Ngamafutshane, i-PCB ye-Bare ibhekisa kwiBhodi yeSiphako eprintiweyo ngaphandle komngxunya okanye kwizinto ze-elektroniki. Zihlala zibizwa ngokuba zii-PCB ze-bare kwaye ngamanye amaxesha zibizwa ngokuba zii-PCBS. Ibhodi ye-PCB engenanto inemijelo esisiseko, iipateni, i-rating caides kunye ne-PCB.

Yintoni ukusetyenziswa kweBhodi yePCB ye-PCB?
I-PCB ye-Bare yi-skeleton yebhodi yesekethe. I-IT ikhokela okwangoku kwaye ingoku kwiindlela ezifanelekileyo kwaye isetyenziswa kwizixhobo zekhompyuter ezininzi.

Ukulula kwePCB engenanto ibonelela ngeenjineli kunye nabaqulunqi kwinkululeko eyoneleyo yokongeza izinto njengoko kufuneka. Le bhodi engenanto ibonelela ngokutshintsha kwaye isebenze ukuba imveliso yobuninzi.

Ibhodi ye-PCB ifuna umsebenzi woyilo oluninzi kunezinye iindlela ze-wiring, kodwa zihlala zihamba ngokuzenzekelayo emva kwendibano kunye nemveliso. Oku kwenza ukuba i-PCB iBhodi ye-PCB iphantsi kwaye iphumelele impumelelo.

Ibhodi engenanto iluncedo kuphela emva kongeza izinto. Eyona njongo yokugqibela ye-pcb ye-bare yiba yibhodi yesekethe epheleleyo. Ukuba ihambelana nezinto ezifanelekileyo, ziya kuba nezinto ezininzi.

Nangona kunjalo, ayisiyiyo kuphela ukusetyenziswa kweebhodi zePCB. I-PCB engenanto yelona nqanaba lilungileyo ukwenza uvavanyo lwebhodi yebhodi yebhodi yebhodi yesekethe. Kubalulekile ukuthintela iingxaki ezininzi ezinokubakho kwixesha elizayo.
Kutheni le nto uvavanyo lweBhodi?
Zininzi izizathu zovavanyo lweebhodi ezingenanto. Njengekhefu lebhodi yebhodi yesekethe, ukusilela kwebhodi ye-PCB emva kokufakwa kuya kubangela iingxaki ezininzi.

Nangona ixhaphakile, i-PCB ye-Bare inokuthi sele ineziphene ngaphambi kongeze izinto. Iingxaki ezixhaphakileyo zigqithisi ngaphezulu, i-etching kunye nemingxunya. Nokuba iziphene ezincinci zinokubangela ukusilela ukwenza izinto.

Ngenxa yonyuso kwicandelo lecandelo, imfuno yeBhodi yePCB ye-PCB iyaqhubeka ikhula, ukwenza uvavanyo lwebhodi olungenanto lubaluleke ngakumbi. Emva kokudibana nePCB ye-Mulb, nje ukuba isilele senzeka, phantse ayinakwenzeka ukuyilungisa.

Ukuba i-PCB ye-Bare ye-Bare yithambo leBhodi yeSiphaluka, amacandelo ngamalungu kunye nemisipha. Izinto zinokubiza kakhulu kwaye zihlala zigxeka, ke ekuhambeni kwexesha, ukuba nesakhelo esomeleleyo sinokuthintela izinto ezinesiphelo esiphezulu ekuchithweni.

