Isici sokupakishwa kwe-BGA

Kuyini ukupakishwa kwe-BGA

Iphakheji ye-BGA ibhekisela ephaketheni lapho amabhola e-solder afakwe ngemuva kwephakheji (bheka Umfanekiso 1). I-BGA inezici ezilandelayo uma iqhathaniswa ne-QFP.

Izici zephakheji ye-BGA uma kuqhathaniswa ne-QFP:
- Iphakheji ye-BGA ngokuvamile incane kune-LQFP enani elifanayo lamaphini.
- Iphakheji ye-BGA ngokuvamile inamaphinikhodi amaningi kune-LQFP yosayizi wephakheji ofanayo.
- Amaphakheji e-BGA angcono ekuqedeni ukushisa njengoba anokumelana okuphansi kwe-thermal kunamaphakheji e-QFP njengoba kunendlela engcono yokukhipha ukushisa ngokusebenzisa i-substrate.
- Amaphakheji e-BGA angama-impedance aphansi angcono kanye nesivinini sokudlulisela okuphezulu ngoba ubude bephakheji bungafinyezwa nge-miniaturization kanye ne-substrate (interposer) ingaba i-multilayered.
- Amaphakheji e-BGA anohlelo olufanele lwebhola lapho izici zikagesi zicatshangelwa. Kodwa-ke, uma akudingekile ukucabangela izici zikagesi, ibhola lingafakwa noma kuphi.

Qaphela: I-BGA enempahla yephakheji yepulasitiki ibizwa ngokuthi i-PBGA (i-Plastiki BGA). E-Renesas, i-BGA ngokuvamile ibhekisela ku-PBGA.

Example yokuhlelwa kwebhola le-BGA

Njengoba kuboniswe kumfanekiso wesi-2, inani lamasiginali angaxhunywa ku-QFP licishe lilungiswe ngokuhlobene nosayizi wephakheji (Bheka Umfanekiso 2, Ikesi le-QFP), amaphakheji e-BGA angahlukaniswa cishe abe ngamalungiselelo amathathu ebhola.

– Esokuqala yilapho ibhola libekwe endaweni engaphandle yephakheji (Bheka Umfanekiso 2, Ikesi BGA①). Isetshenziswa uma inani lamasiginali lilincane kusayizi wephakheji.

- Okwesibili yilapho ibhola elishisayo libekwe ngokuqondile ngaphansi kwe-chip ngaphezu komjikelezo wangaphandle wephakheji (Bheka Umfanekiso 2, Ikesi BGA②). Yamukelwa lapho ukuchithwa kokushisa kudinga ukucatshangelwa.

- Okwesithathu yilapho amabhola ebekwe endaweni yonke yephakheji ngaphandle kwezikhala (Bheka Umfanekiso 2, Ikesi BGA③). Isetshenziswa uma inani lamasignali likhulu. Ngokuvamile, kunzima kakhulu ukuklama amaphakheji namabhodi ngephakheji elinjalo, futhi kokubili iphakheji kanye nebhodi elingafakwa kulo kungabiza.

Izakhiwo ze-BGA Packaging

Ukumelana nokushisa (Inani elibonisa ubunzima bokudlulisa izinga lokushisa)

Uma kuqhathaniswa ne-QFP, i-BGA ine-advantage yokumelana nokushisa okuphansi ngoba inyusa indlela yokukhipha ukushisa nge-substrate. Ngamanye amazwi, ama-BGA anezici ezingcono zokulahla ukushisa kune-QFP (Bheka Umfanekiso 5).

Njengoba kuboniswe ku-Figure 5, uma kuqhathaniswa ne-QFP, i-BGA inokumelana nokushisa okuphansi kune-QFP ngoba ngaphezu kwendlela yokushisa ukushisa okuvela engxenyeni eholayo kanye ne-resin ekhonjiswe umcibisholo obomvu, ukushisa okukhiqizwa yi-chip ekhonjiswe umcibisholo onsomi kukhishwa ngokuqondile ngaphansi kwe-chip kusuka emthonjeni wokukhiqiza ukushisa ngokusebenzisa i-vias namabhola ephakheji.

