Plaub.Drilling: Raws li cov neeg siv khoom xav tau, siv lub tshuab drilling los laum qhov sib txawv ntawm qhov sib txawv thiab qhov ntau thiab tsawg ntawm lub rooj tsavxwm, kom lub qhov nruab nrab ntawm cov laug cam tuaj yeem siv rau kev ua haujlwm tom ntej ntawm plug-ins, thiab nws kuj tuaj yeem pab lub rooj tsavxwm kom dissipate. cua sov;
Thib tsib, thawj tooj liab;tooj liab plating rau qhov drilled qhov ntawm txheej txheej board, kom cov kab ntawm txhua txheej ntawm lub rooj tsavxwm yog ua;
1. Deburring kab: tshem tawm cov burrs ntawm ntug ntawm lub rooj tsavxwm lub qhov kom tiv thaiv tsis zoo tooj liab plating;
2. Cov kab tshem tawm cov kua nplaum: tshem tawm cov kua nplaum uas nyob hauv lub qhov;txhawm rau ua kom cov adhesion thaum lub sij hawm micro-etching;
3. Ib qho tooj liab (pth): tooj liab plating nyob rau hauv lub qhov ua rau lub Circuit Court ntawm txhua txheej ntawm lub rooj tsavxwm conduction, thiab tib lub sij hawm ua kom cov tooj liab thickness;
Rau, txheej txheej;txheej txheej txheej yog roughly tib yam li cov txheej txheem txheej txheem ntawm thawj kauj ruam, thiab nws lub hom phiaj yog los pab txhawb txoj kev ua raws li cov txheej txheem ua kom lub voj voog;
1. Kev kho mob ua ntej: ntxuav lub ntsej muag ntawm lub rooj tsavxwm los ntawm pickling, txhuam thiab ziab kom ua kom cov adhesion ntawm cov zaj duab xis qhuav;
2. Laminating zaj duab xis: muab cov zaj duab xis qhuav rau saum npoo ntawm PCB substrate los npaj rau kev hloov cov duab tom ntej;
3. Tawm: irradiate nrog UV teeb kom cov zaj duab xis qhuav ntawm lub rooj tsavxwm tsim ib lub xeev polymerized thiab unpolymerized;
4. Kev tsim kho: yaj cov yeeb yaj kiab qhuav uas tsis tau polymerized thaum lub sij hawm raug, tawm hauv qhov sib txawv;
Xya, theem nrab tooj liab thiab etching;thib ob tooj liab plating, etching;
1. Thib ob tooj liab: Electroplating qauv, hla chemical tooj liab rau qhov chaw tsis npog nrog zaj duab xis qhuav hauv lub qhov;Nyob rau tib lub sijhawm, ntxiv cov conductivity thiab tooj liab thickness, thiab tom qab ntawd mus rau tin plating los tiv thaiv kev ncaj ncees ntawm Circuit Court thiab qhov thaum lub sij hawm etching;
2. SES: Etch hauv qab tooj liab nyob rau hauv qhov chaw txuas ntawm txheej txheej txheej qhuav (dawb zaj duab xis) los ntawm cov txheej txheem xws li tshem tawm zaj duab xis, etching, thiab tin stripping, thiab txheej txheej txheej tam sim no tiav;
