Bonding Agents in Sintering Two or more sintered pieces can be bonded together by sintering of a bonding agent. The bonding agent is placed between two surfaces of the pieces. The pieces are then consolidated during a sintering cycle (while applying pressure) in which they are joined by solid state diffusion of the bonding agent’s particles.

Silver can be a suitable material for making a sintering paste for bonding semiconductor chips. This sintering paste will contain silver particles having average particle size of 0.1 to 2.0 μm and an organic silver complex solution kneaded together into a slurry state. The organic silver complex solution can contain a liquid fatty acid silver salt compound, a solid fatty acid silver salt dissolved in an organic solvent having a boiling point of 150°C. The concentration of carbon, hydrogen, and oxygen, and a silver content is 30 wt% or more. The process of bonding is showing in the image below. Refer to this patent for more information. What is the composition of a low temperature sintered ceramic bonding agent for diamonds? A low-temperature sintered bonding agent for diamond includes silica solution 30-35 parts, bismuth oxide 45-50 parts, boric acid 5-7 parts, and an additive made of 5-20 parts. The solid content of silica solution is 5-15wt%. The vitrified bond is environmentally protective and its preparation process is pollution-free. Fusing point is very low at 500°C. The bonding agent has strong and excellent mechanical performance. The bonding agent has excellent adhesion strength and good skive mechanical property. Refer to this patent for more information. What sintering material can be used for packaging quartz crystal? Sintering silver paste can be used for packaging quartz crystals. The method comprises attaching a quartz crystal to a package substrate using silver paste layers. The silver paste layers are sintered in a substantially oxygen-free atmosphere. The sintering is done such that the quartz crystal exhibits a positive drift in resonance frequency of the quartz crystal over time. This process can also improve the frequency accuracy of the quartz crystal. Refer to this patent for more information.
