Ukuhlanganiswa kwe-PCB kuyinqubo yokukhiqiza amabhodi esekethe aphrintiwe, indlela yokukhiqiza eguqula izinto ezingavuthiwe zibe amabhodi omama we-PCB emikhiqizweni kagesi.Ingasetshenziswa ezimbonini eziningi, kuhlanganise nezempi kanye ne-aerospace.Namuhla sizofunda ngolwazi oluhlobene ne-PCB ndawonye.
I-PCB iwucezu oluncane, oluyisicaba lwempahla ye-dielectric enemigudu yokuqondisa efakwe kuyo.Lezi zindlela zixhuma izingxenye ezihlukahlukene ze-elekthronikhi.Zibuye zisetshenziselwe ukuxhuma izingxenye kumasokhethi kumabhodi wesifunda aphrintiwe.Umhlangano we-PCB wuhlelo lokukhiqiza amabhodi wesekethe wemikhiqizo kagesi.Inqubo ibandakanya ukuqopha amaphethini ku-substrate ye-dielectric bese wengeza ama-electronics ku-substrate.
Isinyathelo sokuqala senqubo yokuhlanganisa ye-PCB ephelele ukwakha idizayini ye-PCB.Umklamo wakhiwe kusetshenziswa isofthiwe ye-CAD (Computer Aided Design).Uma umklamo usuqedile, uthunyelwa ohlelweni lwe-CAM.Uhlelo lwe-CAM lusebenzisa idizayini ukuze lukhiqize izindlela zomshini nemiyalo edingekayo ukuze kwenziwe i-PCB.Isinyathelo esilandelayo ukunamathisela iphethini oyifunayo ku-substrate, okuvame ukwenziwa kusetshenziswa inqubo ye-photochemical.Ngemuva kokuqopha iphethini, izingxenye ze-elekthronikhi zifakwa ku-substrate futhi zithengiswe.Ngemuva kokuthi inqubo yokuhlanganisa isiqediwe, i-PCB iyahlanzwa futhi ihlolwe ikhwalithi.Uma isidlulile ekuhlolweni, isilungele ukusetshenziswa.
Uma kuqhathaniswa nezindlela zokuhlanganisa ze-PCB zendabuko, ukucubungula komhlangano wesimanje we-SMT kunezinzuzo eziningi.Enye yezinzuzo ezinkulu ukuthi umhlangano we-SMT uvumela imiklamo eyinkimbinkimbi kunezinye izindlela.Lokhu kungenxa yokuthi umhlangano we-SMT awudingi izimbobo zokumba ukuze uxhume izingxenye ezihlukahlukene.Lokhu kusho ukuthi imiklamo eyinkimbinkimbi ingadalwa ngaphandle kokukhathazeka ngemikhawulo yokumba ngokomzimba.Enye inzuzo yomhlangano we-SMT ukuthi ishesha kakhulu kunezinye izindlela.Zonke izinyathelo ezidingekayo zenziwa emshinini owodwa.Lokhu kusho ukuthi asikho isidingo sokuhambisa i-PCB isuka komunye umshini iye komunye, okonga isikhathi esiningi.
Ukuhlanganiswa kwe-SMT futhi kuyindlela engabizi kakhulu yokukhiqiza ama-PCB emikhiqizo kagesi.Lokhu kungenxa yokuthi ishesha kakhulu kunezinye izindlela, okusho ukuthi kudingeka isikhathi esincane nemali ukuze kukhiqizwe inani elifanayo lemihlangano ye-PCB.Kodwa inobubi obuthile.Enye yezinto ezimbi kakhulu ukuthi kunzima kakhulu ukulungisa imihlangano ye-PCB eyenziwe kusetshenziswa le ndlela.Lokhu kungenxa yokuthi isifunda siyinkimbinkimbi kakhulu kunezinye izindlela.
Okungenhla ulwazi mayelana ne-PCB engifuna ukwabelana nawe.Umhlangano we-SMT njengamanje uyindlela engcono kakhulu yokucubungula yokuhlanganisa i-PCB.Ukuze uthole ulwazi olwengeziwe ngalokhu, sicela usithinte.
