Kugadzira Bhodhi reDunhu reNhare uye Kuungana kweHDI
Smartphone yega yega inoenderana nebhodhi remafoni rakagadzirwa kuti rikwanise kushivirira rinoyerwa muma microns—gungano rine laminated rakawanda apo nzira dzemhangura dzakatetepa kupfuura bvudzi remunhu dzinotakura zviratidzo pakati pemazana ezvikamu kubva paDC power kusvika ku millimeter-wave 5G. KuHighleap Electronics, tinogadzira mabhodhi emafoni evatengi veOEM neODM pasi rese, tichisanganisa kugadzirwa kwe12-layer HDI nekubatanidzwa kwakazara kweSMT pasi pedenga rimwe chete reISO 9001-certified. Gwaro iri rinofukidza zviri mukati mebhodhi remazuva ano remafoni, nei kushivirira kwekugadzira mafoni kuri kwakaoma, uye chii chinoparadzanisa mutengesi ane hunyanzvi kubva kune anozokubhadharisa mari yakawanda mubasa iri.
Ungave uri mainjiniya wemidziyo yemagetsi uri kuronga tape yako yekutanga yeHDI, timu yekutenga zvinhu inokodzera mubatsiri mutsva wePCB, kana kuti ODM iri kuchinja kubva pakugadzira kuenda pakugadzira—chokwadi chekugadzira pano chinoshanda zvakananga kune zvaunosarudza.

Kuumbwa kweBhodhi reDunhu reNhare
Bhodhi remagetsi refoni harisi ndiro rakatsetseka rine machipisi akabatanidzwa. Iro chivakwa chakanyatsogadzirwa chine zvidimbu zvemhangura gumi kusvika gumi nezviviri, ukobvu hwese huri pasi pe10mm, chinotakura masaini kubva kumagetsi eDC kuenda ku40 GHz RF panguva imwe chete. Chidimbu chimwe nechimwe chinoshanda basa remagetsi—kutungamirira masaini, kugoverwa kwesimba, pasi peEMI, kana RF antenna feed—uye zvidimbu izvi zvinoshanda pamwe chete nemagetsi: sarudzo paChidimbu 4 inokanganisa maitiro echiratidzo paChidimbu 7 pa5 GHz.
Ruzivo rweKugadzira
Dhizaini yekurongedza zvinhu—yakasarudzwa isati yaiswa nzira yekudzosera zvinhu—inosarudza denga remagetsi rebhodhi uye mutengo waro wekugadzira. Kugadzirisa hurongwa hwekugadzirisa zvinhu mushure mekunge nzira yatanga kushandiswa ndeimwe yezvikanganiso zvinodhura zvikuru mukugadzirwa kwePCB dzemafoni.
Substrate: Hwaro hweMashandiro Ese Emagetsi
Mabhodhi emagetsi epamusoro anoshandisa ma FR4 laminates akagadziriswa ezvikamu zvedhijitari uye zvinhu zvinorasikirwa zvishoma (Rogers RO4000, LCP) zvezvikamu zveRF. Zvinhu zvekutanga zvinosarudza dielectric constant (Dk), dissipation factor (Df), uye coefficient of thermal expansion (CTE)—ma parameter matatu anodzora kuvimbika kwechiratidzo uye kuvimbika kwenguva refu kwejoini re solder. Kusawirirana kweCTE pakati pebhodhi nemapakeji eIC kunokonzera kuneta kwejoini re solder; kusarudza substrate CTE inoenderana nemapakeji eIC anotungamira inyaya yekuvimbika, kwete sarudzo.
Onawo: A Comprehensive Guide kune Smartphone PCBs — Muchidimbu webhurocha rakazara reHighleap Electronics reruzivo rwemabhodhi emafoni kubva kuchizvarwa chekutanga kusvika kumagadzirirwo eHDI ane layer gumi nemaviri aripo iye zvino.
Maumbirwo eLayer uye Kusarudzwa kweZvinhu
Stack-up inotsanangura denga remagetsi. Heino mashandisirwo anoitwa mhando dzema layer mubhodhi rekufambisa rine ma layer gumi:
| Rukoko Rudzi | Basa Rekutanga | Verenga | Chinodiwa Chinodiwa |
|---|---|---|---|
| Chiratidzo | Data rekumhanya-mhanya, RF, nzira yekudzora | 4-6 | Impedance inodzorwa ± 10% |
| Ndege yepasi | Kudzosera magetsi, EMI shielding | 2-4 | Mhangura yakasimba, maburi mashoma |
| Power Plane | Kugoverwa kwevoltage, kugadzikana kwePDN | 1-3 | Kuramba kwakaderera, kupatsanura kwakachena |
| RF/Antena | Ma antenna e5G/Wi-Fi, anoenderana | 1-2 | Zvinhu zvinorasikirwa zvishoma Dr ≤ 3.5 |
Standard FR4 ine Dr ≈ 4.2–4.8 pa1 GHz, asi kukosha uku kunochinja kuenda pa3.7–4.0 pa5 GHz. Chiratidzo chakagadzirirwa 50Ω pa1 GHz chinoverenga 54Ω pafrequency yekushanda—zvakakwana kuti zvikundikane kuyedza kutevedzera RF. Kune zvikamu zve5G mmWave (24–40 GHz), Highleap Electronics inotsanangura zvinhu zveRogers kana LCP zvine frequency-stable Drk values uye Df iri pasi pe0.003.
Zvikamu Zvikuru uye Logic Yekuisa
Kuiswa kwechikamu kunotevera mafambiro emagetsi, ekupisa, uye ekutumira masaini—kwete nyore. Mabhuroko makuru ekushanda uye zvipingamupinyi zvawo:
