Company Introduction

Rumien Inc. provides semiconductor test sockets and pitch converter solutions based on precision glass micro-fabrication and RDL 
technology. We offer customized designs and precision manufacturing for products that ensure signal integrity and cost 
competitiveness.

Introduction of item

1. Rumien Socket(Glass Test Socket)

Based on a glass substrate, it supports ultra-fine pitch with excellent precision, minimizes electrical signal loss, and enhances high-
frequency response, providing a stable testing environment.

2. Rumien RDL HPC(Glass RDL Hybrid Pitch Converter)

Applies RDL redistribution on a glass substrate with a hybrid bonding structure to PCB, enabling fan-out from minimum pitches above 
100µm to 400µm and redistribution at 400µm pitch. Provides excellent signal integrity and cost competitiveness for advanced 
packaging 
tests.
