Ngokuphathelele umgaqo wokugcinwa kweebhodi zeesekethe ze-PCB, umatshini wokuthungatha oluzenzekelayo ubonelela ngokulula kwi-soldering yeebhodi zesekethe ye-PCB, kodwa iingxaki zihlala zivela kwinkqubo yokuvelisa iibhodi zesekethe ze-PCB, eziya kuchaphazela umgangatho we-solder.Ukuze kuphuculwe umphumo wovavanyo, kufuneka kwenziwe enye i-technical processing kwibhodi elungisiweyo phambi kovavanyo olusebenzayo lwe-intanethi yebhodi yesekethe ye-PCB ukunciphisa impembelelo yokuphazamiseka ngeendlela ezahlukeneyo kwinkqubo yovavanyo.Amanyathelo athile alandelayo:
.Ukulungiselela phambi kovavanyo
Ixesha elifutshane le-crystal oscillator (nikela ingqalelo kwi-oscillator ye-crystal ye-pin ukuze ufumanise ukuba zeziphi izikhonkwane ezimbini ziyizikhonkwane zokuvelisa umqondiso kwaye ziyakwazi ukujikeleza ezi zikhonkwane ezimbini. Khumbula ukuba ezinye izikhonkwane ezibini zizikhonkwane zamandla phantsi kweemeko eziqhelekileyo kwaye akufunekanga ibemfutshane-ijikelezwe!!) Kumthamo omkhulu we-electrolytic I-capacitor kufuneka ithengiselwe phantsi ukuze ivuleke.Ngenxa yokuba ukutshaja kunye nokukhutshwa kwee-capacitors zomthamo omkhulu kuya kubangela ukuphazamiseka.
2. Sebenzisa indlela yokukhutshwa ukuvavanya ibhodi yesekethe yePCB yesixhobo
Ngexesha lovavanyo lwe-intanethi okanye uvavanyo lokuthelekisa isixhobo, nceda uqinisekise ngokuthe ngqo isiphumo sovavanyo kwaye urekhode isixhobo esiphumelele uvavanyo (okanye siqhelekile).Ukuba uvavanyo aluphumeleli (okanye alunyamezeli), lunokuvavanywa kwakhona.Ukuba isasilela, unokuqinisekisa iziphumo zovavanyo kuqala.Oku kuqhubeka de isixhobo esisebhodini sivavanywe (okanye sithelekiswe).Emva koko jongana nezo zixhobo zingaphumeleli kuvavanyo (okanye ziphelelwe ukunyamezela).
Ezinye izixhobo zovavanyo zikwabonelela ngendlela engaphantsi ngokusesikweni kodwa esebenzayo ngakumbi yezixhobo ezingakwaziyo ukuphumelela uvavanyo lwe-intanethi lomsebenzi: kuba unikezelo lwamandla lwesixhobo sovavanyo kwibhodi yesekethe lunokusetyenziswa kunikezelo lwamandla oluhambelanayo kunye namandla ahambelanayo. unikezelo lwesixhobo ngekliphu yovavanyo.Ukuba i-pin yamandla yesixhobo inqunyulwe kwipini yomhlaba, isixhobo siya kunqunyulwa kwisistim sombane webhodi yesekethe.
Ngeli xesha, yenza uvavanyo olusebenzayo kwi-intanethi kwisixhobo;kuba ezinye izixhobo kwi-PCB aziyi kunikwa amandla okusebenza ukuphelisa isiphumo sophazamiseko, eyona mpembelelo yovavanyo ngeli xesha iya kulingana “novavanyo lwe-quasi-offline”.Izinga lokuchaneka liya kuba phezulu kakhulu.Uphuculo olukhulu.
