What’re the next steps of packaging the LED

1 , filling plastic packaging

Lamp-LED uses potting form to package. What the Potting process is injrcting the LED liquid epoxy into mold cavity , and then insert the LED holder welded, then place in an oven to cure the epoxy , the LED from the mold cavity formed is in the extrusion .

the development of packaging the LED

2, molded package

Put the LED bracket welded into the mold, use the hydraulic clamping to clamp the mold and extract the vacuum, put the solid epoxy into the dispensing channel inlet to heat and use the hydraulic plunger to press into the mold runner , the epoxy run along the plastic molding tract into the groove and each LED curing .

3 , curing and post-curing

Curing is encapsulated epoxy curing,the epoxy curing conditions is generally 135 ℃, 1 hr. Molded package is generally 150 ℃, 4 minutes.

4 , post-curing

After curing is allowing the epoxy to be cured sufficiently, at the same time for thermal aging of the LED . After curing is very important to improve the adhesive strength. of the stand (PCB)and  the epoxy. General conditions is 120 ℃, 4 hours.

5, cut tendons and dicing

As the LED are linked ( not individual ), Lamp LED package LED stent adopts the cut tendons to cut off the connection tendons. SMD-LED is on a PCB board , which needs the separation Dicing to complete .

6 , the test

Test LED photoelectric parameters , inspection dimensions, while sorting the LED products according to customer requirements.

What are the first five steps of packaging LED

LED packaging technology mainly turn to high luminous efficiency, high reliability, high heat capacity and thin, the main highlight is the ceramic substrate package, flip technology , the phosphor coating technology , wire bonding technology . LED packaging steps can be divided into twelve steps .

1 , dispensing

Pointing the LED bracket silver plastic or rubber insulation on the corresponding position . ( For GaAs, SiC conductive substrate , a back electrode red, yellow , green chips, using silver paste; for an insulating substrate of sapphire blue , green LED chips, using an insulating adhesive to fix the chip. )

2, automatic pallet

Automatic loading rack is actually a combination of glue stick ( dispensing ) and mounting the chip, the first point in the LED bracket silver plastic ( plastic insulation ) , and then use a vacuum suction nozzle from the LED chip mobile location, and then placed in the corresponding bracket position.

Automatic loading rack should be familiar with the main programming device operation in the process , while precisely adjusting the dipping equipment and installation. The selection of the nozzle try to use bakelite nozzle to prevent damage to the surface of the LED chip , especially blue, green chips must be bakelite . Because steel mouth will scratch the surface of the chip current spreading layer .

LED package device

3 , the sintering

The purpose is to cure the silver plastic, sintering required to monitor the temperature and prevent adverse batch .

Silver plastic sintering temperature is controlled at 150 ℃, sintering time is 2 hours ,which can be adjusted to 170 ℃, 1 hr according to the actual situation.

Plastic insulation generally 150 ℃, 1 hr.

Silver plastic sintering oven must be opened to replace the sintered products in separated 2 hours ( or 1 hour )according to process requirements, intermediate can not be opened . No further purpose is for other sintering oven to prevent contamination.

4 , pressure welding

The purpose of bonding is to lead the electrode to the LED chip to finish lead connections inside and outside the product .

There are the gold ball bonding welding and aluminum wire bonding for the process of LED. Bonding is the key process in the LED packaging technology , the main process is the need to monitor the bonding gold ( aluminum ) wire arch shape , spot shape , tension.

There are various issues involved in-depth study for the bonding process , such as gold ( aluminum ) wire material , ultrasonic power , pressure welding pressure , chopper ( steel mouth ) selection, chopper ( steel mouth ) trajectory and so on.

5 , dispensing package

LED package mainly are little glue , potting , molding. The difficulty is basically bubble process control , multi- material shortage , black spots. Designed is mainly for selecting the material, combined with a good selection of epoxy and bracket. ( General LED can not through leak test ) TOP-LED and Side-LED is suitable for dispensing package as shown. Manual dispensing package demand highly for operating level ( especially white LED), the main difficulty is controlling the dispensing volume, because the epoxy will be thick during use .what the problems caused by dispensing the white LED phosphor is the light color precipitate.

In addition to packaging the LED , LED application especially LED lighting is also very extensive,such as the outdoor LED flood light  as the representatives of the decorative lighting and the outdoor lighting enjoying a great popularity in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the brighter  light need to illuminate,moreover,there a large number of factory engaging in developing and producing the outdoor LED flood light,Lead Lighting is just one of them,which adopts highly integrated and high brightness COB as the light source of the outdoor LED flood light so that fully guarantee the  octahedron breadth and brightness irradiation range of the outdoor LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of outdoor LED flood light and reduce the wasted heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is known as energy-saving and environmental protection. Login http://www.lead-lighting.com/products/sid53-1.htm  to know more awesome and practical outdoor LED flood light.
