Kutheni ii-PCB eziphelelwe lixesha kufuneka zibhakwe phambi kwe-SMT okanye iziko?
Eyona njongo yokubhaka kwe-PCB kukukhupha amanzi kunye nokususa ukufuma, kunye nokususa ukufuma okukwi-PCB okanye ukufunxwa ngaphandle, kuba ezinye izinto ezisetyenziswa kwi-PCB ngokwayo zenza iimolekyuli zamanzi ngokulula. Ukongeza, emva kokuba iPCB iveliswe kwaye ibekwe ixesha elithile, i...Funda ngokugqithisileyo -
Iimpawu zesiphoso kunye nokugcinwa komonakalo webhodi yesekethe ye-capacitor
Okokuqala, iqhinga elincinci lokuvavanya i-multimeter yokuvavanya amacandelo e-SMT Ezinye iinqununu ze-SMD zincinci kakhulu kwaye azikho lula ukuvavanya nokulungiswa ngeepeni eziqhelekileyo ze-multimeter.

IiCapacitors ziyadlala...Funda ngokugqithisileyo -
Izisombululo zokuhlanjululwa ukuba imboni ye-electroplating kufuneka izazi
Kutheni uhlambulula? 1. Ngethuba lokusetyenziswa kwesisombululo se-electroplating, i-organic by-products iyaqhubeka iqokelela i-2. I-TOC (i-Total Organic Pollution Value) iyaqhubeka nokunyuka, okuya kubangela ukwanda kwenani le-electroplating brightener kunye ne-agent yokulinganisa eyongeziweyo 3. Iziphene kwi ufakwe ngumbane...Funda ngokugqithisileyo -
Amaxabiso efoyile yobhedu ayenyuka, kwaye ukwandiswa kuye kwaba yimvumelwano kushishino lwePCB
Umthamo wasekhaya we-high-frequency kunye ne-high-speed copper clad laminate umthamo wokuvelisa awanelanga. Ishishini le-foil yobhedu liyinkunzi, iteknoloji, kunye neshishini elinetalente elinemiqobo ephezulu yokungena. Ngokwezicelo ezahlukeneyo ezisezantsi, iimveliso zefoyile yobhedu zinokwahlulwa...Funda ngokugqithisileyo -
Zeziphi izakhono zoyilo lwe-op amp circuit PCB?
Ibhodi yesekethe eprintiweyo (i-PCB) i-wiring idlala indima ephambili kwiisekethe zesantya esiphezulu, kodwa idla ngokuba yenye yamanyathelo okugqibela kwinkqubo yoyilo lwesekethe. Kukho iingxaki ezininzi nge-high-speed PCB wiring, kwaye luninzi loncwadi olubhaliweyo ngalo mbandela. Eli nqaku lixoxa ikakhulu ngocingo lwe ...Funda ngokugqithisileyo -
Ungagweba inkqubo yomphezulu we-PCB ngokujonga umbala
nantsi igolide kunye nobhedu kwiibhodi zeesekethe zeeselfowuni kunye neekhompyuter. Ngoko ke, ixabiso lokuphinda lisetyenziswe kwiibhodi zeesekethe ezisetyenzisiweyo linokufikelela ngaphezu kwe-yuan engama-30 ngekhilogram. Kubiza kakhulu kunokuthengisa iphepha elilahliweyo, iibhotile zeglasi, kunye nentsimbi elahliweyo. Ukusuka ngaphandle, umaleko wangaphandle we...Funda ngokugqithisileyo -
Ubudlelwane obusisiseko phakathi koyilo kunye nePCB 2
Ngenxa yeempawu zokutshintsha kombane wokutshintsha, kulula ukubangela unikezelo lombane lokutshintsha ukuvelisa ukuphazamiseka okukhulu kokuhambelana kwe-electromagnetic. Njengenjineli yobonelelo lwamandla, injineli ehambelana ne-electromagnetic, okanye injineli yoyilo lwePCB, kuya kufuneka uqonde i-cau...Funda ngokugqithisileyo -
