Izici eziyinhloko ezithinta izinga lokugcwalisa lokunamathisela kwe-solder yijubane lokuphrinta, i-angle ye-squeegee, ingcindezi ye-squeegee ngisho nenani le-solder paste elinikeziwe.Ngamagama alula, lapho ijubane lishesha futhi liba lincane i-engeli, kulapho amandla ehlela phansi e-solder paste futhi kulula ukuyigcwalisa, kodwa maningi amathuba okuthi unamathisele uzompintsheka endaweni ye-whetstone ye-stencil. noma ingozi yokugcwaliswa okungaphelele.
Izici eziyinhloko ezithinta ukuphrinta kwe-solder paste isilinganiso sendawo ye-stencil, ukuqina kodonga lwembobo ye-stencil kanye nokuma kwembobo.
1. Isilinganiso sendawo
Isilinganiso sendawo isilinganiso sendawo yewindi le-stencil endaweni yodonga lwembobo yefasitela.
2. Izinga lokudlulisa
Izinga lokudlulisela libhekisela esilinganisweni sokunamathisela kwe-solder efakwe kuphedi efasiteleni le-stencil ngesikhathi sokuphrinta, esivezwa njengesilinganiso senani langempela lokunamathisela okudlulisiwe kuvolumu yewindi le-stencil.
3. Umthelela wesilinganiso sendawo esilinganisweni sokudlulisa
Isilinganiso sendawo siyisici esibalulekile esithinta ukudluliswa kobunjiniyela be-solder paste ngokuvamile kudinga isilinganiso sendawo esikhulu kuno-0.66, kulesi simo singathola ngaphezu kuka-70% wezinga lokudlulisa.
4. Isilinganiso sendawo ezidingweni zokuklama
Isilinganiso sendawo yezidingo zedizayini ye-stencil, ethinta kakhulu izingxenye zephimbo elihle.Ukuze uqinisekise izidingo zesilinganiso sendawo yefasitela elincane le-stencil, ubukhulu be-stencil kufanele buhlangabezane nezidingo zesilinganiso sendawo.Lokhu kudinga izingxenye ezengeziwe zenani le-solder unamathisele, kuyadingeka ukwandisa inani le-solder unamathisele ngokwandisa indawo yefasitela le-stencil Lokhu kudinga ukuguqulwa kwesikhala esizungeze i-pad, okucatshangelwa kakhulu ekuklanyeni iphimbo lengxenye.
Iphrinta ye-stencil ye-NeoDen ND2 ezenzakalelayo
1. Indlela emine yomthombo wokukhanya iyalungiseka, amandla okukhanya ayalungiseka, ukukhanya kuyafana, futhi ukutholwa kwesithombe kuphelele kakhulu;Ukuhlonza okuhle (okuhlanganisa namaphoyinti amamaki angalingani), kulungele ukuthayela, ukucwecwa ngethusi, ukucwecwa kwegolide, ukufuthwa ngothayela, i-FPC nokunye. izinhlobo ze-PCB ezinemibala ehlukene.
2. Isilungiselelo esihlakaniphile esihlelekayo, amamotho amabili aqondile ashayelwa i-squeegee, isistimu yokulawula ingcindezi eyakhelwe ngaphakathi.
3. Uhlelo olusha lokusula luqinisekisa ukuthintana okugcwele ne-stencil;izindlela ezintathu zokuhlanza ezomile, ezimanzi kanye ne-vacuum, kanye nenhlanganisela yamahhala ingakhethwa;ipuleti lokusula lerabha elithambile elingagqoki, ukuhlanzwa kahle, ukuqaqa okulula, nobude bephepha lokusula.
4. I-scraper Y axis yamukela i-servo motor drive nge-screw drive, ukuze kuthuthukiswe izinga lokunemba, ukuzinza kokusebenza kanye nokwelula impilo yesevisi, ukuhlinzeka amakhasimende ngesikhulumi esihle sokulawula ukuphrinta.
