Flexible PCB Manufacturers —
With no in-house fabrication, Growth operates independently and utilizes a network of trusted production partners. This model allows them to deliver a wide array of materials and support agile response to client demands.
Growth’s artwork design team consists entirely of engineers with hands-on experience in hardware development. This means they can integrate considerations such as electrical performance (noise, thermal, EMC), manufacturability, and cost—right from the layout phase.
Thanks to their deep understanding of both circuit design and PCB layout, they effectively translate design intent into high-performance FPCs. Their process emphasizes: Collaborative communication at the engineer level; Accurate performance from the first prototype; Efficient design requiring minimal iteration.
Growth Inc. has experience working with major manufacturers, supporting all stages of hardware development. Services include:
・Artwork design
・High-frequency PCB fabrication
・Circuit design support
・Bare-die mounting
