2025 Productoverzicht en Marktrelevantie voor Pakistan

Silicon carbide (SiC) power device packaging and multiphysics thermal simulation platforms shorten the path from concept to qualified hardware for UPS, VFD, rectifiers, renewables, and EV fast chargers. By co-optimizing package layout, materials, and cooling—then verifying them in virtual prototypes—engineers can reach >98% system efficiency, higher switching frequencies (50–100 kHz), and robust reliability under Pakistan’s hot, dusty, and grid-volatile conditions.

Waarom het ertoe doet in 2025:

• Speed to value: Industrial parks in Karachi, Lahore, and Faisalabad require fast deployment. Digital twins and parameterized package libraries cut prototype spins by 30–50%.
• Reliability in harsh environments: SSiC heat spreaders, Si3N4 DBC, Ag-sinter die attach, and high‑CMTI driver layouts are validated against thermal cycling, vibration, and contamination risks.
• System efficiency: Reduced parasitics, optimized thermal paths, and low‑inductance busbars support >98% conversion efficiency, lowering OPEX and cooling costs in PKR.
• Compliance by design: Early EMI, creepage/clearance, and surge simulations de-risk site acceptance tests (SAT) and utility approvals.

Sicarb Tech offers a complete stack: advanced packaging for SiC MOSFETs/SBDs (discretes, half/full-bridge modules), laminated busbars, R‑SiC/SSiC/RBSiC/SiSiC heat spreaders, and a validated multiphysics simulation workflow (electro‑thermal‑mechanical‑EMI). Backed by the Chinese Academy of Sciences and 10+ years of SiC manufacturing, we enable rapid, localized prototyping for Pakistan’s critical power projects.
