εr kwi-1 MHz: ≤5,4 (eqhelekileyo: 4,7) efumaneka ngakumbi ngesicelo
Iminxekile
I-4 ye-School eprintiweyo iprintwe i-schoolbork inama-3 eengqengqelo okanye umaleko womhlaba owenza ukuba i-IT4 ibe zii-IT4.
Zonke ezi zingqiwulo zisetyenziselwa ukuqengqeleka kwemiqondiso.
I-FRST ezimbini zangaphakathi zilele ngaphakathi kwi-core kwaye zihlala zichithwa njengeepaneli zamandla okanye zibizwa ngokuba zihamba ngemiqondiso.
Ukuthetha nje i-4-Wider Stcking Stct une-2 yeStanda VCC kunye nongqimba lomhlaba.
Amanqaku aphambili okuthenga i-PCB
Uninzi lwabathengi bemifanekiso ye-elektroniki badidekile malunga nexabiso le-PCBS. Kwanabanye abantu abaneminyaka emininzi bamava okuthengwa kwe-PCB abanakuqonda ngokupheleleyo isizathu sokuqala. Ngapha koko, ixabiso le-PCB lidityaniswe kwezi zinto zilandelayo:
Okokuqala, amaxabiso ahlukile ngenxa yezixhobo ezahlukeneyo ezisetyenziswa kwi-PCB.
Ukuthatha i-PCB eqhelekileyo ye-PCB njengomzekelo ovela kwi-Fr-4, CEM-3, njl njl nge-0.2mm ukuya kwi-3.6mm. Ubunzima bobhedu luyahluka ukusuka kwi-0.5Oz ukuya kwi-6oz, yonke into ebangele umahluko omkhulu wamaxabiso. Amaxabiso e-Serdermak i-IK kwahlukile kwizixhobo eziqhelekileyo ze-inki kunye ne-Inki ye-inki eluhlaza.
Okwesibini, amaxabiso ahlukile ngenxa yeenkqubo ezahlukeneyo zemveliso.
Inkqubo eyahlukileyo yemveliso ikhokelela kwiindleko ezahlukeneyo. Enje ngeBhodi ePhakathisiweyo yeGolide kunye neBhodi ye-tin, imilo yokutsala kunye nokuhluthwa, ukusetyenziswa kwe-screen ye-screen kunye nemigca yefilimu yefilimu kuya kwenza iindleko ezahlukeneyo, okukhokelela kwixabiso lokwahluka.
