Kumabhodi amancane, ukwesekwa kwephaneli kanye ne-warpage yokugeleza kabusha kufanele kuqashelwe ngoba i-PCB eyamukelekayo ngosayizi ekushiseni kwegumbi isengaphambuka ngesikhathi sokuhlanganiswa uma ukusatshalaliswa kwethusi kanye nobunzima bokushisa kungavamile kakhulu.

6. Ukuphathwa Kokushisa Ngaphandle Kwemvilophu Yokupholisa Yekilasi Ledeskithophu

I-tablet ebiyelwe inikeza ivolumu elinganiselwe yabasabalalisi bokushisa, amashidi e-graphite noma ezinye izinto zokushisa ezisezingeni lomkhiqizo. Ngakho-ke , ithusi le-PCB, ama-thermal vias kanye nokubekwa kwezingxenye kuhlanganyela endleleni yokushisa, kodwa izinga lokushisa lokugcina lincike ekwakhiweni kwemishini yonke kanye nephrofayili yokusebenza.

Ithebhulethi ayinasikhala esiningi sama-heatsink noma amafeni esitayela sedeskithophu, ngakho-ke ukwakheka kokushisa kuvame ukuncika ekuqhubeni nasekusabalaleni ebhodini, izihlangu, i-graphite, ozimele noma ezinye izakhiwo zemishini ezikhethwe yithimba lomkhiqizo. Umnikelo we-PCB ukulondoloza izindawo zethusi, ama-via okushisa kanye nokubekwa kwezingxenye ezisekela lezo zindlela. Abalawuli bamandla aphezulu kanye namadivayisi okushaja kufanele futhi kubuyekezwe ukuminyana kwethusi lendawo ukuze izinqumo zokukhulula ukushisa zingaphazamisi ukugeleza kwamandla kagesi noma kokushisa.

Ukubuyekezwa kokukhiqiza kungabhekana nemiphumela yokukhiqiza kusetshenziswa isiqondiso sokuphathwa kokushisa kwe-PCB, kuyilapho ikhasimende ligcina ubunikazi bokulingisa ukushisa kwezinga ledivayisi kanye nemikhawulo yokwamukelwa. Lo mehluko uvimbela ifektri ekuthembiseni izinga lokushisa lokugcina lobuso ibhodi elingenalutho lodwa elingenakuliqinisekisa.

Ingozi yokushisa ihlotshaniswa nenduduzo yomsebenzisi kanye nokuguga kwebhethri, kodwa ifektri ayikwazi ukuqinisekisa leyo miphumela ku-PCBA engenalutho yodwa. I-NPI kufanele ichaze ukuhlolwa kwezinga lebhodi—njengokusetshenziswa kwamanje kanye nokubonwa kwezinga lokushisa ezindaweni zomthwalo ezivunyelwene ngazo—ngokuhlukile ekuqinisekisweni kokushisa kwedivayisi ephelele. Lokhu kunikeza abathengi ubufakazi obunengqondo bokukhiqiza ngaphandle kokuguqula lesi sihloko sibe isimangalo esingasekelwa sokuthi into eyodwa ye-PCB noma isisindo sethusi ixazulula ngokuzenzakalelayo ukushisa kwethebhulethi.

Umklamo wokushisa kwamathebulethi ubuswa yiqiniso lokuthi ukushisa kufanele kushiye indawo encane, evalwe kakhulu ngaphandle komoya wesitayela sedeskithophu. Ibhodi lingahambisa ukushisa kube yizivikelo, amafilimu e-graphite, ozimele noma ezinye izisakazo, kodwa lezo zixhumi ziyingxenye yomklamo womshini womkhiqizo. Ukukhiqiza kufanele kulondoloze izindawo zokuthintana, izindawo zethusi, ama-pad avele kanye nama-array adala indlela ehlosiwe yezinga lebhodi.

Ikhwalithi yokuhlanganisa nayo ithinta ukuziphatha kokushisa. Ukungafakwa kwe-solder okwanele ngaphansi kwedivayisi yamandla evuliwe, ukuphuma ngaphandle kwefasitela lenqubo elamukelekile noma isikhombimsebenzisi sokushisa esiphakanyisiwe kungakhuphula izinga lokushisa lendawo. Ngakho-ke ukuhlolwa nokuthuthukiswa kwenqubo kufanele kugxile ezingxenyeni zangempela ezishisayo ezitholwe yithimba lokuklama. Ukuze kuqinisekiswe, chaza umthwalo womsebenzi, isimo sendawo kanye nephuzu lokulinganisa; ngaphandle kwalokho "ukuhlolwa kokushisa" kungaveza imiphumela engaguquki kuzo zonke izindawo zokukhiqiza kanye nezinhlobo eziningi.

