ngokuthuthukiswa kobuchwepheshe be-elekthronikhi, amabhodi wesifunda asetshenziswa kakhulu emikhakheni ehlukahlukene, cishe wonke amadivaysi kagesi anamabhodi wesifunda.Izimoto ezisezingeni eliphezulu, ezondiza, i-elekthronikhi yezokwelapha, ikhaya elihlakaniphile elivamile, i-electronics yokuxhumana, izinto zikagesi zasendlini, njll. izinga lokushisa lokugcina kanye nomswakama kanye nendlela yokugcina.
Izinga lokushisa lesitoreji sebhodi le-PCB kanye nomswakama
Izinyathelo zokukhiqiza ibhodi le-PCB, kanye nezidingo zisegumbini elihlanzekile lokusebenza, ngakho-ke ukukhiqizwa kwe-pcb emvelweni kanye nezimfuneko zokushisa nomswakama ziqinile.Ukushisa nomswakama akufanelekile, kuzoholela ekugqwaleni kwebhodi le-pcb, kunciphise impilo yesifunda futhi kunciphise ukusebenza kwebhodi.Ngakho-ke ibhodi le-pcb kufanele ligcinwe endaweni yokugcina yokushisa: 22-27 degrees, umswakama: 50-60%.
Ibhodi le-PCB ligcina kanjani nesikhathi sokugcina
1. Ukukhiqizwa kwe-PCB nokucutshungulwa, kufanele kube ngokokuqala ngqa ukusebenzisa ukupakisha kwe-vacuum, futhi isikhwama sokupakisha se-vacuum kufanele sibe ne-desiccant kanye nokupakisha okuqinile, ayikwazi ukuxhumana namanzi nomoya, ukugwema ibhodi lesifunda se-pcb ebusweni be-spray tin kanye ne-pad bit is oxidation kuthinta i-welding kanye nekhwalithi yomkhiqizo.
2. Amabhodi e-PCB kufanele ahlungwe futhi alebulwe, amabhokisi avaliwe kufanele ahlukaniswe odongeni, akufanele abekwe endaweni yokukhanya kwelanga, ukuze agcinwe ekhabetheni lokugcina elinomoya futhi elomile elinendawo enhle yokugcina (izinga lokushisa: 22-27 degrees, umswakama. : 50-60%).
3. Isikhathi eside asizange sisetshenziswe pcb wesifunda ibhodi, the best in the period of the surface shayela ezintathu anti-varnish, umswakama-ubufakazi, uthuli-ubufakazi, anti-oxidation, ngakho pcb wesifunda ibhodi isitoreji ukuphila kungandiswa kube izinyanga ezingu-9.
4. Isiqephu se-pcb esingapakishiwe siqedwe endaweni yokushisa engaguquki kanye nomswakama wokulondoloza isikhathi esiyizinsuku eziyi-15, hhayi izinsuku ezingaphezu kwezingu-3 ekamelweni lokushisa.
5. I-pcb engapakishiwe kufanele isetshenziswe kungakapheli izinsuku ezi-3, ingasetshenzisiwe kuze kusetshenziswe kabusha izikhwama ezimile vacuum evalwe.
6. SMT patch kanye DIP ngemva ibhodi pcb ukuba zithuthwe futhi ibekwe nge ubakaki anti-static.
