Dab tsi yog cov txheej txheem tsim khoom ntawm ib nrab-qhov PCB board

Hlau ib nrab qhov (slot) txhais tau hais tias ib lub qhov laum yog holed thiab tom qab ntawd qhov thib ob xyaum thiab cov txheej txheem yog ua, thiab thaum kawg ib nrab ntawm lub metallized qhov (slot) yog khaws cia, uas yog, lub metallized qhov ntawm ntug ntawm lub phaj yog. txiav hauv ib nrab. Nws tseem hu ua stamp qhov hauv kev lag luam PCB. Nws muaj peev xwm mus ncaj nraim rau lub qhov ntug mus rau lub ntsiab ntug kom txuag tau connectors thiab qhov chaw. Nws feem ntau tshwm nyob rau hauv cov teeb liab circuits. Yog li, dab tsi yog cov txheej txheem ntawm ib nrab-qhov PCB board?

Cov txheej txheem tsim khoom ntawm ib nrab-qhov PCB board suav nrog cov kauj ruam hauv qab no:

1. Kev tsim hluav taws xob sab nrauv;

2. Cov qauv substrate yog electroplated nrog tooj liab;

3. Cov qauv substrate yog electroplated nrog tin;

4. Ib nrab qhov kev kho mob;

5. Tshem tawm cov yeeb yaj kiab;

6. Etching.

Txheej txheem txhais:

(1) Yuav ua li cas tswj cov khoom zoo tom qab tsim lub semi-metallized qhov ntawm ntug ntawm lub rooj tsavxwm, xws li tooj liab pos rau ntawm lub qhov phab ntsa, qhov seem, thiab lwm yam, yeej ib txwm muaj teeb meem nyuaj nyob rau hauv cov txheej txheem ua.

(2) Rau hom PCB no nrog rau tag nrho cov kab ntawm semi-metallized qhov nyob rau sab ntawm lub rooj tsavxwm, nws yog yus muaj los ntawm ib tug kuj me me qhov taub, uas yog feem ntau yog siv rau cov ntxhais board ntawm lub motherboard, thiab yog welded nrog ib tug me me qhov. lub motherboard thiab cov pins ntawm cov khoom los ntawm cov qhov no. Yog hais tias muaj tooj liab pos nyob rau hauv cov semi-metallized qhov, thaum lub chaw tsim tshuaj paus yog soldering, nws yuav ua rau tsis muaj zog solder taw, virtual soldering, thiab loj choj luv luv Circuit Court ntawm ob pins.

Cov saum toj no yog cov txheej txheem ntau lawm ntawm ib nrab-qhov PCB board.
