Umkhiqizi we-High Tg FR4 PCB we-Ezimboni, Ezezimoto, kanye Ne-Elektroniki Yamandla

Ukukhiqizwa kwe-PCB ye-High Tg FR4 kuvame ukuqhutshwa umbuzo wokuthembeka, hhayi ukukhetha ukumaketha kwe-laminate "engcono". Abathengi bacela i-High Tg FR4 uma bedinga imajini ethe xaxa ngesikhathi sokugeleza kabusha okungenalo i-lead, izinga lokushisa lokusebenza eliphakeme, ithusi elijiyile, ama-BGA amakhulu, noma ukwakhiwa kwezingqimba eziningi okucindezela i-FR4 ejwayelekile eduze kakhulu nendawo yayo yokunethezeka.

I-Highleap Electronics ibuyekeza amaphrojekthi e-High Tg FR4 kusukela kuhlelo lokusebenza emuva. Siqala ngokubheka izidingo zokushisa nezomshini zomkhiqizo, bese sinquma ukuthi ukuthuthukiswa kwezinto kuyafaneleka yini, ukuthi kuthinta kanjani ukulawulwa kwe-stackup, nokuthi kusho ukuthini ekuhlanganiseni nasekukhiqizeni okuphindaphindiwe. Ukuze uthole umongo wezinto eziseduze, bheka amabhodi wesekethe e-FR4 Tg kanye nokukhiqizwa kwe-FR4 PCB.

Uma i-High Tg FR4 iyithuthukisi elifanele

Izinto ezibonakalayo kufanele zixazulule ingozi ethile yokukhiqiza

I-High Tg FR4 iba usizo lapho ibhodi lingase libone ukucindezeleka okuphindaphindiwe kokushisa, izinga lokushisa lokusebenza eliphakeme, noma inhlanganisela yokubala kwezendlalelo, isisindo sethusi, kanye nobuningi bephakheji okuphakamisa ukukhathazeka mayelana nokuthembeka kwemigodi ehlanganisiwe noma i-warpage.

• Amabhodi okulawula ezimboni anokulindela impilo ende yokusebenza
• Amamojula kagesi ezimoto adalulwe ekujikelezeni okuphezulu kokushisa
• Amabhodi okuguqula amandla anezindawo zokusebenza zethusi esindayo noma ezishisayo
• Imiklamo eminingi enezingqimba eziningi ecebile nge-BGA esiya ekuhlanganisweni okungenalo i-lead

Uma umkhiqizo ungadali enye yalezo zingozi, i-FR4 ejwayelekile ingase ibe yisinqumo esisebenziseka kalula. Ukuthuthukiswa kwezinto kufanele kulandele imfuneko yokwakha yangempela, hhayi umkhuba.

Umongo wohlelo lokusebenza ubaluleke kakhulu kunegama elivamile

Ibhodi elilula lokulawula elinezingqimba ezimbili kanye nebhodi lamandla lezimoto elinezingqimba eziningi kungabizwa ngokuthi “izimboni,” kodwa akufaneleki isinqumo esifanayo esibalulekile. I-Highleap ibuza ukuthi ibhodi lizokwakhiwa futhi lisetshenziswe kanjani ngaphambi kokuqinisekisa isincomo se-High Tg FR4.

Lokho Abathengi Okufanele Bakuhlole Ngale Kwenombolo Ye-Tg

I-Tg yodwa ayanele ukufaneleka i-laminate

Amakhasimende avame ukucela i-Tg 170 noma i-Tg 180 FR4, kodwa umphumela oqediwe uncike nasekuziphatheni kokubola kokushisa, ukwanda kwe-Z-axis, ukuziphatha komswakama, ukunamathela kwethusi, nokuthi ngabe uhlobo olukhethiwe luyingxenye yochungechunge lokuphakelwa oluvunyiwe lokukhiqiza okuphindaphindiwe.

