Semuenzaniso, ndiro yerata: yepamusoro muganhu=X+Y-6MIL yakaderera muganho=XY-4MIL
Verenga iyo yepakati = (yepamusoro muganho + yakaderera muganho)/2
≈A+Nzvimbo yechikamu chechipiri chefoil yemhangura%*E+nzvimbo yechitatu yefoil yemhangura%*E+B*2+F*2
Iyo yemukati yekucheka zvinhu zveyakajairika mana-layer board idiki 0.4mm pane yakapedzwa bhodhi, uchishandisa imwechete 2116 PP sheet kudzvanya. Kune yakakosha yemukati yakatsetseka ukobvu hwemhangura uye yekunze layer yemhangura ukobvu inopfuura 1OZ, ukobvu hwemhangura hunofanirwa kutariswa pakusarudza yemukati layer zvinhu.
2.Karukureta kushivirira kushivirira:
Yepamusoro muganho = Yakapedzwa bhodhi ukobvu + Yakapedzwa pa-line kushivirira kukosha - [Kuisa mhangura ukobvu, girinhi mafuta hunhu ukobvu
(Conventional 0.1MM)]-Iyo nedzidziso yakaverengerwa ukobvu mushure mekudzvanya
Yakaderera muganho = yapera bhodhi ukobvu-yapedzwa chigadzirwa kunze-mutsara kushivirira kukosha- [Electroplating mhangura ukobvu, girinhi mafuta hunhu ukobvu
(Regular 0.1MM)]-Iyo theoretically yakaverengerwa ukobvu mushure mekudzvanya
3.Kakawanda marudzi emapp mapepa
Kazhinji, usashandise mapepa maviri ePP ane yakakwirira resin zvirimo pamwechete. Kana iyo yemukati layer yemhangura yakanyanya kudiki, ndapota shandisa PP mapepa ane yakakwira resin yemukati. 1080 PP mapepa ane yakanyanya kusimba uye yakaderera resin yemukati. Usadzvanya mapepa mamwe zvakanyanya sezvinobvira. Mashizha maviri chete e2116 uye 7630 PP mapepa anogona kudzvanywa mumahwendefa akakora emhangura pamusoro pe2OZ. Iyo layer haigone kudzvanywa nepepa rimwechete rePP. 7628 PP pepa rinogona kudzvanywa nepepa rimwechete, 2 mapepa, matatu mapepa, kana anosvika mana mapepa.
Tsananguro ye theoretical ukobvu kuverenga kwe multilayer PCB board mushure mekudzvanya
Hukobvu mushure mePP lamination = 100% yakasara yemhangura yakakora ukobvu-yemukati mhangura ukobvu *(1-Kusara kwemhangura chiyero%)
Sezita, multilayer PCBs musanganiswa weakasiyana multilayer maseketi. Nhamba ye-single-sided and double-sided PCBs inosanganiswa uye inoparadzaniswa ne insulating material (yakadai se dielectric) kuti iite multilayer PCB yeiyi yakaoma dhizaini. Inowedzera nhamba yezvikamu uye inowedzera nzvimbo inowanikwa kune wiring.
Nhamba ye conductive layers pakati pe insulating materials inenge 3, uye kusvika ku 100. Isu tinowanzova ne 4 kusvika ku 12 layers, semuenzaniso, ma smartphones anonyanya 12 layers. Nhamba huru yezvikamu zvinoita kuti zvive zvakakodzera kuoma kwekushandiswa. Vagadziri vanosarudza kunyange maseru nekuti laminating nhamba isinganzwisisike yezvikamu zvingaite kuti dunhu rive rakaoma uye rakaoma.
Multilayer PCBs anowanzo kuomarara nekuti zvakaoma kuti PCBS inoshanduka isvike akawanda akaturikidzana. Rigid multilayer PCBs dzinoda kudhiraivha kuti dzibatanidze zvidimbu zvakasiyana. Zvakajairika kuburikidza-makomba anogona kutambisa nzvimbo, saka pachinzvimbo kuvigwa kana bofu kuburikidza-maburi anoshandiswa, ayo anongopinda anodiwa akaturikidzana. Zvikamu zvakasiyana zvinogona kuiswa mundege dzakasiyana, senge ndege yepasi, ndege yemagetsi, uye ndege yemasaini.
Kana iwe uchida kuvaka PCB, pane zvakasiyana-siyana zvekusarudza kubva, zvakadai semakeramiki anokosha, epoxy plexiglass. Iyo resin uye binder zvinhu zvino batanidza zvikamu uye zvidimbu zvakasiyana pamwechete. Relaminating, inoitwa pakupisa kwakanyanya uye kumanikidzwa, inobvisa chero mweya wakavharirwa pakati pematanho uye inobatsira kunyungudutsa akasiyana prepreg layer uye core layer.
