Ukwelashwa ngaphambi kokucwila kwethusi

1. I-Deburring: I-substrate ihamba ngenqubo yokumba ngaphambi kokucwila kwethusi. Nakuba le nqubo ithambekele kuma-burrs, iyingozi ecashile ebaluleke kakhulu ebangela i-metalization yezimbobo eziphansi. Kumele isebenzise indlela yobuchwepheshe yokukhipha imali ukuze ixazulule. Imvamisa izindlela ezisebenza ngomshini zisetshenziswa ukwenza umphetho wembobo nodonga lwembobo yangaphakathi ngaphandle kwama-barbs noma ukuxhuma.
2. Ukwehlisa amafutha
3. Ukwelashwa kwe-roughening: ikakhulukazi ukuqinisekisa amandla amahle okubopha phakathi kwensimbi ne-substrate.
4. Ukwelashwa kokwenza kusebenze: ikakhulukazi kwakha “isikhungo sokuqalwa” ukwenza iyunifomu yokubeka ithusi.

Izimbangela ze-voids embotsheni yodonga lwembobo:
Imbobo yodonga lokumboza imbobo edalwe yi-1PTH
(1) Okuqukethwe kwethusi, i-sodium hydroxide kanye nokugxila kwe-formaldehyde kusinki yethusi
(2) Izinga lokushisa lokugeza
(3) Ukulawulwa kwesixazululo sokwenza kusebenze
(4) Izinga lokushisa lokuhlanza
(5) Izinga lokushisa lokusebenzisa, ukugxila kanye nesikhathi se-pore modifier
(6) Sebenzisa izinga lokushisa, ukugxila kanye nesikhathi sokunciphisa i-ejenti
(7) I-oscillator nokushwiba

2 Izimbobo zokunamathisela odongeni ezibangelwa ukudluliswa kwephethini
(1) Ipuleti lebhulashi lokwelashwa ngaphambi kokwelashwa
(2) Ingcina yeglue ephuma emlonyeni
(3) Pretreatment micro-etching

3 Izimbobo zokunamathisela odongeni ezibangelwa ukucwecwa kwephethini
(1) I-Micro-etching yephethini yokucwenga
(2) I-Tinning (i-lead tin) inokuhlakazeka okubi

Kunezici eziningi ezibangela i-coating voids, okuvame kakhulu i-PTH coating voids, enganciphisa ngempumelelo ukukhiqizwa kwe-PTH coating voids ngokulawula imingcele yenqubo efanele ye-potion. Nokho, ezinye izici azinakuzitshwa. Kuphela ngokubheka ngokucophelela nokuqonda izimbangela zokumboza ama-voids kanye nezici zokukhubazeka lapho izinkinga zingaxazululwa ngesikhathi nangendlela ephumelelayo futhi izinga lemikhiqizo lingagcinwa.
