8 Txheej HASL PCB
Vim li cas Multilayer PCB Boards feem ntau txawm tias?
Vim tias tsis muaj txheej txheej nruab nrab thiab ntawv ci, tus nqi ntawm cov ntaub ntawv nyoos rau khib PCB yog me ntsis qis dua qhov ntawd rau PCB.Txawm li cas los xij, tus nqi ua haujlwm ntawm khib txheej PCB yog qhov siab dua li ntawm cov txheej txheem PCB.Tus nqi ua haujlwm ntawm cov txheej txheej sab hauv yog tib yam, tab sis cov ntawv ci / core qauv ua rau nce nqi ntawm txheej txheej txheej.
Odd txheej PCB yuav tsum tau ntxiv cov txheej txheem lamination uas tsis yog txheej txheem txheej txheem kev sib txuas ntawm cov txheej txheem tseem ceeb.Piv nrog rau cov qauv nuclear, kev ua haujlwm ntawm cov nroj tsuag nrog cov ntawv ci txheej sab nraud ntawm cov qauv nuclear yuav raug txo.Ua ntej lamination, cov tub ntxhais sab nrauv yuav tsum tau ua ntxiv, uas ua rau muaj kev pheej hmoo ntawm khawb thiab etching tsis raug ntawm txheej txheej.
Ntau yam ntawm cov txheej txheem PCB
Rigid-Flex PCB
Flexible thiab nyias, simplifying cov khoom sib dhos txheej txheem
Txo cov connectors, siab kab nqa peev xwm
Siv nyob rau hauv cov duab system thiab RF kev sib txuas lus khoom
Multilayer PCB
Tsawg kawg kab dav thiab kab sib nrug 3/3mil
BGA 0.4 pitch, qhov tsawg kawg nkaus qhov 0.1mm
Siv rau hauv kev lag luam tswj thiab cov neeg siv khoom siv hluav taws xob
Impedance Tswj PCB
nruj me ntsis tswj tus neeg xyuas pib dav / thickness thiab nruab nrab thickness
Impedance linewidth kam rau ua ≤ ± 5%, zoo impedance txuam
Siv rau high-frequency thiab high-ceev cov cuab yeej thiab 5g cov khoom sib txuas lus
Ib nrab qhov PCB
Tsis muaj residual los yog warping ntawm tooj liab pos nyob rau hauv ib nrab qhov
Cov me nyuam lub rooj tsavxwm ntawm niam lub rooj zaum txuag cov connectors thiab qhov chaw
Siv rau Bluetooth module, teeb liab receiver
