Qhov ua tiav PCB txheej txheem electroplating suav nrog kev kho tom qab ntawm electroplating. Hais lus dav dav, txhua qhov kev kho hluav taws xob yog kho tom qab nws tau ua hluav taws xob. Qhov kev kho tom qab yooj yim tshaj plaws yog siv dej kub ntxuav thiab kom qhuav. Thiab ntau txheej txheej kuj tseem xav tau kev tso xim, pleev xim, pleev xim, pleev xim, pleev xim thiab lwm yam tom qab ua tiav, txhawm rau ua kom txheej txheej ua tau zoo dua thiab ua kom muaj zog.

Yuav ua li cas nrog PCB tom qab electroplating

Txoj kev kho tom qab plating tuaj yeem faib ua 12 pawg hauv qab no:

1, ntxuav;

2, qhuav;

3, tshem tawm hydrogen;

4, polishing (tshuab polishing thiab electrochemical polishing);

5, passivation;

6, xim;

7, zas xim;

8, kaw;

9, kev tiv thaiv;

10. tha xim;

11, txheej txheej tsis tsim nyog tshem tawm;

12, da dej rov qab.

Raws li kev siv lossis tsim lub hom phiaj ntawm cov hlau lossis cov khoom siv hlau tsis yog hlau, kev kho tom qab tuaj yeem faib ua peb pawg, uas yog txhawm rau txhim kho lossis txhim kho kev tiv thaiv, ua kom zoo nkauj thiab ua haujlwm tau zoo.

(1) Tiv thaiv kev kho tom qab

Nrog rau qhov tshwj tsis yog chrome plating, tag nrho lwm cov txheej txheej tiv thaiv, thaum siv los ua txheej txheej, yuav tsum tau kho tom qab kom zoo los tswj lossis txhim kho lawv cov khoom tiv thaiv. Feem ntau txoj kev kho tom qab yog passivation. Txhawm rau tiv thaiv qhov xav tau ntau dua rau txheej txheej txheej, piv txwv li, npog lub teeb txheej txheej, los ntawm kev tiv thaiv ib puag ncig thiab kev txiav txim siab tus nqi, tuaj yeem siv dej txheej txheej txheej.

(2) kho tom qab kho

Kev kho kom zoo nkauj tom qab – kev kho mob yog txheej txheem ib txwm muaj hauv cov hlau tsis plating. Piv txwv li, plating ntawm kub kub, ua piv txwv nyiaj, tooj liab qub, txhuam, pleev xim lossis pleev xim thiab lwm yam kev kho kom zoo nkauj. Cov kev kho mob no tseem xav tau qhov saum npoo los npog nrog txheej txheej. Qee lub sij hawm siv cov xim txheej xim xim txawm tias, piv txwv li luam aureate, liab, ntsuab, ntshav tos rau xim txheej.

(3) Kev ua haujlwm tom qab ua tiav

Qee cov khoom siv hlau tsis yog xim hlau tau tsim los rau kev xav tau ntawm kev ua haujlwm, thiab qee qhov kev kho kom haum xeeb yuav tsum tau ua tom qab electroplating. Piv txwv li, raws li txheej txheej txheej ntawm cov hlau nplaum tiv thaiv txheej, raws li txheej txheej txheej txheej txheej ntawm txheej txheej, thiab lwm yam.
