PCBA ibhodi iya kulungiswa ngamaxesha athile, ukulungiswa kwakhona ikhonkco ebaluleke kakhulu, xa kukho impazamo encinane, kusenokukhokelela ngqo kwi scrap ibhodi ayikwazi ukusetyenziswa. Namhlanje izisa iimfuno zokulungisa iPCBA ~ masijonge!
Ekuqaleni,iimfuno zokubhaka
Onke amacandelo amatsha aza kufakelwa kufuneka abhakwe kwaye asuswe umswakama ngokwenqanaba elibuthathaka lokufuma kunye neemeko zogcino lwamalungu kunye neemfuno kwiNkcazo yoSetyenziso lwezahlulo ezibuthathaka zokufuma.
Ukuba inkqubo yokulungisa idinga ukufudumeza ngaphezu kwe-110 ° C, okanye kukho ezinye izinto ezithintekayo zokufuma ngaphakathi kwe-5mm malunga nendawo yokulungisa, kufuneka ibhakwe ukuze isuse umswakama ngokwenqanaba lobushushu kunye neemeko zokugcina zamacandelo, kwaye ngokuhambelana neemfuno ezifanelekileyo zeKhowudi yoSetyenziso lweMicimbi eSensitive ukufuma.
Kwizinto ezibuthathaka zokufuma ezifuna ukuphinda zisetyenziswe emva kokulungiswa, ukuba inkqubo yokulungisa efana ne-reflux yomoya oshushu okanye i-infrared isetyenziselwa ukufudumeza amalungu e-solder ngokusebenzisa iphakheji yecandelo, inkqubo yokususa ukufuma kufuneka yenziwe ngokuhambelana nebakala lokufuma kwaye iimeko zokugcina amacandelo kunye neemfuno ezifanelekileyo kwiKhowudi yokuSetyenziswa kweZixhobo ezibuthathaka zokufuma. Kwinkqubo yokulungisa usebenzisa i-ferrochrome yokufudumala i-solder joints, ukubhaka kwangaphambili kunokuphetshwa phantsi kwesiseko sokuba inkqubo yokufudumala ilawulwa.
Okwesibini, iimfuno zendawo yokugcina emva kokubhaka
Ukuba iimeko zokugcina amacandelo ukufuma ezibhakiweyo amacandelo, PCBA, kunye neekhomponenti unpacked amatsha ukuba endaweni idlula umhla wokuphelelwa, kufuneka ubhake kwakhona.
Okwesithathu, iimfuno zePCBA ukulungisa amaxesha okufudumeza
Ukufudumeza okuvumelekileyo kokusebenza kwakhona kwecandelo akuyi kudlula amaxesha ama-4; Amaxesha okufudumeza okuvumelekileyo okulungiswa kwamacandelo amatsha awayi kudlula amaxesha ama-5; Inani lamaxesha okuhlaziya avunyelwe ukuba asetyenziswe kwakhona amacandelo asuswe phezulu angekho ngaphezu kwamaxesha e-3.
