Inqubo ye-hot air reflow soldering empeleni iyinqubo yokudlulisa ukushisa.Ngaphambi kokuqala "ukupheka" ibhodi eliqondiwe, izinga lokushisa lendawo ye-ovini yokugeleza kabusha lidinga ukusethwa.
Izinga lokushisa lezoni ye-ovini eligeleza kabusha liyindawo emisiwe lapho isici sokushisa sizoshisisa ukuze sifinyelele leli phuzu lokusetha izinga lokushisa.Lena inqubo yokulawula iluphu evaliwe kusetshenziswa umqondo wesimanje wokulawula we-PID.Idatha yezinga lokushisa lomoya oshisayo eduze kwale nto ethile yokushisa izobuyiselwa kusilawuli, esinquma ukuvula noma ukuvala amandla okushisa.
Kunezici eziningi ezithinta ikhono lebhodi lokufudumala ngokunembile.Izici ezinkulu yilezi:
- Izinga lokushisa lokuqala le-PCB
Ezimweni eziningi, izinga lokushisa lokuqala le-PCB liyafana nezinga lokushisa legumbi.Uma umehluko omkhulu phakathi kwezinga lokushisa le-PCB nezinga lokushisa legumbi likahhavini, ibhodi le-PCB lizothola ukushisa ngokushesha.
- Geza kabusha izinga lokushisa likahhavini
Izinga lokushisa legumbi le-ovini eligelezayo liyizinga lokushisa lomoya oshisayo.Ingase ihlobane nezinga lokushisa lokusetha kuhhavini ngokuqondile;nokho, akufani nenani lephoyinti lokumisa.
- Ukumelana nokushisa kokudluliswa kokushisa
Yonke into inokumelana nokushisa.Izinsimbi zinokumelana nokushisa okuncane kunezinto ezingezona ezensimbi, ngakho-ke inani lezendlalelo ze-PCB nokuqina kwe-cooper kuzothinta ukudluliswa kokushisa.
- I-PCB amandla okushisa
I-PCB capacitance eshisayo inomthelela ekuzinzeni kokushisa kwebhodi eliqondiwe.Kubuye kube ipharamitha eyinhloko ekutholeni ikhwalithi ye-solder.Ugqinsi lwe-PCB kanye namandla okushisa ezingxenye kuzothinta ukudluliswa kokushisa.
Isiphetho sithi:
Izinga lokushisa lokusetha i-oven alifani ncamashi nezinga lokushisa le-PCB.Uma udinga ukuthuthukisa iphrofayela yokugeleza kabusha, udinga ukuhlaziya amapharamitha ebhodi afana nogqinsi lwebhodi, ukujiya kwethusi, nezingxenye futhi ujwayelane nekhono le-oven yakho yokugeleza kabusha.
