Prezentare generală a produsului și relevanța pe piața din 2025
Il test di funzionamento e le apparecchiature di test automatizzate (ATE) per dispositivi in carburo di silicio (SiC) forniscono gli ambienti di stress ad alta temperatura e alta tensione necessari per lo screening dei guasti nella fase iniziale e per verificare la durata in condizioni difficili. Rispetto al silicio tradizionale, la maggiore rigidità dielettrica e le elevate temperature di giunzione del SiC richiedono forni specializzati, dispositivi di stress di potenza, unità di misurazione parametriche e automazione conforme alla sicurezza. Le piattaforme di burn-in/ATE di Sicarb Tech qualificano MOSFET SiC, diodi Schottky, moduli di potenza e stadi di potenza integrati a 175–200°C, simulando lo stress del mondo reale nei settori tessile, cementizio del Pakistan, açoe settori critici per i dati.
Perché è importante per il Pakistan nel 2025:
- Le strutture subiscono temperature ambiente fino a 45°C e frequenti cali/picchi di tensione; i dispositivi devono essere schermati per robustezza prima dell'implementazione.
- UPS, VFD, inverter FV e BESS richiedono un'affidabilità prevedibile per ridurre OPEX ed evitare interruzioni impreviste.
- La capacità di qualifica localizzata riduce i tempi di consegna e la dipendenza dalle importazioni, supportando implementazioni più rapide per la modernizzazione industriale e l'economia digitale.
- Gli obiettivi ESG e di efficienza energetica amplificano la necessità di piattaforme SiC a lunga durata e ad alta efficienza, comprovate attraverso rigorosi test di funzionamento e test di affidabilità automatizzati.
Sicarb Tech offre sistemi di burn-in chiavi in mano: HTRB, HTGB, power cycling, stress di commutazione dinamica e ATE parametrico automatizzato con registrazione e analisi dei dati. I sistemi sono adattabili al packaging basato su RBSiC/SSiC, garantendo percorsi termici realistici durante lo stress.
