1. Ukwelashwa ngaphambiliukucwiliswaithusi 

1). Burring

Inqubo yokubhoboza ye-substrate ngaphambi kokucwila kwethusi kulula ukukhiqiza i-burr, okuyingozi ebaluleke kakhulu efihlekile ku-metalization yemigodi engaphansi.Kumele ixazululwe ngobuchwepheshe bokukhipha imali.Ngokuvamile ngezindlela mechanical, ukuze onqenqemeni imbobo kanye odongeni imbobo yangaphakathi ngaphandle barbed noma imbobo ukuvinjwa mkhuba.

1).Ukwehlisa amafutha

2). Ukucutshungulwa okuqinile:

Iqinisekisa ngokuyinhloko amandla okubopha okuhle phakathi kwe-metal coating kanye ne-matrix.

3)Ukwenza kusebenze ukwelashwa:

"Isikhungo sokuqalwa" esiyinhloko sakhiwe ukwenza i-copper deposition iyunifomu

1. Isizathu somgodi wokumboza imbobo:

1)Imbobo yodonga olumboze imbobo ebangelwa i-PTH

(1) Okuqukethwe kwethusi kwe-copper sink cylinder, i-sodium hydroxide kanye nokugxila kwe-formaldehyde

(2) izinga lokushisa ethangini

(3) Ukulawulwa koketshezi olusebenzayo

(4) Izinga lokushisa lokuhlanza

(5) izinga lokushisa lokusebenzisa, ukugxila kanye nesikhathi se-agent yonke ye-pore

(6) Izinga lokushisa lesevisi, ukugxila kanye nesikhathi sokunciphisa i-ejenti

(7) Ama-oscillator kanye nokushwiba

2)Ukudluliswa kwephethini okubangelwa izimbobo zokumboza imbobo

(1) Ipuleti lebhulashi lokwelashwa

(2) ingcina yeglue ye-orifice

(3) I-Microcorrosion ye-pretreatment

3)Figure Plating okubangelwa imbobo odongeni izimbobo enamathela

(1) I-Graphic electroplating microetching

(2) i-tin plating (i-lead tin) ukuhlakazeka okubi

Kunezici eziningi ezibangela imbobo yokugqoka, okuvame kakhulu imbobo yokugqoka ye-PTH, ngokulawula imingcele yenqubo efanele inganciphisa ngempumelelo ukukhiqizwa kwembobo yokugqoka i-PTH.Kodwa ezinye izici azikwazi ukushaywa indiva, kuphela ngokubhekwa ngokucophelela, ukuqonda imbangela yembobo yokugqoka kanye nezici zokukhubazeka, ukuze kuxazululwe inkinga ngesikhathi nangendlela ephumelelayo, ukugcina izinga lomkhiqizo.
