Frequently Asked Questions
What are the key differences between BMC and DMC materials?
BMC (Bulk Molding Compound) offers excellent dimensional stability and mechanical strength ideal for precision components. DMC (Dough Molding Compound) provides superior surface finish and extended thermal aging resistance for long-life applications. Both are thermoset composites significantly outperforming thermoplastics in electrical and thermal properties. Material selection depends on specific electrical requirements, operating temperature, and mechanical loads.
How do you ensure batch-to-batch consistency in production?
Our quality system implements Statistical Process Control monitoring critical molding parameters including temperature, pressure, and cure time. Each production batch undergoes first article inspection with dimensional measurement and electrical testing. In-process sampling with automated testing equipment validates consistency. Process capability studies maintain Cpk >1.67 on critical dimensions ensuring reliable assembly fit across production volumes.
Do you support sample prototyping and testing?
Yes, complete prototyping services include soft tooling for rapid sample production, dimensional inspection, electrical property testing (dielectric strength, insulation resistance), and thermal performance validation. Sample development typically requires 2-3 weeks. We provide comprehensive test reports supporting customer qualification and design validation before production tooling investment.
What are typical lead times for samples and production?
Sample development with soft tooling requires 2-3 weeks including molding and testing. Production tooling fabrication ranges 4-6 weeks depending on complexity. Volume production lead time is typically 3-4 weeks after tooling approval. Expedited options available for urgent programs with advance planning and engineering coordination.
Do you provide quality certifications and test reports?
Complete documentation packages include material certifications, dimensional inspection reports with CMM data, electrical test results (dielectric strength, insulation resistance, tracking index), and thermal aging validation. We support customer-specific requirements including PPAP documentation, third-party testing coordination, and compliance certificates for UL, CE, and international standards.
