8inch 12inch Semi-automatic Semiconductor Wafer Expander Cutting Expanding Machine

8inch 12inch Semi-automatic Semiconductor Wafer Expander Cutting Expanding Machine

Common uses of wafer expansion machines: Wafer expander machine are also known as chip expansion machines or expansion machines. Widely used in the grain expansion process in the production of light-emitting diodes, small and medium power transistors, backlights, LEDs, integrated circuits, and some special semiconductor devices. For example, in the LED industry, the grain expander evenly separates tightly packed LED chips to better implant them onto the welded workpiece. It utilizes the heating plasticity of LED film and adopts dual cylinder up and down control to evenly spread a single LED chip in all directions, achieving satisfactory chip gaps and automatically forming the film without deformation. Thermostatic design ceramic plate, easy to operate and understand.

Product Details

Principle:

A wafer expander is a device used to uniformly stretch the film after the cutting process, thereby separating the cut chips and evenly pulling them apart at a certain distance. The expansion method adopts servo motor, and the expansion height and speed can be parameterized in the configured touch screen.

There are various names for wafer expansion machines:
Expanding machines, LED expanding machines, LED expanding machines, grain expanding machines, wafer expanding machines, expanding ring expanding machines, plastic ring expanding machines, chip expanding machines, chip expanding machines, 6-inch expanding machines, 8-inch expanding machines, 10 inch expanding machines, 12 inch expanding machines, semi-automatic wafer expanding machines, manual expanding machines.

2. Purpose:
After the cutting process of semiconductor integrated circuit chips from wafers, the gaps between chips are very small, which can cause collisions and edge breakage between chips, resulting in waste.
The film expander can simply and quickly expand the cut chips in the X-Y direction, uniformly increasing the spacing between chips to the desired size, separating chips, avoiding chip to chip collision damage, and obtaining intact integrated circuit chips. The workbench design with heating and adjustable temperature can improve the expansion effect and greatly increase the expansion height to meet different customer needs. The height of the expansion film can be adjusted. The speed of the protective film can be adjusted. The workbench temperature is adjustable.

3. Application areas:
The wafer expansion equipment is suitable for industries such as IC, Dior, Transistor, Glass, LED, QFN, PCB, etc. It is suitable for the expansion or stretching process after the cutting process in the production of semiconductor integrated circuit chips.

The wafer expansion machine series products are specifically designed for the expansion process after cutting wafers, LEDs, etc., equipped with imported guide rails, temperature control systems, and can evenly expand the spacing between grains. The current models of wafer expansion machines include 6-inch expansion machines, 8-inch expansion machines, 10 inch expansion machines, 12 inch expansion machines, semi-automatic wafer expansion machines, and manual expansion machines
