Njengengxenye ebalulekile yemishini ye-elekthronikhi, inqubo yokulungisa ye-PCBA idinga ukuhambisana ngokuqinile nochungechunge lwezicaciso zobuchwepheshe kanye nezidingo zokusebenza ukuze kuqinisekiswe ikhwalithi yokulungisa nokuzinza kwemishini. Lesi sihloko sizoxoxa ngokuningiliziwe amaphuzu adinga ukunakwa lapho PCBA ukulungisa kusuka izici eziningi, ngethemba lokuba usizo kubangani bakho.
1, Izidingo zokubhaka
Enqubweni yokulungiswa kwebhodi le-PCBA, ukwelashwa kokubhaka kubaluleke kakhulu.
Okokuqala, ukuze kufakwe izingxenye ezintsha, kufanele zibhakwe futhi zisuswe umswakama ngokuya ngezinga lokuzwela kwazo esitolo esikhulu kanye nezimo zokugcina, ngokuhambisana nezidingo ezifanele ze-“Code for the Use of moist-sensitive Components”, susa kahle umswakama ezingxenyeni futhi ugweme imifantu, ama-bubbles nezinye izinkinga ohlelweni lokushisela.
Okwesibili, uma inqubo yokulungisa idinga ukushiswa ibe ngaphezu kuka-110 ° C, noma kunezinye izingxenye ezizwela umswakama ezizungeze indawo yokulungisa, kuyadingeka futhi ukubhaka nokususa umswakama ngokuvumelana nezidingo zencazelo, engavimbela izinga lokushisa eliphezulu ukulimala ezingxenyeni futhi uqinisekise inqubekelaphambili ebushelelezi yenqubo yokulungisa.
Okokugcina, ezingxenyeni ezizwela umswakama ezidinga ukuphinda zisetshenziswe ngemva kokulungiswa, uma inqubo yokulungisa i-reflux yomoya oshisayo kanye namajoyini e-infrared heat solder isetshenziswa, kuyadingeka futhi ukubhaka nokususa umswakama. Uma inqubo yokulungisa ukushisa i-solder joint nge-manual soldering iron isetshenziswa, inqubo yokubhaka ngaphambilini ingashiywa ngesisekelo sokuthi inqubo yokushisa ilawulwa.
2.Izidingo zemvelo yesitoreji
Ngemuva kokubhaka, izingxenye ezizwela umswakama, i-PCBA, njll., kufanele futhi zinake indawo yokugcina, uma izimo zokugcina zidlula isikhathi, lezi zingxenye kanye namabhodi e-PCBA kufanele zibhakwe kabusha ukuze kuqinisekiswe ukuthi zisebenza kahle nokuzinza ngesikhathi. sebenzisa.
Ngakho-ke, lapho silungisa, kufanele sinake kakhulu izinga lokushisa, umswakama kanye neminye imingcele yendawo yokugcina ukuze siqinisekise ukuthi ihlangabezana nezidingo zokucaciswa, futhi ngesikhathi esifanayo, kufanele futhi sihlole ukubhaka njalo ukuvimbela ikhwalithi engaba khona. izinkinga.
3, Inombolo yokulungisa izidingo zokushisa
Ngokuya ngezidingo zokucaciswa, inani elihlanganisiwe lokushisisa kabusha kwengxenye ngeke lidlule izikhathi ezi-4, inani elivumelekile lokushisisa kabusha kwengxenye entsha ngeke lidlule izikhathi ezi-5, kanye nenani elivumelekile lokushisisa kabusha kokusetshenziswa kabusha okususiwe. ingxenye akufanele idlule izikhathi ezi-3.
Le mikhawulo isendaweni ukuze kuqinisekiswe ukuthi izingxenye kanye ne-PCBA azitholi umonakalo omkhulu uma kushisa izikhathi eziningi, okuthinta ukusebenza kwazo nokuthembeka. Ngakho-ke, inani lezikhathi zokushisa kufanele lilawulwe ngokuqinile phakathi nenqubo yokulungisa. Ngesikhathi esifanayo, ikhwalithi yezingxenye kanye namabhodi e-PCBA asondele noma adlula umkhawulo wemvamisa yokushisisa kufanele ihlolwe ngokucophelela ukuze kugwenywe ukuwasebenzisa ezingxenyeni ezibucayi noma okokusebenza okuthembeke kakhulu.
