Njira Yopangira HDI Technology PCBs: Kuwonetsetsa Kuchita ndi Kudalirika

M'nthawi yamasiku ano ya chitukuko chofulumira chaukadaulo, zida zamagetsi zakhala gawo lofunikira pa moyo wathu watsiku ndi tsiku. Kuyambira pa mafoni mpaka pazida zamankhwala, ma board osindikizira (PCBs) amagwira ntchito yofunika kwambiri pakuwongolera zida izi. Ma PCB aukadaulo a High Density Interconnect (HDI) akhala akusintha masewerawa, opereka kachulukidwe kapamwamba, magwiridwe antchito komanso kudalirika kowonjezereka.Koma kodi mudadabwa kuti ma PCB aukadaulo a HDI amapangidwa bwanji? M'nkhaniyi, tiona zovuta za kupanga ndi kulongosola njira zomwe zikukhudzidwa.

1. Chiyambi chachidule chaukadaulo wa HDI PCB:

Ma PCB aukadaulo a HDI ndi otchuka chifukwa cha kuthekera kwawo kokhala ndi zigawo zambiri pamapangidwe ophatikizika, kuchepetsa kukula konse kwa zida zamagetsi.Ma board awa amakhala ndi zigawo zingapo, ma vias ang'onoang'ono, ndi mizere yocheperako pakuchulukirachulukira kwamayendedwe. Kuphatikiza apo, amapereka magwiridwe antchito amagetsi, kuwongolera kwa impedance, ndi kukhulupirika kwa ma sign, kuwapangitsa kukhala oyenera kugwiritsa ntchito kuthamanga kwambiri komanso kuthamanga kwambiri.

2. Kamangidwe kake:

Ulendo wopanga HDI Technology PCB umayambira pakupanga.Mainjiniya aluso ndi opanga amagwirira ntchito limodzi kukhathamiritsa masanjidwe ozungulira ndikuwonetsetsa kuti malamulo ndi zopinga zikukwaniritsidwa. Gwiritsani ntchito zida zapamwamba zamapulogalamu kuti mupange mapangidwe olondola, kufotokozera masanjidwe osanjikiza, kakhazikitsidwe kagawo ndi njira. Masanjidwewo amaganiziranso zinthu monga kukhulupirika kwa chizindikiro, kuwongolera kutentha, komanso kukhazikika kwamakina.

3. Kubowola laser:

Chimodzi mwamasitepe ofunikira pakupanga ukadaulo wa HDI PCB ndikubowola laser.Ukadaulo wa laser ukhoza kupanga ma vias ang'onoang'ono, olondola kwambiri, omwe ndi ofunikira kuti akwaniritse kachulukidwe kakang'ono. Makina obowola laser amagwiritsa ntchito kuwala kwamphamvu kwambiri kuti achotse zinthu pagawo laling'ono ndikupanga mabowo ang'onoang'ono. Vias izi ndiye metallized kulenga kugwirizana magetsi pakati pa zigawo zosiyanasiyana.

4. Zovala zamkuwa zopanda magetsi:

Kuonetsetsa kuti magetsi amalumikizana bwino pakati pa zigawo, electroless copper deposition imagwiritsidwa ntchito.Pochita izi, makoma a dzenje lobowola amakutidwa ndi mkuwa wowonda kwambiri wa conductive ndi kumizidwa ndi mankhwala. Chosanjikiza chamkuwachi chimagwira ntchito ngati mbewu yotsatizana ndi electroplating, kupititsa patsogolo kumamatira komanso kutulutsa kwa mkuwa.

5. Lamination ndi kukanikiza:

Kupanga kwa HDI Technology PCB kumaphatikizapo maulendo angapo ozungulira ndi kukanikiza komwe zigawo zosiyanasiyana za gulu lozungulira zimayikidwa ndikugwirizanitsidwa pamodzi.Kuthamanga kwakukulu ndi kutentha kumagwiritsidwa ntchito kuti zitsimikizidwe kuti zigwirizane bwino ndikuchotsa matumba a mpweya kapena voids. Njirayi imaphatikizapo kugwiritsa ntchito zida zapadera za lamination kuti mukwaniritse makulidwe omwe mukufuna komanso kukhazikika kwamakina.

6. Kupaka mkuwa:

Copper plating imagwira ntchito yofunika kwambiri muukadaulo wa HDI PCBs popeza imakhazikitsa makonzedwe amagetsi ofunikira.Njirayi imaphatikizapo kuviika bolodi lonse muzitsulo zopangira mkuwa ndikudutsa mphamvu yamagetsi. Kupyolera mu njira ya electroplating, mkuwa umayikidwa pamwamba pa bolodi la dera, kupanga mabwalo, kufufuza ndi mawonekedwe apamwamba.

7. Chithandizo chapamwamba:

Kuchiza pamwamba ndi gawo lofunika kwambiri pakupanga kuti ateteze mabwalo ndikuwonetsetsa kudalirika kwanthawi yayitali.Ukadaulo wodziwika bwino waukadaulo wa HDI wa PCB umaphatikizapo siliva womiza, golide womiza, zosungirako zosungiramo zinthu (OSP), ndi faifi yamagetsi yopanda ma electroless/immersion gold (ENIG). Matekinoloje awa amapereka chitetezo chomwe chimalepheretsa makutidwe ndi okosijeni, kumapangitsa kusungunuka, komanso kumathandizira kusonkhana.

8. Kuyesa ndi Kuwongolera Ubwino:

Kuyesa mozama ndi kuwongolera khalidwe kumafunika ma PCB aukadaulo a HDI asanasonkhanitsidwe kukhala zida zamagetsi.Automated optical inspection (AOI) ndi magetsi (E-test) nthawi zambiri amachitidwa kuti azindikire ndi kukonza zolakwika zilizonse kapena vuto lamagetsi pagawo. Mayeserowa amatsimikizira kuti chomaliza chimakwaniritsa zofunikira ndipo chimagwira ntchito modalirika.

Pomaliza:

Ma PCB a HDI Technology asintha makampani opanga zamagetsi, kuthandizira kupanga zida zazing'ono, zopepuka komanso zamphamvu kwambiri.Kumvetsetsa zovuta zopangira kuseri kwa matabwawa zikuwonetsa kuchuluka kwaukadaulo komanso ukadaulo wofunikira kuti apange ma PCB apamwamba kwambiri a HDI. Kuchokera pakupanga koyambirira kudzera pakubowola, plating ndi kukonza pamwamba, sitepe iliyonse ndiyofunikira kuti zitsimikizire kuti zikuyenda bwino komanso zodalirika. Pogwiritsa ntchito njira zotsogola zopangira zinthu komanso kutsatira mfundo zokhwimitsa zinthu, opanga amatha kukwaniritsa zomwe zimakonda kusintha pamsika wamagetsi ndikutsegulira njira zotsogola.