Iindidi zovavanyo lwebhodi engenanto
Ungazi njani ukuba i-PCB yonakele?
Oku kufuneka kuvavanywe ngeendlela ezimbini ezahlukeneyo: Umbane kunye nokuxhathisa.
Uvavanyo lweBhodi olungenanto luqwalasele lodwa kunye nokuqhubeka konxibelelwano lombane. Uvavanyo lovavanyo lodwa Unxibelelwano phakathi konxibelelwano olubini olwahlukileyo, ngelixa uvavanyo lokuqhubeka lujonga ukuqinisekisa ukuba akukho manqaku avulekileyo anokuphazamisana.
Nangona uvavanyo lombane luxhaphakile, uvavanyo lokuxhathisa aluqhelekanga. Ezinye iinkampani ziya kusebenzisa indibaniselwano yezi zinto zimbini, endaweni yokusebenzisa uvavanyo olunye.
Uvavanyo lokuxhathisa thumela okwangoku ngomqhubi ukuba alinganise ukunganyangeki. Unxibelelwano olude okanye olucekeceke luya kuvelisa ukumelana okukhulu kunomphakamo omfutshane okanye oqinileyo.
Uvavanyo lweBatch
Kwimveliso enenqanaba elithile leprojekthi, abavelisi beBhodi yeBhodi yeBhodi yeSiphaluka baya kuzisebenzisa ngokuBanzi ngokuBanzi boVavanyo, babizwa ngokuba "zii-racks zovavanyo." Olu vavanyo lusebenzisa izikhonkwane ezilayishwe ngentwasahlobo ukuvavanya yonke indawo kwi-PCB.
Uvavanyo lokulinganisa oluzinzileyo lusebenza kakhulu kwaye lunokugqitywa kwimizuzwana nje embalwa. Eyona nto igwenxa kakhulu ziindleko eziphezulu kunye nokusilela kokuguquguquka. Uyilo olwahlukileyo lwe-PCB lufuna i-finxtutions ezahlukeneyo kunye nezikhonkwane (ezifanelekileyo kwimveliso yobuninzi).
Uvavanyo lwePrototype
Uvavanyo lweProphang Probe lusetyenziswa ngokubanzi. Iingalo ezimbini zerobhothi ezinee-RODS zisebenzisa inkqubo yesoftware yokuvavanya uqhagamshelo lweBhodi.
Xa kuthelekiswa novavanyo olukhawulezileyo lokulinganisa, kuthatha ixesha elinde, kodwa kuyafikeleleka kwaye kube ngathi bhetyebhetye. Ukuvavanywa kuyilo olwahlukileyo kulula njengokufaka ifayile entsha.

Izibonelelo zovavanyo lweBhodi engenanto
Uvavanyo lweBhodi olungenanto lunezibonelelo ezininzi, ngaphandle kokungalunganga. Eli nyathelo lenkqubo yokuphucula inokuphepha iingxaki ezininzi. Isixa esincinci sotyalo-mali kwinqanaba lokuqala linokugcina ulondolozo oluninzi kunye neendleko zokutshintsha.

Uvavanyo lwebhodi olungenanto lunceda ukufumana iingxaki kwangoko kwinkqubo yokuphucula. Ukufumana ingxaki kwangethuba kuthetha ukufumana unobangela wengxaki kwaye ukwazi ukusombulula ingxaki kwingcambu yayo.

Ukuba ingxaki ifunyenwe kwinkqubo elandelayo, kuya kuba nzima ukufumana ingxaki yengcambu. Nje ukuba iBhodi ye-PCB igutyungelwe ngamacandelo, akunakwenzeka ukufumanisa ukuba yintoni ebangele ingxaki. Uvavanyo lwakwangoko luyanceda ukulungisa ingxaki unobangela.

Uvavanyo kwakhona luyenza lula inkqubo yonke. Ukuba iingxaki zifunyenwe kwaye zisonjululwe ngexesha lesigaba sophuhliso lweProttype, izigaba zemveliso ezilandelayo zinokuqhubeka ngaphandle kwesithintelo.

Gcina ixesha leProjekthi kuvavanyo lweBhodi engenanto

Emva kokwazi ukuba yintoni iBhodi engenayo, kunye nokuqonda ukubaluleka kovavanyo lwebhodi yeBhodi. Uya kufumanisa ukuba nangona inkqubo yokuqala yeprojekthi iyacotha ngenxa yovavanyo, ixesha eligcinwe ngovavanyo lwebhodi ye-Bare kuyo le projekthi. Ukwazi ukuba zikho iimpazamo kwi-PCB zingenza ukuba kubekho iingxaki emva koko.

Inqanaba lokuqala lelona xesha lisebenzayo kakhulu lovavanyo lwebhodi engenanto. Ukuba iBhodi yePakethi yesekethe ehlanganisiweyo iyasilela kwaye ufuna ukuyilungisa kwangoko, iindleko zelahleko zinokuba ngaphezulu kwamaxesha aphezulu.

Nje ukuba ibala linengxaki, amathuba okubaleka kwayo kuya kuphakama kabukhali. Ukuba izinto ezibizayo zithengiselwe kwi-PCB, ilahleko iya kukhula ngakumbi. Ke ngoko, yeyona nto imbi kakhulu ukufumana impazamo emva kokuba ibhodi yesekethe ihlanganisene. Iingxaki ezifunyenwe ngeli xesha zihlala zikhokelela ekufumaneni yonke imveliso.

Ngophuculo olusebenzayo kunye nokuchaneka kubonelelwe luvavanyo, kufanelekile ukuqhuba uvavanyo lweBhodi engenabantu kwinqanaba lokuqala lemveliso. Emva kwayo yonke loo nto, ukuba iBhodi yesekethe yokugqibela iyasilela, amawaka amanye amawaka anokuchithwa.