Iphuzu lokuguqula eliwusizo

Uma ithebhulethi yakho i-PCBA inendawo eshisayo eyaziwayo eduze kwe-SoC, ishaja noma isekethe yamandla okubonisa, nikeza imikhawulo yokushisa-yemishini ngephakheji ye-Gerber/ODB++. I-Highleap ingabuyekeza ukukhiqizwa okuzungeze ama-thermal vias, ibhalansi yethusi kanye nokufinyelela kokuhlanganiswa ngaphandle kokuthi ithatha indawo ye-thermal qualification yezinga lesistimu.

7. Ukuhlanganiswa kwe-Tablet PCBA, Ukuhlolwa kanye nokuhlolwa kwe-Interface

Ukuhlanganiswa ngokuvamile kuhilela ama-passive amancane, ama-IC acwebezelayo, izixhumi zebhodi noma ze-FPC, futhi emiklamweni eminingi, amaphakheji e-BGA. Ukwakheka kwe-stencil, ukuqinisekiswa kwengxenye yokuqala kanye nokugeleza kabusha okuzinzile kumele kubhekele isisindo esixubile sokushisa kanye nokubekwa okuxineneyo.

I-PCBA yethebhulethi ihlanganisa ama-IC acwebezelayo namakhamera, amamakrofoni, izinzwa, izixhumi ze-FPC kanye nezingxenye zokuvikela. Ukuqinisekiswa kwengxenye yokuqala kubalulekile ngoba amaphutha okuqondiswa kwezixhumi ezincane eziphindaphindwayo noma izinzwa kungaba nzima ukuwabona ngemva kokufakwa kwezihlangu. Uhlelo lwenqubo kufanele luchaze ukuthi izihlangu zibekwa nini, ukuthi yimaphi amalunga ahlala engahlolwa, nokuthi ngabe yiziphi izixhumi noma amamojula adinga ukuhlanganiswa ngesandla noma kwesibili ngemva kokugeleza kabusha kwe-SMT eyinhloko.

I-AOI iyasebenza ekubekweni okubonakalayo kanye nezimo zokusoda; i-X-ray ingangezwa emajoyintini afihliwe lapho kufanele khona. Ukuhlolwa kokusebenza kufanele kusebenzise ama-interface akhona ngempela ku-SKU: ukuxhumana kokubonisa/kokuthinta, ukushaja, i-USB, amakhamera, izinzwa, i-wireless kanye neminye imisebenzi echazwe ngamakhasimende.

Ububanzi bokukhiqiza bungahlanganisa ukuhlanganiswa kwe-SMT nokuhlolwa okusebenzayo uma kutholakala izinto ezidingekayo, i-firmware kanye nezindinganiso zokwamukelwa.

Ukuqinisekiswa kokusebenza kufanele kuhlelwe nge-interface: amandla nokushaja, ukubonisa/ukuthinta, i-USB, ukuxhumana okungenantambo/imojula, amakhamera/izinzwa nomsindo lapho kufakiwe. Ifektri kufanele isebenzise i-firmware echazwe ngamakhasimende, izinto ezifakiwe kanye nemikhawulo yokwamukelwa; i-AOI noma i-X-ray ayikwazi ukufaka esikhundleni salokhu kuhlolwa kokusebenza. Ukuze uthole ukwakhiwa okuphindaphindiwe, xhumanisa iphrofayili yokuhlola ne-SKU eqondile ukuze amaselula angakhethwa, imemori noma amakhamera angahlolwa ngokumelene nokucushwa okungalungile.

Ibhodi elikhulu lethebhulethi elincane livame ukuhlanganisa izingxenye eziqondile nezixhumi ze-FPC ezibuthakathaka kanye nemiphetho yebhodi evezwe ngomshini. Umklamo wokuvula nge-stencil, ukwesekwa kwebhodi, ukunemba kokubekwa kanye nephrofayili yokugeleza kabusha kufanele kubhekele lokhu kuhlanganiswa. Amajoyinti okuxhumanisa abukeka amukelekile ngaphambi kokuhlanganiswa kwe-enclosure angahluleka kamuva uma isiqondiso sokufakwa kwekhebula noma umthwalo wendlu kungacatshangwanga, ngakho-ke ukuhlolwa kwesihloko sokuqala kufanele kufake phakathi ukuhlanganiswa komshini lapho kusebenziseka khona.

