Yintoni i-SMT kunye ne-DIP?
I-SMT ibhekiselele kubuchwepheshe bokunyuka komphezulu, okuthetha ukuba amacandelo e-elektroniki abethelwa kwibhodi yePCB ngokusebenzisa izixhobo, kwaye ke amacandelo amiselwe kwibhodi yePCB ngokufudumeza eziko.I-DIP yinxalenye efakwe ngesandla, njengezinye izihlanganisi ezinkulu, izixhobo azikwazi ukubethelwa ...Funda ngokugqithisileyo -
Umahluko phakathi kwe-oven yokubuyisela kunye ne-wave soldering.
1. I-Wave soldering yinkqubo apho i-solder etyhidiweyo yenza i-solder wave ukuya kumacandelo e-solder;i-reflow soldering yinkqubo apho ubushushu obuphezulu bomoya oshushu bubumba i-reflow solder enyibilikayo kumacandelo e-solder.2. Iinkqubo ezahlukeneyo: I-Flux kufuneka itshizwe kuqala kwi-wave soldering, kwaye emva koko ...Funda ngokugqithisileyo -
Yeyiphi imiba ekufuneka inikwe ingqwalasela kwinkqubo ye-reflow soldering?
1. Cwangcisa i-curve ye-soldering ye-reflow efanelekileyo kwaye wenze uvavanyo lwexesha langempela lwe-curve yobushushu rhoqo.2. Weld ngokwendlela welding yoyilo PCB.3. Ukuthintela ngokungqongqo ibhanti lokuhambisa ukuba lingcangcazele ngexesha lenkqubo ye-welding.4. Isiphumo sewelding yebhodi eprintiweyo m...Funda ngokugqithisileyo -
Umgaqo we-oven yokubuyisela kwakhona
I-oven yokubuyisela kwakhona kukuthengiswa koqhagamshelo lomatshini kunye nombane phakathi kokupheliswa okanye izikhonkwane zezinto zokuxhoma ngaphezulu kunye neepadi zebhodi eziprintiweyo ngokunyibilikisa i-solder elayishiweyo ngaphambili esasazwe kwiipadi zebhodi eziprintiweyo.I-Reflow soldering kumacandelo e-solder kwi-PCB boa...Funda ngokugqithisileyo -
Yintoni umatshini wokuthambisa wamaza?
Ukuthengiswa kwamaza kuthetha ukuba i-solder etyhidiweyo (i-lead-tin alloy) itshizwa kwi-solder wave crest efunwa luyilo ngempompo yombane okanye impompo ye-electromagnetic.Ibhodi idlula kwi-solder wave crest kwaye yenza incopho ye-solder yesimo esithile kwinqanaba le-solder liquid.I...Funda ngokugqithisileyo -
I-Solder ekhethiweyo vs i-Wave Solder
I-Wave Solder Inkqubo eyenziwe lula yokusebenzisa umatshini we-solder yamaza: Okokuqala, umaleko we-flux utshizwe ngaphantsi kwebhodi ekujoliswe kuyo.Injongo ye-flux kukucoca kunye nokulungiselela amacandelo kunye ne-PCB ye-soldering.Ukuthintela ukothuka kwe-thermal ibhodi ifudumeza kancinane ngaphambi kokuba ifakwe i-solder...Funda ngokugqithisileyo -
