1. Kurapa pamberikunyudzamhangura 

1). Burring

Iyo yekuchera muitiro we substrate isati yanyura mhangura iri nyore kugadzira burr, iyo inonyanya kukosha yakavanzika njodzi kune metallization yemakomba akaderera. Inofanirwa kugadziriswa nedeburring tekinoroji. Kazhinji nemichina nzira, kuitira kuti gomba kumucheto uye yomukati gomba rusvingo pasina barbed kana gomba ichivharira chiitiko.

1). Degreasing

2). Coarse processing:

Iyo inonyanya kuvimbisa yakanaka yekubatanidza kusimba pakati pesimbi coating uye matrix.

3)Activating treatment:

Iyo huru "initiation centre" inoumbwa kuita iyo copper deposition yunifomu

1. Chikonzero chegomba rekuvhara madziro:

1)Gomba madziro ekuputira mhango yakakonzerwa nePTH

(1) Mhangura yemhangura yemhangura sink cylinder, sodium hydroxide uye formaldehyde concentration

(2) kupisa kwetangi

(3) Kudzora kwe activation fluid

(4) Kuchenesa tembiricha

(5) tembiricha yekushandisa, kutarisisa uye nguva yeiyo yese pore agent

(6) Sevhisi tembiricha, kutarisisa uye nguva yekudzikisa mumiririri

(7) Oscillators uye swing

2)Patani kuchinjisa kunokonzerwa negomba madziro ekuvhara maburi

(1) Pretreatment brush plate

(2) guruu rakasara remuburi

(3) Microcorrosion ye pretreatment

3)Figure plating inokonzerwa negomba wall coating makomba

(1) Graphic electroplating microetching

(2) tin plating (lead tin) kusapararira zvakanaka

Pane zvinhu zvakawanda zvinokonzeresa gomba rekuputira, iro rinonyanya kuzivikanwa ndiro PTH coating gomba, nekudzora akakodzera maitiro paramita anogona kunyatso kudzikisa kugadzirwa kwePTH coating gomba. Asi zvimwe zvinhu hazvigone kuregererwa, chete kuburikidza nekunyatsocherechedza, kuti unzwisise chikonzero chegomba rekuputira uye maitiro ehurema, kuitira kugadzirisa dambudziko panguva uye inobudirira, kuchengetedza kunaka kwechigadzirwa.
