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 yokulungiswa kufuneka ifudunyezwe ngaphezu kwe-110 ° C, okanye kukho ezinye izinto ezithintekayo zokufuma ngaphakathi kwe-5mm malunga nendawo yokulungisa, kufuneka ibhakwe ukuze isuse umswakama ngokwezinga lobuntununtunu kunye neemeko zokugcinwa kwamacandelo, kwaye ngokuhambelana neemfuno ezifanelekileyo zeKhowudi yokuSetyenziswa kweZiqendu eziSensitive.
Kwizinto ezibuthathaka zokufuma ezifuna ukuphinda zisetyenziswe emva kokulungiswa, ukuba inkqubo yokulungisa efana ne-reflux yomoya oshushu okanye i-infrared isetyenziselwa ukutshisa i-solder joints ngokusebenzisa iphakheji yecandelo, inkqubo yokususa ukufuma kufuneka yenziwe ngokomgangatho obuthathaka kunye nokugcinwa kweemeko zamacandelo kunye neemfuno ezifanelekileyo kwiKhowudi yokuSetyenziswa kweMicimbi ye-Sensitive Components. 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 aphinde asetyenziswe amacandelo asuswe phezulu angekho ngaphezu kwamaxesha e-3.
