Niaj hnub no lub sijhawm ntawm kev nce qib ntawm kev thev naus laus zis sai, cov khoom siv hluav taws xob hloov tau yooj yim (PCBs) ci zoo li lub hlaws dazzling, ua tau zoo hauv ntau qhov chaw nrog lawv qhov zoo. Yog li, lawv ua li cas raws nraim li qhov nyias thiab lub zog? Cia peb tshawb nrhiav qhov tsis meej ntawm lawv cov txheej txheem tsim khoom tseem ceeb.
Kev tsim cov khoom siv hluav taws xob hloov pauv tau pib nrog kev xaiv cov khoom siv. Ib qho tshwj xeeb polymer substrate yog qhov tseem ceeb; nws ua raws li lub hauv paus ruaj khov, muab lub rooj tsav xwm hauv Circuit Court nrog lub hauv paus hloov tau yooj yim tsis tau muaj zog. Cov khoom siv no yuav tsum tsis yog tsuas yog muaj kev hloov pauv tau zoo xwb tab sis kuj tseem muaj cov khoom siv hluav taws xob zoo los xyuas kom ruaj khov thiab ua haujlwm tau zoo. Ib yam li kev tsim tus choj ruaj khov, siab - cov khoom siv hauv tsev zoo yog qhov tseem ceeb.
Cov ntaub ntawv zoo ib leeg tsis txaus; cov txheej txheem ua tiav yog qhov tseem ceeb. Thaum lub sijhawm tsim khoom, kev siv tshuab thev naus laus zis thev naus laus zis tau ua haujlwm, zoo li tus kws tshaj lij kev kos duab zoo nkauj sculpting. Los ntawm qhov raug raug thiab etching, cov qauv Circuit Court tau zoo tag nrho xa mus rau hauv lub substrate, txhua kab yog qhov tseeb thiab raug-zoo li tsim cov duab zoo nkauj hauv lub ntiaj teb microscopic.
Txhawm rau ua tiav nws cov khoom muaj zog thiab muaj zog, cov txheej txheem lamination tshwj xeeb ua lub luag haujlwm tseem ceeb. Ntau txheej txheej ntawm cov ntaub ntawv yog cleverly stacked thiab nias ua ke, nruj nreem khi lawv kom muab lub Circuit Court board txaus lub zog thiab stability thaum tuav nws yooj. Qhov no zoo ib yam li kev xaws ntau cov khaubncaws sab nraud povtseg ntawm cov xov muaj zog ua ke los tsim lub zog muaj zog.
Tsis tas li ntawd, cov txheej txheem tswj kev ua haujlwm zoo thaum tsim khoom yog qhov tseem ceeb. Los ntawm kev tshuaj xyuas cov ntaub ntawv raw mus rau qhov kev sim nruj tom qab txhua tus txheej txheem, txhua lub rooj tsav xwm hloov pauv tau raug lees paub kom ua tau raws li cov qauv zoo. Tsuas yog los ntawm kev tswj xyuas zoo ntawm txhua theem tuaj yeem ua tau zoo tshaj ntawm cov khoom kawg tau lav.
Cov tub ntxhais siv thev naus laus zis ntawm kev tsim hluav taws xob hloov pauv hluav taws xob yog qhov ua tiav ntawm kev tshawb fawb thiab thev naus laus zis. Nws yog cov txheej txheem me me tab sis tseem ceeb tshaj plaws uas sib sau ua ke nws qhov tshwj xeeb ntxim nyiam ntawm kev nyias nyias tsis muaj zog, ua rau nws ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv thaj chaw xws li cov khoom siv hluav taws xob thiab kev tsav tsheb thev naus laus zis.