Uma umdwebo ubala kuphela ithagethi ye-Tg ngaphandle kokulindela okubanzi kwezinto ezibonakalayo, i-Highleap ibuyekeza ukuthi ukukhetha kufana yini nephrofayili yangempela yengozi yomkhiqizo noma ukuthi iphrojekthi idinga umndeni we-laminate oqanjwe ngegama.

Uhlu lwezinto ezivunyiwe lunciphisa ingozi yoku-oda okuphindaphindiwe

Ezinhlelweni zokukhiqiza, ingxoxo yezinto ezibonakalayo kufanele iphele ohlwini oluvunyiwe, hhayi ilebula lokusebenza elingacacile. Lokho kubaluleke kakhulu lapho ibhodi lizoshintsha lisuke ku-prototype liye ekwakhiweni kwevolumu yezimoto, yezimboni, noma kagesi.

Imiphumela Yokuqongelela, Ithusi, kanye Nokubhoboza

Ukukhetha izinto ezibonakalayo kushintsha isibuyekezo sokwenziwa

Amabhodi e-High Tg FR4 avame ukuxhunyaniswa nethusi elijiyile, izendlalelo eziningi, indawo yebhodi enkulu, noma izici ezidinga amandla omshini. Lokho kusho ukuthi ukubuyekezwa kwe-stackup akufanele kuhlanganise ukujiya kwe-dielectric kuphela kodwa futhi nebhalansi yethusi, isilinganiso se-drill aspect, ukuthembeka kwe-plating, kanye nomthelela womklamo wephaneli ku-warpage.

Lapho ibhodi liphinde lihlanganise izakhiwo zezendlalelo eziyinkimbinkimbi, i-Highleap ihlola ukuthi iphakheji yokukhiqiza iyahambisana yini ne -PCB lamination kanye nezilawuli zokukhiqiza ze-PCB ezinezendlalelo eziningi ngaphambi kokukhulula umsebenzi.

Ikhwalithi yokubhoboza kanye nokufaka amaplanga ibalulekile njengebanga le-laminate

I-laminate eqinile ayilifaki icala lesakhiwo esibi. Uma ibhodi linemigodi ejulile yesilinganiso, ithusi elisindayo, noma i-BGA fanout ejiyile, uhlelo lokubhoboza kanye neplating kufanele lubuyekezwe ngokubaluleka okufanayo nokuvunyelwa kwezinto ngokwazo.

Izinto Okufanele Uzicabangele Ngokuhlanganisa I-Warpage Nokungena-Lead

Izicelo eziningi ze-High Tg FR4 empeleni ziyizicelo zokuzinza kokuhlanganiswa

Amakhasimende avame ukucela i-High Tg FR4 ngoba abone amaphutha okuhlangana emabhodini amakhulu noma aminyene ngesikhathi sokugeleza kabusha okungenalo i-lead. Kuleso simo, impendulo efanele akuyona nje "ukusebenzisa izinto ze-Tg eziphakeme." Ukubuyekezwa kufanele futhi kucabangele ukulingana kwethusi, ukwesekwa kwephaneli, ukujiya kwebhodi, ubuningi bephakheji, kanye nephrofayili yokugeleza kabusha.

I-Highleap ibuyekeza la maphuzu kanye ne -PCB engenalo i-lead kanye nokuhlela ukuhlanganiswa ukuze ibhodi lakhelwe inqubo yokukhiqiza yangempela ezongena kuyo.

Amabhodi anzima e-BGA afanelwe ukubuyekezwa kokwenziwa kanye nokuhlanganiswa okuhlangene

Ama-BGA amakhulu, amaphakheji e-fine-pitch, namabhodi wamandla anezingqimba eziningi angaguqula umehluko omncane we-warpage ube ukulahlekelwa kwesivuno sangempela. Uma umkhiqizo uhlanganisa lezo zingozi, isinqumo sezinto ezibonakalayo kufanele sibhalwe phansi kanye nezibikezelo zenqubo yokuhlanganisa, hhayi ukuphathwa ngokwazo.

