Frequently Asked Questions
A: Our standard lead time for custom cable assembly prototypes is 1 to 2 weeks upon CAD drawing approval. For mass production orders, the standard lead time is 3 to 4 weeks, depending on component availability, custom tooling requirements, and batch quantity.
A: Yes, absolutely. Our engineering team can generate accurate quotes and preliminary CAD drawings based on physical samples, rough hand sketches, pinout diagrams, or component specifications (such as connector part numbers and wire gauges).
A: Yes. We provide First Article Inspection (FAI) samples and functional prototypes for design validation, form-fit-function testing, and electrical performance verification before committing to full-scale manufacturing.
A: We offer flexible global logistics solutions, including express air freight (DHL, FedEx, UPS for rapid sample delivery), air cargo, and sea freight (FCL/LCL). We support flexible Incoterms including EXW, FOB, CIF, DDP, and DDU.
A: Operating advanced automated wire stripping, crimping, and testing equipment, Romtronic maintains a monthly production capacity of over 500,000 units, supporting both high-mix low-volume (HMLV) prototype runs and high-volume mass production.
A: Yes. Our senior engineering team provides complete Design for Manufacturability (DFM) and Design for Assembly (DFA) support. We assist with conductor gauge selection, EMI/RFI shielding strategies, overmold design, and cost-reduction material alternatives.
A: We supply high-reliability interconnect solutions to mission-critical sectors including Medical & Healthcare (ISO 13485 compliant), Automotive & EV Power (IATF 16949 certified), Industrial Automation & Robotics, Telecommunications, and Aerospace electronics.
