I-Solder mast iyingxenye ebaluleke kakhulu yamabhodi wesifunda aphrintiwe we-PCB, Akungabazeki ukuthi imaski ye-Solder izosiza ekuhlanganiseni, noma kunjalo yini enye imaski ye-solder efaka isandla kuyo?Kuzodingeka sazi kabanzi mayelana ne-solder mask ngokwayo.
Iyini imaski ye-solder?
Imaski yokumisa i-solder noma imaski yokumisa i-solder noma ukumelana ne-solder ungqimba oluncane lwe-lacquer olufana ne-polymer oluvame ukusetshenziswa emithonjeni yethusi yebhodi lesifunda eliphrintiwe (PCB) ukuze kuvikelwe ekufakweni kwe-oxid nokuvikela amabhuloho athengisa ukuthi akheke phakathi kwamaphedi okuthengisa asondelene. .
Ibhuloho le-solder ukuxhumana kukagesi okungahlosiwe phakathi kwamakhondakta amabili ngokusebenzisa ibhuloho elincane le-solder.
Ama-PCB asebenzisa imaski ye-solder ukuvimbela lokhu ukuthi kungenzeki.
Imaski ye-Solder ayihlali isetshenziselwa imihlangano edayiswa ngesandla, kodwa ibalulekile kumabhodi akhiqizwa ngobuningi adayiswa ngokuzenzakalelayo kusetshenziswa amasu okugeza okugeleza kabusha noma okudayiswa.
Uma sekusetshenziswe, ukuvuleka kufanele kwenziwe kumaski e-solder nomaphi lapho izingxenye zithengiswa khona, okufezwa ngokusebenzisa i-photolithography.
Simaski endala iluhlaza ngokwesiko kodwa manje isitholakala ngemibala eminingi.
Inqubo ye-solder mask
Inqubo yemaski ye-solder ihlanganisa izinyathelo ezimbalwa.
Ngemuva kwesinyathelo sokuhlanza ngaphambili, lapho amabhodi wesifunda aphrintiwe ahlanjululwa khona futhi indawo yethusi iphelile ngomshini noma ngamakhemikhali, imaski ye-solder isetshenziswa.
Kunezinhlelo zokusebenza ezimbalwa ezifana nokufakwa kwamakhethini, ukuphrinta isikrini noma ukugcotshwa kwesifutho okutholakalayo.
Ngemuva kokuthi ama-PCB embozwe imaski ye-solder, i-solvent idinga ukukhanyisa esinyathelweni sokumisa i-tack.
Isinyathelo esilandelayo ekulandeleni ukuchayeka.Ukuze uhlele imaski ye-solder, kusetshenziswa ubuciko.Amabhodi avezwa ngomthombo wokukhanya ojwayelekile ongu-360 nm.
Izindawo eziveziwe zizokhula zibe polymer kuyilapho izindawo ezimboziwe zizohlala ziyi-monomer.
Enqubweni yokuthuthukisa izindawo eziveziwe ziyamelana, futhi izindawo ezingaveziwe (i-monomer) zizokhukhulwa.
Ukwelashwa kokugcina kwenziwa kuhhavini ye-batch noma umhubhe.Ngemva kokwelashwa kokugcina, kungase kudingeke ukwelashwa okwengeziwe kwe-UV ukuze kukhuliswe izakhiwo zemishini nezamakhemikhali zemaski ye-solder.
Umsebenzi oyinhloko we-solder mask:
Ngakho-ke yini umsebenzi we-Solder Mask?
Khetha okubili phakathi kohlu:
1. Ukuvikelwa ekufakweni kwe-oxidation.
2. Ukuvikelwa ekushiseni.
3. Ukuvikelwa ebhulohweni le-solder ngengozi.
4. Ukuvikelwa ekukhishweni kwe-electrostatic.
5. Ukuvikelwa ekukhishweni kwe-hyper yamanje.
6. Ukuvikelwa othulini.
Ngaphandle kwemisebenzi esemqoka engenhla, kukhona nezinye izinhlelo zokusebenza.Uma kusenemibuzo eyengeziwe mayelana ne-solder mask, Sicela uthintane nochwepheshe ku-PHILIFAST.
