Kuyini ukuhlolwa kwe-flying probe yebhodi lesekethe? Lenzani? Lesi sihloko sizokunikeza incazelo eningiliziwe yokuhlolwa kwe-flying probe yebhodi lesifunda, kanye nomgomo wokuhlolwa kwe-flying probe kanye nezici ezibangela ukuthi imbobo ivinjwe. Phrezenta.
Isimiso sokuhlolwa kwe-flying probe yebhodi lesifunda silula kakhulu. Idinga kuphela ama-probe amabili ukuhambisa u-x, y, z ukuhlola izindawo ezimbili zokugcina zesekethe ngayinye ngayinye, ngakho-ke asikho isidingo sokwenza izinto ezibizayo ezengeziwe. Kodwa-ke, ngenxa yokuthi isivivinyo sephuzu lokugcina, isivinini sokuhlola sihamba kancane kakhulu, cishe amaphuzu angu-10-40/isekhondi, ngakho sifaneleka kakhulu amasampula nokukhiqizwa kwenqwaba encane; mayelana nokuminyana kokuhlola, ukuhlolwa kwe-flying probe kungasetshenziswa kumabhodi aminyana kakhulu, njenge-MCM.
Umgomo womhloli ondizayo we-probe: Isebenzisa ama-probe angu-4 ukwenza ukufakwa kwe-high-voltage kanye nokuhlolwa kokuqhubeka kokumelana okuphansi (ukuhlola isekethe evulekile kanye nesifunda esifushane sesekhethi) ebhodini lesifunda, inqobo nje uma ifayela lokuhlola lakhiwe umbhalo wesandla wekhasimende kanye nombhalo wethu wesandla wobunjiniyela.
Kunezizathu ezine zokujikeleza okufushane kanye nesekhethi evulekile ngemuva kokuhlolwa:
1. Amafayela ekhasimende: umshini wokuhlola ungasetshenziswa kuphela ukuqhathanisa, hhayi ukuhlaziya
2. Ukukhiqizwa komugqa wokukhiqiza: I-warpage yebhodi le-PCB, imaski ye-solder, izinhlamvu ezingajwayelekile
3. Inqubo yokuguqulwa kwedatha: inkampani yethu yamukela ukuhlolwa okusalungiswa kobunjiniyela, enye idatha (nge) yokusalungiswa kobunjiniyela ayifakiwe
4. Isici sezinto zokusebenza: izinkinga zesofthiwe ne-hardware
Lapho uthola ibhodi esilihlolile futhi saphumelela isichibi, uhlangabezane nokuhluleka kwe- via hole. Angazi ukuthi yini eyadala ukungaqondi ukuthi asikwazanga ukuyihlola sayithumela ngomkhumbi. Eqinisweni, kunezizathu eziningi zokuhluleka kwe-via hole.
Kunezizathu ezine zalokhu:
1. Ukukhubazeka okubangelwa ukubhoboza: ibhodi lenziwe nge-epoxy resin kanye ne-glass fiber. Ngemuva kokubhoboza umgodi, kuzoba nothuli olusele emgodini, olungahlanzwa, futhi ithusi alikwazi ukucwiliswa ngemva kokuphulukiswa. Ngokuvamile, sihlola inaliti endizayo kuleli cala Isixhumanisi sizohlolwa.
2. Ukukhubazeka okubangelwa ukucwiliswa kwethusi: isikhathi sokucwilisa ithusi sifushane kakhulu, umgodi wethusi awugcwali, futhi umgodi wethusi awugcwali lapho ithini lincibilika, okuholela ezimweni ezimbi. (Emvuleni yamakhemikhali yethusi, kunezinkinga ohlelweni lokususa i-slag, ukuwohloka kwe-alkaline, ukuhushulwa okuncane, ukwenziwa kusebenze, ukusheshisa, nokucwila kwethusi, njengokungathuthuki kahle, ukubhoboza ngokweqile, noketshezi olusele emgodini aluwashwa. clean. Isixhumanisi esiqondile siwukuhlaziya okuthile)
3. Ibhodi lesifunda vias zidinga zamanje ngokweqile, futhi isidingo ukujiyisa imbobo yethusi aziswe kusengaphambili. Ngemuva kokuthi amandla evuliwe, i-current inkulu kakhulu ukuthi ingancibilikisa imbobo yethusi. Le nkinga ivame ukwenzeka. Umsinga wetiyori awulingani nowamanje wangempela. Njengomphumela walokho, ithusi lembobo lancibilika ngokuqondile ngemva kokukhanyisa, okubangele ukuthi i-via ivinjwe futhi kwaba nephutha ngokuthi ayizange ihlolwe.
4. Ukukhubazeka okubangelwa izinga nobuchwepheshe be-SMT tin: Isikhathi sokuhlala esithandweni somlilo side kakhulu ngesikhathi sokushisela, okubangela ukuba imbobo yethusi incibilike, okubangela ukukhubazeka. Abalingani be-Novice, ngokwesikhathi sokulawula, ukwahlulela kwezinto ezibonakalayo akunembile kakhulu , Ngaphansi kokushisa okuphezulu, kukhona iphutha ngaphansi kwezinto ezibonakalayo, okubangela ukuba ithusi lembobo lincibilike futhi lihluleke. Ngokuyisisekelo, imboni yamanje yebhodi ingenza ukuhlolwa kwe-flying probe ye-prototype, ngakho-ke uma ipuleti lenziwa ukuhlolwa kwe-flying probe engu-100%, ukugwema ibhodi ukuthola isandla ukuthola izinkinga. Okungenhla ukuhlaziya ukuhlolwa kwe-flying probe yebhodi lesifunda, ngithemba ukusiza wonke umuntu.
