Benefits of K2: Reducing initial costs of flexible circuit boards.

Mold cost 0 yen! Cut initial costs to manufacture flexible substrates cheaply and quickly!

At K2, we do not create molds or Thomson molds (Victoria type) for small lot production of flexible printed circuits, allowing us to respond to generally time-consuming flexible circuit manufacturing with short lead times. Since there are no costs for creating molds, we can significantly reduce the initial costs, making our prices attractive. Additionally, this method allows for individual correction of each circuit board, which is a benefit for high quality. 【Features】 ■ No mold costs for flexible printed circuits ■ Short lead times ■ High quality *For more details, please refer to the PDF document or feel free to contact us.

Benefits of K2: More cost-effective medium-lot production of flexibles.

Providing low-cost medium-lot products unsuitable for both prototype manufacturers and mass production manufacturers!

We offer proposals to reduce initial costs by using laser processing for the prototyping of flexible substrates. However, when it comes to medium-sized production runs, it is more cost-effective to create molds. For large quantities that cannot be handled by prototyping manufacturers, and where the initial costs become too high for mass production manufacturers, please leave it to us. We can provide it at a low price. *For more details, please refer to the PDF document or feel free to contact us.
