1. Cov yam ntxwv ntawm PCB number case
1. Viscosity thiab thixotropy
nyob rau hauv cov txheej txheem ntawm kev luam ntawv Circuit Court boards, screen printing yog ib qho tseem ceeb thiab tseem ceeb txheej txheem. Txhawm rau kom tau txais kev ncaj ncees ntawm cov duab luam tawm, tus number case yuav tsum muaj viscosity zoo thiab tsim nyog thixotropy.
2. Ntsig
cov pigments thiab mineral fillers ntawm PCB inks feem ntau yog khoom. Tom qab kev sib tsoo zoo, lawv qhov loj me tsis pub tshaj 4/5 microns, thiab tsim ib homogeneous ntws hauv cov ntaub ntawv.

2, Hom PCB inks
PCB inks feem ntau muab faib ua peb hom: circuit, solder mask thiab cim inks.
1. Cov cwj mem hauv Circuit Court yog siv los ua txheej txheej thaiv kev tiv thaiv corrosion ntawm Circuit Court. Nws tiv thaiv Circuit Court thaum etching. Nws yog feem ntau ua kua photosensitive; Muaj acid corrosion kuj thiab alkali corrosion kuj.
2. Lub solder resist number case yog siv rau hauv Circuit Court tom qab lub Circuit Court ua tiav los tiv thaiv Circuit Court. Muaj cov kua photosensitive, tshav kub kho thiab UV hardening hom. Cov ntaub ntawv sib txuas tau tshwj tseg rau ntawm lub rooj tsavxwm kom yooj yim vuam ntawm cov khoom siv thiab ua lub luag haujlwm ntawm rwb thaiv tsev thiab tiv thaiv oxidation.
3. Tus cwj pwm tus cwj pwm yog siv los kos rau saum npoo ntawm lub rooj tsavxwm. Piv txwv li, nws feem ntau yog dawb.
Tsis tas li ntawd, muaj lwm yam inks, xws li strippable adhesive number case, silver paste number case, thiab lwm yam.

Daim ntawv thov ntawm PCB yog paub rau txhua tus. Nws tuaj yeem pom hauv yuav luag txhua yam khoom siv hluav taws xob. Muaj ntau hom PCB hauv khw. Cov tuam ntxhab sib txawv tsim tib hom PCB, uas kuj txawv. Nws yog qhov nyuaj rau cov neeg siv kom paub qhov txawv qhov zoo thaum yuav khoom. Hauv qhov no, tus kws tshaj lij tau teeb tsa thiab qhia txog txoj hauv kev kom paub qhov zoo ntawm PCB Circuit Board:

First, Judging los ntawm qhov tsos:
1. Weld tsos.
Vim muaj cov PCB ntau, yog tias qhov vuam tsis zoo, cov khoom PCB yooj yim poob, uas cuam tshuam rau cov vuam zoo thiab cov tsos ntawm PCB. Nws yog ib qho tseem ceeb heev los txheeb xyuas kom zoo thiab ua kom lub interface muaj zog.
2. Cov qauv kev cai rau qhov loj thiab tuab.
Vim tias cov tuab ntawm cov qauv PCB txawv ntawm PCB, cov neeg siv tuaj yeem ntsuas thiab xyuas raws li cov tuab thiab cov lus qhia ntawm lawv tus kheej cov khoom.
3. Lub teeb thiab xim.
Feem ntau, lub rooj tsav xwm sab nraud yog npog nrog tus cwj mem, uas tuaj yeem ua lub luag haujlwm insulating. Yog tias cov xim ntawm lub rooj tsavxwm tsis ci, cov number case tsawg qhia tias cov rwb thaiv tsev nws tus kheej tsis zoo.

Thib ob, Kev txiav txim los ntawm lub phaj:
1. Ordinary HB paperboard thiab 22F yog pheej yig thiab yooj yim rau deform thiab tawg. Lawv tsuas siv tau los ua ib lub vaj huam sib luag xwb. Cov xim ntawm cov khoom saum npoo yog xim daj tsaus nrog cov ntxhiab tsw ntxhiab. Cov txheej tooj liab yog ntxhib thiab nyias.
2. Tus nqi ntawm ib leeg-sided 94v0 thiab CEM-1 boards yog tus nqi siab dua li ntawm daim ntawv. Cov xim ntawm cov khoom nto yog lub teeb daj. Nws yog tsuas yog siv rau kev lag luam boards thiab lub hwj chim boards nrog cov kev ntsuas hluav taws kub.
3. Fiberglass board, nrog tus nqi siab, lub zog zoo thiab ntsuab ntawm ob sab, yog siv rau feem ntau ntawm ob sab thiab ntau txheej nyuaj boards. Copper txheej tuaj yeem ua tau zoo heev thiab zoo, tab sis chav tsev board kuj hnyav heev.
Tsis muaj teeb meem dab tsi xim ntawm tus number case luam tawm ntawm lub Daim Ntawv Luam Tawm Circuit Board, nws yuav tsum du thiab tiaj tus. Yuav tsum tsis txhob muaj cov kab tsis tseeb nthuav tawm tooj liab, blistering, yooj yim ntog tawm thiab lwm yam tshwm sim. Cov cim yuav tsum tau meej, thiab cov roj ntawm lub qhov npog yuav tsum tsis txhob muaj qhov ntse.
