Cov txheej txheem electroplating yog qhov tseem ceeb heev nyob rau hauvHDI Board Raug
Cov txheej txheem hluav taws xob yog cov khoom siv hlau tso rau hauv cov khoom siv hluav taws xob thiab cov txheej txheem hluav taws xob no yuav tsum tau ua rau cov khoom siv hluav taws xob thiab cov teeb meem no yuav tsum muaj kev tswj hwm hluav taws xob circuits .
(10 txheej thawj-xaj HDI Rigid Flex Board)
Hauv cov txheej txheem ntau lawm, tseem yuav muaj ntau cov txheej txheem tshwj xeeb
Piv txwv li, laser drilling, HDI camchs tsis muaj kev siv tshuab hluav taws xob ib txwm muaj thiab siv cov txheej txheem nruj me ntsis, thiab txawm tias muaj kev sib txawv me ntsis yuav cuam tshuam qhov zoo ntawm cov dig muag qhov .
In addition, the difficulty of manufacturing multi-stage HDI boards further increases. Taking a second-order HDI board as an example, it usually requires two presses and at least two laser drills. The second-order HDI board with eight layers may be laminated with 2-9 layers first, then laminated with 1 and 10 layers on the outer layer, and laser drilled ob zaug . cov txheej txheem no ntau dua tsis yog qhov nyuaj ntawm cov txheej txheem, drilling, thiab tooj liab plating .
