Thick-Film Circuit Paste
I. Product Overview
Thick-film circuit paste (electronic paste) is composed of metal powder, inorganic powder, and organic vehicle (made from polymer solution). Applied to insulating substrates via screen printing or inkjet printing, it forms conductive, resistive, or insulating functional films.
II. Core Processes
1. Paste Preparation (Sample Room)
Organic vehicle: Dissolve organic resin in special solvent.
Mixing & grinding: Weigh raw materials (metal/glass powder), stir with vehicle, and disperse agglomerates via three-roll mill.
Viscosity adjustment & testing: Tune viscosity, inspect physical/functional indicators (fineness, fluidity, conductivity) to meet standards.
2. Printing Process (Printing Room)
Core application: Screen printing (squeegee extrusion transfers paste through screen openings to form circuit patterns).
Key properties: Plasticity (viscosity decreases under force, recovers after printing) and thixotropy (stir well before use).
Essentials: Match paste properties (viscosity, fineness) with equipment parameters (screen mesh, squeegee angle, pressure).
3. Sintering (Sintering Room)
Temperature control: Precise setting of peak temperature, holding time, and annealing (four stages: solvent evaporation → polymer decomposition → glass phase softening → metal phase sintering).
Atmosphere control: Adjust gas flow, balance, and purity to ensure film compactness and performance (avoid defects like bubbles or conductivity loss).
