Izinto eziyi-7 okufanele uzazi mayelana nesakhiwo sesekhethi enesivinini esikhulu
01 Okuhlobene nesakhiwo samandla Amasekhethi edijithali ngokuvamile adinga amaza angasaqhubeki, ngakho ama-inrush currents akhiqizelwa amadivayisi athile anesivinini esikhulu.Uma umkhondo wamandla umude kakhulu, ukuba khona kwe-inrush current kuzodala umsindo we-high-frequency, futhi lo msindo we-high-frequency uzongeniswa kwezinye...Funda kabanzi -
Yabelana ngezinyathelo ezingu-9 zokuvikela i-ESD yomuntu siqu
Kusukela emiphumeleni yokuhlola yemikhiqizo ehlukene, kutholakala ukuthi le ESD iyisivivinyo esibaluleke kakhulu: uma ibhodi lesifunda lingaklanyelwe kahle, lapho kwethulwa ugesi omile, kuzokwenza ukuthi umkhiqizo uphahlazeke noma ulimaze izingxenye.Esikhathini esedlule, ngaqaphela kuphela ukuthi i-ESD izolimaza ...Funda kabanzi -
Ngokubhoboza imbobo, ukuvikela i-electromagnetic kanye nobuchwepheshe be-laser sub-board yebhodi elithambile le-antenna engu-5G
Ibhodi elithambile le-antenna ye-5G&6G ibonakala ngokukwazi ukuthwala ukudluliselwa kwesignali yemvamisa ephezulu kanye nekhono elihle lokuvikela isignali yokuqinisekisa ukuthi isignali yangaphakathi ye-antenna inokungcoliswa okuncane kogesi endaweni yangaphandle ye-electromagnetic, futhi ingafaka...Funda kabanzi -
I-FPC hole metallization kanye nenqubo yokuhlanza ubuso be-copper foil
Inqubo yokukhiqiza ye-FPC enezimbobo enezinhlangothi ezimbili Ukwenziwa kwensimbi kwembobo yamabhodi aphrintiwe avumelanayo ngokuyisisekelo kuyafana naleyo yamabhodi aqinile aphrintiwe.Eminyakeni yamuva nje, kube nenqubo ye-electroplating eqondile ethatha indawo yokufakwa kwe-electroless futhi yamukela ubuchwepheshe bokwenza...Funda kabanzi -
Kungani i-PCB inezimbobo embotsheni yokufakwa odongeni?
Ukwelashwa ngaphambi kokucwila kwethusi 1. Ukuqothula: I-substrate ihamba ngenqubo yokumba ngaphambi kokucwila kwethusi.Nakuba le nqubo ithambekele kuma-burrs, iyingozi ecashile ebaluleke kakhulu ebangela i-metalization yezimbobo eziphansi.Kumele isebenzise indlela yobuchwepheshe yokukhipha imali ukuze ixazulule.Okujwayelekile...Funda kabanzi -
Wazi kangakanani nge-crosstalk ekwakhiweni kwe-PCB enesivinini esikhulu
Enqubweni yokufunda yedizayini ye-PCB enesivinini esikhulu, i-crosstalk umqondo obalulekile odinga ukucaciswa kahle.Kuyindlela eyinhloko yokusabalalisa ukuphazamiseka kwe-electromagnetic.Imigqa yesiginali engavumelaniyo, imigqa yokulawula, nezimbobo ze-I\O zihanjiswa umzila.I-Crosstalk ingabangela ukusebenza okungavamile kwe-circ...Funda kabanzi -
Ingabe wenze konke okulungile ukuze ulinganisele indlela yokuklama isitaki se-PCB?
Umklami angase aklame ibhodi lesifunda eliphrintiwe elinezinombolo ezingavamile (PCB).Uma i-wiring ingadingi isendlalelo esengeziwe, kungani siyisebenzisa?Ingabe ukwehlisa izendlalelo ngeke kwenze ibhodi lesifunda libe mncane?Uma kunebhodi lesifunda elilodwa elincane, ngeke yini izindleko zibe phansi?Nokho, kwezinye izimo, ukwengeza ...Funda kabanzi -
Ungayiphula kanjani inkinga yefilimu ye-PCB electroplating sandwich?
