What is Ventec VT-47?
Ventec VT-47 is a halogen-free, high-Tg FR-4 alternative specifically developed for European automotive OEM requirements. It delivers standard FR-4-class electrical performance while eliminating brominated flame retardants, meeting both EU environmental directives and automotive industry material declarations.
European automotive Tier 1 suppliers (Bosch, Continental, Valeo, ZF) maintain strict material compliance requirements including GADSL (Global Automotive Declarable Substance List) and IMDS (International Material Data System) reporting. VT-47 provides full IMDS data sheets and GADSL compliance declarations, simplifying material qualification for automotive programs.
Ventec's European headquarters provides regional technical support, local inventory, and IATF 16949 quality management system certification — the specific requirements that European automotive supply chain managers validate during supplier audits.

| CTE z-axis | ~45 ppm/C | Controlled for automotive reliability requirements. |
| Flammability | UL 94 V-0 (halogen-free) | Flame retardant without halogens. |
| Halogen content | <900 ppm (total) | Meets IEC 61249-2-21 halogen-free definition. |
| Moisture absorption | ~0.12% | Standard for automotive operating environments. |
| CAF resistance | High | Conductive anodic filament resistance for automotive spacing. |
Why European Automotive Specifies VT-47
European automotive OEMs enforce material substance restrictions beyond RoHS requirements. The GADSL (Global Automotive Declarable Substance List) requires full material composition disclosure, and many OEMs have declared halogen-free as a design requirement for new programs. VT-47 satisfies both the technical performance and material compliance requirements simultaneously.
Conductive Anodic Filament (CAF) resistance is critical for automotive PCBs operating at elevated temperature and humidity over 10-15 year vehicle lifetimes. VT-47 achieves enhanced CAF resistance through optimized glass-resin interface chemistry, preventing the electrochemical migration that causes field failures in standard FR-4 under automotive conditions.
European supply chain qualification audits verify material traceability, quality management systems (IATF 16949), and environmental compliance documentation. Ventec's European-certified operations provide these documents without the complexity of qualifying Asian sources for European automotive programs.

VT-47 Design for Automotive Applications
VT-47 processes identically to standard high-Tg FR-4 — no fabrication changes required. Drill parameters, lamination profiles, surface finishes, and solder mask systems remain the same. The transition from halogenated FR-4 to VT-47 is transparent to fabrication.
For automotive reliability, maintain IPC Class 3 design rules: minimum 4mil trace/space, 10mil pad-to-trace clearance, and via aspect ratios below 8:1. These conservative rules combined with VT-47's CAF resistance ensure 15+ year field reliability under automotive thermal and humidity cycling.
