Izingxenye ze-elekthronikhi ziyizinto eziyinhloko zokucutshungulwa kwe-chip, ezinye izakhi kanye nezinhlobonhlobo ezivamile, zidinga isitoreji esikhethekile ukuze kuqinisekiswe ukuthi azikho izinkinga, izinga lokushisa kanye nomswakama izingxenye ezibucayi kungenye yazo.Izinga lokushisa kanye nomswakama isitoreji sokuphatha izingxenye ezibucayi enqubweni yokucubungula kubaluleke kakhulu, kuzothinta ngqo ikhwalithi yokucubungula kwe-PCBA.Ekuqinisekiseni ukucubungula kwe-smt SMD lapho ukusetshenziswa okufanele kwezinga lokushisa nomswakama izingxenye ezibucayi, ukuvimbela izingxenye ngomswakama wemvelo, umswakama kanye nokusetshenziswa kwezinto zokupakisha eziphikisana ne-static, amaphuzu alandelayo angaba ukulawula okuphumelelayo kokuphatha, ukugwema ukulawula okungalungile kwezinto futhi kuthinte ikhwalithi.
Izindlela zokuphatha ezintathu ezilandelayo kusukela kokulandelayo ukuhlaziya okulandelayo
Ukuphathwa kwemvelo
Ukuphathwa kwenqubo
Umjikelezo wokulondoloza ingxenye
I. Ukuphathwa kwemvelo (izingxenye zesitoreji ezizwela ukuswakama kwezimo zemvelo)
I-General PCBA processing factory izothuthukisa uhlelo lokulawula izinga lokushisa nomswakama izingxenye ezizwelayo, izinga lokushisa lendawo yokusebenzela kufanele lilawulwe ku-18 ℃ -28 ℃.Endaweni yokugcina, izinga lokushisa kufanele lilawulwe ku-18℃-28℃ kanye nomswakama ohlobene ngaphansi kuka-10%.Ukuze kugcinwe izinga lokushisa kanye nomswakama endaweni evaliwe yefektri, isikhala akufanele sishiywe sivulekile noma sivuliwe isikhathi esingaphezu kwemizuzu emi-5.
Abasebenzi bezinto ezibonakalayo njalo emahoreni angu-4 ukuze bahlole izinga lokushisa lebhokisi elivikela umswakama kanye nomswakama, izinga lokushisa lalo kanye nenani lomswakamo elibhaliswe “kuthebula lokulawula izinga lokushisa nokuswakama”;uma izinga lokushisa nomswakama kudlula ibanga elishiwo, yazisa ngokushesha izisebenzi ezifanele ukuthi zithuthuke, kuyilapho uthatha izinyathelo ezifanele zokulungisa (njengokubeka i-desiccant, ukulungisa izinga lokushisa legumbi noma ukususa izingxenye ebhokisini elifaka umswakama elingalungile, kumswakama ofanelekayo- ibhokisi lobufakazi)
II.Ukuphathwa kwenqubo (izindlela zokugcina izingxenye ezizwelayo umswakama)
1. Ukuze uvimbele umonakalo ezingxenyeni ezibangelwa ugesi omile, lapho kubhidlizwa iphakethe levacuum yezingxenye ezizwela umswakama, umqhubi kufanele aqale agqoke amagilavu amahle amile, indandatho yesandla emile, abese evula iphakethe levacuum kudeskithophu evikelwe kahle nge-static. ugesi.Hlola ukuthi izinga lokushisa nomswakama izinguquko zekhadi lezingxenye ziyahlangabezana yini nezidingo, futhi izingxenye ezihlangabezana nezidingo zingalebula.
2. Uma uthola izingxenye eziningi ezizwelayo ukuswakama, yiba ngowokuqala ukuqinisekisa ukuthi izingxenye zifanelekile yini.
3. Hlola ukuthi isikhwama sokuvikela umswakama sidinga ukuhambisana ne-desiccant, ikhadi lokuswakama elihlobene, njll.
4. Izingxenye ezizwela umswakama (IC) ngemva kokuqaqa i-vacuum, zibuyele ku-solder ngaphambi kwesikhathi sokuchayeka emoyeni akumele zidlule izinga lezingxenye ezizwelayo zomswakama, kufanele zihambisane ngokuqinile nezindinganiso ezihambisanayo ze-PCBA processing plant sebenza.
5. ukugcinwa kwezinto ezingavuliwe kufanele kugcinwe ngokwezidingo, ngoba izingxenye ezivuliwe zidinga ukubhakwa futhi zifakwe ezikhwameni ezivikela umswakama kanye ne-vacuum evalwe ngaphambi kokuba zigcinwe.
6. Ngezingxenye ezingafanelekile, zinikeze izisebenzi ezilawula ikhwalithi ukuze zibuyele endaweni yokugcina impahla.
III.Isikhathi sokugcina sezingxenye
Ingakapheli iminyaka emi-2 kusukela ngosuku lokukhiqizwa komkhiqizi wengxenye ngezinjongo zokusungula.
Ngemuva kokuthenga, sonke isikhathi se-inventory yomsebenzisi wefekthri ngokuvamile asidluli unyaka ongu-1: Uma indawo yemvelo iyifekthri yomshini enomswakama uma kuqhathaniswa, ngemva kokuthengwa kwezingxenye ezihlanganiswe phezulu, kufanele zisetshenziswe phakathi nezinyanga ezi-3, futhi ukuswakama okufanele - kufanele kuthathwe. endaweni yokugcina kanye nengxenye yokupakisha ukufakazela izinyathelo.
