Loluphi uvavanyo lwe-flying probe yebhodi yesekethe? Wenza ntoni? Eli nqaku liza kukunika inkcazo eneenkcukacha zovavanyo lwe-flying probe yebhodi yesekethe, kunye nomgaqo wovavanyo lwe-flying probe kunye nezinto ezibangela ukuba umngxuma uvalwe. Nikela.
Umgaqo webhodi yesekethe yokuvavanya i-probe test ilula kakhulu. Ifuna kuphela iiprobes ezimbini ukushukuma x, y, z ukuvavanya amanqaku amabini esiphelo sesekethe nganye nganye, ngoko akukho mfuneko yokwenza izinto ezongezelelweyo ezibizayo. Nangona kunjalo, ngenxa yokuba luvavanyo lokuphela, isantya sovavanyo sicotha kakhulu, malunga ne-10-40 amanqaku / isekhondi, ngoko ke ifanelekile ngakumbi kwiisampuli kunye nokuveliswa kobunzima obuncinci; ngokwemiqathango yoxinaniso lovavanyo, uvavanyo lwe-flying probe lunokusetyenziswa kwiibhodi zoxinaniso eziphezulu kakhulu, ezifana ne-MCM.
Umgaqo we-flying probe tester: Isebenzisa iiprobes ezi-4 ukwenza i-insulation high-voltage kunye novavanyo oluphantsi lokumelana nokuqhubekayo (ukuvavanya isiphaluka esivulekileyo kunye nesiphaluka esifutshane sesekethe) kwibhodi yesekethe, nje ukuba ifayile yovavanyo yenziwe Umbhalo-ngqangi wabathengi kunye nombhalo wethu wobunjineli.
Kukho izizathu ezine zesekethe emfutshane kunye nesekethe evulekileyo emva kovavanyo:
1. Iifayile zabathengi: umatshini wokuvavanya ungasetyenziselwa ukuthelekisa kuphela, kungekhona ukuhlalutya
2. Ukuveliswa komgca wokuvelisa: I-warpage yebhodi ye-PCB, imaski ye-solder, abalinganiswa abangaqhelekanga
3. Inkqubo yokuguqulwa kwedatha: inkampani yethu ithatha uvavanyo lwedrafti yobunjineli, enye idatha (nge) yoyilo lobunjineli ishiywe
4. Isixhobo sezixhobo: iingxaki zesoftware kunye ne-hardware
Xa wawufumene ibhodi esiyivavanyeyo saza sayiphumelela ipatch, uye wadibana nokusilela komngxuma. Andazi ukuba yintoni ebangele ukungavisisani ukuba singakwazi ukuyivavanya kwaye siyithumele ngenqanawa. Enyanisweni, kukho izizathu ezininzi zokungaphumeleli komngxuma.
Kukho izizathu ezine zoku:
1. Iziphene ezibangelwa yi-drilling: ibhodi yenziwe nge-epoxy resin kunye ne-glass fiber. Emva kokubhoboza umngxuma, kuya kubakho uthuli oluseleyo emngxunyeni, olungacocwanga, kwaye ubhedu alukwazi ukucwiliswa emva kokunyanga. Ngokuqhelekileyo, sihamba ngovavanyo lwenaliti kule meko Ikhonkco iya kuvavanywa.
2. Iziphene ezibangelwa ukucwiliswa kobhedu: ixesha lokucwilisa ubhedu lifutshane kakhulu, ubhedu lomngxuma alugcwali, kwaye ubhedu lomngxuma alugcwali xa i-tin inyibilika, okubangela iimeko ezimbi. (Kwimichiza yemvula yobhedu, kukho iingxaki kwinkqubo yokususa i-slag, i-alkaline degreasing, i-micro-etching, i-activation, i-acceleration, kunye nokucwiliswa kobhedu, ezifana nophuhliso olungaphelelanga, ukubamba ngokugqithiseleyo, kunye nolwelo olushiyekileyo emngxunyeni aluhlanjwanga. coca.
3. Ibhodi yesekethe nge-vias ifuna ngoku ngokugqithisileyo, kwaye imfuno yokutyebisa ubhedu womngxuma ayiziswanga kwangaphambili. Emva kokuba amandla evuliwe, umsinga mkhulu kakhulu ukunyibilikisa ubhedu lomngxuma. Le ngxaki idla ngokwenzeka. Ithiyori yangoku ayilingani neyona yangoku. Ngenxa yoko, ubhedu lomngxuma lwanyibilika ngokuthe ngqo emva kokuvulwa kombane, nto leyo ebangele ukuba i-via ivalwe kwaye kwaphazama ukuba ayivavanywa.
4. Iziphene ezibangelwa ngumgangatho we-tin ye-SMT kunye nobuchwepheshe: Ixesha lokuhlala kwisithando somlilo lide kakhulu ngexesha le-welding, ebangela ukuba ubhedu lomngxuma lunyibilike, olubangela iziphene. Amaqabane e-Novice, ngokwexesha lokulawula, isigwebo sezinto eziphathekayo asichanekanga kakhulu , Ngaphantsi kobushushu obuphezulu, kukho impazamo phantsi kwezinto eziphathekayo, ezibangela ukuba ubhedu lomngxuma luncibilike kwaye lungaphumeleli. Ngokusisiseko, umzi-mveliso webhodi wangoku unokwenza uvavanyo olubhabhayo lweprobe yeprototype, ke ukuba ipleyiti yenziwe 100% yovavanyo lokuhlola olubhabhayo, ukunqanda ukuba ibhodi ifumane isandla ukufumana iingxaki. Oku ngasentla kuhlalutyo lovavanyo lwe-flying probe yebhodi yesiphaluka, ndiyathemba ukunceda wonke umntu.
