Cov yeeb yaj kiab ntub dej

Cov yeeb yaj kiab ntub dej yog cov khoom siv los tsim cov ntawv luam tawm Circuit Board. Los ntawm kev npog ib txheej ntawm cov nplaum nplaum rau ntawm cov ntawv ci tooj liab thiab nthuav tawm nws mus rau qhov tshwj xeeb UV teeb, cov qauv luam tawm sib txawv tuaj yeem tsim tau. Cov yeeb yaj kiab ntub dej tuaj yeem pab cov engineers tsim cov khoom siv hluav taws xob zoo thiab cov ntawv luam tawm zoo thaum lub sij hawm raug, kev tsim kho, thiab cov txheej txheem etching.

Cov ntaub ntawv tseem ceeb rau cov yeeb yaj kiab ntub dej ntawm cov ntawv luam tawm muaj xws li photosensitive nplaum, steel mesh printing screen, tooj liab ntawv ci, daim txhuam cev, thiab hauv qab phaj. Ua ntej, lo cov ntawv ci tooj liab ua ke nrog lub hauv paus phaj thiab siv cov nplaum photosensitive rau cov ntawv ci tooj liab. Tom qab ntawd, siv lub tshuab luam ntawv hlau luam ntawv los luam cov qauv mus rau cov nplaum nplaum, ua rau nws tawm mus rau lub teeb UV. Thaum lub sij hawm raug tus txheej txheem, cov photosensitive nplaum yuav zoo siab los ntawm lub teeb, uas yuav pab raws li ib tug cais thaum lub sij hawm txoj kev loj hlob thiab etching txheej txheem. Daim txhuam cev strips yog siv los tuav lub xeev kab rov tav ntawm lub rooj tsav xwm luam tawm.

Yam ntxwv

1. Zoo adhesion thiab kev pab them nqi

Cov yeeb yaj kiab ntub dej nws tus kheej yog cov kua nplaum xiav uas ua los ntawm cov khoom siv photosensitive, nrog rau kev sib ntxiv ntawm cov neeg ua haujlwm photosensitive, pigments, fillers, thiab cov kuab tshuaj. Cov pits thiab khawb ntawm lub substrate yog nyob rau hauv kev sib cuag zoo nrog cov ntaub ntub dej, thiab cov ntaub ntawv ntub dej feem ntau yog sib koom ua ke rau lub substrate los ntawm kev ua ntawm cov tshuaj lom neeg, yog li cov ntaub ntawv ntub dej tau zoo heev adhesion nrog tooj liab ntawv ci ntawm substrate. Kev siv tshuaj ntsuam luam ntawv tuaj yeem ua tiav cov kev pabcuam zoo, uas muab cov xwm txheej rau kev ua haujlwm ntawm high-density nplua hlau PCB.

Cov zaj duab xis ntub dej muaj kev sib cuag zoo thiab kev tiv thaiv nrog lub substrate, thiab txais kev sib cuag tsis zoo, uas ua rau txoj kev kho qhov muag luv luv thiab txo lub zog poob ntawm lub teeb thiab qhov tsis zoo los ntawm lub teeb tawg. Qhov no ua rau qhov kev daws teeb meem ntawm cov yeeb yaj kiab ntub dej feem ntau qis dua 25um, txhim kho qhov tseeb ntawm cov duab kos duab, thaum nyob rau hauv qhov tseeb ntau lawm, qhov kev daws teeb meem ntawm cov zaj duab xis qhuav yog qhov nyuaj mus txog 50um.

2. Tus nqi qis

Lub thickness ntawm cov zaj duab xis ntub dej yog tswj tau, feem ntau nyias dua li cov zaj duab xis qhuav, thiab cov nqi ntim kuj qis dua. Hais txog kev hais lus, tus nqi ntawm cov yeeb yaj kiab ntub dej yog me ntsis qis. Kev tsim nyog tus nqi ntawm cov yeeb yaj kiab ntub dej hauv cov txheej txheem tsim cov kab zoo hauv txheej txheej tau zoo heev, txuag 20 feem pua ​​​​ntawm cov nqi khoom piv rau cov yeeb yaj kiab qhuav. Qhov ceev ntawm kev txhim kho ntub dej yuav tsum yog 30 feem pua ​​​​ntau dua, qhov etching ceev kuj tuaj yeem nce 10 feem pua ​​-20 feem pua, thiab qhov ceev ntawm zaj duab xis fading tuaj yeem nce ntxiv, yog li txuag nqi.

3. Tshem tawm cov burrs ntawm cov npoo

Cov npoo ntawm cov yeeb yaj kiab qhuav tuaj yeem ua rau fuzzing thiab cov yeeb yaj kiab tawg, uas tuaj yeem cuam tshuam rau kev tsim nyog ntawm lub rooj tsavxwm thaum lub sijhawm tsim khoom. Cov npoo ntawm cov yeeb yaj kiab ntub dej tsis pom cov yeeb yaj kiab tawg lossis fuzzing.

Kev sib piv ntawm zaj duab xis ntub dej thiab zaj duab xis qhuav

Kev ua haujlwm ntawm cov yeeb yaj kiab qhuav yog qhov yooj yim, tshwj xeeb tshaj yog nrog kev siv cov tshuab tsis siv neeg zaj duab xis nplaum, uas tuaj yeem ua rau ntawm qhov loj. Txawm li cas los xij, tus nqi ntawm cov yeeb yaj kiab qhuav kuj tseem kim, tab sis nws tuaj yeem npog qhov nrog qhov raug siab.

Cov yeeb yaj kiab ntub dej yog pheej yig dua li zaj duab xis qhuav, tab sis nws tsis tuaj yeem siv rau ntawm cov kab tsis siv neeg. Hauv txoj kev xav, nws yog qhov zoo dua los ua cov xov hlau nyias nyias rau zaj duab xis ntub dej, tab sis nws tsis tuaj yeem npog lub qhov. Nws yog ib qho nyuaj rau kev tswj cov roj zaj duab xis nkag mus rau hauv lub qhov, thiab yuav tsum tau teem ib qho chaw thaiv. Hauv txoj kev xav, qhov tseeb ntawm cov yeeb yaj kiab ntub dej yog siab dua li ntawm cov yeeb yaj kiab qhuav. Txawm li cas los xij, vim yog cov zaj duab xis ntub dej, nws yooj yim rau clamp cov yeeb yaj kiab thaum lub sij hawm graphic electroplating, ua rau nws nyuaj rau kev ua kom cov boards siab thiab yuav tsum tau siv cov khoom sib txuas.