Izici zikagesi

Amaphakheji e-BGA angenziwa abe mancane kunamaphakheji anezikhonkwane ezifana namaphakheji e-QFP, angcono ku-impedance ephansi kanye nesivinini esikhulu sokudlulisela (Bheka Umfanekiso 6).

- Uma kuqhathaniswa namaphakheji we-QFP, i-BGA ingafinyeza ubude obuphelele ngaphakathi kwephakheji, ukuze izingxenye ze-inductance nezokumelana zehliswe.

- Ubude bentambo yokubopha kanye nobude bokulandelela ngaphakathi kwephakeji ye-BGA bungafushaniswa ngokuqhubekayo, futhi izingxenye ze-inductance nezokumelana zingehliswa ngokunciphisa usayizi wephakheji we-BGA.

Example: Njengoba i-BGA inganciphisa ukuvinjelwa kokunikezwa kwamandla, kungenzeka ukunciphisa inani lama-bypass capacitor (ngemuva kwalokhu okubizwa ngokuthi i-CC: Chip Capacitor) ekunikezeni amandla futhi kube negalelo ekwehlisweni kwezindleko ze-BOM.

Izinyathelo Ezivamile Zokuqaphela Ekuphatheni Iyunithi Yokucubungula Kakhulu kanye Nemikhiqizo Yeyunithi Yeyunithi Ye-Microcontroller

Amanothi okusetshenziswa alandelayo ayasebenza kuwo wonke amayunithi we-Microprocessing kanye neyunithi yemikhiqizo ye-Microcontroller evela kwa-Renesas. Ukuze uthole amanothi anemininingwane okusetshenziswa emikhiqizweni ehlanganiswe yilo mbhalo, bheka izigaba ezifanele zedokhumenti kanye nanoma yiziphi izibuyekezo zobuchwepheshe ezikhishelwe imikhiqizo.

