In the LED lamp packaging process, the early 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, and In these processes, the oven cannot be mixed to prevent problems such as glue poisoning, silver glue vulcanization, and pollution. Shenzhen Yihexing Electromechanical Technology Co., Ltd. has focused on the production and sales of photoelectric ovens for 18 years, and summarizes the purchase guide for LED ovens for you.
1. The LED packaging oven must be a hot air circulation oven, because the temperature uniformity of the hot air circulation oven is better, and the oven with poor uniformity will cause blistering after the glue is cured, the color difference of the phosphor, and the support substrate warping after baking For inequality, the commonly used hot-air circulating oven has a temperature between 80°C and 175°C. Therefore, when choosing a hot-air circulating oven, pay attention to the temperature range. The oven adopts an oven with a left and right horizontal wind structure, which is less affected by the number of products placed.
2. Product specifications for LED packaging baking boxes. Because the LED packaging process requires materials, semi-finished products, and intermediate products to be exposed to the environment as short as possible, the LED packaging oven should use a 3-layer or 4-layer oven as much as possible, and each layer of temperature control system is independently controlled.
3. The LED packaging baking box should have a heating timing function, because the baking time is required in the production process. 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 temperature controller needs to be able to achieve a curve temperature rise. This benefit can be achieved by adjusting the heating rate to solve the glue curing requirements of different products.
4. Pay attention to the problem of the air intake and exhaust when purchasing the LED package oven. Silver glue, epoxy glue, brackets and other materials are easily oxidized products. Silver glue, glue baking will produce harmful gases, and the baking process should not be The outside air exchanges to prevent glue poisoning, vulcanization and other problems. Therefore, the air inlet and exhaust outlet of the oven should be adjustable and need to be closed during the baking process.
Yihexing LED photoelectric oven is suitable for curing and baking in the photoelectric industry. It adopts LED dual-digital display intelligent temperature control, PID calculation, automatic temperature control, simple operation, accurate temperature control, and can be improved and customized according to customer or product process requirements One or more independent studios (OEM& ODM), programmable multi-segment temperature control time control, more energy-saving and more user-friendly in use.
