Aliyense wosanjikiza High Density Interconnected PCB
MFUNDO YOYENERA KUKHALA WA HDI
HDI imayimira High Density Interconnector, yomwe ndi mtundu wa PCB wopanga (ukadaulo), wogwiritsa ntchito akhungu / oikidwa m'manda kudzera muukadaulo kuti azindikire kuchuluka kwa mizere yogawa. Ikhoza kukwaniritsa miyeso yaying'ono, ntchito zapamwamba komanso zotsika mtengo. HDI PCB ndi kufunafuna okonza, mosalekeza kukula kachulukidwe mkulu ndi mwatsatanetsatane. Zomwe zimatchedwa "zapamwamba" sizimangowonjezera magwiridwe antchito a makina, komanso zimachepetsa kukula kwa makina. Ukadaulo wa High Density Integration (HDI) utha kupangitsa kapangidwe kazinthu zomaliza kukhala kakang'ono kwambiri, kwinaku akukwaniritsa miyezo yapamwamba yamagetsi ndi magwiridwe antchito.
HDI PCB imaphatikizapo kubowola laser akhungu kudzera ndi makina kubowola akhungu kudzera. Ukadaulo woyendetsa pakati pa zigawo zamkati ndi zakunja nthawi zambiri umatheka kudzera munjira monga kukwiriridwa, osawona kudzera, mabowo osungidwa, mabowo oyenda, kuwoloka akhungu / kukwiriridwa kudzera, kudzera m'mabowo, akhungu kudzera pakudzaza ma electroplating, waya wabwino pang'ono ndi mabowo ang'onoang'ono. mu diski, etc.
Pali mitundu ingapo ya HDI PCB: 1 wosanjikiza, 2 wosanjikiza, 3layer, 4 wosanjikiza ndi kulumikizana kulikonse.
● Mapangidwe a 1 wosanjikiza HDI : 1+N+1 (kukakamiza kawiri, kubowola laser kamodzi).
● Mapangidwe a 2 wosanjikiza HDI : 2 + N + 2 (kukakamiza 3 nthawi, laser kubowola kawiri).
● Mapangidwe a 3 wosanjikiza HDI : 3 + N + 3 (kukakamiza 4 nthawi, laser kubowola 3 nthawi).
● Mapangidwe a 4 wosanjikiza HDI : 4 + N + 4 (kukakamiza 5 nthawi, laser kubowola 4 nthawi).
Kuchokera pazipangidwe zapamwambazi, tinganene kuti kubowola laser kamodzi ndi 1 wosanjikiza HDI, kawiri ndi 2 wosanjikiza HDI, ndi zina zotero. Kulumikizana kulikonse kumatha kuyambitsa kubowola kwa laser kuchokera pa bolodi loyambira. Mwanjira ina, chomwe chiyenera kubowoleredwa ndi laser musanakanize ndi HDI iliyonse yosanjikiza.
Lingaliro la Design la HDI
1.Tikakumana ndi mapangidwe omwe ali ndi mabowo m'dera la BGA la PCB yamitundu yambiri, koma chifukwa cha zovuta za danga, tiyenera kugwiritsa ntchito mapepala ang'onoang'ono a BGA ndi mabowo ang'onoang'ono kuti tikwaniritse malowedwe a bolodi lonse, tingapange bwanji? Tsopano tikufuna kuwonetsa HDI yolondola kwambiri PCB yotchulidwa pafupipafupi mu ma PCB motere.
Kubowola kwachikhalidwe kwa PCB kumakhudzidwa ndi chida chobowola. Pamene bowo lobowola kukula kufika 0.15mm, mtengo kale kwambiri ndipo n'zovuta kusintha kwambiri. Komabe, chifukwa cha malo ochepa, pamene kukula kwa dzenje la 0.1mm kokha kungatengedwe, lingaliro la mapangidwe a HDI likufunika.
