Ama-PCB e-IC Substrate: Ukuklama Nokukhiqiza

I-PCB ye-substrate ye-IC inikeza isixhumi sikagesi nesomshini phakathi kwephakheji yesekethe ehlanganisiwe kanye nezinga elilandelayo lokuhlanganiswa. Isekela ukuxhumana okuqinile, izindlela zikagesi ezilawulwayo, ukudluliselwa kokushisa, kanye nezindlela zokunamathisela eziqondene nephakheji. Ukuze uthole izinto zokwakha ze-ABF kanye nokuhlanganiswa kwe-substrate , ukucutshungulwa kwephakheji ne-substrate kanye nesixhumi se-PCB-level assembly kudinga izidingo ezihlukene; imizila emibili yokukhiqiza akufanele iphathwe njengengashintshaniswa.

Ngenxa yokuthi lezi zakhiwo zihlobene kakhulu nobuchwepheshe bephakheji, izidingo zokuklama nokukhiqiza kumele zichazwe kahle ngaphambi kokuba kukhethwe indlela yokukhiqiza.

Lokho Okwenziwa yi-IC Substrate PCB

Ama-substrate e-IC asabalalisa kabusha ukuxhumana phakathi kwe-die noma i-package interface kanye nokuxhumana okukhulu kwezinga le-PCB. Kuye ngephakheji, angafaka imigqa emincane, ama-microvia, ama-solder mask-defined pads, izindiza zokubhekisela, kanye nezici zokushisa.

I-substrate iyingxenye yesistimu kagesi. Ukuhlanganiswa kwayo, izinto zokwakha, kanye ne-geometry kungathinta ubuqotho besiginali, ukusatshalaliswa kwamandla, i-warpage, kanye nokusebenza kokushisa.

Izidingo Zomklamo Oqhutshwa Yiphakheji

Qala ngokudweba iphakheji kanye nokucaciswa kokuxhumana. Iphimbo lephedi, imephu yebhola, ukunamathiselwa kwedayi, ubuningi bomzila, ama-impedance target, kanye nendlela yokushisa kunquma ukwakhiwa. Gwema ukuphatha i-IC substrate njenge-PCB ejwayelekile enezingqimba eziningi enobuciko obuncane.

Qopha ukubekezelelana okubalulekile, izindiza zokubhekisela, izidingo ze-impedance, kanye nemigomo yokuhlola ukuze isibuyekezo sokukhiqiza sisekelwe ezidingweni zangempela zephakheji.

Izinto zokwakha kanye nokuqoqwa kwempahla

Ukukhethwa kwezinto ezibonakalayo kucabangela ukuziphatha kwe-dielectric, ukuzinza kobukhulu, ukusebenza komswakama, ukujikeleza kokushisa, kanye nokuhambisana nenqubo yokujoyina. I-stack-up kumele ihlinzeke ngeziteshi zokuhambisa ezisebenzayo ngenkathi ilawula ukujiya kwe-dielectric kanye nokubhaliswa kwayo.

Kumaphakheji esivinini esikhulu noma e-RF, sebenzisa idatha yezinto ezikhethiwe kanye nokuhlaziywa kwe-field-solver ukuqinisekisa i-impedance kunokuthembela ekucabangeni okuqanjiwe.

Imigqa Emihle Nama-Microvia

Ukuxhumana okuqondile kudinga ukuthwebula izithombe okulawulwayo, ukubhoboza noma ukucutshungulwa nge-laser, ukuplata, kanye nokubhaliswa. Isici esincane kunazo zonke kufanele sikhethwe enkambisweni enekhono, eqinisekisiwe futhi sisekelwe yimithetho yokuklama engokoqobo.

Izakhiwo ze-microvia, izilinganiso zesici, kanye nokuxhumeka okuhlanganisiwe noma okuhlanganisiwe kufanele kubuyekezwe ukuze kutholakale ukuthembeka nokuhlolwa ngaphambi kokuba umklamo ukhishwe.

Izinto Okucatshangelwayo Zokuhlanganisa Nokuthembeka

Ukuthamba kwe-substrate, ukuqeda ubuso, ukushiswa kwe-solder, kanye nokwandiswa kokushisa kuthinta ukuhlanganiswa kwephakeji. Ukuhlolwa kungafaka phakathi i-warpage, ukuthembeka kwe-solder-joint, ukujikeleza kokushisa, ukuzwela komswakama, kanye nokusebenza kukagesi ngaphansi kwezimo zokusebenza ezihlosiwe.

Ukuqinisekiswa kwephrothotype kubalulekile ngoba izinguquko ezincane ezintweni ezibonakalayo, i-geometry, noma inqubo yokujoyina zingaba nomthelela obalulekile ekuziphatheni kwephakeji.

Isibuyekezo se-IC Substrate nge-Highleap

I-Highleap Electronics ingabuyekeza ulwazi lwe-substrate ye-IC enikeziwe kanye ne-PCB assembly ukuze ithole ukuthi iyakwazi yini ukwenziwa, imikhawulo ye-component-interface, kanye nokuhlela ukuhlolwa. Ukungenzeka kufanele kuqinisekiswe ngokumelene nesethi yezici ezidingekayo kanye nomthamo wokukhiqiza.

Ukuze uthole isibuyekezo sokwenziwa, cela ikhotheshini ye-PCB enezidingo zokudweba iphakheji, ukuqoqa, umsebenzi wobuciko, i-BOM, kanye nokuqinisekiswa.