Ukuhlolwa kokusebenza kufanele kulandele ukwakheka komkhiqizo kunokuhlola okujwayelekile kwe-PCBA. Ukuqaliswa kokubonisa, ukuxhumana kokuthinta, amabhasi ekhamera, ukuphazamiseka kwenzwa, ukushaja, i-USB, i-wireless nomsindo kungadinga izinto noma isofthiwe ehlukene. Ngokuvamile kusebenza kahle ukuchaza ukuhlolwa okufushane kokukhiqiza okubamba amaphutha okuhlanganisa bese kushiya ukuqinisekiswa komkhiqizo okugcwele kubunjiniyela. Isihluthulelo ukulandeleka: ukubuyekezwa kwebhodi lokurekhoda, i-firmware, inguqulo ye-fixture kanye nomphumela wokuhlola ukuze izinkinga zokuhlanganiswa ngezikhathi ezithile zingahlotshaniswa nesimo esithile sokwakha.

8. Izidingo Zokuthola Imithombo kanye Ne-RFQ Zezinhlelo Ze-PCB Zekhompyutha Yamathebhulethi

Ikhotheshini ye-PCB yekhompyutha yethebhulethi kufanele ibonise ukubuyekezwa kwehadiwe, inketho yokuxhumeka efakiwe, isikhombikubona sokubonisa/sokuthinta, isixhumi sebhethri, i-stack-up kanye nanoma yiziphi izidingo zokulawulwa kwe-impedance. Ukushintsha izingxenye kudinga ukunakekelwa okukhethekile lapho izingxenye zisebenzisana ne-firmware, ukusebenza kwe-RF, ukulingana kwesixhumi noma ukuziphatha kwamandla.

Isiphetho

Ukukhiqizwa kwe-PCB yamathebhulethi ngokuyinhloko kuyinkinga yokuhlanganiswa okuhlangene: imishini emincane, amandla ebhethri, ukuxhumana kokubonisa/kokuthinta kanye nemisebenzi ye-RF yokuzikhethela kufanele kulawulwe ndawonye. Indlela efanele yokuhlanganisa kanye nokuhlanganisa kufanele ilandele umklamo okhishwe esikhundleni sethempulethi "yebhodi yamathebhulethi" ejwayelekile.

Ama-Tablet BOM aqukethe izingxenye eziningana ezingafaneleki ukufakwa esikhundleni esingalawulwa: amaprosesa, imemori/isitoreji, ama-PMIC, abalawuli bokubonisa/bokuthinta, amakhamera, amadivayisi e-RF, izixhumi kanye nezingxenye zamandla. Ukulingana kwefomu nephakeji akuqinisekisi i-firmware, isikhathi, ukulingana kokushisa noma komshini. Ukuthengwa kufanele kuchaze abakhiqizi abagunyaziwe kanye nezinye izingxenye zalezi zingxenye, kuyilapho ama-passive empahla angasebenzisa i-AVL ebanzi uma izidingo zikagesi zivuma.

I-RFQ enamandla yenza ikhotheshini ifane. Faka phakathi i-stack-up yebhodi, ukujiya okuqediwe, imininingwane ye-flex/rigid-flex uma isetshenziswa, izidingo zokulawula ukuvinjelwa, izinombolo zezingxenye zokubonisa/zokuthinta, isikhombimsebenzisi sebhethri, i-wireless variant, imfuneko yokuhlela kanye nokumbozwa okulindelekile kokuhlolwa. I-Highleap ingabe ihlukanisa izindleko zokukhiqiza, ukuthola, ukuhlanganisa, ukuhlola, ukulungisa kanye nokuhlola futhi ibone ukuthi yiziphi izidingo eziqhuba isikhathi sokuhola. Lokho kudala indlela ecacile kusukela ku-prototype kuya ekukhiqizeni okuphindaphindiwe kunokucaphuna ku-Gerbers kanye ne-BOM kuphela.

Iphuzu lokuguqulwa kwe-RFQ

Ukuze uthole i-PCB entsha yekhompyutha yethebhulethi , thumela imidwebo ye-Gerber/ODB++ ekhishwe, umdwebo wokwenziwa, i-BOM, i-CPL, imidwebo ye-flex/mating kanye nokuhlolwa okulindelwe ndawonye. Ukubuyekezwa kungagxila ekukhuleni kwebhodi elincane, ukuxhumanisa, ingozi yenqubo ye-BGA kanye nokulawula okuhlukile esikhundleni semininingwane yethebhulethi ejwayelekile.
