Ponena za chitukuko chamakono cha PCB ukadaulo, ndili ndi malingaliro awa:

1. Kupititsa patsogolo njira yaukadaulo yolumikizirana kwambiri (HDI)

Monga HDI ikuphatikiza ukadaulo wapamwamba kwambiri wa PCB yamakono, imabweretsa waya wabwino ndi kabowo kakang’ono ku PCB. Pakati pa HDI multilayer board application terminal electronic products-mafoni a m’manja (mafoni a m’manja) ndi chitsanzo chaukadaulo waukadaulo wa HDI. M’mafoni am’manja, ma PCB motherboard micro-waya (50μm～75μm/50μm～75μm, waya m’lifupi / katalikirana) akhala otchuka. Komanso, wosanjikiza conductive ndi bolodi makulidwe ndi woonda; mawonekedwe a conductive amayengedwa, omwe amabweretsa zida zamagetsi zamagetsi zamagetsi zowoneka bwino komanso zowoneka bwino.

Pazaka makumi awiri zapitazi, HDI yakhala ikulimbikitsa chitukuko cha mafoni a m’manja, zomwe zinachititsa kuti pakhale chitukuko cha ndondomeko ya chidziwitso ndi kulamulira pafupipafupi kwa LSI ndi CSP chips (maphukusi), ndi magawo a template kuti anyamule. Imalimbikitsanso chitukuko cha PCBs. Chifukwa chake, iyenera kukulirakulira mumsewu wa HDI.

2. chigawo embedding luso ali wamphamvu nyonga

Kupanga zida za semiconductor (zomwe zimatchedwa zigawo zogwira ntchito), zida zamagetsi (zotchedwa passive components) kapena zigawo zamkati za PCB. “Component ophatikizidwa PCB” wayamba kupanga ambiri. Ukadaulo wophatikizidwa ndi gawo la PCB logwira ntchito lophatikizika. Zosintha zazikulu, koma njira zopangira zoyeserera ziyenera kuthetsedwa kuti zitheke. Ukadaulo wopanga, mawonekedwe owunikira, komanso kutsimikizika kodalirika ndizomwe zimafunikira kwambiri.

Tiyenera kuonjezera ndalama zazinthu zamakina kuphatikiza mapangidwe, zida, kuyesa, ndi kuyerekezera kuti tikhalebe amphamvu.

Chachitatu, chitukuko cha zipangizo PCB ayenera bwino

Kaya ndi PCB yolimba kapena zida zosinthika za PCB, ndi kudalirana kwa zinthu zamagetsi zopanda lead, zidazi ziyenera kupangidwa kuti zisatenthe kutentha, kotero mtundu watsopano wa Tg wapamwamba, wowonjezera kutentha kwapang’onopang’ono, wokhazikika pang’ono wa dielectric, ndi dielectric yabwino kwambiri. kutaya tangent kumawonekerabe.

Chachinayi, ziyembekezo za optoelectronic PCBs ndi zazikulu

Amagwiritsa ntchito mawonekedwe a kuwala ndi mawonekedwe ozungulira kuti atumize zizindikiro. Chinsinsi cha teknoloji yatsopanoyi ndi kupanga mawonekedwe a optical path (optical waveguide layer). Ndi organic polima kuti amapangidwa ndi njira monga lithography, laser ablation, ndi reactive ion etching. Pakalipano, lusoli lakhala likugwiritsidwa ntchito ku Japan ndi United States.

5. Njira yopangira zinthu iyenera kusinthidwa ndi zipangizo zamakono ziyenera kuyambitsidwa

1. Njira Yopangira

Kupanga kwa HDI kwakhwima ndipo kumakonda kukhala kwangwiro. Ndi chitukuko cha teknoloji ya PCB, ngakhale kuti njira zogwiritsira ntchito zochepetsera zomwe zimagwiritsidwa ntchito nthawi zambiri zimagwirabe ntchito, njira zotsika mtengo monga njira zowonjezera ndi zowonjezera zowonjezera zayamba kuonekera.

Kugwiritsa ntchito nanotechnology kupanga mabowo zitsulo ndi nthawi imodzi kupanga ma PCB conductive mapatani, njira yatsopano yopangira ma board osinthika.

Kudalirika kwambiri, njira yosindikizira yapamwamba kwambiri, inkjet PCB ndondomeko.

2. Zida zamakono

Kupanga mawaya abwino, ma photomasks atsopano apamwamba kwambiri ndi zida zowonetsera, ndi zida zowunikira mwachindunji za laser.

Zida zomangira yunifolomu.

Chigawo chopanga chophatikizidwa (chinthu chogwira ntchito) chopangira ndikuyika zida ndi zida.
