Cov txheej txheem nthuav dav ntawm PCB ntau lawm (1)

Dab tsi yog cov txheej txheem thev naus laus zis ntawm PCB board ua? PCB Circuit Boards yog siv nyob rau hauv yuav luag tag nrho cov khoom siv hluav taws xob, xws li watches thiab headphones mus rau tub rog thiab aerospace. Txawm hais tias lawv tau siv dav, cov neeg feem coob tsis paub yuav ua li cas PCBs raug tsim. Tom ntej no, cia peb nkag siab txog cov txheej txheem tsim khoom PCB thiab cov txheej txheem tsim khoom! Cov txheej txheem hauv qab no yog ua tiav cov txheej txheem tsim khoom ntawm ntau txheej PCB.

Ib qho, Sab hauv txheej; Nws yog tsuas yog siv los ua cov txheej txheej sab hauv ntawm PCB Circuit Board; txheej txheem ntau lawm yog:

1. Txiav board: Txiav lub PCB substrate rau ntau lawm loj.

2. Kev kho mob ua ntej: Ntxuav lub npoo ntawm PCB substrate kom tshem tawm cov kab mob ntawm qhov chaw.

3. Lamination: Muab cov zaj duab xis qhuav rau ntawm qhov chaw ntawm PCB substrate los npaj rau kev hloov cov duab tom ntej.

4. Raug: Siv cov khoom raug los nthuav tawm cov yeeb yaj kiab uas txuas nrog lub teeb ci ultraviolet, yog li hloov cov duab ntawm cov substrate mus rau cov yeeb yaj kiab qhuav.

5.DE: Lub substrate raug tsim, etched, thiab zaj duab xis tshem tawm kom tiav cov khoom ntawm lub puab txheej pawg thawj coj saib.

Ob, Kev tshuaj xyuas sab hauv; feem ntau yog rau kev tshuaj xyuas thiab kev saib xyuas ntawm board circuits

1. AOI: AOI optical scanning tuaj yeem sib piv cov duab ntawm lub rooj tsavxwm PCB nrog cov ntaub ntawv ntawm lub rooj tsavxwm zoo uas tau nkag mus, thiaj li nrhiav tau qhov tsis xws luag xws li qhov khoob thiab kev nyuaj siab ntawm daim duab board.

2.VRS: Cov ntaub ntawv tsis zoo uas pom los ntawm AOI yuav raug xa mus rau VRS, thiab cov neeg ua haujlwm cuam tshuam yuav ua haujlwm tu.

3. Kho cov hlau: Weld cov hlau kub ntawm qhov sib txawv lossis kev nyuaj siab kom tsis txhob muaj hluav taws xob tsis zoo.

Peb, Lamination; Raws li lub npe implies, nws yog nias ntau txheej sab hauv rau hauv ib lub rooj tsavxwm

1. Browning: Browning tuaj yeem ua rau kom muaj qhov adhesion ntawm lub rooj tsavxwm thiab cov resin, nrog rau kev ua kom cov ntub dej ntawm cov tooj liab.

2. Riveting: Txiav PP rau hauv cov nplooj ntawv me me thiab ib txwm loj kom cov txheej txheem sab hauv yog ua ke nrog cov khoom siv PP.

3. Lamination thiab nias, phiaj tua, gong edging, edging.

Plaub, drilling; Raws li cov neeg siv khoom xav tau, siv lub tshuab drilling txhawm rau txhawm rau qhov sib txawv ntawm qhov sib txawv thiab qhov ntau thiab tsawg, yog li los ntawm qhov nruab nrab ntawm cov laug cam tuaj yeem siv rau kev ua haujlwm tom ntej ntawm cov plug-ins, thiab nws kuj tuaj yeem pab lub rooj tsavxwm kom dissipate tshav kub.

Tsib, Thawj tooj liab; tooj liab-plating lub qhov uas tau drilled rau ntawm txheej txheej board, thiaj li hais tias cov kab ntawm txhua txheej ntawm lub rooj tsavxwm yog kev cob cog rua.

1. Deburring kab: tshem tawm cov burr 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 tag nrho cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm, thiab nyob rau tib lub sij hawm tsub kom cov tooj liab thickness.
