Thick Film Firing Mesh Belt Furnace Ceramic Substrates 900C 42kW 7 Zones LTCC

The SLK thick film firing mesh belt furnace is a high precision conveyor furnace developed for firing thick film conductor, resistor and dielectric pastes onto ceramic substrates, as well as for co firing low temperature co fired ceramic multilayer structures. A 300mm wide mesh belt carries the substrates through seven independently controlled temperature zones to a working temperature of 900C, with a maximum temperature of 1050C available for the more demanding firing profiles. Temperature uniformity of plusmn 3C across the constant temperature zone ensures reproducible sheet resistance and adhesion, which are decisive quality parameters in thick film and LTCC production. The furnace is clean, stable and designed to run continuously with minimal drift.

• Seven Zone Precision Firing: Seven separate heating zones with individual K type thermocouples and PID auto tuning controllers deliver the carefully shaped firing profile that thick film and LTCC pastes require for correct densification and adhesion.
• 900C Stable Firing Zone: A rated firing temperature of 900C with uniformity of plusmn 3C ensures consistent resistivity, dielectric properties and bond strength from the first substrate to the last.
• Clean Atmosphere Firing: A multi path compressed air circuit with individual flow meters maintains a clean oxidizing atmosphere and removes organic vehicle vapors through dedicated exhaust chimneys.
• Gentle Warm Up Profile: The multi zone control lets operators program a slow binder burn out and paste decomposition ramp before the firing peak, preventing blistering, delamination and pinhole defects.
• Repeatable Continuous Output: The inverter driven belt from 30mm to 200mm per minute and stable thermal profile provide repeatable throughput for high volume substrate and circuit production.
• Full Process Monitoring: The PLC and touch screen system records temperature data, stores firing recipes and supports MES integration so that every fired lot can be traced and documented.

This thick film firing mesh belt furnace is used for firing thick film conductor, resistor and dielectric inks on alumina and other ceramic substrates, as well as for co firing LTCC multilayer modules, glass passivation layers and ceramic metal seals. It supports the production of hybrid microcircuits, sensor elements, resistor networks, power modules and multilayer ceramic capacitors in the pre sintering stages. Electronics and sensor manufacturers rely on its precise multi zone profile and clean atmosphere to achieve stable electrical properties and strong paste adhesion, making it suited both to prototype development and to continuous high volume firing in modern electronics manufacturing.

The furnace is assembled and fully temperature profiled in our works before shipment to confirm the uniformity and stability of every zone. Each unit is delivered with inspection certificates, component certificates, a complete technical document set and spare heating modules, thermocouples and solid state relays. Careful wooden case packing with moisture protection safeguards the precise refractory construction during ocean transport. Our engineers provide on site installation and commissioning support and help tune the firing profile to your specific pastes and substrates, and the furnace is backed by a defined warranty and reliable long term service.

Please provide the substrate material and size, the paste system, the required firing profile and the target throughput, and we will confirm the number of zones, the heating power and the gas circuit configuration. We will then prepare a technical proposal, general arrangement drawing and commercial quotation. Minimum order quantity is one unit, payment terms are T/T, and the standard lead time is 75 to 100 days. Contact our technical team today for a firing solution built around your products.
