Prominent Technology

Own Know-how & Skills

CDK manufactures products with high quality and reliability by own know-how and design skills, which have been cultivated in closely cooperating with major manufacturers. For now, we are moving forward as a manufacturer covering from design, development, and production consistently.

Hollow Packaging

Hollow Packaging

CDK's original hollow packaging technology to produce an ideal air structure for the RF signal at around the semiconductor die. Due to this, ultra-low noise HEMT which receives radio waves of satellite broadcasting can amplify waves with high efficiency. CDK has high-throughput manufacturing line, and have manufactured record 50M pcs in the past.

RF Testing

RF Testing

In semiconductor devices for wireless communication products, variety performance test is performed. Moreover, RF test result is very sensitive to test environment. CDK has own know-how, so we can provide to high-throughput RF testing for mass product with high accuracy.

Die attach (Power Amplifier)

High power amplifier for sending signal is used to base station of smartphone. CDK was automatized die attach process for power FET such as GaN and LDMOS. As a result, it can be produced in a stable low-cost high power amplifier.
