Our diamond grinding fluid products are made from ultra-hard diamond micro-powder, which is precision shaped and graded, as the raw material. This is a suspension prepared through special process and chemical reagents. It can be categorized into water-based and oil-based systems, and is also known as diamond fluid in some manufacturing plants.
For diamond grinding fluid used in the precision grinding and thinning process of LED substrates, the single-grain multi-point grinding in the grinding process ensures continuous efficiency. Additionally, the precision-sorted abrasive diamond, free of abnormal large particles and uniformly dispersed, also guarantees no damage to the workpiece surface, thus avoiding the phenomenon of fragments and damaged substrates during the LED substrate thinning process.
This product is suitable for precision processing of substrates like LED sapphire and silicon carbide, as well as for the grinding and polishing of other brittle and hard materials.
The actual product design can be adjusted according to the equipment characteristics of the user's process and the technical requirements of the product.
Product Reference Usage Index
Diamond polishing fluid products are commonly used with single-sided polishing equipment from manufacturers such as NTS, SHUWA, Kemet, Engis, and WSC. In the LED substrate processing technology, customers will rationally select equipment, processes, and corresponding consumables based on their own technology. Generally, the product technical specifications they pay attention to include:
Removal Rate
Material thickness removed per unit time, unit: um/min
Surface Grinding Quality
Surface roughness Ra value (≤ how many nm or A) can be measured, and it can also be visually assessed by the naked eye based on experience, or with the aid of a biological microscope for辅助 observation.
Stability
Two aspects: the variance between bottles within the same batch of products and the variance between different batches.
Overall Assessment
Engage in technical discussions and communicate about delivery schedules, service quality, etc.
