Metal conductive paste for LTCC


Our development priorities

We have developed and manufactured conductive paste for car and communication devices. Nowadays all devices have become smaller and smaller so the electrodes have become finer or thinner.
Very little difference in electrode materials often produce variable results from very little difference. We handle them with flexibility and knowledge and technique.


Development priorities

Point LTCC

LTCC is the abbreviation for Low Temperature Co-fired Ceramics. It is made by mixing alumina and glass compound to form a green sheet. LTCC enables sintering at temperature as low as or less than 1000℃ so that Ag or Cu can be adopted as the conductor, making co-fire possible after laminating the conductor and green sheets, it also miniatures devices by low resistance and high density of substrates so that LTCC beckons to be used for high frequency devices.

Features

- Fine-line printability

Line/Space 20/20 by screen-printing

- Paste shrinkage behavior control

it prevents warps and cracks at sintering and minimizes the proportion of damage.

- High heat resistant


1. Fine lines by screen-printing

It makes no open circuit or short circuit when screen-printing in L/S=20/20, 30/30, 40/40.

Fine lines by screen-printing
2. Shrinkage behavior control

Shrinkage behavior becomes under control by adding additives and our paste shows good match with a variety of green sheets.


3. High Heat-Resistance(with Fine-Line printability)

TMA (Thermal Mechanical Analysis) result of silver paste (No additives). It starts shrinking at higher temperature and still keeps fine-line printability.
