumana nabo ababandayo.Khulula isikhala futhi unciphise isisindo. Kwenza ukuvevezela kwesifunda futhi kungafakwa kuzinhlelo zokusebenza ezinezingxenye ezihambayo.

Idizayini eqinile ye-PCB:

Izinhlobo ezahlukahlukene zesoftware ziyatholakala ukuklama i-PCBS eqinile eguquguqukayo, kepha i-Altium inikeza ukubonwa okuhle kakhulu kwe-3D kwama-PCBS aqinile futhi kunconywa kakhulu. Lapho kuklanywa izingxenye eziqinile nezishintshashintshayo, kubaluleke kakhulu ukukhetha ububanzi bokulandela ithusi ngokuya ngohlelo lokusebenza.

Lokhu kukhombisa ukuthi inani elifanayo lamanje kumele lisetshenziswe ezingxenyeni eziqinile nezigobile ezinobubanzi obuhlukile bokulandela ngenxa yobukhulu, indawo nokuvunyelwa kwento. Onjiniyela beRayming PCB nabakwaMhlangano bahlala bekhona ukubonisana nobubanzi bezintambo ezifanele kanye nezinto ezithandekayo kumvamisa wakho wokusebenza nesicelo sakho.

Ukulinganisa kwe-PCB eguquguqukayo:

Imodeli yedoli yephepha ibaluleke kakhulu ekwakheni amasekethe aguquguqukayo. Lo mkhuba olula ungasiza abaklami ukuthi bavikele amaphutha amaningi ngokukhombisa izinkinga ezihlobene nokugoba kusenesikhathi, futhi kungonga isikhathi nemali. Lokhu kusiza umklami ukubikezela i-radius eguqa futhi akhethe indlela efanele yokuthola ithusi ukuvimbela ukudwengula noma ukuyeka ukusebenza.

Yakha umkhondo wethusi ngokuchema:

Ukugcina ithusi elengeziwe ekwakhiweni kukhulisa ukuzinza kobukhulu besekethe eliguquguqukayo. Kumiklamo eguquguqukayo yongqimba olulodwa futhi emaceleni amabili, ukuchema okuzungeze umkhondo wethusi kuwumkhuba omuhle. Ukwengezwa noma ukususwa kwethusi elengeziwe kuncike kuphela esicelweni, kepha uma umklami enethusi elengeziwe elinokuchema, imikhondo enokuchema kufanele isetshenziselwe ukuzinza komshini. Ngaphezu kwalokho, ukwenza njalo kunganciphisa inani le-etched yethusi, elilungele imvelo maqondana nokusetshenziswa kwamakhemikhali.

Isakhiwo esibophayo ekuguquguqukeni kwesendlalelo esiningi:

Idizayini yobude obudidiyelwe ivame ukusetshenziselwa ukwenza lula ukwakheka kwamasekethe aguquguqukayo amaningi. Kule ndlela, umklami ukhulisa kancane ubude besendlalelo ngasinye esiguquguqukayo esilandelayo, esivame ukuphinda izikhathi eziyi-1.5 ubukhulu besendlalelo ngasinye. Lokhu kuvimbela ukugoba okuphakathi nendawo koqweqwe olugobile kumjikelezo wesendlalelo esiguquguqukayo esinobubanzi obuhlukile. Ngale ndlela elula, ukukhishwa kwe-tensor kanye ne-i-beam effect okusungulwe kungqimba lwensimbi engaphandle kungaqedwa, okungaba inkinga enkulu kuzinhlelo ezinamandla.

Landelela izintambo zekhoneni:

Ezinye zezinkinga ezihambisana nokuhamba ngocingo kumasekethe aguquguqukayo kufaka phakathi ukugcina inani lokuwela lilinganiselwe ukuze izingqimba zinciphiswe ukonga imali, kanti okwesibili yi-Angle yokugoba yemikhondo ekwakhiweni kwesifunda okuguquguqukayo. Iminonjana kufanele igobeke futhi isongwe emakhoneni, ngoba amakhona acijile angabamba isixazululo ngesikhathi sokudonsa futhi angahle akhululeke futhi kuzoba nzima ukuwahlanza ngemuva kokwelashwa. Lapho kunemikhondo yethusi ohlangothini ngalunye lwesekethe eliguquguqukayo, umklami kufanele aklame isikhala esiphindwe ka-2-2.5 ububanzi bomugqa ukugwema noma isiphi isifunda esifushane sikagesi kanye nokufakwa ngendlela efanele. Ukucabanga ngale miyalo kungathuthukisa ukusakazwa kwesiginali futhi kunciphise ukubonakaliswa ngesikhathi sokujika.

Izingxenye eziguqukayo zokuguqa eziguqukayo:

Ibanga eliphansi ukusuka endaweni eguqukayo kuya eguquguqukayo yokushintshela onqenqemeni lomgodi wokuvula futhi ihlanganiswe ngomgodi ngeke ibe ngaphansi kwamasentimitha angu-0.0748. Lapho kuklanywa ibanga phakathi kokungafulelwanga ngembobo nangaphakathi nangaphandle kwemiphetho yokusika, okokugcina okusalayo akufanele kube ngaphansi kwamasentimitha angu-0.0197.

Ngesandla Esiqinile – ukuguquguquka kwesibonisi esibonakalayo ngembobo:

Ibanga eliphansi eliphakanyisiwe phakathi kwesigaba esiphambanweni esiqinile futhi lifakwe emigodini yesibonisi esibonakalayo esiguquguqukayo likhulu kuno-0.125 in. Ukwephula lo mthetho kungathinta ukwethembeka kwesingxobo ngomgodi.
