3. Ulungelelwaniso loyilo ukwenzela imfezeko yomqondiso

Ingqibelelo yomqondiso ibalulekile ekusebenzeni ngokufanelekileyo koyilo lwePCB yakho. Ukwandisa imfezeko yesiginali, kubalulekile ukunikela ingqalelo kuyilo lwePCB. Beka amacandelo abalulekileyo ngokusondeleyo omnye komnye ukunciphisa ubude boqhagamshelwano lomkhondo kunye nokunciphisa ithuba lokuphazamiseka. Sebenzisa ngokufanelekileyo umhlaba kunye neenqwelomoya zamandla ukuphucula ingqibelelo yomqondiso kunye nokunciphisa ingxolo. Ngokuqinisekisa uyilo olulungiselelwe kakuhle, unokuphucula ukusebenza koyilo lwePCB yakho.

4. Nciphisa ingxolo kunye ne-crosstalk

Ingxolo kunye ne-crosstalk kuyilo lwe-PCB inokubangela ukuthomalalisa umqondiso kwaye ichaphazele ukusebenza ngokubanzi. Ukunciphisa ezi ngxaki, i-analog eyahlukileyo kunye neempawu zedijithali kwiileya ezahlukeneyo zePCB. Sebenzisa iindlela ezifanelekileyo zokumisa ukuthintela ukudityaniswa kwengxolo phakathi kweendlela zemiqondiso eyahlukeneyo. Sebenzisa ukhuselo kwaye ugcine isithuba esifanelekileyo phakathi kweetrayisi ezinovakalelo ukunciphisa i-crosstalk. Ngokunciphisa ingxolo kunye ne-crosstalk, unokufezekisa ngokucacileyo, imiqondiso ethembekileyo kuyilo lwePCB yakho.

5. Ukukhethwa kwecandelo kunye nokubekwa

Ukukhetha icandelo ngononophelo kunye nokubekwa kubalulekile kwiprototyping ye-PCB efanelekileyo. Khetha amacandelo anengcaciso efunekayo kwaye uqinisekise ukuba akulungele ukuveliswa. Cinga izinto ezifana nobukhulu becandelo, iimfuno zamandla, kunye nolawulo lobushushu ngexesha lokubekwa kwecandelo. Ngokukhetha ngobuchule kunye nokubeka amacandelo, unokunciphisa ukuphazamiseka komqondiso, imiba ye-thermal kunye nemingeni yemveliso.

6. Lungiselela inethiwekhi yokuhambisa amandla

Unikezelo lwamandla olusebenzayo lubalulekile ekusebenzeni ngokufanelekileyo koyilo lwePCB yakho. Yila uthungelwano losasazo lwamandla oluphuculweyo ukunciphisa ukuhla kwamandla ombane, ukunciphisa ilahleko yamandla, kunye nokuqinisekisa unikezelo lwamandla oluzinzileyo kumacandelo ahlukeneyo. Ubungakanani ngokufanelekileyo umkhondo amandla kunye vias ukusingatha langoku efunekayo ngaphandle ukuvelisa ubushushu obugqithisileyo. Ngokwandisa uthungelwano lonikezelo lwamandla, unokuphucula ukuthembeka kunye nokusebenza koyilo lwePCB yakho.

7. Uyilo lokwenziwa kunye nokudibanisa

Xa uyila iprototype ye-PCB, inkqubo yokuvelisa kunye nendibano kufuneka ithathelwe ingqalelo. Izikhokelo zoYilo lweManufacturability (DFM) zinceda ukuqinisekisa ukuba uyilo lwakho lunokwenziwa lula, ludityaniswe, kwaye luvavanywe. Landela iinkqubo ezisemgangathweni zeDFM ezifana nokugcina ucoceko olululo, ukunyamezelana kunye nemigaqo yecandelo. Ngoyilo lokwenziwa kokwenziwa, unokunciphisa iimpazamo zemveliso, unciphise iindleko, kwaye ukhawulezise inkqubo yeprototyping.

8. Yenza uvavanyo olucokisekileyo kunye nohlalutyo

Nje ukuba uyilo lwakho lwePCB lulungile, yenza uvavanyo olucokisekileyo kunye nohlalutyo ukuqinisekisa ukusebenza kwayo kunye nokusebenza kwayo. Sebenzisa izixhobo ezifana nesoftware yokulinganisa ukuhlalutya indlela uyilo oluziphatha ngayo phantsi kweemeko ezahlukeneyo. Yenza uhlalutyo lwengqibelelo yomqondiso, uhlalutyo lwe-thermal, kunye novavanyo lombane ukuchonga imiba enokubakho kwaye wenze uphuculo oluyimfuneko. Ngokuvavanya ngokubanzi kunye nokuhlalutya uyilo lwePCB yakho, unokuchonga kwaye ulungise naziphi na iziphene zoyilo ukuze usebenze kakuhle.
