εr e-1 MHz: ≤5,4 (eqhelekileyo: 4,7) Okunye okufumanekayo ngesicelo
Iminxekile
I-4 layer eprintiweyo ye-circuitboard stackup ine-3 yemigangatho enye kunye ne-ground layer eyenza i-4 layers iyonke.
Zonke ezi maleko zisetyenziselwa ukuhanjiswa kwemiqondiso.
Iilava ezimbini zokuqala zangaphakathi zilele ngaphakathi kumbindi kwaye zihlala zisetyenziswa njengeepaneli zombane okanye ziqhele ukubizwa ngokuba kukuhamba kwemiqondiso.
Ukuthetha nje i-4-layer PCB stackup ine-2 ye-single VCC kunye nomgangatho womhlaba.
Amanqaku aphambili okuthenga i-pcb
Uninzi lwabathengi befektri ye-elektroniki babhidekile malunga nexabiso lePCBs.kwanabanye abantu abaneminyaka emininzi yamava kwi-PCB yokuthenga banokungasiqondi ngokupheleleyo isizathu sokuqala.Ngapha koko, ixabiso lePCB liqulunqwe zezi zinto zilandelayo:
Okokuqala, amaxabiso ahlukile ngenxa yezinto ezahlukeneyo ezisetyenziswa kwi-PCB.
Ukuthatha iileya eziqhelekileyo eziphindwe kabini pcb njengomzekelo, i-laminate iyahluka ukusuka kwi-FR-4, i-CEM-3, njl njl kunye nobubanzi obusuka ku-0.2mm ukuya kwi-3.6mm.Ubunzima bobhedu buhluka ukusuka kwi-0.5Oz ukuya kwi-6Oz, konke oku kubangele umahluko omkhulu wexabiso.Amaxabiso e-inki ye-soldermask nawo ahluke kwizinto eziqhelekileyo ze-inki ze-thermosetting kunye ne-photosensitive eluhlaza izinto ze-inki.
Okwesibini, amaxabiso ahluke ngenxa yeenkqubo ezahlukeneyo zemveliso.
Iinkqubo ezahlukeneyo zemveliso zikhokelela kwiindleko ezahlukeneyo.Njengebhodi efakwe ngegolide kunye nebhodi efakwe i-tin-plated, imilo yomzila kunye nokubetha, ukusetyenziswa kwemigca yesikrini sesilika kunye nemigca yefilimu eyomileyo iya kwenza iindleko ezahlukeneyo, okukhokelela ekuhlukeni kwexabiso.