2. Kubowola kwa HDI PCB sikudaliranso kubowola kwachikhalidwe, koma kumagwiritsa ntchito luso la laser kubowola (nthawi zina amatchedwanso laser board). Kubowola dzenje kukula kwa HDI zambiri 3-5mil (0.076-0.127mm), mzere m'lifupi ndi 3-4mil (0.076-0.10mm), kukula kwa solder ziyangoyango akhoza kuchepetsedwa kwambiri, kotero kugawa mizere zambiri angapezeke pa unit area, zomwe zimapangitsa kuti pakhale kulumikizana kwakukulu.
Kutuluka kwaukadaulo wa HDI kwasintha ndikulimbikitsa chitukuko chamakampani a PCB, kupangitsa kuti BGA yowundana, QFP, ndi zina zambiri zikonzedwe pa HDI PCB. Pakalipano, luso la HDI lakhala likugwiritsidwa ntchito kwambiri, pakati pawo 1 wosanjikiza HDI wakhala akugwiritsidwa ntchito kwambiri popanga PCB ndi 0.5pitch BGA. Kukula kwaukadaulo wa HDI kukuyendetsa chitukuko chaukadaulo wa chip, womwe umapangitsa kupita patsogolo ndi kupita patsogolo kwaukadaulo wa HDI.
Masiku ano tchipisi cha 0.5pitch BGA chayamba kulandiridwa pang'onopang'ono ndi akatswiri opanga mapangidwe, ndipo zolumikizira zogulitsira za BGA zasintha pang'onopang'ono kuchoka pakatikati kapena mawonekedwe okhazikika kukhala mawonekedwe okhala ndi chizindikiro komanso zotuluka pakatikati zomwe zimafunikira waya.
3. HDI PCB nthawi zambiri amapangidwa pogwiritsa ntchito stacking njira. Kuchuluka kwa stacking kumachitidwa, ndipamwamba luso lapamwamba la bolodi. Wamba HDI PCB kwenikweni zaunjika kamodzi, pamene mkulu wosanjikiza HDI amagwiritsa kawiri kapena kuposerapo stacking luso, komanso apamwamba PCB matekinoloje monga stacking dzenje, kudzaza dzenje ndi electroplating ndi molunjika laser kubowola, etc.
HDI PCB ndi yabwino kugwiritsa ntchito luso lapamwamba la msonkhano, ndipo magwiridwe antchito amagetsi ndi kulondola kwazizindikiro ndizokwera kuposa PCB yachikhalidwe. Kuphatikiza apo. HDI ili ndi kusintha kwabwinoko pakusokoneza pafupipafupi kwa wailesi, kusokoneza mafunde amagetsi, kutulutsa kwamagetsi ndi matenthedwe amafuta, ndi zina zambiri.
Kugwiritsa ntchito
HDI PCB ili ndi mawonekedwe osiyanasiyana ogwiritsira ntchito pazinthu zamagetsi, monga:
-Big Data & AI : HDI PCB ikhoza kupititsa patsogolo khalidwe lachidziwitso, moyo wa batri ndi kugwirizanitsa ntchito o mafoni a m'manja, ndikuchepetsa kulemera kwake ndi makulidwe awo. HDI PCB ikhoza kuthandiziranso chitukuko cha matekinoloje atsopano monga kulankhulana kwa 5G, AI ndi IoT, ndi zina zotero.
-Automobile : HDI PCB imatha kukwaniritsa zovuta komanso zodalirika zamakina amagetsi apagalimoto, ndikuwongolera chitetezo, chitonthozo ndi luntha zamagalimoto. Itha kugwiritsidwanso ntchito pazinthu monga radar yamagalimoto, kuyenda, zosangalatsa komanso kuyendetsa galimoto.
-Medical : HDI PCB imatha kuwongolera kulondola, kukhudzika ndi kukhazikika kwa zida zamankhwala, ndikuchepetsa kukula kwake ndikugwiritsa ntchito mphamvu. Itha kugwiritsidwanso ntchito m'magawo monga kujambula kwachipatala, kuyang'anira, kuzindikira matenda ndi chithandizo.
Ntchito zazikulu za HDI PCB zili m'mafoni a m'manja, makamera a digito, AI, zonyamula IC, ma laputopu, zamagetsi zamagalimoto, maloboti, ma drones, ndi zina zambiri, zomwe zimagwiritsidwa ntchito kwambiri m'magawo angapo.
