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
1. I-Surface ye-PCB: I-OSP, i-HASL, i-HASL engenamthofu, i-Immersion Tin, i-ENIG, i-Immersion Silver, i-hard gold plating, Ukucwenga igolide lebhodi lonke, umunwe wegolide, i-ENEPIG... OSP: izindleko eziphansi, ukudayiswa okuhle, izimo ezinzima zokugcina, isikhathi esifushane, ubuchwepheshe bezemvelo, ukushisela okuhle, bushelelezi… HASL: imvamisa kuba...Funda kabanzi -
Ukuhlukaniswa kwama-resistors
1. Izinqamuleli zenxeba ngocingo: izinqamuleli zenxeba zocingo ezijwayelekile, izinqamuleli zenxeba zocingo ezinembayo, izinqamuleli zenxeba zocingo ezinamandla aphezulu, izinto ezivimbela inxeba lezintambo zocingo.2. Izihluthulelo zefilimu ezacile: izinto ezimelana nefilimu ye-carbon, izithasiselo zefilimu zokwenziwa zekhabhoni, izihlungi zefilimu yensimbi, izithasiselo zefilimu ye-oxide yensimbi, ...Funda kabanzi -
I-Varactor diode
I-varactor diode iyi-diode ekhethekile eklanywe ngokukhethekile ngokuvumelana nesimiso sokuthi amandla okuhlangana "we-PN junction" ngaphakathi kwe-diode evamile angashintsha ngokushintsha kwamandla okuguqula asetshenzisiwe.I-varactor diode isetshenziswa kakhulu ku-high-frequency modulatio...Funda kabanzi -
Inductor
I-Inductor ivame ukusetshenziswa kusekethe “L” kanye nenombolo, njengokuthi: L6 isho inombolo ye-inductance engu-6. Amakhoyili aguquguqukayo enziwa ngokusonta izintambo ezivalekile azungeze inani elithile lokujika kuhlaka lwamathambo avaleleke.I-DC ingadlula kukhoyili, ukumelana ne-DC ukumelana kwe ...Funda kabanzi -
I-Capacitor
1. I-capacitor ngokuvamile imelelwa izinombolo ezithi “C” plus kusekethe (njenge-C13 isho ukuthi i-capacitor enomboro 13).I-capacitor yenziwe ngamafilimu amabili ensimbi eduze komunye nomunye, ahlukaniswe yi-insulating material phakathi.Izici ze-capacitor yile ...Funda kabanzi -
Amakhono okusebenza okuhlolwa kwe-PCB endizayo
Lesi sihloko sizokwabelana ngamasu afana nokuqondanisa, ukulungisa, nokuhlola ibhodi le-warping emisebenzini yokuhlola i-flying probe ukuze kusetshenziswe ireferensi kuphela.1. I-Counterpoint Into yokuqala okufanele ukhulume ngayo ukukhethwa kwama-counterpoints.Ngokuvamile, izimbobo ezimbili kuphela ze-diagonal okufanele zithathwe njengama-counterpoints.?)

Izinyathelo zokuthuthukisa isekethe emfishane ye-PCB -isifunda esifushane sendawo
Isizathu esiyinhloko ukuthi kukhona ukuklwebheka emugqeni wefilimu noma ukuvaleka esikrinini esimboziwe, futhi ithusi eliveziwe endaweni engaguquki yongqimba olunamekwe lokulwa nokucwebezela libangela i-PCB ukuthi ihambe kancane.Thuthukisa izindlela: 1. Ifilimu engemihle akumele ibe ne-trachoma, imihuzuko, njll. Ifilimu yezidakamizwa ...Funda kabanzi -
Izici ze-PCB micro-hole mechanical drilling
Kulezi zinsuku, ngokubuyekezwa okusheshayo kwemikhiqizo ye-elekthronikhi, ukuphrinta kwama-PCB kunwetshiwe kusukela kumabhodi angaphambili anesendlalelo esisodwa kuya kumabhodi anezingqimba ezimbili kanye namabhodi anezingqimba eziningi anezidingo zokunemba okuphezulu.Ngakho-ke, kunezidingo ezengeziwe zokucubungula ibhodi lesifunda ...Funda kabanzi -
Ezinye izimiso ezincane zenqubo yokukopisha ye-PCB
1: Isisekelo sokukhetha ububanzi bocingo oluphrintiwe: ububanzi obuncane bocingo oluphrintiwe buhlobene namanje ogeleza ngocingo: ububanzi bomugqa buncane kakhulu, ukumelana kocingo oluphrintiwe kukhulu, kanye nokwehla kwamandla kagesi. emgqeni mkhulu, othinta ukusebenza kwe...Funda kabanzi -
Kungani i-PCB yakho ibiza kangaka?(II)
4.Ukujiya okuhlukile kwefoyili yethusi kubangela ukwehluka kwentengo (1) Uma lincane inani, intengo ibiza kakhulu, ngoba noma wenza i-1PCS, ifektri yebhodi kufanele yenze ulwazi lobunjiniyela, futhi ngaphandle kwefilimu, akukho nqubo edingekayo. kudingekile.(2) Isikhathi sokulethwa: Idatha yokulethwa...Funda kabanzi
