Iyo Yakazara Yekutungamira kune Semiconductor PCB Kugadzira

ziviso

Kugadzirwa kweSemiconductor PCB kunoita basa rakakosha mukurongedza machip, masisitimu ekuyedza, uye mashandisirwo emagetsi epamusoro. Mabhodhi aya akasarudzika anoshanda semabhodhi ekuyedza , mabhodhi ekutakura , makadhi ekuongorora , uye mapuratifomu einterface anoda kunyatsojeka uye kuvimbika. Kugadzirwa kweSemiconductor PCB kunosanganisira maitiro akadzorwa zvakanyanya anovimbisa kunyatsojeka, kuvimbika, uye kuenderana nemidziyo yesemiconductor.

Kubva pakurongeka kwekutanga kuenda kumusangano weSMT, nhanho yega yega inosarudza yekupedzisira bhodhi kuita uye goho. Iri gwara rinofamba kuburikidza nekuzara kwekugadzira kuyerera, ichiratidza kuti yakabatanidzwa PCBA masevhisi anofambisa sei kugadzirwa kwesemiconductor application.

Semiconductor PCB Kugadzira: Dhizaini & Rondedzero Yakakosha

High-Density Interconnect Architecture

Dhizaini optimization inotanga neHDI tekinoroji inogonesa yakanaka-pitch traces, microvias, uye mapofu-kuvigwa kuburikidza nezvimiro zveakaomesesa semiconductor mapakeji. Impedance kudzora, kusiyanisa vaviri nzira, uye crosstalk kudzikisira inochengetedza kutendeseka kwechiratidzo pane yakakwirira frequency. Zvishandiso zvakajairika zveEDA zvakaita seAltium Designer, Cadence, uye Mentor Graphics inopa dhizaini yekutarisa uye yekufananidza kugona kwakakosha pakusimbisa semiconductor PCB yekugadzira dhizaini isati yagadzirwa.

Thermal Management Strategies

Kushanda kwekupisa kwekupisa kunoda strategic layer stackup kuronga. Zvinhu zvakakosha zvekugadzira thermal zvinosanganisira:

• Metal core substrates -Yakananga kupisa conduction kubva kune yakakwirira-simba semiconductor zvishandiso kusvika pakupisa kunyura.
• Yakaiswa mari yemhangura - Localized thermal mass inoderedza kupisa kwehotspot munzvimbo dzakaoma.
• Via-mu-pedhi kuvaka -Ipfupi nzira yekupisa kubva kuchikamu kuenda kune yemukati mendarira ndege.
• Kuiswa kwepasi kwendege -Optimized stackup kumisikidza inoderedza ruzha rwemagetsi uye inowedzera kupisa kupararira.

Dhizaini yekugadzira uye testability misimboti inoshandiswa panguva ino inoderedza zvakanyanya nyaya dzekugadzira mukugadzira semiconductor PCB.

Kusarudzwa kwezvinhu muSemiconductor PCB Manufacturing

Substrate Materials uye Performance Characteristics

Kusarudzwa kwezvinhu kunosarudza mashandiro emagetsi, kugadzikana kwekupisa, uye kururama kwezvikamu mukugadzirwa kwe semiconductor PCB. High Tg FR-4 inopa mhinduro dzinoshanda pamutengo wepamusoro-soro, nepo polyimide uye mhuri dze laminate dzakanyanya kurasikirwa zvishoma dzichipa mashandiro akanaka ekugadzira magadzirirwo e high-frequency. BT resin uye ceramic substrates zvinopa kugadzikana kwakanyanya kunodiwa pamapakeji e semiconductor ane pitch yakanaka. Sarudzo yega yega yezvinhu inokanganisa kurasikirwa kwechiratidzo, coefficient yekuwedzera kwekupisa, uye kuvimbika kwenguva refu.

Lamination Process Control

Iyo lamination process inosungira akawanda mhangura-akapfeka akaturikidzana ane prepreg zvinhu pasi pekudzora tembiricha uye kumanikidzwa. Yakanyatso kurongeka masisitimu inovimbisa dhizaini-kune-layer kunyoreswa kwakakosha kune microvias uye kuvigwa vias. Vacuum lamination inodzivirira voids uye delamination, ukuwo thermal profiling inovimbisa kuzara resin kurapwa. Highleap Electronics inochengetedza yakaomesesa lamination paramita kutsigira akawanda-layer zvivakwa kubva kune akajairwa stackups kune yepamusoro HDI zvigadziriso.

Imaging, Etching, uye Drilling muSemiconductor PCB Manufacturing

Laser zvakananga Kumaging Technology

Semiconductor PCB kugadzira inoshandisa laser yakananga imaging kuti iwane yakanaka-mutsara kugadzirisa uye chaiyo pateni kufambisa. Masisitimu eLDI anobvisa mafotomasks, achipa kukurumidza kutendeuka uye nekunatsiridza kurongeka kwepamusoro-density yedunhu mapatani. Iyo yekufungidzira maitiro inotsanangura conductor mapatani pane photoresist-yakavharwa nemhangura maseru, kumisikidza hwaro hweanotevera etching mashandiro. Tight kunyoresa kutonga kunovimbisa kuti layer-to-layer alignment inosangana nezvinodiwa zvemabhodhi eATE uye probe kadhi application.

Precision Drilling uye Etching

Kemikari etching inobvisa mhangura isingadikanwi kuti igadzire mapatani edunhu ane inodzorwa trace upamhi uye nzvimbo. Mechanical drilling inogadzira kuburikidza-maburi ane yakasimba dhayamita kushivirira, nepo laser drilling inoburitsa microvias yeHDI zvimiro. Drill kudzika kudzora uye kubuda burr manejimendi kwakakosha kune yakavimbika yakapfava-kuburikidza-gomba kuumbwa, kuve nechokwadi chekuenderera kwemagetsi mukati mesemiconductor PCB yekugadzira maitiro.

Plating uye Surface Kupedzisa kweSemiconductor PCBs

Electroplating yeInterconnection

Electroplating inoisa mhangura mumakomba akacherwa kugadzira kubatanidza magetsi pakati pematanho. Yazvino density kugovera uye plating nguva yekudzora inovimbisa yunifomu yemhangura ukobvu pane iyo panel. Kuburikidza ne-gomba plating inoda kukwana mhangura yekuisa kuti isangane neIPC miyero yekuvimbika pasi pekupisa bhasikoro. Pattern plating inowedzera mhangura kune conductor traces, ichivaka ukobvu kubata zvazvino zvinodiwa mu semiconductor PCB yekugadzira maapplication.

Surface Pedzisa Sarudzo

Kupedzwa kwepamusoro kunodzivirira mhangura yakafumurwa uye kunopa nzvimbo dzinotengeswa dzekusangana kwechikamu:
