Wafer film expander is an equipment, which is used to evenly stretch the tape after the cutting process, so as to separate the chip after cutting and evenly pull apart a certain distance. Adopt servo motor to expand film, the height and speed of expanding film can be set in the touch screen.

After the cutting process of semiconductor integrated circuit chip production, the film affixed on the back of the chip after cutting is fixed with an expansion ring, and the film is evenly expanded to X-Y direction by the rise of the workbench, thus driving the chip expansion to any interval, which greatly facilitates the processing after the chip cutting process.

Semiautomatic Wafer Tape Expander is widely used in light emitting diode, small and medium transistors, backlight, LED, integrated circuits some special semiconductor devices in the production of grain expansion process. In the LED industry, for example, wafer grain expander evenly separate tight LED wafers to better fit into welders.

It makes use of the heating plasticity of LED film, adopts the upper and lower control of double cylinder to evenly spread single LED chip around and automatically from from after satisfying chip gap. The diaphragm is tight without deformation. Thermostatic design ceramic tray, easy to operate.

The process of cutting semiconductor integrated circuit chips out of the wafer, the gap between the chips is very small, resulting in the chip collision, resulting in fragmentation, waste.

The Crystal Film Expander can simply and quickly expand the cut chip in the X-Y direction, and the spacing between the chips is evenly increased to the required size, so as to separate the chip and avoid the collision damage between the chips, so as to obtain the intact integrated circuit chip. With heating and temperature adjustable table design, can make the film expanding effect better, and can greatly improve the height of film expanding, to meet the needs of different customers. The height of film expansion is adjustable. Film expanding speed is adjustable. Table temperature is adjustable.

Application:

Wafer Film Expanding Equipment is suitable for IC, Diode, Transistor, Glass, LED, QFN, PCB and other industries. It is suitable for the expansion or stretching process after cutting process in semiconductor integrated circuit chip manufacturing.

Blue Film Crystal Expander series products are specially used for wafer, LED and other cutting film expansion process, equipped with imported guide rail, temperature control system, can evenly expand the spacing between grains.
