PCB Circuit Board board solder mask txheej txheem yog ib qho ntawm cov kev sib txuas tseem ceeb hauv cov txheej txheem tsim khoom PCB, thiab nws cov teeb meem zoo muaj feem cuam tshuam rau kev ua tau zoo thiab kev ntseeg siab ntawm PCB.Nyob rau hauv cov txheej txheem ntawm daim npog ntsej muag, cov teeb meem zoo ib yam muaj xws li qhov hws, qhov muag tsis tseeb, thiab xau.Cov teeb meem no yuav tsis yog tsuas yog ua rau txo qis PCB kev ua tau zoo thiab kev ntseeg tau, tab sis kuj tseem tuaj yeem ua rau tsis tsim nyog rau kev tsim khoom.Kab lus no yuav qhia txog cov tswv yim los daws cov teeb meem no thiab tshawb nrhiav daim ntawv thov ntawm PCB solder mask screen printing machines hauv kev daws cov teeb meem no.
1. Kev piav qhia txog cov teeb meem zoo hauv PCB solder mask txheej txheem
1. Stomata
Porosity yog ib qho teeb meem zoo hauv cov txheej txheem PCB solder mask.Nws feem ntau yog tshwm sim los ntawm qhov tsis txaus ntawm cov pa hauv cov khoom siv lub npog ntsej muag.Cov pores no yuav ua rau muaj teeb meem xws li kev ua haujlwm tsis zoo ntawm cov hluav taws xob tsis zoo thiab cov hluav taws xob luv luv hauv PCB thaum ua thiab siv tom qab.
2. Virtual soldering
Vuam yog hais txog kev sib cuag tsis zoo ntawm PCB pads thiab cov khoom siv, ua rau tsis muaj zog hluav taws xob ua haujlwm thiab yooj yim luv luv lossis qhib Circuit Court.Virtual soldering feem ntau yog tshwm sim los ntawm tsis txaus adhesion ntawm cov khoom siv lub npog ntsej muag thiab cov ntaub qhwv los yog cov txheej txheem tsis raug.
3. Cov dej ntws tawm
Leakage yog thaum muaj qhov sib txawv ntawm cov hluav taws xob sib txawv ntawm PCB lossis nruab nrab ntawm Circuit Court thiab ib feem hauv av.Kev xau yuav tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm lub voj voog, tab sis kuj yuav ua rau muaj teeb meem kev nyab xeeb.Yog vim li cas rau kev xau tuaj yeem suav nrog cov teeb meem zoo nrog cov ntaub ntawv npog ntsej muag, cov txheej txheem tsis raug, thiab lwm yam.
2. Kev daws teeb meem
Txhawm rau daws cov teeb meem zoo saum toj no, cov kev daws teeb meem hauv qab no tuaj yeem ua:
Rau qhov teeb meem ntawm qhov pores, txheej txheej txheej ntawm cov khoom siv solder tuaj yeem ua kom zoo kom ntseeg tau tias cov khoom nkag mus rau ntawm cov kab, thiab cov txheej txheem ua ntej ci tuaj yeem muab ntxiv kom tso tawm cov roj hauv cov khoom siv los tiv thaiv.Tsis tas li ntawd, koj tuaj yeem ntxiv qhov kev hloov siab ntawm scraper tom qab kev tshuaj ntsuam luam ntawv los pab tshem tawm qhov pores.Ntawm no peb xav kom koj kawm txog cov ntse ntse tsis siv neeg lub ntsej muag lub ntsej muag lub qhov ntsaws lub tshuab nrog nws tus kheej lub zog.Nrog 6 ~ 8 kg ntawm cov roj, nws tuaj yeem ua tiav Lub scraper tuaj yeem sau lub qhov nrog ib qho mob stroke thiab tag nrho cov pa tawm.Tsis tas yuav rov ua dua lub qhov ntsaws ntau zaus.Nws ua haujlwm zoo, txuag lub sijhawm thiab teeb meem, thiab txo qhov seem seem.
Rau qhov teeb meem ntawm virtual soldering, cov txheej txheem tuaj yeem ua kom zoo kom muaj kev sib haum xeeb txaus ntawm cov khoom siv lub npog ntsej muag thiab lub ncoo.Nyob rau tib lub sij hawm, nyob rau hauv cov nqe lus ntawm cov txheej txheem tsis, lub ci kub thiab siab yuav tsum tsim nyog nce los txhim kho lub adhesion ntawm solder resist cov khoom thiab lub ncoo.
Rau cov teeb meem xau, kev tswj xyuas zoo ntawm cov khoom siv hluav taws xob tuaj yeem ua kom muaj zog kom ruaj khov hluav taws xob ua haujlwm.Nyob rau tib lub sij hawm, nyob rau hauv cov nqe lus ntawm cov txheej txheem tsis, lub ci kub thiab lub sij hawm yuav tsim nyog nce mus rau tag nrho solidify lub solder resist cov khoom, yog li txhim kho cov rwb thaiv tsev kev ua tau zoo ntawm lub Circuit Court.
3. Daim ntawv thov ntawm Xinjinhui PCB Circuit Court board solder daim npog qhov ncauj tshuab luam ntawv
Hauv kev teb rau cov teeb meem zoo saum toj no, Xinjinhui PCB solder mask tuaj yeem muab cov kev daws teeb meem zoo.Cov cuab yeej siv thev naus laus zis thev naus laus zis thev naus laus zis thev naus laus zis, uas tuaj yeem tswj hwm tus nqi txheej thiab txoj haujlwm ntawm cov khoom siv npog ntsej muag, kom tsis txhob muaj qhov tshwm sim ntawm qhov hws thiab cov khoom cuav.Nyob rau tib lub sijhawm, cov cuab yeej tseem muaj cov txheej txheem ntse tswj kev ua haujlwm, uas tuaj yeem hloov cov ntaub ntawv xov tooj sai sai hauv 3 mus rau 5 feeb yam tsis tas yuav tsum tau hloov lub log thiab sib koom ua ke cov kev sib txuas ua ke kom paub meej tias lub ntsej muag lub ntsej muag luam ntawv yog qhov tseeb thiab ua haujlwm tau zoo. .
Kev xyaum tau ua pov thawj tias kev siv Xinjinhui PCB circuit board solder mask screen printing tshuab tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov txheej txheem PCB solder mask.Daim ntawv thov ntawm cov cuab yeej no tuaj yeem tsis tsuas yog txo cov khoom lag luam thiab txhim kho kev tsim khoom, tab sis kuj muab cov neeg siv khoom zoo PCB cov khoom kom tau raws li ntau yam kev xav tau.