1. Ukuqapha ngokumelene ne-Electrostatic Discharge (ESD)
   Inkambu kagesi eqinile, lapho ivezwe kudivayisi ye-CMOS, ingabangela ukucekelwa phansi kwe-oxide yesango futhi igcine ithunaza ukusebenza kwedivayisi. Kufanele kuthathwe izinyathelo zokumisa ukukhiqizwa kukagesi omile ngangokunokwenzeka, futhi kuhlakazwe ngokushesha lapho kwenzeka. Ukulawulwa kwemvelo kumele kube ngokwanele. Lapho somile, kufanele kusetshenziswe i-humidifier. Lokhu kunconywa ukugwema ukusebenzisa ama-insulators angakha kalula ugesi omile. Amadivaysi e-semiconductor kufanele agcinwe futhi ahanjiswe esitsheni esingaguquguquki, isikhwama sokuvikela esimile noma impahla yokuqondisa. Wonke amathuluzi okuhlola nawokulinganisa okuhlanganisa amabhentshi okusebenza kanye nephansi kufanele kubekwe phansi. Umsebenzisi kufanele futhi amiswe phansi kusetshenziswa ibhande lasesihlakaleni. Amadivaysi e-semiconductor akufanele athintwe ngezandla ezingenalutho. Izinyathelo ezifanayo kufanele zithathwe kumabhodi esekethe aphrintiwe anamadivayisi afakwe ku-semiconductor.
2. Icubungula ngokuvula amandla
   Isimo somkhiqizo asichazwanga ngesikhathi lapho kunikezwa amandla. Izimo zamasekhethi angaphakathi ku-LSI azinqunyelwe futhi izimo zezilungiselelo zerejista namaphinikhodi azichazwanga ngesikhathi lapho kunikezwa amandla. Kumkhiqizo oqediwe lapho isignali yokusetha kabusha isetshenziswa kuphinikhodi yokusetha kabusha yangaphandle, izimo zamaphini aziqinisekiswa kusukela ngesikhathi lapho amandla anikezwa khona kuze kuqedwe inqubo yokusetha kabusha. Ngendlela efanayo, izimo zamaphini kumkhiqizo osethwe kabusha umsebenzi wokusetha kabusha amandla e-chip aziqinisekisiwe kusukela ngesikhathi lapho amandla anikezwa khona kuze kube yilapho amandla efika ezingeni lapho ukusetha kabusha kucacisiwe.
3. Okokufaka kwesignali ngesikhathi sokucishwa kwamandla
   Ungafaki amasignali noma ugesi wokudonsa we-I/O ngenkathi idivayisi ivaliwe. Umjovo wamanje ophumela ekufakweni kwesignali enjalo noma amandla okudonsa e-I/O angase abangele ukungasebenzi kanye namandla angavamile adlula kudivayisi ngalesi sikhathi angabangela ukuwohloka kwezinto zangaphakathi. Landela umhlahlandlela wesignali yokokufaka ngesikhathi sokucisha amandla njengoba kuchazwe kumadokhumenti womkhiqizo wakho.
4. Ukuphatha izikhonkwane ezingasetshenzisiwe
   Bamba izikhonkwane ezingasetshenzisiwe ngokuhambisana neziqondiso ezinikezwe ngaphansi kokuphathwa kwezikhonkwane ezingasetshenzisiwe kumanuwali. Izikhonkwane zokufaka zemikhiqizo ye-CMOS zivame ukuba sesimweni sokungasebenzi kahle. Kusebenza ngephinikhodi engasetshenzisiwe esimweni sesekhethi evulekile, umsindo owengeziwe we-electromagnetic ungeniswa eduze kwe-LSI, ukudubula okuhlobene okugeleza kwamanje ngaphakathi, futhi ukungasebenzi kahle kwenzeka ngenxa yokubonwa okungamanga kwesimo sephini njengesignali yokufaka. kwenzeke.
5. Izimpawu zewashi
   Ngemva kokufaka ukusetha kabusha, khulula kuphela umugqa wokusetha kabusha ngemva kokuba isignali yewashi lokusebenza izinzile. Lapho ushintsha isignali yewashi ngesikhathi sokusebenza kohlelo, linda kuze kube yilapho isignali yewashi eliqondiwe izinzile. Uma isignali yewashi ikhiqizwa nge-resonator yangaphandle noma i-oscillator yangaphandle phakathi nokusetha kabusha, qinisekisa ukuthi umugqa wokusetha kabusha ukhululwa kuphela ngemva kokuzinza okuphelele kwesignali yewashi. Ukwengeza, lapho ushintshela kusignali yewashi ekhiqizwe nge-resonator yangaphandle noma i-oscillator yangaphandle ngenkathi ukwenziwa kohlelo kuqhubeka, linda kuze kube yilapho isignali yewashi eliqondiwe izinzile.
6. Voltage-application waveform at input pin
   Ukuhlanekezelwa kwe-Waveform ngenxa yomsindo wokufakwayo noma igagasi elibonisiwe kungase kubangele ukungasebenzi kahle. Uma okokufaka kwedivayisi ye-CMOS kuhlala endaweni ephakathi kwe-Vɪɩ (Ubukhulu.) kanye ne-Vɪʜ (Min.) ngenxa yomsindo, ngokwesiboneloampfuthi, idivayisi ingase ingasebenzi kahle. Qaphela ukuvimbela umsindo oxoxayo ukuthi ungangeni kudivayisi lapho ileveli yokufaka isilungisiwe, kanye nasesikhathini soshintsho lapho ileveli yokokufaka idlula endaweni ephakathi kwe-Vɪɩ (Max.) ne-Vɪʜ (Min.).
