Basic tswvyim ntawm pcb multilayer board

PCB multi- txheej board hais txog ntau- txheej Circuit Court board siv hauv cov khoom siv hluav taws xob, thiab ntau- txheej board siv ntau dua ib zaug- sab lossis ob sab{{4 }} cov kab hluav taws xob sab. Lub rooj tsav xwm luam tawm nrog ib ob - sab hauv txheej, ob txheej ib zaug - sab nrauv txheej, lossis ob ob ob - sab hauv txheej thiab ob txheej ib zaug - sab nraud, alternated los ntawm positioning system thiab insulating bonding khoom, thiab conductive qauv. Cov ntawv luam tawm Circuit Board uas sib cuam tshuam raws li kev tsim qauv yuav dhau los ua plaub- txheej thiab rau - txheej luam ntawv Circuit Court boards, tseem hu ua ntau- txheej luam ntawv Circuit Court boards

Nrog kev txhim kho tas mus li ntawm SMT (Surface Mount Technology) thiab kev nthuav qhia tas mus li ntawm ib tiam tshiab ntawm SMD (Nto Mount Devices), xws li QFP, QFN, CSP, BGA (tshwj xeeb tshaj yog MBGA), cov khoom siv hluav taws xob tau ua kom ntse thiab me me, yog li Nws tau txhawb txoj kev hloov pauv loj thiab kev nce qib ntawm PCB kev lag luam thev naus laus zis. Txij li thaum IBM tau ua tiav thawj zaug tsim lub siab - ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom microplates. Txoj kev loj hlob sai ntawm cov thev naus laus zis ua haujlwm no tau ua rau PCB tsim kom maj mam txhim kho nyob rau hauv cov kev taw qhia ntawm ntau- txheej thiab siab - xov hlau. Multilayer printed boards tau siv dav hauv kev tsim cov khoom siv hluav taws xob vim lawv cov qauv tsim, ruaj khov thiab txhim khu kev qha hluav taws xob thiab kev ua haujlwm zoo tshaj plaws.
