Description
516 139 2 längdled vid användning av keramiksubstrat eftersom keramik har en relativt dålig värmeledningsförmåga. Vid alltför höga temperaturer skulle transistorer i komponenterna kunna ta skada på grund av keramiksubstratets dåliga värmeledningsförmåga.
REDOGÖRELSE FÖR UPPFINNINGEN För att en komponent såsom ett chip monterat på ett keramiskt substrat anslutet till en bärare såsom ett mönsterkort ej skall ta skada på grund av keramikens begränsande värmeledningsförmåga har chipet anslutits direkt till mösterkortet med ett tunt skikt, vilket ger den absolut kortaste vägen till mönsterkortet. En direkt anslutning av chipet till mönsterkortet kan åstadkommas genom att höjden på chipet som är kritiskt har som inlödd väsentligen samma bygghöjd som anslutningarna och att chipets baksida limmas eller löds med ett tunt skikt direkt mot mönsterkortet. Om chipet förses med en baksidesmetallisering och förbindningen mellan chipets baksida och jordplanet på mönsterkortet görs elektriskt ledande erhålles samtidigt en substratjordning av godtagbart slag.
Uppfinningen kommer nu att beskrivas närmare med hjälp av föredragna utföringsformer och med hänvisning till bifogade figurblad.
FIGURBESKRIVNING Figur l visar ett chip förbundet med ett substrat monterat på en bärare enligt känd teknik.
Figur 2 visar ett chip förbundet med ett substrat monterat på och anslutet till en bärare enligt uppfinningen.
Figur 3 visar ett chip förbundet med ett substrat monterat på och anslutet till ett kylelement i en bärare enligt uppfinningen. 516 139 3 Fönx-:DRAGNA UTFöRINGsr-ommn Vid stora krav pà ett kompakt byggsätt sàsom vid framtagning av komponenter speciellt framtagna för att passa i telefoner eller andra likartade tillämpningar har en ny typ av moduler framtagits, där diskreta komponenter/chip 6 har monterats pà undersidan av ett bärarsubstrat 7 av flerlagerskeramik mellan detta och ett mönsterkort 8 och i kontakt med mönsterkortet.
Anslutningarna mellan substratet och mönsterkortet utgörs i detta fall även av kulor 9 av ett högtemperatursmältande lod.
Kulorna fungerar här som elektriska anslutningar och som mekaniska distanser genom att vara nagot större än samtliga övriga diskreta komponenter pà substratets undersida. Precis under det chip, som är monterat under substratet, kan finnas ett jordplan 10 pà mönsterkortet som tillsammans med chipets eget jordplan kommer att elektriskt skärma känsliga delar pà chipet. För att förbättra chipets termiska och elektriska egenskaper har chipet anslutits direkt till mönsterkortet med ett ledande tunt skikt ll pà grund av keramikens begränsade substratet. till anslutning av chipet kan àstadkommas genom att anpassa höjden Detta ger den absolut direkt värmeledningsförmàga i kortaste termiska vägen nönsterkortet. En pà det eller de chip som skulle kunna vara kritiska, sà att de inlödda chipen har nästan samma bygghöjd som kulorna och sedan limma eller löda fast chipets baksida. med ett- tunt ledande skikt direkt mot mönsterkortet. Om chipet förses med mellan chipets elektriskt baksidesmetallisering och förbindningen baksida och ledande kan samtidigt erhållas en bra substratjordning av jordplanet pa mönsterkortet görs chipet. Med baksidesmetallisering pà chipet/chipen 6 och en ledande förbindning ll till mönsterkortet 8 kan specifika kylelement 12 pà eller i mönsterkortet direktanslutas till chipet/chipen för deras kylning. 4 Kontakteringen mellan chip och mönsterkort skulle kunna tänkas ske pà i huvudsak två sätt antingen genom limning eller lödning.
I samband med inlödning av modulen kan genom introducering av några extra process steg chipet limmmas fast, efter det att lodpasta har påförts mönsterkortet med exempelvis tryckning och ett lim har dispenserats på mönsterkortet, där chipet sedan skall hamna. Limmet kan lämpligen vara av sådan art att det härdar i samband med omsmältningsprocessen. För att enbart få termisk kontakt mellan chip och nbnsterkort krävs ingen elektriskt ledande baksideskontakt på chipet. Om det samtidigt vill åstadkommas en bra substratjordning av kontakt med ett chipet krävs dock en baksideskontakt i ledande lim.
Med lödning kan chipet anslutas till mönsterkortet utan att ytterligare process steg behöver införas vid inlödning av dock att lödbar till så att chipet inte chipet. Det krävs chipet har en baksideskontakt och att chipet är fixerat keramiksubstratet med en underfyllnad, förflyttas sitt kallade riskerar att från läge då kulor av lågsmältande lod så flipchip-bumpar samtidigt omsmälts. Inlödningen innebär i sig en mycket enkel process eftersom ett jordplan redan existerar under chipet/chipen.
Det enda som skulle behövas vore att en öppning görs i den skyddslack som finns på det område som befinner sig under chipet och att en lodpasta påföres även där.
Uppfinningen är naturligtvis inte begränsad till de ovan beskrivna och de på figurbladet visade utföringsformerna, utan kan modifieras inom ramen för de bifogade patentkraven.
