PCBA ibhodi ngezikhathi ezithile izokhandwa, ukukhanda ubuye isixhumanisi esibaluleke kakhulu, uma kukhona iphutha elincane, kungase kuholele ngqo scrap ibhodi ayikwazi ukusetshenziswa. Namuhla kuletha izidingo zokulungisa i-PCBA ~ ake sibheke!
Okokuqala,izidingo zokubhaka
Zonke izingxenye ezintsha ezizofakwa kufanele zibhakwe futhi zisuswe umswakama ngokuvumelana nezinga elizwelayo lomswakamo kanye nezimo zokugcina zezingxenye kanye nezidingo Ezikucacisweni Kokusetshenziswa Kwezingxenye Ezizwela Umswakama.
Uma inqubo yokulungisa idinga ukushiswa ngaphezu kwe-110 ° C, noma kunezinye izingxenye ezizwela umswakama ngaphakathi kwe-5mm ezungeze indawo yokulungisa, kufanele ibhakwe ukuze kukhishwe umswakama ngokwezinga lokuzwela komswakama kanye nezimo zokugcina zezingxenye, futhi ngokuhambisana nezidingo ezifanele zeKhodi Yokusetshenziswa Kwezingxenye Ezizwela Umswakama.
Ezingxenyeni ezizwela umswakama ezidinga ukuphinda zisetshenziswe ngemuva kokulungiswa, uma inqubo yokulungisa efana ne-hot air reflux noma i-infrared isetshenziselwa ukushisa amalunga e-solder ngephakheji lengxenye, inqubo yokususa umswakama kufanele yenziwe ngokuya ngebanga elizwela umswakama futhi izimo zokugcina zezingxenye kanye nezidingo ezifanele kwiKhodi Yokusetshenziswa Kwezingxenye Ezizwela Umswakama. Ukuze inqubo yokulungisa isebenzisa ama-solder e-ferrochrome okushisa ahlangene, ukubhaka kwangaphambili kungagwenywa ngaphansi kwesisekelo sokuthi inqubo yokushisa ilawulwa.
Okwesibili, izidingo zemvelo yokugcina emva kokubhaka
Uma izimo zokugcinwa kwezingxenye ezibucayi zomswakama obhakiwe, i-PCBA, kanye nezingxenye ezintsha ezingapakishwayo ezizoshintshwa zidlula usuku lokuphelelwa yisikhathi, udinga ukuzibhaka futhi.
Okwesithathu, izidingo PCBA ukulungisa Ukushisa izikhathi
Ukushisa okuphelele okuvunyelwe kokusebenza kabusha kwengxenye akufanele kudlule izikhathi ezi-4; Izikhathi zokushisa zokulungiswa kabusha ezivumelekile zezingxenye ezintsha akumele zidlule izikhathi ezi-5; Inombolo yezikhathi zokushisisa kabusha ezivunyelwe ukuze zisetshenziswe kabusha izingxenye ezikhishwe phezulu azidluli izikhathi ezi-3.
