Ukadaulo wosiyanasiyana wopanga waukadaulo wa HDI PCB

Chiyambi:

Ukadaulo wa High-density interconnect (HDI) ma PCB asintha makampani opanga zamagetsi popangitsa kuti pakhale magwiridwe antchito ambiri pazida zing'onozing'ono, zopepuka. Ma PCB apamwambawa adapangidwa kuti apititse patsogolo mawonekedwe azizindikiro, kuchepetsa kusokoneza kwaphokoso komanso kulimbikitsa miniaturization. Mu positi iyi yabulogu, tiwona njira zosiyanasiyana zopangira zomwe zimagwiritsidwa ntchito popanga ma PCB aukadaulo wa HDI. Pomvetsetsa njira zovutazi, mudzapeza chidziwitso cha dziko lovuta la makina osindikizira osindikizira komanso momwe zimathandizira kupititsa patsogolo luso lamakono.

1. Laser Direct Imaging (LDI) :

Laser Direct Imaging (LDI) ndiukadaulo wodziwika bwino womwe umagwiritsidwa ntchito popanga ma PCB okhala ndi ukadaulo wa HDI. Imalowetsa m'malo mwa njira zachikhalidwe za Photolithography ndipo imapereka luso latsatanetsatane. LDI imagwiritsa ntchito laser kuti iwonetse mwachindunji photoresist popanda kufunikira kwa chigoba kapena stencil. Izi zimathandiza opanga kuti akwaniritse kukula kwazinthu zing'onozing'ono, kachulukidwe kafupipafupi, komanso kulembetsa bwino kwambiri.

Kuphatikiza apo, LDI imalola kupanga mabwalo abwino, kuchepetsa danga pakati pa mayendedwe ndikukulitsa kukhulupirika kwa ma siginecha. Imathandiziranso ma microvias olondola kwambiri, omwe ndi ofunikira kwambiri pama PCB aukadaulo a HDI. Ma Microvias amagwiritsidwa ntchito kulumikiza zigawo zosiyanasiyana za PCB, motero amakulitsa kachulukidwe kanjira ndikuwongolera magwiridwe antchito.

2. Zomangamanga Zotsatizana (SBU):

Sequential Assembly (SBU) ndiukadaulo wina wofunikira wopanga womwe umagwiritsidwa ntchito kwambiri popanga PCB paukadaulo wa HDI. SBU imakhudzanso mapangidwe a PCB-wosanjikiza, kulola mawerengedwe apamwamba ndi miyeso yaying'ono. Tekinolojeyi imagwiritsa ntchito zigawo zingapo zoonda, chilichonse chimakhala ndi zolumikizira zake komanso ma vias.

Ma SBU amathandizira kuphatikiza mabwalo ovuta kukhala ang'onoang'ono, kuwapanga kukhala abwino pazida zamagetsi zamagetsi. Njirayi imaphatikizapo kugwiritsa ntchito insulating dielectric layer kenako kupanga madera ofunikira kudzera munjira monga zowonjezera zowonjezera, etching ndi kubowola. Vias ndiye amapangidwa ndi kubowola laser, kubowola makina kapena kugwiritsa ntchito njira ya plasma.

Panthawi ya SBU, gulu lopanga liyenera kukhalabe ndi kuwongolera kokhazikika kuti zitsimikizire kulumikizana koyenera ndikulembetsa magawo angapo. Kubowola kwa laser nthawi zambiri kumagwiritsidwa ntchito popanga ma microvias ang'onoang'ono, potero kumawonjezera kudalirika komanso magwiridwe antchito aukadaulo wa HDI PCBs.

3. Tekinoloje yopangira ma Hybrid:

Pomwe ukadaulo ukupitilirabe kusinthika, ukadaulo wopanga wosakanizidwa wakhala njira yabwino kwambiri yama PCB aukadaulo a HDI. Ukadaulo uwu umaphatikiza njira zachikhalidwe komanso zapamwamba kuti zithandizire kusinthasintha, kuwongolera magwiridwe antchito komanso kukhathamiritsa kagwiritsidwe ntchito kazinthu.

Njira imodzi yosakanizidwa ndikuphatikiza matekinoloje a LDI ndi SBU kuti apange njira zopangira zida zapamwamba kwambiri. LDI imagwiritsidwa ntchito popanga mawonekedwe olondola komanso mabwalo abwino, pomwe SBU imapereka zomanga zomangira ndi kusanjikiza koyenera kwa mabwalo ovuta. Kuphatikiza uku kumatsimikizira kupanga bwino kwa ma PCB apamwamba kwambiri, ochita bwino kwambiri.

Kuphatikiza apo, kuphatikiza kwaukadaulo wosindikiza wa 3D ndi njira zopangira zachikhalidwe za PCB kumathandizira kupanga mawonekedwe ovuta komanso makoma mkati mwa ma PCB aukadaulo a HDI. Izi zimathandiza kuti kutentha kwabwino, kuchepetsa kulemera ndi kukhazikika kwa makina.

Pomaliza:

Ukadaulo wopangira womwe umagwiritsidwa ntchito mu HDI Technology PCB umakhala ndi gawo lofunikira pakuyendetsa zatsopano ndikupanga zida zapamwamba zamagetsi. Kuyerekeza kwachindunji kwa laser, kupanga motsatizana komanso matekinoloje opanga ma hybrid amapereka maubwino apadera omwe amakankhira malire a miniaturization, kukhulupirika kwa ma sign ndi kachulukidwe kadera. Ndi kupita patsogolo kosalekeza kwaukadaulo, kutukuka kwa matekinoloje atsopano opangira zinthu kudzapititsa patsogolo luso laukadaulo wa HDI PCB ndikulimbikitsa kupita patsogolo kwamakampani opanga zamagetsi.
