Ndi PCB multilayer ndi chiyani and mikhalidwe yake ndi iti ya bolodi la multilayer?

Multilayer PCB amatanthauza matabwa angapo osanjikiza omwe amagwiritsidwa ntchito popanga zamagetsi. Multilayer PCB imagwiritsa ntchito matabwa angapo osanjikiza kapena amitundu iwiri. Gwiritsani ntchito mbali imodzi iwiri ngati wosanjikiza wamkati, awiri mbali imodzi ngati wosanjikiza wakunja, kapena awiri amagawo awiri ngati wosanjikiza wamkati komanso wosanjikiza awiri ngati bolodi losanjikiza lakunja. Makina osungira ndi zinthu zokutira zosakanikirana mosiyanasiyana pamodzi ndi mawonekedwe amachitidwe Ojambula osindikizidwa omwe amalumikizidwa molingana ndi kapangidwe kake amakhala zigawo zinayi ndi zigawo zisanu ndi chimodzi zosindikizidwa matabwa, omwe amadziwikanso kuti ma board multilayer osindikizidwa. 

Ndikukula kopitilira muyeso kwa SMT (Surface Mount Technology) ndikupititsa patsogolo m'badwo watsopano wa SMD (Zida Zapamwamba Zapamwamba), monga QFP, QFN, CSP, BGA (makamaka MBGA), zamagetsi ndizanzeru kwambiri komanso zazing'ono, kotero Tidalimbikitsa kusintha kwakukulu ndi kupita patsogolo kwaukadaulo wa mafakitale a PCB. Popeza IBM idayamba kupanga ma multilayer (SLC) ambiri mu 1991, magulu akuluakulu mmaiko osiyanasiyana apanganso ma microplates angapo a high-density interconnect (HDI). Kukula mwachangu kwa matekinoloje awa kwapangitsa kuti mapangidwe a PCB azikula pang'onopang'ono polumikizira zingwe zingapo. Ndi kapangidwe kake kosasintha, magwiridwe antchito ndi odalirika pamagetsi komanso magwiridwe antchito achuma, matumba angapo osindikizidwa tsopano amagwiritsidwa ntchito kwambiri pakupanga zamagetsi.
