Kurapa mhangura isati yanyura

1. Deburring: Iyo substrate inopinda nenzira yekuchera mhangura isati yanyura. Kunyangwe maitiro aya achiwanzoita maburrs, ndiyo inonyanya kukosha yakavanzika njodzi inokonzera metallization yemakomba akaderera. Inofanirwa kutora deburring tekinoroji nzira yekugadzirisa. Kazhinji mechanical nzira dzinoshandiswa kugadzira mupendero wegomba uye mukati mukati megomba madziro pasina barbs kana plugging.
2. Kubvisa mafuta
3. Roughening kurapwa: kunyanya kuve nechokwadi chekubatana kwesimba pakati pesimbi yesimbi uye substrate.
4. Activation kurapwa: kunyanya inoumba "initiation centre" kuita mhangura deposition yunifomu.

Zvinokonzera voids mugomba madziro plating:
Gomba madziro ekuisa mhango yakakonzerwa ne1PTH
(1) Mhangura yemukati, sodium hydroxide uye formaldehyde kusungwa mumhangura sink
(2) Kupisa kwekugeza
(3) Kudzora kwekugadzirisa mhinduro
(4) Kuchenesa tembiricha
(5) Iyo tembiricha yekushandisa, kutarisisa uye nguva yepore modifier
(6) Shandisa tembiricha, kutarisisa uye nguva yekudzikisa mumiririri
(7) Oscillator uye swing

2 Hole wall plating voids inokonzerwa nekufambisa pateni
(1) Pre-kurapwa brashi ndiro
(2) Nama yakasara pamuromo
(3) Pretreatment micro-etching

3 Hole wall plating voids inokonzerwa nepateni plating
(1) Micro-etching ye pattern plating
(2) Tinning (lead tin) haina kuparadzirwa zvakanaka

Pane zvinhu zvakawanda zvinokonzeresa kuvharisa voids, iyo inonyanya kuzivikanwa ndeye PTH yekuputira voids, iyo inogona kunyatso kudzikisa chizvarwa chePTH coating voids nekudzora akakodzera maitiro paramita yepotion. Zvisinei, zvimwe zvinhu hazvigoni kufuratirwa. Kuburikidza nekunyatsotarisisa uye nekunzwisisa zvikonzero zvekuputira voids uye maitiro ekuremara anogona kugadzirisa matambudziko panguva uye inoshanda uye mhando yezvigadzirwa inogona kuchengetedzwa.
