Gada
Haɗin gada ɗaya ne daga cikin lahani na gama gari a samar da SMT.Zai haifar da gajeriyar kewayawa tsakanin abubuwan haɗin gwiwa, kuma dole ne a gyara ta lokacin da ta haɗu da haɗin gada.Akwai dalilai da yawa na haɗin gada
1) Matsalolin ingancin solder manna
① Abubuwan da ke cikin ƙarfe a cikin manna na solder yana da girma, musamman ma idan lokacin bugawa ya yi tsayi sosai, yana da sauƙi don ƙara abun ciki na ƙarfe, yana haifar da IC pin bridging;
② The solder manna yana da low danko da overflows zuwa waje na solder kushin bayan preheating;
③ Digon solder manna hasumiya ba shi da kyau, kuma yana malalowa a waje da kushin solder bayan preheating;
Magani: daidaita rabon manna mai siyarwa ko amfani da manna mai inganci mai inganci.
2) Tsarin bugawa
① A maimaita daidaito na bugu inji ne matalauta, kuma jeri ba ko da (karfe jeri ba shi da kyau, PCB alignment ba shi da kyau), wanda ya sa solder manna da za a buga a waje da kushin, musamman m farar QFP kushin;
② Girma da kauri na samfuri taga ba a tsara daidai ba, kuma Sn Pb gami shafi na PCB kushin zane ba uniform, wanda take kaiwa zuwa wuce kima solder manna.
Magani: daidaita firinta kuma inganta murfin kushin PCB.
3) Yana da wani na kowa dalili a samar da solder manna ne cike da kwarara bayan an danna saboda wuce kima matsa lamba.Bugu da kari, idan daidaiton jeri bai isa ba, abubuwan da aka gyara zasu canza kuma filolin IC zasu lalace.
4) The reflow tanderu dumama kudi ne ma sauri, da sauran ƙarfi a solder manna ba shi da lokaci zuwa volatilize.
Magani: daidaita tsayin axis Z na SMT da yawan dumama tanderun da aka sake fitarwa.
Labari da hotuna daga intanet, idan wani cin zarafi pls da farko tuntube mu don sharewa.
