Kungani amabhodi esekethe edinga ukupendwa
Izinhlangothi zangaphambili nangemuva zesekethe ye-pcb ngokuyisisekelo ziyizingqimba zethusi. Ekwenziweni kwamasekethe e-pcb, kungakhathaliseki ukuthi ungqimba lwethusi lukhethelwe isilinganiso sezindleko eziguquguqukayo noma ukungezwa okunamadijithi amabili kanye nokususa, umphumela wokugcina uwubushelelezi nobungenakulungiswa. Nakuba ama-phys...Funda kabanzi -
Ukuvimbela i-welding porosity ekukhiqizeni kwe-PCBA
1. Bhaka ama-PCBA substrates kanye nezingxenye ezingazange zisetshenziswe isikhathi eside futhi zivezwe emoyeni zingaqukatha umswakama. Wabhake ngemva kwesikhathi esithile noma ngaphambi kokusetshenziswa ukuze uvimbele umswakama ukuthi ungaphazamisi ukucubungula kwe-PCBA. 2. I-Solder Paste I-Solder inamathisela nayo ibaluleke kakhulu ekucubunguleni ...Funda kabanzi -
Isidingo esiphansi somkhakha we-PCB
Ukwanda kokungena kwe-5G kanye ne-automotive electronics kuzoletha umfutho wokukhula kwesikhathi eside embonini ye-PCB, kodwa ngaphansi kwethonya lobhubhane lwango-2020, isidingo sama-electronics abathengi nama-PCB ezimoto sisazokwehla, kanye nesidingo sama-PCB kwezokuxhumana ze-5G kanye medical f...Funda kabanzi -
Izindlela ezijwayelekile zokugcinwa kwebhodi lesifunda
1. Indlela yokuhlola ukubukeka ngokubheka ukuthi ibhodi lesekethe linazo yini izindawo ezishisiwe, noma ngabe i-copper plating iphukile, ukuthi kukhona iphunga ebhodini lesekethe, ukuthi azikho yini izindawo zokusoda, ukuthi i-interface neminwe yegolide imnyama noma imhlophe, njll. 2. Okujwayelekile ...Funda kabanzi -
Uyini umehluko phakathi kwesignali ye-vector nomthombo wesiginali ye-RF?
Umthombo wesignali unganikeza amasignali okuhlola anembile futhi azinze kakhulu ezingxenyeni ezihlukahlukene kanye nezinhlelo zokuhlola zesistimu. Ijeneretha yesiginali yengeza umsebenzi wokushintshashintsha onembile, ongasiza ukulingisa isignali yesistimu nokwenza ukuhlola kokusebenza komamukeli. Kokubili isignali ye-vector kanye ne-R...Funda kabanzi -
Isendlalelo sohlelo lokusebenza lwe-Flexible Electronics ku-RFID
Ubuchwepheshe be-Radio frequency identification (RFID) bunezici zokufaka nokucubungula ulwazi oluphelele ngaphandle kokuthintana ngezandla, ukusebenza okusheshayo nokulula, ukuthuthukiswa okusheshayo, njll. Busetshenziswa kakhulu ekukhiqizeni, ekuphatheni impahla, kwezokuthutha, ekwelapheni, ekudleni nasekulweni nekhawunta. ..Funda kabanzi -
I-Solar Cell enefilimu encane
Ifilimu elizacile iseli solar (ifilimu elizacile iseli solar) ingesinye isicelo esithile sobuchwepheshe be-elekthronikhi obuguquguqukayo. Emhlabeni wanamuhla, amandla asephenduke isihloko esikhathaza umhlaba wonke, futhi iChina ayibheki nje kuphela ukuntuleka kwamandla, kodwa futhi nokungcoliswa kwemvelo. Amandla elanga, njengohlobo lwe-ene ehlanzekile...Funda kabanzi -
Yiziphi izici ezithinta i-PCB impedance?
Ngokuvamile, izici ezithinta isici se-PCB yizi: ukushuba kwe-dielectric H, ukujiya kwethusi T, ububanzi bokulandelela u-W, isikhala sokulandelela, i-dielectric engaguquki Er yezinto ezikhethelwe isitaki, kanye nogqinsi lwemaski ye-solder. Ngokuvamile, i-dielectri inkulu ...Funda kabanzi -
Kungani kudingeka ukumboza ngegolide PCB
