I-KB-6164 Laminate kanye ne-KB-6064 Preg for Controlled Multilayer Stackups

I-KB-6164 iyi-laminate embozwe ngethusi elungisiwe, kuyilapho i-KB-6064 iyi-prepreg efanayo engakalungiswa esetshenziselwa ukubopha ukwakhiwa kwe-PCB enezingqimba eziningi. I-Highleap Electronics ivame ukuthola lezi zinto njengengxenye ye-oda le-PCB noma le-PCBA eliqediwe bese iziguqula zibe yi-stackup ekhishwe enobukhulu be-dielectric obulawulwayo, ithusi kanye nokuhlolwa.

Izindima ze-PCB ze-Laminate, Preg kanye ne-Finished

A buyer who only specifies the laminate name leaves major decisions unresolved: glass style, okuqukethwe kwe-resin, pressed thickness, copper treatment, core distribution and final thickness. Highleap resolves these through a released stackup, not through purchasing substitution on the shop floor.

Indlela Yokuchaza Izakhiwo Ezisemthethweni

I-Kingboard ibala i-KB-6164 njenge-standard-Tg, ehambisana ne-FR-4 engenalo i-lead-free-process ene-Tg ejwayelekile engu-140°C, i-Td 330°C, ukwanda okuphelele kwe-Z-axis okungu-3.5% kanye ne-CTI 175 V. Lawa manani akhomba isigaba sezinto ezibonakalayo futhi awusizo ekuqhathaniseni. Aziqinisekisiwe ukuthi zicacisiwe yini izincazelo zebhodi eliqediwe.

Izindlela zokuhlola azikwazi ukushiywa

I-Tg iyahlukahluka nge-DSC, i-TMA noma i-DMA. I-Dk ne-Df ziyahlukahluka ngokuvama kokuhlolwa, okuqukethwe kwe-resin kanye nendlela. Amadokhumenti okuthenga kufanele alondoloze indlela lapho inani libalulekile, ngaphandle kwalokho amashidi amabili edatha abonakala ephikisana angasebenzisa izilinganiso ezihlukile.

Amanani ezinto ezibonakalayo, amanani okuklama kanye nemiphumela elinganisiwe ahlukile

• Inani lezinto ezibonakalayo: idatha ejwayelekile eshicilelwe yiKingboard.
• Inani lomklamo: inombolo ethile yokwakha esetshenziswa ngumenzi wokwenza amamodeli e-stackup.
• Umphumela olinganisiwe: idatha evela kukhuphoni noma ukuhlolwa kwebhodi eliqediwe.

Ukudideka kwala mazinga obufakazi kuyimbangela evamile yezingxabano ze-impedance.

Ubukhulu, Ukulungiselela Ngaphambi Kokukhulelwa, Ithusi Nokujiya Okucindezelwe

Ubukhulu be-core abukaqediwe

Ubukhulu obuqediwe bulingana nama-core ahlanganisiwe, ama-prepreg acindezelwe, ithusi kanye nokubekezelelana kwenqubo. Ubuningi bethusi bushintsha ukugeleza kwe-resin, ngakho-ke i-prepreg efanayo ingacindezela ngendlela ehlukile phakathi kwesendlalelo sendiza kanye nesendlalelo sesignali esingavamile.

Isitayela sengilazi kanye nokuqukethwe kwe-resin kuthinta indlela yokugcwalisa kanye nokuziphatha kukagesi

Ingilazi encane ingasekela ama-dielectric amancane, kuyilapho ingilazi esindayo inganikeza ukujiya okwengeziwe kanye nokuqina komshini. Okuqukethwe kwe-resin kunquma ukuthi kungakanani ukugeleza okutholakalayo ukugcwalisa ithusi eliqoshwe. Inhlanganisela ekhethiwe kumele ihlangabezane nokujiya, ukugcwaliswa kwe-resin, ukubhaliswa, ukubhobozwa kanye nokungangeni.

