Embonini ye-elekthronikhi, i ibhodi yesifunda ephrintiwe (PCB) iyingxenye eyinhloko yemikhiqizo ehlukahlukene ye-elekthronikhi. Izinga le-soldering lezinto eziku-PCB lithinta ngqo ukusebenza komkhiqizo. Ngakho-ke, ukuhlolwa kwekhwalithi nokuhlolwa kwamabhodi e-PCB ukulawula ikhwalithi yabakhiqizi bezicelo ze-PCB. Isixhumanisi esibalulekile. Okwamanje, umsebenzi omningi wokuhlolwa kwekhwalithi ye-PCB wenziwa ngokuhlolwa okubonakalayo okwenziwa ngesandla. Ithonya lezici zomuntu kulula ukuligeja futhi ulibone ngokungeyikho.

Ngakho-ke, imboni ye-PCB idinga ngokushesha ukuhlolwa okubonakalayo okuzenzakalelayo okuku-inthanethi, futhi imikhiqizo yangaphandle ibiza kakhulu. Ngokusekelwe kulesi simo, izwe laqala ukuthuthukisa lokhu. Amasistimu Wokuthola. Leli phepha licwaninga ngokuyinhloko ukuhlonza iziphambeko zokushisela ibhodi le-PCB: ukuhlonza ukumelana nendandatho yombala, ukuhlonza ingxenye yokuvuza kokushisela kanye nokuhlonza i-capacitor polarity.

Indlela yokucubungula kuleli phepha iwukuhlanganisa indlela yokuqhathanisa ireferensi kanye nendlela yokuqhathanisa okungezona ireferensi ukuze uthole isithombe sebhodi le-PCB ekhamera yedijithali, futhi usebenzise izindlela zokubeka isithombe, ukucubungula kusengaphambili isithombe nokuqashelwa kwesithombe, ukukhishwa kwesici ukuze kubonakale umsebenzi wokuthola okuzenzakalelayo. Ngokuhlolwa kwezithombe eziningi ze-PCB, indlela yokubeka izici zesithombe se-PCB iyathuthukiswa ukuze kutholwe ukuma kwesithombe okunembile.

Ingxenye emisiwe yokuhlukaniswa iyingxenye ebalulekile. Leli yibhodi lesifunda kanye nebhodi elijwayelekile. Yenza isinyathelo sokuqala sokufanisa ncamashi. Engxenyeni yokucubungula ngaphambili kwesithombe, indlela entsha yokulungiswa kwejiyomethri isetshenziswa ukulungisa isithombe ukuze kutholwe izithombe ezinembile ze-PCB kanye nezixhumanisi ze-pixel ezinembayo zengxenye ngayinye, futhi kwenziwe ukuhlanganisa izithombe ngabili, ukuhlunga okumaphakathi, ukutholwa konqenqema nezinye izindlela zokuthola Ukuqashelwa okungcono kakhulu. Esithombeni esilandelayo sokuqashelwa kwesithombe somphumela, izici zikhishwa esithombeni ngemva kokucubungula kusengaphambili, futhi kwamukelwa izindlela ezihlukene zokuqaphela izinkinga ezihlukene zokushisela.

Ukusebenzisa izindlela zezibalo ukuze kukhishwe amandla ombala ajwayelekile ukuze kukhonjwe ngokunembile ukumelana nendandatho yombala, futhi kuxazululwe ukuhlonza ukumelana nendandatho yombala ukusuka ekuhlukaniseni umbala ukuya ekugcwalisweni okugcwele. Ngokuphathelene nezici zejometri ze-polar capacitor, indlela yokuhlonza i-geometric isetshenziswa ekusetshenzisweni kwe-welding yengxenye yokuvuza. Indlela yokuqaphela okungenzeka izuze imiphumela emihle yokuqashelwa. Ngakho-ke, le ndlela inenani elihle eliyireferensi lokuhlonza okuzenzakalelayo kokutholwa kokukhubazeka kwe-PCB e-China.
