Khetha kwaye ubeke umatshiniyinkqubo ebaluleke kakhulu kwimveliso yombane.
Indibano ye-SMT ibandakanya iinkqubo ezininzi ezinzima, kwaye ukuyakha ngokufanelekileyo kuya kuba ngumngeni omkhulu.Ifektri ye-SMT ngolawulo lwemveliso yenzululwazi inokuphucula imveliso iyonke, kwaye iphucule isantya sayo.Kufuneka unikele ingqalelo phantse kuyo yonke imiba enxulumene nomatshini we-SMT kunye nokuhlanganisa.Kwanawona manqaku mancinci angakhokelela ekusebenzeni okungaqhelekanga kwindibano nakwimveliso.
Isantya sokunyuka kweUmatshini we-SMTkuxhomekeke ngokungangqalanga ukuba inkqubo yokuhlanganisa igudile.Ukuba i-patch ye-SMT yenziwe ngokungafanelekanga kwaye idityanisiwe, ichip mounterunokuba neengxaki.Kukho iindlela ezininzi kunye neenkqubo zokuphucula ukusebenza kakuhle kokwenziwa kwebhodi yesekethe kunye novavanyo lwendibano, okukhokelela kwimveliso egqibeleleyo yokusebenza.Masixoxe ngezi ngongoma zilandelayo:
I. Injongo yotshintsho lwamacandelo ambalwa
Kwibhodi yesiphaluka, uya kubona amacandelo ahlukeneyo kwibhodi enye, edlala indima ebaluleke kakhulu kwinkqubo ye-SMT laminating.Kuba kunye, zisetyenziselwa ukwenza yonke i-PCBA kunye nokufezekisa umsebenzi wombane woqhagamshelwano.
Utshintsho kula macandelo lunokubangela ubunzima kwinkqubo yokuvelisa.Kubalulekile ukuqaphela ukuba iindawo ezahlukeneyo zePCBA zivela kubenzi abahlukeneyo, ziya kwahluka.Asingabo bonke abavelisi abanokuvelisa izinto ezifanayo.Amalungu abo anokwahluka ngobukhulu, imilo kunye nomsebenzi.
Ukuba kukho amacandelo ahlukeneyo, kunzima ukwenza umsebenzi osebenzayo.Kwinkqubo yokucubungula i-patch, ngaphantsi kweentlobo zamacandelo, ngcono, imodeli ye-brand edibeneyo idibeneyo, ingcono, ukuba kukho utshintsho kufuneka lube luphantsi kangangoko kunokwenzeka.
II.Kugxilwe ngakumbi kwindibano yePCBA (imveliso kunye neemfuno)
Ukuba awuzazi iimfuno zebhodi yokukhanya ye-PCB, uceba njani ukuphucula ukusebenza kakuhle kokwenziwa kwe-PCBA?Ngoko ke, kubalulekile ukuqonda kakuhle imeko ye-PCB kwaye usebenze ngokufanelekileyo.Kulapho inkqubo yokuvelisa idlala indima ebalulekileyo.Kufuneka ugxininise ekuqhubeni inkqubo yokuvelisa ngendlela ehlangabezana nazo zonke iimfuno zePCBA.Inkqubo yokwenziwa kwendibano yePCB iya kuqinisekisa ukuba imveliso iyasebenza kwaye ikumgangatho ophezulu.
III.Qonda inyathelo ngalinye lenkqubo ye-SMT
Inyathelo ngalinye kwinkqubo ye-SMT yonyusa ukubaluleka kokwenziwa kwemveliso.Iingxaki ezahlukeneyo zinokuvela ngexesha lamanyathelo kunye nezigaba.Ubunzima bunokuvela kwiinkqubo ezahlukeneyo, ezikhokelela kwiingxaki ezisemgangathweni kunye neempawu ze-thermal.Ngale ndlela, inkqubo yemveliso inokuthatha ixesha elingakumbi, nto leyo ebangela ukulibaziseka kokuhanjiswa kwemveliso.Oku kunokuba yingozi kuba ukuthembeka kwakho kuya kuncitshiswa.
Ukuba uyaliqonda inyathelo ngalinye elithathiweyo kwinkqubo ye-SMT, zonke ezi ngxaki aziyi kuvela.Kuya kukunceda uqonde ukuba ziphi iingxaki kunye nendlela yokuzisombulula.Oku kunokunceda ukwandisa imveliso, kwaye ukuthembeka kwakho kuya kulunga.
