Amazinga Wokuhlola Ibhodi Lesifunda
1. Ububanzi bufanele ukuhlolwa okungenayo kwamabhodi wesekethe we-HDI weselula.
2. Uhlelo lwamasampula luzohlolwa ngokuya nge-GB2828.1-2003, izinga lokuhlola jikelele II.
3. Ukuhlola kusekelwe emibhalweni yobuchwepheshe yezinto ezingavuthiwe namasampula okuhlola.
4. Izinga lekhwalithi elifanelekayo lisekelwe kunani le-AQL: Ikilasi A = 0.01, Ikilasi B = 0.65, Ikilasi C = 2.5.
5. Amathuluzi okuhlola nezinto zokusebenza: i-plug gauge, i-vernier caliper, i-oven reflow, i-dynamometer, ingilazi yokukhulisa, i-multimeter yedijithali, izinga lokushisa elingaguquki kanye nebhokisi lomswakamo, isihloli sempilo esingukhiye, isihloli sogqinsi esifakwe ngegolide, imabula eyisicaba noma ingilazi, umhloli wokumelana nokushisa , izinga lokushisa elivamile le-ferrochrome.
6. Ukuhlelwa kokukhubazeka: inombolo ye-serial inombolo Into yokuhlola Incazelo yesici Iphakheji yangaphandle imanzi, izinto ezisetshenziswayo zibekwe endaweni engalungile Isigaba sesici CB Amazwana 1 Alikho ilebula ngaphakathi noma ngaphandle kwephakeji, ilebula engalungile, ukuwisa amanzi ngaphakathi, akukho buhlalu obuvimbela umswakama, abukho ikhadi lokuswakama. , izinto ezixubile, akukho Iphakheji ye-vacuum.
1 Umbiko wokuthumela awunikeziwe.Umbiko wokuthunyelwa kwefekthri
2. Izinto zokuhlola ezisembikweni wokuthunyelwa komkhiqizi azihambisani futhi ziphelele ngokuya ngezidingo zethu ezijwayelekile zokuhlola, idatha yokuhlola ayihlangabezani nezidingo ezijwayelekile, umbiko awunakugunyazwa komphathi wekhwalithi noma abasebenzi bezinga eliphezulu, kanye nombiko. okuqukethwe kungamanga, njll. Uma izimfuneko ezingenhla zingahlangatshezwana nazo.Izinto zokuhlola inombolo ye-serial B Incazelo yesici esivamile Izinto ezingenayo zihlukile kumkhiqizi wesampula, inombolo yepuleti ehlukile, ipuleti elihlukile (okuhlanganisa nokungahlonzwa kwepuleti), akukho umjikelezo wokukhiqiza, futhi alikho izinga lasefekthri.Akumele kube khona imiphetho ecijile eduze kwe-PCB ukuze kuthinte ukuhlanganiswa futhi kulimaze isisebenzisi.Ama-pores nama-pores ambalwa Ama-pores amakhulu namancane (ngokuvumelana nezidingo zemidwebo yokuklama) Kukhona ithusi elisele emgodini we-NPTH, futhi kukhona i-oxidation emgodini.) indawo yokungena eqediwe: uma yeqa lezi zidingo ezingezansi
3 Ukubhoboza izimbobo eziyindilinga: NPTH: +/-2mil (+/-0.05mm);I-NPTH: imbobo yethusi engacwi B;I-PTH: imbobo yethusi ezikayo PTH: +/-3mil (+/-0.075mm) 2,
