Indibano ye-SMT PCB kunye noKhuseleko lwe-ESD: Yonke into ekufuneka uyazi!
Kwihlabathi le Indibano ye-PCB ye-SMT (iTekhnoloji yokuHamba ngaphezulu), ukufikelela kumgangatho ophezulu, iimveliso ze-elektroniki ezithembekileyokufuna okungaphezulu nje kokubekwa ngokuchanekileyo kunye nokutywinwa. Into ebalulekileyo edla ngokungaqatshelwa kodwa enokwenza okanye yaphule ukuthembeka kwe ibhodi yesekethe eprintiweyo (i-PCB)yi Ukukhupha i-Electrostatic (ESD).
Ngaphezulu Iminyaka engama-20, thina apha [Igama leNkampani yakho]bebesebenza phambili Ukuveliswa kwePCBkwaye indibano, kwaye siyazi ukuba ukukhusela izinto umbane ongashukumiyokubaluleke njengokubeka ngokuchanekileyo. Kweli nqaku, siza kungena nzulu kwisayensi engasemva Ukhuseleko lwe-ESDngaphakathi Indibano ye-SMT PCB, kutheni kubalulekile, kunye nendlela yokuyisebenzisa iindlela ezilungileyoukukhusela izinto zakho.
- Yintoni i-Electrostatic Discharge (ESD)?
Ukukhupha i-Electrostatic (ESD)ibhekisa ekuhambeni kombane ngequbuliso phakathi kwezinto ezimbini ezitshajiweyo ngombane. Oku kwenzeka xa itshaja engashukumiyo—nokuba ivela kumntu, kwisixhobo, okanye kwi-PCB engasekelwanga kakuhle—iyakheka ize ikhutshwe ngequbuliso, nto leyo enokonakalisa izinto ze-elektroniki ezibuthathaka kwi-PCB.
Iindibano ze-SMT PCBzisengozini enkulu kwi-ESD kuba zihlala ziqulathe izinto ezincinci, ezinobuthathaka kakhulu ezinokonakala lula nokuba yitshaja encinci ye-electrostatic. umonakaloyenziwe ngu I-ESDkunokubangela oku:
- Ukusilela kwecandelo
- Ukuwohloka kokusebenza
- Ubomi obufutshaneye-PCB okanye izinto zayo
Ngaphandle ukhuseleko olufanelekileyo lwe-ESD, ezi ngozi ziyanda, yiyo loo nto zisebenza ngempumelelo Amanyathelo okulawula i-ESDzibalulekile kwi Indibano yePCB.
- I-ESD iyichaphazela njani iNdibano ye-SMT PCB?
Xa usebenza ne Indibano ye-SMT, izinto ezisetyenzisiweyo—izithinteli, ii-capacitors, iisekethe ezidibeneyo (ii-IC), ngakumbi ii-semiconductors—zinovakalelo olukhulu kwiitshaja ze-electrostatic. Nokuba zincinci kangakanani na i-static electricity zinokuba nemiphumo emibi kakhulu kwezi zinto, nto leyo enokubangela oku kulandelayo:
- Ukungasebenzi kakuhle kwecandelo
- Iisekethe ezingaphelelangangenxa yokudibanisa okonakalayo
- Ukungasebenzi kakuhlekwimveliso yokugqibela
Umonakalo we-ESD unokubangela nayiphi na ukusilela kwangokookanye ukusilela okufihlakeleyo, apho umonakalo ungabonakali ngoko nangoko kodwa ubangela ukuba inxalenye yesixhobo ingasebenzi kakuhle ngaphambi kwexesha. Kumashishini afana izixhobo ze-elektroniki zabathengi, izixhobo zonyangokunye iinkqubo zeemoto, ukuthembekaakunakuxoxiswana ngako. Ngenxa yoko, ukubandakanywa amanyathelo olawulo lwe-ESD asebenzayokubaluleke kakhulu.
