Ma board a HDI (High Density Interconnect) akhala osankhika pamitundu yamakono yamagetsi. Amapereka maubwino ambiri kuposa ma board osindikizira achikhalidwe (PCBs), monga kuchulukitsitsa kozungulira, mawonekedwe ang'onoang'ono, komanso kukhulupirika kwa ma siginecha. Komabe,makonzedwe apadera a matabwa a HDI amafunikira kukonzekera mosamala ndi kuchitidwa kuti zitsimikizidwe kuti zikugwira ntchito bwino komanso kudalirika. Apa tiwona zinthu zofunika kuziganizira popanga HDI board.
1. Miniaturization ndi kamangidwe kagawo:
Chimodzi mwazifukwa zazikulu zogwiritsira ntchito matabwa a HDI ndi kuthekera kwawo kokhala ndi zigawo zambiri pamapazi ang'onoang'ono. Monga wopanga, muyenera kuganizira za miniaturization ndikukonzekera mosamala masanjidwe a zigawozo. Kuyika kwazinthu kumagwira ntchito yofunika kwambiri pakukwaniritsa kapangidwe kameneka popanda kusokoneza kukhulupirika kwa chizindikiro.
Kuti muwongolere kachipangizo kakang'ono, lingalirani zogwiritsa ntchito zing'onozing'ono, zophatikizika kwambiri. Kuphatikiza apo, kugwiritsa ntchito ukadaulo wapamwamba kwambiri (SMT) kumathandizira kuyika bwino kwa gawo, kuchepetsa kukula kwa bolodi. Komabe, onetsetsani kuti mwasanthula zofunikira za kutentha ndikuwonetsetsa kuti pali njira zoziziritsira zokwanira, makamaka pazigawo zamphamvu zamphamvu.
2. Kukhulupirika kwa ma Signal ndi kutumiza:
Ma board a HDI amathandizira ma frequency apamwamba komanso kuthamanga kwambiri, chifukwa chake kukhulupirika kwa chizindikiro kumakhala kofunikira. Kuchepetsa kutayika kwa chizindikiro ndi kusokoneza ndikofunikira kuti musunge kukhulupirika kwa chizindikiro. Nazi zina zofunika kuzikumbukira:
a. Kuwongolera kwa Impedans:Imawonetsetsa kugwirizana koyenera kwa impedance pa bolodi. Izi zitha kutheka posankha mosamalitsa m'lifupi mwake, malo ndi zinthu za dielectric. Kutsatira miyezo yoyendetsedwa ndi impedance yokhudzana ndi pulogalamu yanu ndikofunikira kuti muchepetse kuyimitsidwa kwa ma sign.
b. Crosstalk yoyendetsedwa:Mapangidwe amphamvu kwambiri nthawi zambiri amapangitsa kuti pakhale mipata yotalikirana pama board a HDI, zomwe zimatsogolera ku crosstalk. Crosstalk imachitika pamene chizindikiro chikusokoneza mayendedwe oyandikana nawo, zomwe zimapangitsa kuti ma sign achepetse. Kuti muchepetse zotsatira za crosstalk, gwiritsani ntchito njira zosiyanitsira anthu awiriawiri, kutchingira, ndi magawo oyenera apandege.
c. Mphamvu Umphumphu:Kusunga kugawa kwamphamvu kwamphamvu pa bolodi ndikofunika kwambiri kuti ma signal azitha kufalikira. Phatikizani ma decoupling capacitor okwanira, ndege zapansi, ndi ndege zamagetsi kuti muwonetsetse kuti njira yochepetsetsa yotengera mphamvu.
d. Malingaliro a EMI/EMC:Pamene kachulukidwe ka madera akuchulukirachulukira, chiwopsezo cha Electromagnetic Interference (EMI) ndi Electromagnetic Compatibility (EMC) chimayambanso. Samalirani njira zoyenera zoyatsira pansi, njira zotchinjiriza, ndi zosefera za EMI kuti muchepetse chiwopsezo cha board ya HDI kusokonezedwa ndi ma elekitiroma akunja.
