The warpage ya gulu la zigawo zinayi akhoza kulamulidwa pansipa 0,7% , koma kukula kwa bolodi la zigawo zitatu ndi lalikulu. Panthawi imeneyo, tsamba la nkhondo lidzapitirira muyeso uwu, zomwe zidzakhudza kudalirika kwa msonkhano wa SMT ndi mankhwala onse. Choncho, mlengi sayenera kupanga gulu losanjikiza losawerengeka. Ngakhale gawo losawerengeka litakhala lofunikira, lidzapangidwa ngati wosanjikiza wabodza wowerengeka. Ndiko kupanga magawo asanu kukhala 6 ndi 7 mu magawo 8.
Yankho: Kukhuthala kwa wosanjikiza wamkati
E: Kukhuthala kwa zojambula zamkuwa zamkati
X: Kumaliza bolodi makulidwe
B: Makulidwe a pepala la PP
F: Kukhuthala kwa zojambula zamkuwa zakunja
Y: Anamaliza kulolerana kwa PCB
1.Chezerani malire apamwamba ndi apansi akukanikiza:
Nthawi zambiri mbale ya malata: malire apamwamba -6MIL, malire otsika-4MIL
Mbale yagolide: malire apamwamba -5MIL, malire otsika -3MIL
Mwachitsanzo, mbale ya malata: malire apamwamba=X+Y-6MIL otsika=XY-4MIL
Werengerani wapakati = (malire apamwamba + malire otsika)/2
≈A+gawo lachiwiri la zojambulazo zamkuwa%*E+gawo lachitatu la zojambulazo zamkuwa%*E+B*2+F*2
Zida zamkati zodulira zomwe zili pamwambazi ndizocheperako 0.4mm kuposa bolodi yomalizidwa, pogwiritsa ntchito pepala limodzi la 2116 PP kukanikiza. Mwapadera mkati wosanjikiza mkuwa makulidwe ndi kunja wosanjikiza mkuwa makulidwe kuti kuposa 1OZ, makulidwe mkuwa ayenera kuganiziridwa posankha mkati wosanjikiza zakuthupi.
2.Yerekezerani kulolerana kwakanthawi:
Malire apamwamba = Kutsirizika kwa bolodi + Kutsirizika pamtengo wololera pa intaneti - Kupaka makulidwe amkuwa, makulidwe amafuta obiriwira
(Wovomerezeka 0.1MM)]-Kuchuluka kwake komwe kumawerengedwera pambuyo pa kukanikiza
M'munsi malire = kumalizidwa kwa bolodi makulidwe-kumalizidwa kwa mtengo wololera pa intaneti - Kuchuluka kwa mkuwa wa Electroplating, makulidwe amafuta obiriwira
(Wanthawi zonse 0.1MM)]-Kunenepa kowerengeredwa mongoyerekeza pambuyo kukanikiza
3.Kawirikawiri mitundu ya pp mapepala
Nthawi zambiri, musagwiritse ntchito mapepala awiri a PP okhala ndi utomoni wambiri pamodzi. Ngati wosanjikiza wamkati wamkuwa ndi wocheperako, chonde gwiritsani ntchito mapepala a PP okhala ndi utomoni wambiri. Mapepala a 1080 PP ali ndi kachulukidwe kwambiri komanso otsika utomoni. Osasindikiza mapepala amodzi momwe mungathere. Mapepala a 2 okha a 2116 ndi 7630 PP mapepala omwe angathe kukanikizidwa mu mbale zamkuwa zakuda pamwamba pa 2OZ. Chosanjikiza sichingapanikizidwe ndi pepala limodzi la PP. 7628 PP pepala akhoza mbamuikha ndi pepala limodzi, 2 mapepala, 3 mapepala, kapena mpaka 4 mapepala.
Kufotokozera za kuwerengetsera makulidwe a multilayer PCB board mutatha kukanikiza
Makulidwe pambuyo PP lamination = 100% yotsalira mkuwa lamination makulidwe-mkati mkuwa makulidwe *(1-Kutsala mlingo wamkuwa%)
Monga dzina, ma PCB ambiri ndi kuphatikiza kwa mabwalo osiyanasiyana osiyanasiyana. Ma PCB angapo a mbali imodzi ndi awiri amaphatikizidwa ndikulekanitsidwa ndi zinthu zotetezera (monga dielectric) kuti apange multilayer PCB ya mapangidwe ovutawa. Imawonjezera kuchuluka kwa zigawo ndikuwonjezera malo omwe akupezeka kuti azitha waya.
Chiwerengero cha zigawo zochititsa chidwi pakati pa zipangizo zotetezera ndi osachepera 3, mpaka 100. Nthawi zambiri timakhala ndi zigawo 4 mpaka 12, mwachitsanzo, mafoni a m'manja nthawi zambiri amakhala 12. Kuchuluka kwa zigawo kumawapangitsa kukhala oyenera ku zovuta za ntchito. Opanga amasankha ngakhale zigawo chifukwa kuyika nambala yosamvetseka kungapangitse kuti dera likhale lovuta komanso lovuta.
Ma PCB a Multilayer nthawi zambiri amakhala okhwima chifukwa ndizovuta kuti ma PCBS osinthika afikire zigawo zingapo. Ma PCB olimba a multilayer amafunika kubowoledwa kuti alumikizane ndi magawo osiyanasiyana. Wamba kudzera-mabowo akhoza kuwononga danga, kotero m'malo kukwiriridwa kapena khungu kudzera-mabowo ntchito, amene amalowa mu zigawo zofunika. Magawo osiyanasiyana amatha kugawidwa m'magulu osiyanasiyana, monga ndege yapansi, ndege yamagetsi, ndi ndege yama sign.
Ngati mukufuna kupanga PCB, pali zinthu zosiyanasiyana zomwe mungasankhe, monga zoumba zapadera, epoxy plexiglass. Zida za resin ndi binder zimagwirizanitsa zigawozo ndi zigawo zosiyanasiyana pamodzi. Relaminating, yochitidwa pa kutentha kwambiri ndi kupanikizika, imachotsa mpweya uliwonse pakati pa zigawozo ndikuthandizira kusungunula zigawo zosiyana za prepreg ndi zigawo zapakati.
