Semiconductor Packaging Trends: Kubva Chinyakare PCB kusvika Embedded Substrates

ziviso

Kurongedza kwemasemiconductor kuri kuchinja zvakanyanya sezvo maPCB emukati mesubstrate achivhara musiyano uripo pakati pemabhodhi edunhu akadhindwa echinyakare uye kurongedza kweIC kwepamusoro-soro. Sezvo Mutemo waMoore wava kusvika pamiganhu yemuviri, indasitiri iyi yachinja kutarisa kubva pakuderedza saizi dzetransistor kuenda kuhugadzirirwo hutsva hwekurongedza. Tekinoroji yemukati mesubstrate inomiririra nzvimbo yakakosha yekuchinja uko kugona kwekugadzira maPCB kwakajairika kunosangana nezvinodiwa zve semiconductor-grade usahihi.

Uku kushanduka-shanduka kunofambiswa nezvinodiwa zvekubatanidzwa kwakasiyana, uko akawanda machiplets-logic, ndangariro, uye nyanzvi processors-inofanirwa kutaurirana nekushomeka latency uye yakanyanya kunyatsoshanda. Kunzwisisa shanduko yetekinoroji iyi kwakakosha kune vagadziri vemagetsi uye vagadziri vanogadzirira chizvarwa chinotevera manyorerwo muAI, mota, uye yepamusoro-inoshanda komputa.

Evolution kubva kuPCB kuenda kuAdvanced Packaging Substrate

Kubva kuDiscrete kuenda kuIntegrated Architecture

MaPCB echinyakare akashanda seasina kupindirana mapuratifomu, masaini ekufambisa pakati pemachipisi akaiswa pamusoro pavo. Iyi nzira yakasarudzika yakapatsanura iyo chip yekurongedza maitiro kubva kubhodhi musangano, ichigadzira zvimiro zvemukati mukutendeseka kwechiratidzo uye fomu chinhu. Shanduko kune yakamisikidzwa substrate PCB tekinoroji inoshandura iyi paradigm nekubatanidza machipisi zvakananga mukati me substrate layer, kubvisa kurasikirwa kwechimiro uye kugonesa compact matatu-dimensional architecture.

Material Evolution muEmbedded Substrate PCB

Iko kushanduka kubva kuFR-4 laminate kuenda kumberi resin masisitimu inoratidza yakakosha inogonesa yakamisikidzwa substrate application. Yakajairika FR-4, nepo ichidhura-inoshanda kumabhodhi echinyakare, inoshaya kugadzikana kwedimensional uye dielectric zvivakwa zvinodiwa kune yakanaka-pitch semiconductor interconnects. Yazvino yakamisikidzwa substrate PCB madhizaini anoshandisa Ajinomoto Build-up Firimu (ABF), bismaleimide-triazine (BT) resin, uye yakasarudzika resin-yakavharwa mhangura (RCC) zvinhu zvinopa yepamusoro coefficient yemafuta ekuwedzera anoenderana nesilicon.

Kuenzanisa Kwemaitiro Pakati Pezvizvarwa

KuHighleap Electronics, takaona zvinodiwa nevatengi zvichichinja kubva kuHDI mabhodhi ekurongedza-giredhi akamisikidzwa ma substrates anoda anodzorwa impedance kushivirira pasi pe5% uye pamusoro pefitness yakatarwa akayerwa mune imwechete-digit micrometer.

Makiyi Madhiraivha Kumashure Akamisikidzwa Substrate PCB Adoption

Miniaturization Inosangana neI/O Kuputika

Yemazuva ano sisitimu-pane-chips ine mabhiriyoni ematransistors asi akatarisana neI / O density dambudziko iro rakajairwa waya bonding risingakwanise kugadzirisa.
