For Low-Temperature Co-fired Ceramics (LTCC) / Ferrite Thin Films

Setter Plates for LTCC and Ferrite Films

This product is an inorganic ceramic fiber board with high porosity, specifically developed for precision sintering processes involving LTCC, ferrite films, and solar silicon wafers. Manufactured from high-purity ceramic fibers using a vacuum-forming process, it features excellent surface flatness, high chemical inertness, and high porosity. Its porous structure facilitates binder burnout and absorption during the sintering of ceramic components, while its lightweight nature makes handling and furnace loading convenient, making it an ideal setter board material for these applications.

Product Features

1. High Surface Flatness

Precision-machined to achieve high flatness, the product provides a smooth, stable support surface for sintering LTCC green tapes, ferrite sheets, and silicon wafers, effectively preventing deformation or warping during the sintering process.

2. High Chemical Inertness

The material exhibits excellent chemical stability; it does not react with LTCC ceramics, ferrite materials, or silicon wafers at high temperatures. It ensures no contamination of the sintered products, thereby preserving their electrical and physical properties.

3. High Porosity for Effective Siphon-based Debinding

With its high porosity, the product facilitates effective siphon-based debinding of ceramic sheets during sintering. It allows for the timely removal of gases and liquid by-products generated from the decomposition of organic binders, ensuring thorough debinding and reducing sintering defects.

4. Lightweight

The product features low density and light weight, making handling and loading/unloading easy. It also reduces the load on kiln supports and improves energy efficiency.

5. Excellent Thermal Stability

The product maintains structural integrity within the LTCC sintering temperature range and offers superior thermal shock resistance, withstanding frequent heating and cooling cycles without cracking.

6. Non-stick and Easy to Separate

The sintered products do not adhere to the setter plate and can be easily separated, thereby boosting production efficiency and reducing the need for post-processing steps.

Frequently Asked Questions (FAQ)

1. What are the benefits of high porosity for LTCC sintering?

High porosity facilitates “wicking” and infiltration during sintering, allowing gaseous and liquid by-products from organic decomposition to be expelled promptly; this results in more thorough binder removal, fewer sintering defects, and a higher product yield.

2. Will the product contaminate the LTCC ceramic material?

No. This material is chemically inert; it does not react with LTCC ceramics at high temperatures, nor does it contaminate the sintered parts, and it maintains stable electrical and physical properties.

3. How is the surface flatness of the product?

Features a precision-finished surface with high flatness, providing stable support for thin ceramic components and effectively preventing deformation and warping during sintering.

4. Is the product suitable for sintering solar silicon wafers?

Yes. The product’s high flatness, chemical inertness, and lightweight nature make it equally suitable for use as a support carrier during the sintering of solar silicon wafers.

5. What are the advantages of the product’s lightweight design?

The boards are lightweight, making them easy to handle, load, and unload. They also impose less load on the kiln furniture supports, helping to save energy and reduce costs.
