PCB Circuit Board yog ib qho tseem ceeb tshaj plaws hauv ntau yam khoom siv hluav taws xob, uas ua lub luag haujlwm txiav txim siab hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob. Hauv kev lag luam hluav taws xob hluav taws xob, ntau dua 60 feem pua ntawm cov PCB boards siv yog multilayer circuit boards, uas qhia txog qhov tseem ceeb ntawm multilayer circuit boards. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, tib neeg pib muaj kev nkag siab zoo ntawm PCB multilayer circuit boards,
Multilayer PCB Manufacturing Txheej txheem cej luam: Hauv qhov tseem ceeb, cov txheej txheem tsim ua raws li tooj liab multilayer PCB manufacturers yog qhov yooj yim heev. Txoj kev tsim khoom yuav tsum tau ua raws li hauv qab no:
Xaiv cov khoom ntawm cov tub ntxhais sab hauv, prepreg thiab tooj liab ntawv ci.
Daim ntawv prepreg yog ua los ntawm iav ntaub thiab epoxy resin.
Cov tub ntxhais laminate yog txuas ntxiv nrog cov ntawv ci tooj liab (Cu) ntawm ib qho hnyav thiab tuab.
Cov khaubncaws sab nraud povtseg yog tom qab ntawd npog nrog cov yeeb yaj kiab photosensitive qhuav uas coj UV teeb rau hauv kev sib cuag nrog cov tiv thaiv. Los ntawm kev siv lub teeb UV, cov ntaub ntawv hluav taws xob los ntawm cov hluav taws xob sab hauv raug xa mus rau qhov photoresist.
