Iingqwalasela zoyilo lwePCB
Ngokomzobo wesiphaluka ophuhlisiwe, ukulinganisa kunokwenziwa kwaye i-PCB inokuqulunqwa ngokuthumela ngaphandle ifayile yeGerber / i-drill. Nokuba yeyiphi na uyilo, iinjineli kufuneka ziqonde ngqo ukuba iisekethe (kunye nezinto ze-elektroniki) kufuneka zibekwe njani kwaye zisebenza njani. Yezobuchwephesha...Funda ngokugqithisileyo -
Ukungalungi PCB zemveli umaleko ezine stacking
Ukuba i-interlayer capacitance ayinkulu ngokwaneleyo, intsimi yombane iya kusasazwa kwindawo enkulu yebhodi, ukwenzela ukuba i-impedance ye-interlayer iyancitshiswa kwaye i-current i-return ingabuyela kumqolo ophezulu. Kule meko, umhlaba oveliswe ngulo mqondiso unokuphazamisana ne ...Funda ngokugqithisileyo -
Iimeko PCB welding ibhodi yesekethe
1. I-weldment ine-weldability efanelekileyo Into ebizwa ngokuba yi-solderability ibhekisela ekusebenzeni kwe-alloy enokuthi yenze inhlanganisela efanelekileyo yezinto zetsimbi eziza kuxutywa kunye ne-solder kwiqondo lokushisa elifanelekileyo. Ayizizo zonke iintsimbi ezikwazi ukuwelda kakuhle. Ukuze kuphuculwe i-solderability, linganisa...Funda ngokugqithisileyo -
Welding of PCB board
I-welding ye-PCB likhonkco elibaluleke kakhulu kwinkqubo yokuvelisa ye-PCB, i-welding ayiyi kuchaphazela kuphela ukubonakala kwebhodi yesiphaluka kodwa ichaphazela nokusebenza kwebhodi yesekethe. Amanqaku welding yebhodi yesekethe PCB zezi zilandelayo: 1. Xa welding PCB ibhodi, khangela kuqala ...Funda ngokugqithisileyo -
Uyilawula njani imingxunya yeHDI enoxinano oluphezulu
Kanye njengokuba iivenkile ze-hardware kufuneka zilawule kwaye zibonise izikhonkwane kunye nezikrufu zeentlobo ezahlukeneyo, i-metric, impahla, ubude, ububanzi kunye ne-pitch, njl. Uyilo lwePCB yesiNtu lunokusebenzisa kuphela imingxunya embalwa eyahlukeneyo yokupasa, ...Funda ngokugqithisileyo -
Uzibeka njani iicapacitors kuyilo lwePCB?
IiCapacitors zidlala indima ebalulekileyo kuyilo lwePCB enesantya esiphezulu kwaye zisoloko zisesona sixhobo sisetyenziswa kakhulu kwiPCBS. Kwi-PCB, i-capacitors idla ngokuhlula kwii-filter capacitors, i-decoupling capacitors, i-capacitors yokugcina amandla, njl njl.Funda ngokugqithisileyo -
Izinto eziluncedo kunye nokungonakali pcb copper coating
Ukufakwa kobhedu, oko kukuthi, indawo engasebenziyo kwi-PCB isetyenziswe njengenqanaba lesiseko, kwaye emva koko izaliswe ngobhedu oluqinileyo, ezi ndawo zobhedu zikwabizwa ngokuba nokuzaliswa kobhedu. Ukubaluleka kokugubungela ubhedu kukunciphisa i-impedance yomhlaba kunye nokuphucula amandla okuthintela ukuphazamiseka. Ukunciphisa ukuhla kwamandla ombane, ...Funda ngokugqithisileyo -
Ukutywinwa komngxuma we-Electroplated/Ukuzaliswa kwiCeramic PCB
Ukutywinwa komngxuma we-Electroplated yinkqubo yokwenziwa kwebhodi yesekethe eprintiweyo eqhelekileyo esetyenziselwa ukuzalisa kunye nokutywinwa ngemingxuma (ngemingxuma) ukunyusa ukuhanjiswa kombane kunye nokhuseleko. Kwinkqubo yokuvelisa ibhodi yesekethe eprintiweyo, i-pass-through hole ngumjelo osetyenziselwa ukudibanisa ezahlukeneyo ...Funda ngokugqithisileyo -
Kutheni kufuneka iibhodi zePCB zenze i-impedance?
I-PCB impedance ibhekisa kwiiparamitha zokuchasa kunye nokusabela, ezidlala indima ye-anobstruction ekutshintsheni okwangoku. Kwimveliso yebhodi yesekethe ye-pcb, unyango lwe-impedance luyimfuneko. Ngaba uyazi ukuba kutheni iibhodi zesekethe zePCB kufuneka zenze i-impedance? 1, PCB ibhodi yesekethe ezantsi ukuqwalasela ins...Funda ngokugqithisileyo -
itoti empofu
Uyilo lwePCB kunye nenkqubo yokuvelisa ineenkqubo ezininzi ezingama-20, itoti engalunganga kwibhodi yesekethe inokukhokelela kumgca wesanti, ukudilika kocingo, amazinyo enja yomgca, isekethe evulekileyo, umgca womngxuma wesanti; Pore copper obhityileyo umngxuma olunzulu ngaphandle kobhedu; Ukuba umngxuma ubhedu obhityileyo unzulu, umngxuma ubhedu kunye...Funda ngokugqithisileyo -
Amanqaku aphambili okukhuthaza i-DC/DC PCB
Ngokuqhelekileyo ukuva "ukugxilwa kubaluleke kakhulu", "isidingo sokuqinisa uyilo lokumisa" njalo njalo. Enyanisweni, kwi-PCB layout ye-booster DC / DC converters, i-grounding design ngaphandle kokuqwalaselwa ngokwaneleyo kunye nokuphambuka kwimithetho esisiseko ngunobangela wengxaki.
