Kwishishini le-elektroniki, i ibhodi yesekethe eprintiweyo (PCB) lelona candelo liphambili kwiimveliso ezahlukeneyo zombane. Umgangatho we-soldering wamacandelo kwi-PCB uchaphazela ngokuthe ngqo ukusebenza kwemveliso. Ngoko ke, ukuhlolwa komgangatho kunye novavanyo lweebhodi zePCB lulawulo lomgangatho wabavelisi bezicelo ze-PCB. Ikhonkco eliyimfuneko. Okwangoku, uninzi lomsebenzi wokuhlola umgangatho we-PCB we-solder wenziwa ngokuhlolwa okubonakalayo okwenziwa ngesandla. Impembelelo yezinto zomntu kulula ukuyiphosa kwaye iqondwe phosakeleyo.

Ke ngoko, ishishini lePCB lifuna ngokungxamisekileyo ukuhlolwa okubonakalayo okuzenzekelayo kwi-intanethi, kwaye iimveliso zangaphandle zibiza kakhulu. Ngokusekelwe kule meko, ilizwe laqala ukuphuhlisa oku. Iinkqubo zokuFumana. Eli phepha ikakhulu lifunda ukuchongwa kweziphene zebhodi yePCB yokuwelda: ukuchongwa kokumelana neringi yombala, ukuchongwa kwecandelo lokuvuza kwe-welding kunye nokuchongwa kwe-capacitor polarity.

Indlela yokucubungula kweli phepha kukudibanisa indlela yothelekiso yereferensi kunye nendlela yothelekiso engabhekiseliyo ekufumaneni umfanekiso webhodi yePCB kwikhamera yedijithali, kwaye usebenzise iindlela zokubeka umfanekiso, ukulungiswa komfanekiso kunye nokuqondwa komfanekiso, ukutsalwa kwesici ukuqonda umsebenzi wokubona ngokuzenzekelayo. Ngovavanyo lwemifanekiso emininzi yePCB, indlela yokumisa yeempawu zePCB iyaphuculwa ukufumana indawo echanekileyo yomfanekiso.

Inxalenye esemgangathweni yokuqhekeka yinxalenye ebalulekileyo. Le yibhodi yesekethe kunye nebhodi eqhelekileyo. Yenza inyathelo lokuqala lomdlalo ochanekileyo. Kwinxalenye yokulungiswa komfanekiso, indlela entsha yokulungiswa kwejiyometri isetyenziselwa ukulungisa umfanekiso ukuze ufumane imifanekiso echanekileyo yePCB kunye nolungelelwaniso lwepixel oluchanekileyo lwecandelo ngalinye, kwaye wenze i-binarization yomfanekiso, ukuhluza okuphakathi, ukufunyanwa komphetho kunye nezinye iindlela zokufumana eyona Recognition. Kumfanekiso olandelayo wokuqatshelwa komfanekiso wesiphumo, iimpawu zikhutshwa kumfanekiso emva kokulungiswa kwangaphambili, kwaye iindlela ezahlukeneyo zokuqaphela zamkelwe iziphene ezahlukeneyo zokuwelda.

Ukusebenzisa iindlela zobalo ukukhupha amandla ombala osemgangathweni ukuchonga ngokuchanekileyo ukuxhathisa umsesane wombala, kunye nokusombulula ukuchongwa kokumelana nomsesane wombala ukusuka kwisahlulo sombala ukuya ekugcwalisweni okugcweleyo. Ngokumalunga neempawu zejometri ze-polar capacitor, indlela yokuchongwa kwejometri isetyenziselwa ukusetyenziswa kwe-welding yecandelo lokuvuza. Indlela yokuqaphela okunokwenzeka izuze iziphumo ezintle zokuqondwa. Ngoko ke, le ndlela inexabiso elihle lokukhangela ukuchongwa okuzenzekelayo kobhaqo lwesiphene kwi-PCB e-China.
