Mawu Oyamba
HDI ndi chidule cha High-Density Interconnect.Ndi njira yovuta yopangira PCB.Ukadaulo wa HDI PCB utha kufooketsa matabwa osindikizidwa m'munda wa PCB.Ukadaulo umaperekanso magwiridwe antchito apamwamba komanso kachulukidwe kakang'ono ka mawaya ndi mabwalo.
Mwa njira, matabwa ozungulira a HDI amapangidwa mosiyana ndi matabwa osindikizidwa omwe amasindikizidwa.
Ma PCB a HDI amayendetsedwa ndi ma vias ang'onoang'ono, mizere ndi mipata.HDI PCBs ndizopepuka kwambiri, zomwe zimagwirizana kwambiri ndi miniaturization yawo.
Kumbali inayi, HDI imadziwika ndi kufala kwafupipafupi, kuwongolera ma radiation osafunikira, komanso kuwongolera kwa PCB.Chifukwa cha miniaturization ya bolodi, kachulukidwe ka board ndiokwera kwambiri.
Microvias, akhungu ndi kukwiriridwa vias, mkulu ntchito, zipangizo woonda ndi mizere zabwino ndi zizindikiro za HDI osindikizidwa matabwa dera.
Mainjiniya ayenera kumvetsetsa bwino momwe amapangidwira komanso kupanga HDI PCB.Ma Microchips pa HDI osindikizidwa matabwa oyendera amafunikira chidwi chapadera panthawi yonse ya msonkhano, komanso luso lapamwamba la soldering.
M'mapangidwe ang'onoang'ono monga ma laputopu, mafoni am'manja, ma HDI PCB ndi ocheperako kukula komanso kulemera kwake.Chifukwa cha kukula kwawo kochepa, ma HDI PCBs samakondanso ming'alu.
HDI Kudzera
Vias ndi mabowo mu PCB kuti ntchito magetsi kulumikiza zigawo zosiyanasiyana PCB.Kugwiritsa ntchito zigawo zingapo ndikulumikiza ndi vias kumachepetsa kukula kwa PCB.Popeza cholinga chachikulu cha bolodi HDI ndi kuchepetsa kukula kwake, vias ndi chimodzi mwa zinthu zofunika kwambiri.Pali mitundu yosiyanasiyana yamabowo.
Kudzera dzenje kudzera
Imadutsa mu PCB yonse, kuchokera pamwamba mpaka pansi, ndipo imatchedwa via.Panthawiyi, amagwirizanitsa zigawo zonse za bolodi losindikizidwa.Komabe, vias amatenga malo ambiri ndi kuchepetsa chigawo danga.
Akhungu kudzera
Akhungu vias chabe kulumikiza wosanjikiza akunja kwa wosanjikiza wamkati wa PCB.Palibe chifukwa kubowola PCB yonse.
Kukwiriridwa kudzera
M'manda vias ntchito kulumikiza zigawo zamkati za PCB.Vis okwiriridwa sikuwoneka kuchokera kunja kwa PCB.
Micro kudzera
Micro vias ndi ang'onoang'ono kudzera kukula zosakwana 6 mils.Muyenera kugwiritsa ntchito kubowola laser kuti mupange ma micro vias.Chifukwa chake, ma microvias amagwiritsidwa ntchito pama board a HDI.Izi zili choncho chifukwa cha kukula kwake.Popeza muyenera chigawo kachulukidwe ndipo sangathe kuwononga danga HDI PCB, ndi chanzeru m'malo vias wamba ndi microvias.Kuphatikiza apo, ma microvias samavutika ndi zovuta zowonjezera kutentha (CTE) chifukwa cha migolo yawo yayifupi.
Stackup
HDI PCB stack-up ndi gulu-ndi-wosanjikiza bungwe.Chiwerengero cha zigawo kapena milu ingadziwike ngati pakufunika.Komabe, izi zitha kukhala zigawo 8 mpaka 40 kapena kupitilira apo.
Koma chiwerengero chenicheni cha zigawo zimadalira kachulukidwe ka zizindikirozo.Multilayer stacking ingakuthandizeni kuchepetsa kukula kwa PCB.Zimachepetsanso ndalama zopangira.
