Chaza Ukuhlolwa Okundizayo kwe ibhodi yesifunda ngokuningiliziwe

Umgomo wokuhlolwa kwebhodi lesifunda elindizayo lokuphina ulula kakhulu. Kudinga kuphela ama-probes amabili ukuhambisa u-x, y no-Z ukuvivinya izingxenye zombili zesekethe ngayinye ngakunye, ngakho-ke asikho isidingo sokwenza enye into ebizayo. Kodwa-ke, ngenxa yokuhlolwa kokuphela, isivinini sokulinganisa sihamba kancane, cishe amaphuzu ayi-10 ~ 40 / isekhondi, ngakho-ke kufaneleka kakhulu amasampula nokukhiqizwa kwesisindo esincane; Ngokuya ngobukhulu bokuhlolwa, ukuhlolwa kwenaliti endizayo kungasetshenziswa kumabhodi amakhulu kakhulu, njenge-MCM.

Umgomo wokuhlola inaliti endizayo: ukusebenzisa amasystem amane ukwenza i-high-voltage insulation kanye ne-low resistance conduction test (hlola isekhethi evulekile nesekethe elifushane lomugqa) ebhodini lesifunda, inqobo nje uma idokhumenti yokuhlola yakhiwe ikhasimende lasekuqaleni kanye nokusalungiswa kwethu kobunjiniyela.

Ngemuva kokuhlolwa, kunezizathu ezine zesifunda esifushane nesekethe evulekile:

1. Ifayela lekhasimende: umhloli angaqhathanisa kuphela, angahlaziyi

2.Ukukhiqizwa komugqa wokukhiqiza: i-warpage, ukumelana kwe-solder nezinhlamvu ezingekho ejwayelekile zebhodi le-PCB

3. Inqubo yokuguqulwa kwedatha: inkampani yethu yamukela ukuhlolwa kokulungiswa kobunjiniyela, futhi enye idatha (nge) yedrafti yobunjiniyela iyashiywa

4. Izinsiza kusebenza: Izinkinga zesoftware nezehadiwe

Lapho sithola ibhodi elaphasa isivivinyo sethu futhi salinamathisela, sahlangabezana nokuvinjelwa kwemingxunya esembobeni. Angazi ukuthi kubangelwa yini. Sicabange ngephutha ukuthi bekuyisivivinyo sethu, kepha futhi sathunyelwa. Eqinisweni, kunezizathu eziningi zokuvinjelwa kwembobo.

Kunezizathu ezine zalokhu:

1. Amaphutha abangelwa ukubhola: ipuleti lenziwe nge-epoxy resin glass fiber. Ngemuva kokubhola, kuba nothuli oluyinsalela emgodini, olungahlanzwa, futhi ithusi alinakufakwa ngemuva kokuphulukiswa. Ngokuvamile, sizoyihlola kusixhumanisi sokuhlola inaliti endizayo.

2. Amaphutha abangelwa ukufakwa kwethusi: isikhathi sokubekwa kwethusi sifushane kakhulu, imbobo yethusi ayigcwele, futhi imbobo yethusi ayigcwele lapho kusetshenziswa ithini, okuholela ezimeni ezimbi. (ekubekweni kwethusi kwamakhemikhali, kunenkinga kokuxhumanisa okukodwa kokukhishwa kwe-glue slag, ukususwa kukawoyela we-alkaline, ukufakwa okuncane, ukusebenza, ukusheshisa nokufakwa kwethusi, intuthuko engapheli, ukudonswa ngokweqile, kanye nesisombululo esisele emgodini asigezwa sihlanzekile. Izixhumanisi ezithile zihlaziywa ngokuningiliziwe)

3. Ama-vias ebhodi lesifunda adinga kakhulu manje futhi awaziswanga kusengaphambili ngesidingo sokujiya ithusi lomgodi. Le nkinga ivame ukwenzeka lapho okukhona kukhulu kakhulu ukuthi kungancibilika ithusi lomgodi ngemuva kokuvula amandla. Okwamanje inani lethiyori alilingani nesikhathi samanje, okuholela ekuncibilikeni okuqondile kwembobo yethusi ngemuva kwamandla, okuholela ekungaqhubekeni kwe-via, okucatshangwa ngephutha ukuthi isivivinyo asenziwa.

4. Amaphutha adalwa yikhwalithi nobuchwepheshe betini le-SMT: isikhathi eside sokuhlala esithandweni sikathayela ngesikhathi sokushisela kuholela ekuncibilikeni komgodi wethusi, okuholela emaphutheni. Abalingani be-Novice abanembile kakhulu ekwahluleleni okokusebenza ngokwesikhathi sokulawula, futhi benza amaphutha ngaphansi kwento emazingeni okushisa aphezulu, okuholela ekuhlulekeni kokuncibilika kwethusi lomgodi. Ifektri yamanje yamapuleti ingenza ukuhlolwa kwenaliti ezindizayo kumasampula, ngakho-ke uma ukwenziwa kwepuleti kusatholakala ukuthola ukuhlolwa kwenaliti okundizayo okungu-100% ukugwema izinkinga ezitholakala ezandleni zepuleti.

Isiphetho: ngokufunda, sizokwazi kabanzi ngemininingwane emincane yokuhlolwa kwenaliti endizayo futhi sazi ukuthi singaya kuphi emsebenzini wethu.
