Ukuhlanganisa izindlela ezintsha zekhwalithi nomklamo wokuhlola ongokwesiko ekuhlanganisweni kwegagasi okunganomthofu kunciphisa ukuhlukahluka okungadingekile, kunciphisa ukulahlekelwa kokukhiqiza futhi kulethe izinzuzo ezinkulu.Ukufeza umgomo ngendlela engcono kakhulu, khiqiza yonke imikhiqizo ngangokunokwenzeka ngokuphambuka okuncane phakathi kwemikhiqizo.
Izici ezilawulekayo zenqubo ye-wave soldering engenamthofu:
Ukuze udizayine ukuhlolwa kwenqubo ye-wave soldering enengqondo, qala ngokuklelisa inkinga, umgomo kanye nezici ezilindelekile zokuphumayo nezindlela zokulinganisa.Bese unquma yonke imingcele yenqubo futhi uchaze izici ezifanele ezithinta imiphumela:
1. Izinto ezilawulekayo:
I-C1 = izici ezinomthelela obalulekile ohlelweni futhi zingalawulwa ngokuqondile;
C2 = Isici esidinga ukumisa inqubo uma isici se-C1 sishintsha.
Kule nqubo, kukhethwe izici ezintathu ze-C1:
B = isikhathi sokuxhumana
C = izinga lokushisa ngaphambi kokushisa
D = inani lokuguquguquka
2. Isici somsindo siwukuguquguquka okuthinta ukuchezuka futhi akunakwenzeka noma kuyabiza ukusilawula.Izinguquko kuzinga lokushisa lasendlini, umswakama, uthuli, njll. ngesikhathi sokukhiqiza/ukuhlola.Ngezizathu ezingokoqobo, ingxenye yomsindo ayizange ifakwe ekuhlolweni.Inhloso eyinhloko ukuhlola umnikelo wezinga ngalinye elithonya izici.Ukuhlola okwengeziwe kufanele kwenziwe ukuze kulinganiswe impendulo yabo ekucubunguleni umsindo.
Bese ukhetha izici eziphumayo ezidinga ukulinganiswa: inani lezikhonkwane ngaphandle kwamabhuloho e-solder kanye nokufaneleka kokugcwaliswa.Ngokuvamile isifundo esisodwa ngesikhathi sisetshenziswa ukuze kutholwe amapharamitha alawulekayo, kodwa lokhu kuhlola kusebenzise i-L9 orthogonal array.Ezivivinyweni eziyisishiyagalolunye kuphela, amazinga amathathu ezici ezine aphenywa.
Ukusethwa kokuhlolwa okufanele kuzoveza idatha ethembeke kakhulu.Uhla lwamapharamitha okulawula kufanele lube ngokwedlulele ngendlela engokoqobo ukuze le nkinga ibonakale;kulesi simo, ukungena kabi kwamabhuloho e-solder kanye ne-vias.Ukulinganisa umphumela we-bridging, izikhonkwane ezidayisiwe ngaphandle kwebhuloho zibaliwe.Umthelela wokungena ngembobo, imbobo ngayinye egcwaliswe ngesoda imakwe njengoba kukhonjisiwe.Isibalo esiphezulu samaphuzu ebhodi ngalinye singama-4662.
