1. Unyango ngaphambiliukuntywiliselwaubhedu 

1). Burrnge

Inkqubo yokugaya i-substrate ngaphambi kokucwiliswa kobhedu kulula ukuvelisa i-burr, eyona ngozi ibalulekileyo efihliweyo kwi-metalization yemingxuma engaphantsi.Kufuneka isombululwe ngetekhnoloji yokuhlawula imali.Ngokuqhelekileyo ngeendlela zoomatshini, ukwenzela ukuba umda womngxuma kunye nodonga lwangaphakathi lomngxuma ngaphandle kwe-barbed okanye i-hole blocking phenomenon.

1).Ukunciphisa amafutha

2). Ukusetyenzwa okurhabaxa:

Iqinisekisa ubukhulu becala amandla okudibanisa okuhle phakathi kokutyabeka kwesinyithi kunye ne-matrix.

3)Ukuvuselela unyango:

"Iziko lokuqalisa" liqulunqwe ukwenza i-copper deposition uniform

1. Unobangela womngxuma wokugquma eludongeni:

1)Umngxuma wokugquma eludongeni obangelwa yiPTH

(1) Umxholo wobhedu we-cylinder ye-copper, i-sodium hydroxide kunye ne-concentration ye-formaldehyde

(2) ubushushu betanki

(3) Ukulawulwa kolwelo olusebenzayo

(4) Ukucoca ubushushu

(5) ubushushu bokusetyenziswa, ugxininiso kunye nexesha le-agent ye-pore yonke

(6) Ubushushu benkonzo, ugxininiso kunye nexesha le-arhente yokunciphisa

(7) Ii-oscillators kunye ne-swing

2)Ukudluliselwa kwepateni okubangelwa yimingxunya yokwaleka eludongeni

(1) Ipleyiti yebrashi yokulungisa kwangaphambili

(2) iglu eshiyekileyo ye-orifice

(3) I-Microcorrosion ye-pretreatment

3)Figure plating okubangelwa imingxuma eludongeni ukutyabeka imingxuma

(1) Umzobo we-electroplating microetching

(2) ukufakwa kwenkcenkce (itoti yelothe) ukusasazwa kakubi

Kukho izinto ezininzi ezibangela umngxuma wokugquma, eyona nto ixhaphake kakhulu ngumgodi wokugquma we-PTH, ngokulawula iiparitha zenkqubo efanelekileyo inokunciphisa ngokufanelekileyo ukuveliswa komngxuma wokugquma we-PTH.Kodwa ezinye izinto azikwazi ukuhoywa, kuphela ngokuqwalasela ngokucophelela, ukuqonda isizathu somngxuma wokugquma kunye neempawu zeziphene, ukwenzela ukusombulula ingxaki ngexesha elifanelekileyo nangendlela efanelekileyo, ugcine umgangatho wemveliso.