I-foil yethusi kumele ibhalwe kahle

I-foil yokuqala, ithusi eliqediwe kanye nethusi elifakwe ipulasitiki kuyincazelo ehlukile. Nge-impedance elawulwayo noma imigqa emincane, ukwelashwa kwethusi kanye nephrofayili kungabaluleka. I-stackup kufanele ibone ithusi eliqediwe ngeleveli kanye nanoma yimuphi umkhawulo wephrofayili yethusi ovunyiwe.

Ukuze uthole umongo womklamo wezingqimba eziningi, sebenzisa umhlahlandlela we-PCB stackup we-Highleap . Uchaza ukuthi kungani ukutholakala kwezinto kanye nekhono lokukhiqiza kumele kucatshangelwe ngaphambi kokuba ukwakheka kuqandwe.

Isitoreji, Ukulawulwa Kwezindawo kanye Nokulandelela

Izinqwaba ezahlukene zingaba nokwehluka okuvamile kokuqukethwe kwe-resin kanye nokugeleza kwayo. Ukuze kube nobukhulu obudingekayo noma ukwakheka kwe-impedance, izinqwaba kanye nokwakhiwa kufanele kulawulwe. I-prepreg ephelelwe yisikhathi noma egcinwe ngendlela engafanele akufanele isetshenziswe ngaphandle kokuhlolwa okuvunyiwe.

Ukulandeleka kufanele kuhambisane nengozi yomkhiqizo

Ibhodi lezentengiselwano elivamile lingadinga ubunikazi bezinto ezibonakalayo kanye namarekhodi ezindawo. Uhlelo olulawulwayo noma oluthembekile kakhulu lungadinga izitifiketi, amarekhodi okugcina, ukulawulwa kokubuyekezwa kwe-stackup kanye namakhuphoni agciniwe. I-RFQ kufanele isho amadokhumenti adingekayo esikhundleni sokucabanga ukuthi yonke i-oda ifaka iphakheji efanayo.

Impedance kanye neFinished-Board Qualifired

I-Catalog Dk akufanele ikopishwe ngqo ku-impedance solver. I-core/prepreg ekhethiwe, okuqukethwe kwe-resin, iphrofayili yethusi kanye nomphumela wokucindezela kunquma inani lomklamo. I-Highleap ingaxazulula ububanzi be-trace kanye nesikhala ngemva kokukhethwa kokwakhiwa.

Lapho kudingeka khona ukulawula okulinganisiwe, umdwebo wokwenziwa kufanele ubonise ukuvimba okuqondiwe, ukubekezelelana, i-geometry yekhuphoni kanye nokulindela ukubika. Umhlahlandlela wezimfuneko zokuvimbela okulawulwayo unikeza ifomethi yokucacisa ewusizo.

Ukufaneleka kufanele kugxile ebhodini eliqediwe

Isitifiketi sezinto ezibonakalayo sifakazela ubuwena, hhayi ikhwalithi yomgodi oqediwe noma i-impedance. Kuye ngomkhiqizo, ubufakazi obuwusizo bungafaka phakathi ukujiya okucindezelwe, i-microsection, ukuhlolwa kukagesi, ikhuphoni ye-impedance, ukushintshwa kwe-soldering kanye nemiphumela yokuhlanganiswa kwesihloko sokuqala.

Isibonelo sokwakheka kwebhodi elinezingqimba eziyisithupha

Ibhodi elinezingqimba eziyisithupha lingasebenzisa ama-core amabili e-KB-6164 anephethini ahlukaniswe yi-KB-6064 prepreg, kanye nethusi langaphandle elibekwe eduze kwe-subassembly. Ukukhetha kokugcina kuncike ekujikeni okuqondiwe, ukuvinjelwa, ibhalansi yethusi kanye ne-geometry yokubhoboza. Uma umklamo udinga isikhala sesignali esingu-0.10 mm ukusuka eplanini, umenzi kumele aqinisekise ukuthi isitayela sengilazi esikhethiwe kanye nokuqukethwe kwe-resin kungacindezela kulelo nani kulo lonke iphethini langempela lethusi. Ubukhulu bekhathalogi obujwayelekile abuyona isiqinisekiso sokuthenga.