3. Zovuta pakupanga ndi kusankha zinthu:
Kupanga ndi kupanga ma board a HDI kumatha kubweretsa zovuta zosiyanasiyana chifukwa chakuchulukirachulukira. Kusankha zipangizo zoyenera ndi njira zopangira zinthu ndizofunikira kwambiri pakupanga bwino. Ganizirani izi:
a. Kupanga masanjidwe ndi kupanga:Ma board a HDI nthawi zambiri amakhala ndi zigawo zingapo, nthawi zambiri m'magulu ovuta. Konzani mosamalitsa misanjidweyo kuti igwirizane ndi kachulukidwe komwe mukufuna, poganizira zinthu monga kukula kwa kubowola, kudzera pamtundu (monga wakhungu, wokwiriridwa, kapena microvia), ndi kuyika kwake. Kukonzekera koyenera kumapangitsa kuti ma signature aziyenda bwino popanda kusokoneza kudalirika.
b. Zosankha:Sankhani zida zoyenera za laminate kutengera momwe magetsi akufunira, zofunikira pakuwongolera kutentha, komanso kutengera mtengo. Ma board a HDI nthawi zambiri amadalira zida zapadera zomwe zimakhala ndi kutentha kwa magalasi apamwamba, zinthu zotsika zotayira, komanso matenthedwe abwino. Funsani ogulitsa zinthu kuti mudziwe njira yoyenera kwambiri.
c. Kupirira Kupanga:Kukhazikika kwapang'onopang'ono komanso kuchulukirachulukira kwa matabwa a HDI kumafuna kulolerana kokulirapo. Onetsetsani kuti mwafotokozera ndikudziwitsani zomwe mukulolera kwa wopanga kuti mutsimikizire kupanga kolondola komanso koyenera.
4. Kudalirika ndi Kuganizira Mayeso:
Kudalirika kwa bolodi la HDI ndikofunikira kwambiri pakugwiritsa ntchito kwake. Kuti muwongolere kudalirika komanso kusavuta kuthetsa mavuto, lingalirani izi:
a. Design for Testability (DFT):Kuphatikizira malo oyesera, monga malo ofikirako logic analyzer kapena poyesa malire, kungathandize pakuyesa pambuyo popanga ndi kukonza zolakwika.
b. Zolinga za kutentha:Popeza matabwa a HDI nthawi zambiri amanyamula zigawo zambiri m'malo ang'onoang'ono, kasamalidwe ka kutentha kumakhala kofunikira. Gwiritsani ntchito njira zoziziritsira bwino, monga masinki otentha kapena matenthedwe, kuwonetsetsa kuti zigawo zikugwira ntchito mkati mwa malire omwe atchulidwa kutentha.
c. Zachilengedwe:Kumvetsetsa momwe chilengedwe cha HDI board chidzagwirira ntchito ndikupanga molingana. Zinthu monga kutentha kwambiri, chinyezi, fumbi, ndi kugwedezeka zimaganiziridwa kuti zitsimikizire kuti bolodi ikhoza kupirira malo omwe akufuna.
Powombetsa mkota, kupanga bolodi la HDI kumafuna kulingalira zinthu zingapo zofunika kuti mukwaniritse kachulukidwe kake, kukhathamiritsa kukhulupirika kwa ma siginecha, kutsimikizira kudalirika, ndi kuphweka kupanga. Pokonzekera mosamala ndikugwiritsa ntchito njira ya miniaturization, kulingalira kukhulupirika kwa chizindikiro ndi mfundo zotumizira, kusankha zipangizo zoyenera, ndi kuthetsa nkhani zodalirika, mukhoza kuzindikira luso lamakono la HDI muzojambula zanu.Shenzhen Capel Technology Co., Ltd. yakhala ikukhudzidwa kwambiri ndi ma board ozungulira kwa zaka 15. Ndi okhwima ndondomeko otaya, luso patsogolo ndondomeko, ntchito akatswiri luso, wolemera ntchito zinachitikira ndi luso luso, tapambana chikhulupiriro cha makasitomala. Ndipo nthawi iliyonse titha kupeza mwayi wamsika wa polojekiti ya kasitomala.
