Features of Flexible PCBs by K2 Inc.
Key Features of Flexible PCBs
Diverse FPC Production with In-House Facilities
With a wide array of equipment dedicated to PCB manufacturing, K2 can produce a full range of flexible PCBs including single-sided, double-sided, and multilayer boards. They also support rigid-flex PCB prototyping, which is typically difficult to handle through conventional processes.
Short Lead Times with Integrated In-House Processes
From copper and gold plating to final processing, all stages are managed in-house. This ensures fast turnaround even for medium-lot orders. Their proprietary production control system prevents omissions in process tracking and ensures accurate delivery schedules.
No Initial Tooling or Mold Costs – Significant Cost Reduction
K2 does not charge initial setup fees for flexible PCB production. Mold costs for coverlay or outline processing (including Thomson molds) are also eliminated by using NC machines, enabling major cost savings.
