A light-emitting diode, or LED for short, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply so that the entire chip is encapsulated by epoxy resin. In the LED lamp packaging process, the pre-LED bracket baking, the silver glue curing after the dispensing process, the short baking (pre-curing) and the long baking (post-curing) after the potting process all need to use an oven.
Yee Hing LED photoelectric industry curing oven is widely used in the production of LED light-emitting diodes, digital tubes, dot matrix backlight epoxy resin, silver glue and baking electronic parts. According to the LED packaging process requirements, the photoelectric oven has the following characteristics:
1. With hot air circulation function. The hot air circulation oven has better temperature uniformity, which can avoid blistering after the glue is cured, the color difference of the phosphor, and the unequal warpage of the support substrate after baking.
2. Diversity of specifications. Because the LED packaging process requires materials, semi-finished products, and intermediate products to be exposed to the environment for as short a time as possible. Therefore, it can be improved and customized according to the process requirements of customers or products. One or more independent studios (OEM& ; ODM), programmable single-stage or multi-stage temperature control time control, more energy-saving and more user-friendly in use.
3. With heating timer function. The baking time is required in the production of LED technology. If the baking time is too short, the glue cannot be completely cured. If the baking time is too long, the glue will harden, crack, and degummed. In addition, the thermostat can realize the curve heating, which has the advantage of adjusting the heating speed to solve the glue curing requirements of different products.
4. Adjustable air inlet and exhaust holes. Silver glue, epoxy glue, brackets and other materials are easily oxidized products. Silver glue and glue baking will produce harmful gases. Try not to exchange with the outside air during the baking process to prevent glue poisoning and vulcanization.
5. All electrical accessories adopt first-line brands. PID calculus temperature control system and over-temperature protection device, intelligent constant temperature, small temperature difference, suitable for long and short baking of different manufacturers and products.
