1-Ukusetyenziswa kweendlela ze-hybrid
Umthetho jikelele kukunciphisa ukusetyenziswa kweendlela zobugcisa zendibano kwaye zibeke umda kwiimeko ezithile. Umzekelo, izibonelelo zokufakwa kwicandelo elinye lokuhamba ngenqanawa (PT) ziphantse zabuyekezwanga ziindleko ezongezelelweyo kunye nexesha elifunekayo kwindibano. Endaweni yoko, ukusebenzisa izinto ezininzi ze-PT okanye ukushenxisa ngokupheleleyo kuyilo kukhetheka kwaye kufanelekile. Ukuba itekhnoloji ye-PT iyafuneka, kuyacetyiswa ukuba ihlawulwe yonke icandelo Vias kwelinye icala lesekethe elishicilelweyo, ngaloo ndlela kunciphisa ixesha elifunekayo lokuhlangana.

I-2 - Ubungakanani becandelo
Ngexesha lenqanaba loyilo lwePCB, kubalulekile ukukhetha ubungakanani bephakeji efanelekileyo yecandelo ngalinye. Ngokubanzi, kuya kufuneka ukhethe iphakheji encinci ukuba unesizathu esivakalayo; Ngaphandle koko, fudukela kwiphakheji enkulu. Ngapha koko, abalimi bobuqili bahlala bekhetha izinto neephakeji ezincinci ezingeyomfuneko, bedala iingxaki ezinokubakho ngexesha lesigaba sendibano kunye nokulungiswa kwesekethe. Kuxhomekeka kubungakanani botshintsho olufunekayo, kwezinye iimeko kunokuba lula ngakumbi ukudibanisa yonke iBhodi yonke kunokususa kwaye kuthengise izinto ezifunekayo.

I-3-indawo yendawo yokuhlala
Unyawo lwecandelo lelinye inkalo ebalulekileyo yendibano. Ke ngoko, abaqulunqi be-PCB kufuneka baqinisekise ukuba iphakheji nganye yenziwe ngokuchanekileyo ngokwendlela yomhlaba echazwe kwiphepha ledatha yecandelo ngalinye elidityanisiweyo. Eyona ngxaki iphambili ebangelwa kukuhamba kweenyawo ngokungachanekanga kukwenzeka kwe "thybsty Pof Preph", ekwabizwa ngokuba yimpembelelo ye-manzottan okanye i-agigan. Le ngxaki yenzeka xa icandelo elihlanganisiweyo lifumana ubushushu obungalinganiyo ngexesha lokuthengisa, kubangela ukuba icandelo elihlanganisiweyo linamathele kwi-PCB kwicala elinye kuphela. I-Cmbunomene yeTheNomenon ikakhulu ichaphazela izinto ze-SMD ezihamba njengabaqengqelekayo, amachaphaza, kunye nezikhundla. Isizathu sokwenzeka kwayo kukubethwa okungalinganiyo. Izizathu zezi zilandelayo:

Imilinganiselo yephepheni yomhlaba enxulumene necandelo ayichanekanga eyahlukileyo yeetreyi ezinxulumene neepads ezimbini zecandelo lobubanzi kakhulu, zisebenza njengodaka lobushushu.

I-4-Spiding phakathi kwezinto
Esona sizathu siphambili sokungaphumeleli kwe-PCB akukho ndawo yaneleyo phakathi kwezinto ezikhokelela ekuhambeni kakhulu. Isithuba sisixhobo esibalulekileyo, ngakumbi kwimeko yesekethe enzima kakhulu ekufuneka ihlangane neemfuno ezinzima kakhulu. Ukubeka icandelo elinye kufutshane nezinye izinto kunokwenza iintlobo ezahlukeneyo zeengxaki, ubukhulu becala ezinokuthi zifune utshintsho kumenzi we-PCB okanye inkqubo yokwenziwa, ukuchitha ixesha kunye nokuchitha iindleko.

Xa usebenzisa oomatshini bokusebenza ozenzekelayo kunye noomatshini bovavanyo, qinisekisa ukuba icandelo ngalinye likhulu ngokwaneleyo kumatshini oomatshini, kunye nemiphetho yebhodi yesekethe, kunye nawo onke amanye amacandelo. Izinto ezisondelelene kakhulu okanye zijikelezwe ngokungachanekanga zingumthombo weengxaki ngexesha lokumangalela. Umzekelo, ukuba icandelo eliphakamileyo linduluka icandelo lokuphakama eliphantsi ecaleni kwendlela elandelwa ngamaza, oku kunokwenza isiphumo "sesithunzi" esikhanyayo. Iisekethe ezihlanganisiweyo zajikeleza i-perpendicular enye kwenye ziya kuba nefuthe elifanayo.

Uluhlu lweCandelo eli-5
Ibhili yamacandelo (i-BOM) yinto ebaluleke kakhulu kuYilo lwePCB kunye namanqanaba eNdibano. Ngapha koko, ukuba i-BOM ineempazamo okanye ukungachaneki, umenzi unokumisa iSigaba seNdibano de le micimbi isonjululwe. Enye indlela yokuqinisekisa ukuba i-BOM ihlala ichanekile kwaye ihlaziyiwe kukwenza uphononongo olucokisekileyo lwe-BOM ngalo lonke ixesha uyilo lwe-PCB luhlaziywa. Umzekelo, ukuba into entsha yongezwa kwiprojekthi yoqobo, kufuneka uqinisekise ukuba i-BOM ihlaziyiwe kwaye iyahambelana ngokungenisa inombolo echanekileyo, inkcazo kunye nexabiso.

I-6-Ukusetyenziswa kweendawo zedatha
Amanqaku e-Fuminial, ekwabizwa ngokuba ngamanqaku e-Fudual, yimilo yobhedu ejikelezileyo esetyenziswa njengemidlalo yomatshini wendibano kunye nendawo. I-FIDUCEMS Yenza ukuba lo matshini oomatshini abazenzekelayo bakwazi ukuqaphela isifundo seBhodi kwaye baqokelelene ngokuchanekileyo intaba ye-qitsi ye-quad (i-qfp), i-qfp), i-BGP ye-BREAT (QFN).

I-fiducts yahlulwe yangamacandelo amabini: Imakishi ye-FIDUCIVER kunye nabamakishi basekhaya. Amanqaku e-Fintuctual AMANQAKU AQHUTYWA KUPHELA KWEEMPAWU ZE-PCB, ukuvumela umatshini wokukhetha kunye nokubeka oomatshini bokufumana i-shorintation yeBhodi kwindiza ye-Xy. Amanqaku e-Fudual Ark ebezibekwe kufutshane neekona ze-SMD ze-SMD esetyenziswa ngumatshini wokubekwa kwindawo yokubeka ngaselunxwemeni lomhlaba, ngaloo ndlela kuncitshiswa iimpazamo ezivakalayo ngexesha lendibano. Amanqaku e-datum adlala indima ebalulekileyo xa iprojekthi inezinto ezininzi ezisondeleyo komnye nomnye. Umzobo 2 ubonakalisa iBhodi ye-Arduine ye-Arduine ye-Arduine kunye neendawo ezimbini zesalathiso se-jikelele ezigxininiswa ebomvu.
