Should we conduct a complete test or ten thousand process tests on conductive silver adhesive

Everyone knows about process testing, so let me explain the concept of complete testing first.

The International Metalization Conference has been held for 10 sessions, with dozens of contact mechanism reports each year, mainly from research institutes such as Fraunhofer/ECN, and of course, reports from companies such as DuPont and Heraeus, but still mainly from Fraunhofer. Fu himself doesn't do itsizeIt can also be said that he did not have any profound research on pulp products, and even the samples he tested were provided by DuPont. So why did he convene experts from all over the world to the Rhine River to give a report and explain the mechanism??!!

If you carefully read Fu's report, you will find that he started to change different sintering parameters when he received the sample, and then cut the sintered pieces horizontally and vertically from the micrometer level, and analyzed the composition of each layer, especially the microstructure of the interface, in endless detail. All my thoughts can be said to be based on Fu's report and the endless detailed and clear electron microscope photos. I know it would take a lot of manpower and resources to actually make these photos, but I got them all for free.

Although Fu only conducted one experiment, what he did was a complete experiment, a long experiment. Although they were unable to produce the samples themselves, they made changes to the key elements, followed by sintering parameters, and finally microstructure analysis. Based on these experimental phenomena and data, they activated their strong knowledge background in semiconductor, metal, inorganic, and organic materials to start a powerful analysis, and then proposed a mechanism to explain it. This is their work.

It is not difficult to understand the mechanism, only a complete long experiment is needed. But it can be confirmed that the vast majority of companies, except for DuPont, have not repeated Fu's experiment, despite conducting tens of thousands of tests.

Du's three-dimensional research and development from the Academia Sinica to the actual engineering center helped him understand the mechanism, establish the architecture, form a patent pool, and beat all other companies. Why can it be hammered? It's obvious that the architecture was established by him, and everyone is within his architecture. This is the power of originality, this is the power of understanding mechanisms and building structures!!

By this point, I know many friends have already said that Du is so powerful that he hasn't been sold yet, even though he is still using his patent power. It must be said that selling is a commercial act, not a technical act. Business is the result of multi factor competition, such as profit and price.

Du has also conducted numerous experiments. Although it is simple to understand the mechanism, there are many process tests required for a product to be formed. This is the most labor-intensive stage, and of course, it is our strength. Not to mention the slurry, it's the solar energy itself. Look at how Tongwei Energy has transitioned from making feed to solar energy and achieved good efficiency. You can talk to them in the workshop and see how they squeeze the limits of the process and explore its potential to improve efficiency. Because none of the original technologies such as polycrystalline single crystal PeRc are ours, and the original architecture is Western.

The West indeed values research and development, always pursuing innovation and breakthroughs, while relatively lacking in exploring the limits of technology. And technology is indeed the final stage of product implementation, so besides many things that we have overcome in the West through speed and the exploration of technological limits, solar energy is the best example.

After understanding the complete long test and ten thousand process tests, it is obvious that this is not a multiple-choice question, but rather a combination of the two. The process experiment competition is about manpower and material resources, and in the end, it may rely on strong material resources to win, but it is very hard and like Lenovo, it cannot win respect!!

If there are new discoveries in the mechanism experiment by combining the two, it will be a new structure reopening the world!!!
