Ukudibanisa iindlela ezintsha zomgangatho kunye noyilo lwemveli-zamalingo kwi-lead-free-wave soldering kunciphisa ukuguquguquka okungeyomfuneko, kunciphisa ilahleko yemveliso kwaye kunikeze izibonelelo ezinkulu.Ukufezekisa injongo ngeyona ndlela ingcono, velisa zonke iimveliso ngokusemandleni ngokutenxa ubuncinci phakathi kweemveliso.
Izinto ezilawulekayo zenkqubo yokuthengisela amaza angalothe:
Ukuze uyile uvavanyo olufanelekileyo lwenkqubo yokuthengisa amaza, dwelisa kuqala ingxaki, injongo kunye neempawu ezilindelekileyo zemveliso kunye neendlela zokulinganisa.Emva koko misela zonke iiparameters zenkqubo kwaye uchaze izinto ezifanelekileyo ezichaphazela iziphumo:
1. Izinto ezinokulawuleka:
C1 = izinto ezinempembelelo ebalulekileyo kwinkqubo kwaye zinokulawulwa ngokuthe ngqo;
C2 = Into efuna ukumisa inkqubo ukuba i-C1 factor iyatshintsha.
Kule nkqubo, izinto ezintathu ze-C1 ziye zakhethwa:
B = ixesha loqhagamshelwano
C = ukushisa kwangaphambili
D = ubungakanani bokuguquguquka
2. Into yengxolo yinto eguquguqukayo echaphazela ukutenxa kwaye ayinakwenzeka okanye ingabizi kakhulu ukuyilawula.Utshintsho kwiqondo lokushisa langaphakathi, ukufuma, uthuli, njl njl ngexesha lokuvelisa / uvavanyo.Ngezizathu eziphathekayo, icandelo lengxolo alizange lifakwe kuvavanyo.Eyona njongo iphambili kukuvavanya igalelo lemiba echaphazela umgangatho ngamnye.Imifuniselo eyongezelelweyo kufuneka yenziwe ukulinganisa impendulo yabo kwinkqubo yengxolo.
Emva koko khetha iimpawu zemveliso ezifuna ukulinganiswa: inani lezikhonkwane ngaphandle kweebhuloho ze-solder kunye nokufaneleka kokuzaliswa.Ngokwesiqhelo into enye ngexesha izifundo zisetyenziselwa ukumisela iiparamitha ezilawulekayo, kodwa olu vavanyo lusebenzise uluhlu lwe-L9 orthogonal.Kwiinkqubo zolingo ezisithoba kuphela, amanqanaba amathathu eemeko ezine zaphandwa.
Ukuseta uvavanyo olufanelekileyo luya kunika eyona datha ithembekileyo.Uluhlu lweeparamitha zolawulo kufuneka lugqithise kangangoko ukwenza ingxaki ibonakale;kule meko, ukungena kakubi kweebhulorho ze-solder kunye ne-vias.Ukulinganisa umphumo we-bridging, izikhonkwane ezithengiswayo ngaphandle kwebhuloho zibalwe.Impembelelo ekungeneni komngxuma, umngxuma ngamnye ozaliswe yi-solder ephawulwe njengoko kubonisiwe.Elona nani lilonke lamanqaku kwibhodi nganye ngama-4662.