Mwa njira, kudziwa kuchuluka kwa zigawo pa HDI PCB, muyenera kudziwa kukula ndi maukonde pa wosanjikiza aliyense.Mukawazindikira, mutha kuwerengera masanjidwe ofunikira pa bolodi lanu la HDI.
Malangizo opangira HDI PCB
1. Kusankha chigawo cholondola.Ma board a HDI amafunikira ma SMD ndi ma BGA ochepa kuposa 0.65mm.Muyenera kusankha mwanzeru momwe amakhudzira mtundu, kufufuza m'lifupi ndi HDI PCB stack-up.
2. Muyenera kugwiritsa ntchito ma microvias pa HDI board.Izi zikuthandizani kuti mupeze kawiri danga la via kapena zina.
3. Zida zomwe zili zothandiza komanso zogwira mtima ziyenera kugwiritsidwa ntchito.Ndikofunikira kwambiri pakupanga kwazinthu.
4. Kuti mupeze lathyathyathya PCB pamwamba, muyenera kudzaza kudzera mabowo.
5. Yesani kusankha zipangizo zomwe zili ndi mlingo wofanana wa CTE pamagulu onse.
6. Samalani kwambiri ndi kayendetsedwe ka kutentha.Onetsetsani kuti mwakonza bwino ndikukonza zigawo zomwe zingathe kuwononga kutentha kwakukulu.

Ili ku Shenzhen, ANKE PCB ndi katswiriNtchito yopanga PCBwopereka zaka zopitilira 10 mumakampani opanga zamagetsi.Tapanga matabwa osindikizidwa ndimsonkhano wamayiko opitilira 80 padziko lonse lapansi.Kukhutitsidwa kwamakasitomala athu ndi pafupifupi 99%, ndipo timanyadira kupereka chithandizo chabwino kwambiri pozungulira.
Timagwira ntchito mokhazikika popereka makampani okhala ndi mitundu yonse komanso yapamwamba kwambiri ya PCB, msonkhano wa PCB ndi ntchito zopezera zinthu zina.za prototype, zazing'ono / zapakatikati / zamtundu wapamwamba pamaziko a 2,000 square metres ndi antchito aluso opitilira 400. Tadzipereka kupereka ntchito zonse zamagetsi zomwe zingathandize opanga PCB kubweretsa ntchito zawo pamsika pa nthawi komanso pa bajeti.
Mitengo yathu imatha kusintha kutengera kupezeka ndi zinthu zina zamsika.Tikutumizirani mndandanda wamitengo yomwe yasinthidwa kampani yanu italumikizana nafe kuti mumve zambiri.
Mtengo wotumizira umadalira momwe mumasankhira katunduyo.Express ndiye njira yachangu komanso yodula kwambiri.Ndi seafreight ndiyo njira yabwino yothetsera ndalama zambiri.Ndendende mitengo ya katundu titha kukupatsani ngati tidziwa zambiri za kuchuluka, kulemera kwake ndi njira.Chonde titumizireni kuti mudziwe zambiri.
Inde, nthawi zonse timagwiritsa ntchito ma CD apamwamba kwambiri.Timagwiritsanso ntchito kulongedza kwapadera kwa zinthu zoopsa komanso zosungirako zoziziritsa zovomerezeka za zinthu zomwe zimakhudzidwa ndi kutentha.Katswiri wazolongedza ndi zofunika kulongedza zomwe sizili mulingo zitha kubweretsa ndalama zina.
Kwa zitsanzo, nthawi yotsogolera ndi pafupifupi masiku 7.Pakupanga misa, nthawi yotsogolera ndi masiku 20-30 mutalandira malipiro a deposit.Nthawi zotsogola zimakhala zogwira mtima (1) talandira ndalama zanu, ndipo (2) tili ndi chilolezo chanu chomaliza pazogulitsa zanu.Ngati nthawi zathu zotsogola sizikugwira ntchito ndi tsiku lomaliza, chonde tsatirani zomwe mukufuna pakugulitsa kwanu.Nthawi zonse tidzayesetsa kukwaniritsa zosowa zanu.Nthawi zambiri timatha kutero.
Inde, tikhoza kupereka zambiri zolembedwa kuphatikizapo Zikalata Analysis / Conformance;Inshuwaransi;Zoyambira, ndi zolemba zina zotumiza kunja ngati pakufunika.