Indlela i-Highleap Ebuyekeza Ngayo Ukuvunyelwa Kwezinto Ezibalulekile kanye Nokuphinda Ama-oda

Ukuphindaphinda kuncike kuphakheji yamadokhumenti

Izakhiwo ze-High Tg FR4 eziqine kakhulu yilezo ezihamba phambili ekukhiqizweni okuphindaphindiwe ngencazelo yezinto ezizinzile, izinto ezilinganayo ezivunyiwe, kanye nerekhodi lokukhiqiza elingasetshenziswa kabusha. Uma iphrojekthi ishiywe ku-“Tg 170 noma efanayo,” i-oda elilandelayo livame ukuvula kabusha imibuzo efanayo.

Ngakho-ke i-Highleap itusa ukukhiya umndeni we-laminate, isimo sethusi, ukujiya kwe-stackup, kanye nanoma yiziphi izibikezelo zokuhlanganiswa okukhethekile uma ukwakhiwa kwe-pilot sekuqinisekisiwe.

Izinqumo ezinhle zokuthola imithombo zinciphisa ukuphazamiseka kobunjiniyela besikhathi esizayo

Abakhiqizi abangcono kakhulu abagcini nje ngokuthi yebo ekubizeni okubalulekile. Basiza ekucaciseni ukuthi ngabe ukubiza kuyadingeka yini ngokobuchwepheshe, ukuthi kushintsha kanjani izindleko nesikhathi sokuhola, nokuthi yini okufanele ilawulwe uma ibhodi liqala ukunikezwa njalo.

Okufanele Ukuthumele Ukuze Uthole Isilinganiso Esiphezulu Se-FR4

I-RFQ ewusizo kufanele ixhumanise izidingo zezinto zokwakha, zokwenziwa, kanye nezokuhlanganiswa

• I-Gerber noma i-ODB++, amafayela okubhoboza, kanye nenani lezingqimba
• Uhlu lwe-Target Tg noma lwe-laminate oluvunyiwe
• Izisindo zethusi, ubukhulu bebhodi, kanye nokuphela kwendawo
• Noma yiliphi iphakheji ezwela ukugoba noma inothi le-BGA
• Isikophu sokuhlangana esingenalo i-lead uma ibhodi lizokwakhiwa njenge-PCBA
• Ubuningi, inhloso yokulethwa, kanye nezidingo zemibhalo

Lokho kunikeza i-Highleap ulwazi olwanele lokunquma ukuthi ukuthuthukiswa kwezinto ezibonakalayo kufanelekile yini nokuthi kuthinta kanjani indlela yokukhiqiza.

Imibuzo Evame Ukubuzwa

Ingabe i-High Tg FR4 iyadingeka njalo ekuhlanganisweni okungenalo i-lead?

Cha. Kuncike kusayizi webhodi, ibhalansi yethusi, ingxube yephakheji, ukuvezwa kokugeleza kabusha, kanye nokuthembeka okuqondiwe. Amanye amabhodi ahlangana kahle ku-FR4 ejwayelekile, kanti amanye ayazuza ekuthuthukisweni.

Ingabe i-Tg ephezulu isho njalo ibhodi elingcono?

Cha. I-Tg ephezulu iyasiza kuphela uma ibhekana nenkinga yangempela yokukhiqiza noma yokwethembeka. Ngaphandle kwalokho, ingangeza izindleko ngaphandle kokwengeza ukusebenza okuwusizo.

Ingabe i-Highleap ingasiza ekukhetheni phakathi kwezinto eziningana ezivunyiwe ze-High Tg?

Yebo. Singabuyekeza uhlelo lokusebenza, i-stackup, kanye nendlela yokuhlanganisa ukuze sinciphise ukukhetha kube yimindeni yezinto ezibonakalayo ezifanelana nezidingo zangempela zomkhiqizo.
