Copper paste is a relatively safe colloid dispersed by nano-copper powder. If ingested, it will be poisonous because it will Reacts with things in the stomach, causing heavy metal poisoning.

    Which conductive copper ink or conductive silver paste is more suitable for use on PCB boards?

    First of all, if we consider the electrical conductivity as well as the thermal conductivity, conductive silver paste is better than conductive copper paste, especially after curing, the overall resistance offered by silver is tens or even hundreds of times lower when compared to that of copper, and after curing, the effect of silver paste on the stability is much more when compared to that of copper paste. Even when it is cured for a long time, it will have no effect on the conductivity. However, it will be easily oxidized for a long time, which will have a prominent effect on the conductivity. Therefore, conductive silver paste is more suitable than conductive copper ink. Used on the PCB board.

    What is the role of copper paste sintering?

    There are two functions of copper ink sintering. If we talk about the first one, then it is the removal the organic carrier in the drying film, which is removed under the phenomenon of the sintering furnace smoke. The other is that the glass in the paste of copper can be completely melted and bonded with the copper powder of the metal, thereby promoting the mutual penetration and bonding that is present among the copper powder, or between the copper powder and the body, and is the temperature The faster the decrease, the higher the overall viscosity of the glass will form a chain network structure between the film layers, and the copper film can be formed, which has the advantages of conductivity, solder resistance and adhesion.

    Under normal circumstances, copper slurry sintering process is performed under the protection of nitrogen. The general sintering system includes heating rate, sintering temperature, cooling rate and so on.

    How to dilute the solderable conductive copper paste when it dries?

    If the solderable conductive copper ink dries, we maliciously use a special thinner, but it should be kept in consideration that the overall amount should not exceed 5%. Because the viscosity of the system is generally sensitive to the diluent, a small amount should be added for each test in order to carry out a step-by-step experiment, and it should be used up in time after opening the lid.
