I. Introduction:

Wafer Coating MachineIt is known by various names: wafer expansion machine, wafer enlargement machine, wafer expander, LED wafer expansion machine, LED film expansion machine, die expansion machine, wafer expansion machine, ring-type wafer expansion machine, plastic ring film expansion machine, wafer expansion machine, wafer enlargement machine, 6-inch wafer expansion machine, 8-inch wafer expansion machine, 10-inch wafer expansion machine, 12-inch wafer expansion machine,Semi-automatic wafer film coating machine, manual crystal-growing machine.


A wafer film stretching machine is a piece of equipment used after the cutting process to stretch the film uniformly, thereby separating the cut chips and spacing them evenly apart by a specific distance. The machine utilises a servo motor for film stretching, and the stretching height and speed can be configured via the touchscreen.
Following the dicing process, in which semiconductor integrated circuit chips are cut from a wafer, the gaps between the chips are very small, which can lead to the chips colliding with one another and causing chipped edges, resulting in waste.

The film expansion machine can quickly and easily expand cut chips in the X-Y directions, uniformly increasing the spacing between chips to the required dimensions, thereby separating them and preventing damage caused by collision, thus producing intact integrated circuit chips. The worktable is equipped with a heating system and features adjustable temperature settings, which enhance the spreading effect and significantly increase the spreading height to meet the diverse needs of customers. The spreading height is adjustable. The spreading speed is adjustable. The worktable temperature is adjustable.

II. Areas of application:

Wafer expansion equipment is suitable for industries such as ICs, diodes, transistors, glass, LEDs, QFNs and PCBs, and is used for the expansion or stretching process following the dicing stage in the manufacture of semiconductor integrated circuit chips. The wafer expansion machine series is specifically designed for the post-cutting expansion process of wafers, LEDs and similar components. Equipped with imported guide rails and a temperature control system, it ensures uniform expansion of the spacing between grains. Current models of wafer expansion machines include: 6-inch expansion machines, 8-inch expansion machines, 10-inch film expansion machines, 12-inch film expansion machines, semi-automatic wafer film expansion machines and manual film expansion machines. For custom sizes, please contact Mr Liu on 18928278160 (same number for WeChat).

Purpose:

It is widely used in the wafer expansion process for the manufacture of light-emitting diodes, low- to medium-power transistors, backlight units, LEDs, integrated circuits and certain specialised semiconductor devices.

Take the LED industry, for example: chip spreading machines evenly separate closely packed LED chips, enabling them to be mounted more effectively onto the workpieces to be soldered. It utilises the heat-induced plasticity of the LED film and employs dual-cylinder top-and-bottom control to evenly spread a single sheet of LED chips in all directions; once a satisfactory chip spacing is achieved, the machine automatically forms the film, ensuring it remains taut and free from deformation. The worktable features a constant-temperature design and is simple and intuitive to operate.

Points to note when selecting a wafer film expansion machine: Please provide the dimensions of the inner and outer rings of your expansion ring, as well as the type of film you are using. Contact Dongguan Judeweiye Electronic Technology Co., Ltd. for a bespoke solution: Mr Liu on 18928278160.

III.Key features of this machine:

➢ The height and speed of the film expansion can be set digitally via the touch screen;
➢ The work tray is equipped with a constant-temperature heating function, which helps to improve the film’s ductility;
➢ By adjusting the height at which the work tray rises, you can adjust the spacing between managers;
➢ Optional top-mounted hot-cut automatic film-cutting function.
➢ 5-inch touchscreen displaying parameters, operating steps and fault alerts
➢ The film stretching process is carried out using motorised and pneumatic lifting mechanisms, ensuring consistency in the stretching process
➢ The control system utilises an imported PLC, allowing functions such as the preheating delay for the platen rise and the film expansion delay to be set, thereby further improving the quality of film expansion.
