Ukucatshangelwa kwe-PCB design
Ngokomdwebo wesifunda othuthukisiwe, ukulingisa kungenziwa futhi i-PCB ingaklanywa ngokuthumela ifayela le-Gerber/drill. Noma ngabe imuphi umklamo, onjiniyela badinga ukuqonda kahle ukuthi amasekethe (nezingxenye ze-elekthronikhi) kufanele abekwe kanjani nokuthi asebenza kanjani. Okogesi...Funda kabanzi -
Ukungalungi kokupakishwa okungokwesiko kwe-PCB kwezingqimba ezine
Uma i-interlayer capacitance ingenkulu ngokwanele, inkambu kagesi izosatshalaliswa endaweni enkulu kakhulu yebhodi, ukuze i-impedance ye-interlayer incishiswe futhi i-current yokubuyisela ingageleza ibuyele endaweni ephezulu. Kulokhu, inkambu ekhiqizwe yilesi siginali ingase iphazamise ...Funda kabanzi -
Izimo PCB wesifunda ibhodi Welding
1. I-weldment ine-weldability enhle I-solderability ebizwa ngokuthi i-solderability ibhekisela ekusebenzeni kwe-alloy engakwazi ukwakha inhlanganisela enhle yezinto zensimbi okumele zifakwe kanye ne-solder ekushiseni okufanelekile. Akuzona zonke izinsimbi ezinokushisela okuhle. Ukuze uthuthukise i-solderability, linganisa...Funda kabanzi -
Ukushiselwa kwebhodi le-PCB
I-welding ye-PCB iyisixhumanisi esibaluleke kakhulu ohlelweni lokukhiqiza lwe-PCB, ukushisela ngeke kuthinte ukubonakala kwebhodi lesifunda kuphela kodwa futhi kuthinte ukusebenza kwebhodi lesifunda. Amaphuzu wokushisela webhodi lesifunda le-PCB ami kanje: 1. Lapho ushisela ibhodi le-PCB, qala uhlole ...Funda kabanzi -
Uzilawula kanjani izimbobo ze-HDI ezixinene kakhulu
Njengoba nje izitolo zezingxenyekazi zekhompuyutha zidinga ukuphatha nokubonisa izipikili nezikulufu zezinhlobo ezihlukahlukene, i-metric, impahla, ubude, ububanzi nephimbo, njll., idizayini ye-PCB nayo idinga ukuphatha izinto zokuklama ezifana nezimbobo, ikakhulukazi kumklamo wokuminyana okuphezulu. Imiklamo ye-PCB yosiko ingasebenzisa izimbobo ezimbalwa zokudlula, ...Funda kabanzi -
Ungawabeka kanjani ama-capacitor ekwakhiweni kwe-PCB?
Ama-Capacitor adlala indima ebalulekile ekwakhiweni kwe-PCB enesivinini esikhulu futhi ngokuvamile ayidivayisi esetshenziswa kakhulu ku-PCBS. Ku-PCB, ama-capacitor avame ukuhlukaniswa abe ama-filter capacitors, ama-decoupling capacitors, ama-capacitor okugcina amandla, njll.Funda kabanzi -
Izinzuzo kanye nokubi pcb zethusi enamathela
I-Copper coating, okungukuthi, indawo engenzi lutho ku-PCB isetshenziswa njengezinga lesisekelo, bese igcwaliswa ngethusi eliqinile, lezi zindawo zethusi zibizwa nangokuthi ukugcwaliswa kwethusi. Ukubaluleka kwe-copper coating ukunciphisa i-impedance yomhlabathi nokuthuthukisa ikhono lokulwa nokuphazamiseka. Yehlisa ukwehla kwamandla kagesi, ...Funda kabanzi -
Ukuvala Imbobo Efakwe Electroplated/Ukugcwalisa Ku-Ceramic PCB
Ukuvala imbobo nge-electroplated kuyinqubo evamile yokukhiqiza ibhodi lesifunda ephrintiwe esetshenziselwa ukugcwalisa nokuvala emigodini (ngemigodi) ukuze kuthuthukiswe ukuqhutshwa kukagesi nokuvikelwa. Enqubweni yokukhiqiza ibhodi lesifunda ephrintiwe, imbobo yokudlula iyisiteshi esisetshenziselwa ukuxhuma okuhlukile ...Funda kabanzi -
Kungani amabhodi we-PCB kufanele enze i-impedance?
I-PCB impedance isho imingcele yokumelana nokusabela, edlala indima ye-anobstruction ekushintsheni kwamanje. Ekukhiqizeni ibhodi lesifunda se-pcb, ukwelashwa kwe-impedance kubalulekile. Ngakho-ke uyazi ukuthi kungani amabhodi wesifunda se-PCB adinga ukwenza i-impedance? 1, ibhodi lesifunda le-PCB eliphansi ukuze ucabangele i-ins...Funda kabanzi -
ithini elimpofu
Ukwakhiwa kwe-PCB kanye nenqubo yokukhiqiza inezinqubo ezingaba ngu-20, ithini elimpofu ebhodini lesifunda lingase liholele ku-sandhole yomugqa, ukuwa kocingo, amazinyo ezinja zomugqa, isifunda esivulekile, umugqa we-sand hole; Imbobo yethusi imbobo encane engathí sina ngaphandle kwethusi; Uma imbobo yethusi incane kakhulu, imbobo yethusi i...Funda kabanzi -
Amaphuzu angukhiye wokuqinisa i-DC/DC PCB
Ngokuvamile ukuzwa "ukugxilisa kubaluleke kakhulu", "isidingo sokuqinisa umklamo wokumisa" nokunye. Eqinisweni, kusakhiwo se-PCB seziguquli ze-booster DC/DC, ukwakheka komhlaba ngaphandle kokucatshangelwa okwanele kanye nokuphambuka emithethweni eyisisekelo yimbangela eyinhloko yenkinga.

Izimbangela zokungafakwa kahle kwamabhodi esekethe
1. I-Pinhole I-pinbole ibangelwa ukukhanyiswa kwegesi ye-hydrogen ebusweni bezingxenye ezicwecwe, ezingeke zikhishwe isikhathi eside. Isixazululo sokucwenga asikwazi ukumanzisa ingaphezulu lezingxenye ezipuletiwe, ukuze ungqimba lwe-electrolytic plating lungakwazi ukuhlaziywa ngogesi. Njengoba ubukhulu...Funda kabanzi
