Cov kev cai sealing rau Printed Circuit Boards (PCBs) feem ntau yog tig los tiv thaiv kev ya raws, oxidation, paug, thiab kev puas tsuaj rau lub cev. Lub hom phiaj yog los xyuas kom meej tias cov laug cam tswj lawv cov hluav taws xob kev ua tau zoo thiab kev ua haujlwm zoo nyob rau hauv cov theem ntawm kev khaws cia, kev thauj mus los, thiab kev ua haujlwm.
Rau tag nrho cov PCBs, nws yog qhov tsim nyog heev - thiab qhov tseem ceeb yog qhov tseem ceeb ntawm Circuit Court densities txuas ntxiv mus ntxiv - tias cov qauv hauv Circuit Court yuav tsum tau encapsulated tag nrho los ntawm lub npog ntsej muag. Cov txheej txheem kev lag luam tau txiav txim siab tias lub npog ntsej muag tuab ntawm txhua qhov chaw ntawm cov khoom siv hluav taws xob ntawm PCB yuav tsum ua kom tau raws li qhov yuav tsum tau muaj tsawg kawg yog 25 μm. Tsis tas li ntawd, qhov℃ntawm encapsulation ua tiav ntawm lub rooj tsavxwm ncaj qha txiav txim siab nws cov hluav taws xob rwb thaiv tsev ntsuas nrog rau nws cov tsis kam mus rau ib puag ncig degradation.
Nyob rau hauv cov ntaub ntawv ntawm cov tshuaj ntsuam - luam inks, qhov zoo ntawm encapsulation yog ncaj qha cuam tshuam los ntawm tej yam xws li kev xaiv ntawm lub vijtsam mesh, number case viscosity, thiab luam ntawv kub thiab ceev; Tsis tas li ntawd, kev hloov pauv hauv qhov siab ntawm cov kab hluav taws xob conductive yuav ua rau muaj qhov sib txawv ntawm qhov ntsuas ntawm encapsulation. Thaum lub qhov ncauj qhov ntswg ua kua tuaj yeem pom tau hais tawm, kev taw qhia ridges hauv lawv cov txheej txheem txheej txheem, ua ntej- ua cov yeeb yaj kiab qhuav muaj qhov zoo sib xws: muab qhov siab ntawm cov kab hluav taws xob ntawm lub rooj tsavxwm tsis pub tshaj qhov tuab ntawm cov yeeb yaj kiab qhuav nws tus kheej, qhov tshwm sim ntawm cov ntaub ntawv yuav zoo ib yam thiab zoo ib yam thoob plaws tag nrho ntawm lub rooj tsavxwm. Yog li ntawd, kev siv cov yeeb yaj kiab qhuav ua rau qhov kev ua tiav ntawm qhov tsawg kawg nkaus ntawm cov txheej txheem encapsulation ntawm 25 μm thoob plaws tag nrho saum npoo ntawm lub rooj tsav xwm luam tawm.
