8 Umaleko HASL Multilayer FR4 PCB
Kutheni le nto iibhodi zePCB ezininzi zizininzi?
Ngenxa yokunqongophala umaleko ophakathi kunye nefoyile, iindleko zemathiriyeli ekrwada ye-PCB engaqhelekanga ingaphantsi kancinane kunoko nakwiPCB.Nangona kunjalo, iindleko zokusetyenzwa kwe-PCB engaqhelekanga yomaleko iphezulu kakhulu kunaleyo yomaleko wePCB.Iindleko zokucutshungulwa komgangatho wangaphakathi ziyafana, kodwa i-foil / i-core structure inyusa kakhulu indleko yokulungiswa kwendawo yangaphandle.
Umnqakathi umaleko PCB kufuneka ukongeza non-standard lamination core inkqubo bonding kwisiseko inkqubo yesakhiwo core.Xa kuthelekiswa nolwakhiwo lwenyukliya, ukusebenza kakuhle kwemveliso yomzi-mveliso onefoil egqunywe ngaphandle kwesakhiwo senyukliya kuya kuncitshiswa.Ngaphambi kwe-lamination, i-core yangaphandle idinga ukucutshungulwa okongeziweyo, oko kwandisa umngcipheko wokukrazula kunye neempazamo ze-etching kumaleko angaphandle.
Iinkqubo ezahlukeneyo zePCB
I-Rigid-Flex PCB
I-Flexible kwaye incinci, yenza lula inkqubo yokuhlanganisa imveliso
Nciphisa izihlanganisi, umthamo wokuthwala umgca ophezulu
Isetyenziswa kwisistim yemifanekiso kunye nezixhobo zonxibelelwano zeRF
I-PCB ye-multilayer
Ubuncinci bobubanzi bomgca kunye nesithuba somgca 3 /3mil
BGA 0.4pitch, umngxuma ubuncinane 0.1mm
Isetyenziswa kulawulo lwamashishini kunye ne-elektroniki yabathengi
I-Impedans Control PCB
Lawula ngokungqongqo ububanzi bomqhubi / ubukhulu kunye nobukhulu obuphakathi
Ukunyamezela ukunyamezela komgca womgca ≤± 5%, ukuhambelana kakuhle kwe-impedance
Ifakwe kwi-high-frequency kunye nezixhobo ezikhawulezayo kunye nezixhobo zonxibelelwano ze-5g
Isiqingatha Umngxuma PCB
Akukho ntsalela okanye ukujikwa kobhedu kwisiqingatha somngxuma
Ibhodi yomntwana yebhodi yomama igcina izihlanganisi kunye nendawo
Ifakwe kwimodyuli yeBluetooth, umamkeli wesignali
