Wopanga PCB Wopikisana

Kodi gulu lozungulira lamitundu yambiri ndi chiyani, ndipo maubwino a gulu lozungulira la PCB lamitundu yambiri ndi chiyani?Monga momwe dzinalo likusonyezera, bolodi yozungulira yamagulu ambiri imatanthawuza kuti bolodi lozungulira lomwe lili ndi zigawo ziwiri zikhoza kutchedwa multilayer.Ndasanthula zomwe gulu loyang'ana mbali ziwiri lidalipo kale, ndipo gulu lozungulira lamitundu yambiri limaposa zigawo ziwiri, monga zigawo zinayi, zigawo zisanu ndi chimodzi, pansi pachisanu ndi chitatu ndi zina zotero.Zoonadi, mapangidwe ena ndi mabwalo osanjikiza atatu kapena asanu, omwe amatchedwanso ma board a PCB amitundu yambiri.Chachikulu kuposa conductive mawaya chithunzi cha bolodi wosanjikiza awiri, zigawo analekanitsidwa ndi insulating magawo.Pambuyo pa gawo lililonse la mabwalo asindikizidwa, gawo lililonse la mabwalo limakutidwa ndi kukanikiza.Pambuyo pake, mabowo akubowola amagwiritsidwa ntchito kuti azindikire kuyendetsa pakati pa mizere ya gawo lililonse.
The ubwino Mipikisano wosanjikiza matabwa ozungulira PCB ndi kuti mizere akhoza anagawira zigawo angapo, kotero kuti mankhwala enieni akhoza kupangidwa.Kapena zinthu zing'onozing'ono zimatha kuzindikirika ndi matabwa amitundu yambiri.Monga: matabwa ozungulira mafoni, ma projekiti ang'onoang'ono, zojambulira mawu ndi zinthu zina zazikulu.Kuphatikiza apo, zigawo zingapo zimatha kukulitsa kusinthasintha kwa mapangidwe, kuwongolera bwino kwa impedance yosiyanitsidwa ndi kutsekeka komaliza, komanso kutulutsa bwino kwa ma frequency amtundu wina.
Multilayer circuit board ndi chinthu chosapeŵeka cha chitukuko cha teknoloji yamagetsi molunjika pa liwiro lalikulu, ntchito zambiri, mphamvu zazikulu ndi voliyumu yaying'ono.Ndi chitukuko chosalekeza chaukadaulo wamagetsi, makamaka kugwiritsa ntchito mozama komanso mozama mabwalo ophatikizika akuluakulu komanso opitilira muyeso, mabwalo osindikizidwa amitundu yambiri akukula mwachangu potengera kuchuluka kwa kachulukidwe, kulondola kwambiri, komanso manambala apamwamba. ., Akhungu dzenje kukwiriridwa dzenje mkulu mbale makulidwe kabowo chiŵerengero ndi matekinoloje ena kukwaniritsa zosowa za msika.
Chifukwa chosowa mabwalo othamanga kwambiri pamakompyuta ndi mafakitale apamlengalenga.Zimafunikanso kuonjezera kachulukidwe ka ma CD, kuphatikizapo kuchepetsa kukula kwa zigawo zolekanitsidwa ndi chitukuko chofulumira cha microelectronics, zipangizo zamagetsi zikukula kuti zichepetse kukula ndi khalidwe;chifukwa cha kuchepa kwa malo omwe alipo, sizingatheke kwa matabwa a mbali imodzi ndi awiri osindikizidwa Kuwonjezeka kwina kwa kachulukidwe ka msonkhano kumatheka.Choncho, m'pofunika kuganizira kugwiritsa ntchito maulendo osindikizidwa kwambiri kuposa zigawo ziwiri.Izi zimapanga mikhalidwe yowonekera kwa matabwa ozungulira ma multilayer.
