Chithandizo pamaso mkuwa kumira

1. Deburring: Gawo lapansi limadutsa pobowola mkuwa usanamire. Ngakhale ndondomekoyi sachedwa burrs, ndi yofunika kwambiri chobisika ngozi imene imayambitsa metallization wa otsika mabowo. Iyenera kutengera njira yaukadaulo ya deburring kuti ithetse. Kawirikawiri njira zamakina zimagwiritsidwa ntchito popanga dzenje m'mphepete ndi khoma lamkati la dzenje popanda mipiringidzo kapena plugging.
2. Kuchepetsa mafuta
3. Kuchiza mankhwala: makamaka kuonetsetsa kuti mgwirizano wabwino pakati pa zokutira zitsulo ndi gawo lapansi.
4. Chithandizo choyambitsa: makamaka amapanga "malo oyambira" kuti apange yunifolomu yoyika mkuwa.

Zifukwa za voids m'bowo plating:
Khoma lomangira dzenje lopangidwa ndi 1PTH
(1) Zomwe zili mkuwa, sodium hydroxide ndi ndende ya formaldehyde mu sinki yamkuwa
(2) Kutentha kwa bafa
(3) Kuwongolera njira yothetsera
(4) Kutentha kutentha
(5) Kugwiritsa ntchito kutentha, ndende ndi nthawi ya pore modifier
(6) Gwiritsani ntchito kutentha, ndende ndi nthawi yochepetsera
(7) Oscillator ndi swing

2 Hole khoma plating voids chifukwa cha kusamutsa chitsanzo
(1) Chimbale chopangira mankhwala chisanachitike
(2) Guluu wotsalira potuluka
(3) Pretreatment micro-etching

3 Mabowo omata makhoma opangidwa ndi ma plating
(1) Micro-etching of pattern plating
(2) Kuboola (lead tin) sikubalalika bwino

Pali zinthu zambiri zomwe zimapangitsa kuti ma voids akuya, chofala kwambiri ndi PTH coating voids, chomwe chingachepetse bwino kutulutsa kwa PTH voids poyang'anira magawo ofunikira a potion. Komabe, zinthu zina sizinganyalanyazidwe. Pokhapokha poyang'anitsitsa mosamala komanso kumvetsetsa zomwe zimayambitsa kubisala ndi zizindikiro za zolakwika zomwe zingathetsere mavuto panthawi yake komanso mogwira mtima komanso ubwino wa mankhwalawo ukhoza kusungidwa.
