Location plays an important role in the entire manufacturing process.

It is recommended to start the LED light business in an industrial area, because the manufacturing process requires a certain amount of space to produce LED lights.

When choosing a location, please make sure it is available and must be delivered to the raw material supply by transportation.

The area also includes warehouses, packaging units and office space; 500 square meters of LED light production can be started

It is recommended to divide the area into three compartments, one for the processing unit (280 square meters), and the second for the storage area ( 93 square meters), where you can store the materials and components of the raw material of LED bulb. The last compartment is used to install and test (185 square feet)

LED bulbs. In addition, please make sure that the location of your LED lamp manufacturing plant complies with regulations that mention the legal requirements of the energy industry.

LED bulb manufacturing process

Step 1

1.wafer production 

First, make wafers, GaAs, GaP and other composite materials, which are determined by the color of the light-emitting LED.

Forms crystalline semiconductors in high temperature and high pressure chambers.

Gallium, arsenic and/or phosphorous are cleaned and mixed in a high temperature and high pressure chamber.

2. Liquid encapsulation:

The components are liquefied and compressed, and then forced to dissolve. To prevent them from entering the chamber, they are coated with a layer of boron oxide to isolate them. This process is called a liquid capsule.
elements are thoroughly mixed and form a homogeneous solution. Dip the rod in the solution and slowly remove it from the chamber. As the solution moves away, it cools and forms a long crystal ingot of GaAs, GaP, or GaAsP.

3. Polishing wafers:

cutting the beads into thin wafers of semiconductors (approximately 10 mils).

Polish the wafer until its surface is smooth, so that the wafer can quickly pick up other semiconductor layers on the surface.

4. Printing plate cleaning:

The produced printing plates are thoroughly chemically and ultrasonically cleaned with various solvents; this process can remove organic materials that may accumulate on the polished surface of the wafer.

This cleaning process will produce better LEDs.

Step 2 Add epitaxial layer

5. Make a semiconductor crystal layer on a clean, polished wafer surface. This process is called liquid phase epitaxy (LPE).

In this process, a semiconductor layer with the same crystal orientation is deposited on the wafer. The layered plate is located on the graphite plate and pushes the channel into the molten liquid.

Adds various dopants to the melt to produce layers of materials with different electron densities. The deposition has become the crystal structure of the wafer.

Liquid phase epitaxy (LPE) can form a uniform material layer several microns thick.

6. After adding multiple layers, additional dopants must be added to change the characteristics of the diode in terms of efficiency and color.

After additional alloying, the plate is placed in the high pressure furnace again under a gas atmosphere containing alloy additives such as nitrogen or zinc ammonium; nitrogen is added to the top layer of the diode to make it light yellow or green.

Add metal contacts

7. Insert metal contacts: Insert the metal contacts into the board.

The contact pattern depends on the design stage and the combination of diodes (alone or in combination).

The contact pattern is replicated in photoresist. It is a photosensitive compound that is scattered on the surface of the printing plate. The photoresist will harden under the pants at a low temperature of about 100°C.

The pattern is copied to the photoresist by layering the pattern on the board and exposing the photoresist to ultraviolet light.

The exposed area of ​​the photoresist protective layer is washed with a developer, and the unexposed area is covered with a semiconductor layer.

8. The contact metal evaporates in a further high-temperature sealed chamber and fills the open area.

The contact metal adheres to the exposed area of ​​the wafer. The photoresist can be rinsed off with acetone. This leaves only metal contacts. On the semiconductor wafer.

According to the final LED installation plan, add a layer of metal on the back of the panel.

The deposited metal undergoes an annealing process in which the plate is heated in an oven in an inert atmosphere of hydrogen or nitrogen for several hours; in this process, the bond between the metal and the semiconductor becomes stronger.

9. A similar pattern is repeated up to 6000 times on a 2-inch board made in this way; this gives an idea of ​​the oscillation of the finished diode.

The diode is cut or sawed, and each segment cut from the board is called a mold. This is a complicated process with many defects.

Splitting or cutting results in the total number of available LEDs being less than 6,000, which is one of the main difficulties that limit the cost of manufacturing semiconductor devices.

Step 3 Assembly and packaging

10. A single stamp is assembled approximately in the packaging; it is mounted on two 2-inch cables.
The back of the
board is coated with lead metal to make electrical contact with the wires on which it rests. A thin gold wire is soldered to the other lead, and the material is glued to the contacts of the chip surface pattern.

Using wire bonding, the edge of the lead is pressed against the contact metal with a thin needle. Gold is very brittle and can be bent and adhered to similar metal surfaces.

11. Finally, seal the entire assembly with plastic, hook the wires and the mold into a shape corresponding to t.
