Yam cuam tshuam rau tus number case thickness ntawm pcb

Printed circuit board number case yog cov txheej txheem siv ntau hauv kev lag luam hluav taws xob, uas tuaj yeem tsim cov txheej txheem rwb thaiv tsev ntawm cov ntawv luam tawm los tiv thaiv nws los ntawm kev cuam tshuam sab nraud. Txawm li cas los xij, lub thickness ntawm cov ntawv luam tawm Circuit Board number case yog ib qho tseem ceeb heev.

Ua ntej, ib qho ntawm qhov cuam tshuam rau tus number case thickness ntawm cov laug cam yog viscosity ntawm tus number case. Qhov siab dua qhov viscosity, qhov tsis zoo ntawm cov kua dej ntawm tus number case, ua rau cov xim number case tuab dua. Thaum lub viscosity ntawm tus number case yog siab dhau lawm, nws yog ib qho yooj yim rau kev khiav grooves thiab blocks, uas cuam tshuam rau conductivity thiab zoo nkauj ntawm lub rooj tsavxwm Circuit Court. Yog li ntawd, lub viscosity ntawm tus number case yuav tsum tau kho kom haum raws li qhov sib txawv daim ntawv thov scenarios.

Qhov thib ob, qhov roughness ntawm cov ntawv luam tawm Circuit Board nto kuj cuam tshuam rau lub thickness ntawm tus number case. Yog hais tias qhov saum npoo ntawm lub rooj tsavxwm yog du dhau lawm, nws yog ib qho nyuaj rau tus number case kom ua raws li qhov saum npoo los ua ib zaj duab xis nyias, uas tuaj yeem ua rau cov txheej tuab tsis txaus thiab cuam tshuam rau kev ntseeg tau ntawm Circuit Court. Yog tias qhov chaw ntxhib dhau lawm, nws tuaj yeem ua rau cov pas dej pleev xim rau daim ntawv, cuam tshuam rau kev zoo nkauj thiab kev ntseeg siab ntawm lub rooj tsavxwm. Hauv kev tshuaj ntsuam luam ntawv, qhov ruaj khov dua qhov viscosity ntawm tus number case ntawm lub phaj luam ntawv, qhov zoo dua. Tab sis tom qab hloov mus rau lub substrate, viscosity nce sai li sai tau.

Tsis tas li ntawd, lub diluent ntawm tus number case kuj tuaj yeem cuam tshuam rau lub thickness ntawm tus number case txheej. Feem ntau diluents muaj xws li ntau yam organic solvents thiab dej. Thaum lub diluent concentration tsawg dhau lawm, tus number case sib xws nce thiab cov txheej thickness kuj nce. Yog hais tias qhov concentration ntawm cov diluent siab dhau lawm, nws tuaj yeem ua rau cov kua dej tsis zoo, cuam tshuam rau qhov sib xws thiab thickness ntawm txheej.

Hauv kev tshuaj ntsuam luam ntawv, kev tshuaj ntsuam luam ntawv kuj yog ib qho tseem ceeb cuam tshuam rau tus number case thickness. Lub luag haujlwm ntawm qhov screen yog tswj tus cwj mem thiab txhawb nqa tus qauv. Tus lej ntawm tus lej nkag yuav tsum sib npaug rau tus lej ntawm tus lej uas tau pauv mus rau lub substrate los ntawm kev sau txhua lub mesh nrog tus cwj mem thiab ua kom tiav txhua lub mesh kom ntau li ntau tau thaum luam ntawv.

Muaj ntau yam kev khiav hauj lwm uas cuam tshuam rau lub thickness ntawm tus number case, xws li hardness ntawm lub scraper, lub cross-section duab, luam ntawv ceev, luam ntawv siab, net nrug, lub scraping lub kaum sab xis, thiab lwm yam.

Tus number case scraper yog ua los ntawm cov roj hmab elastic. Thaum luam ntawv, lub hauv ntej kawg ntawm lub scraper hu rau lub npov phaj thiab tsim ib lub kaum sab xis nrog nws tib lub sij hawm, siv lub siab thiab txav, kom tus number case nyob rau hauv lub screen thav duab leaks los ntawm lub mesh thiab xa mus rau lub substrate.

Rau cov duab sib txuas ntawm lub scraper, lub sharper ntawm ntug ntawm lub scraper, lub finer tus kab kev sib cuag, qhov me me tus number case tso zis; Lub rounder ntawm ntug, ntau tus number case yuav raug tsim. Yog li ntawd, nyob rau hauv kev luam ntawv, tus ntoo khaub lig-section duab ntawm lub scraper yuav tsum raug xaiv kom raug.

Kub thiab av noo kuj muaj qee yam cuam tshuam rau lub thickness ntawm PCB number case. Qhov kub thiab txias ib puag ncig tuaj yeem txhawb nqa qhov nrawm nrawm ntawm tus number case thiab ua kom cov tuab ntawm txheej. Qhov chaw ntub dej tuaj yeem ua rau tus number case poob viscosity thiab fluidity, cuam tshuam rau lub thickness thiab uniformity ntawm txheej.
