Hello, everyone, in the process of using [UV tunnel furnace], occasionally customers will ask the problem of UV tunnel furnace correction, UV glue curing surface dry is not very good, the glue is too dry, the curing speed is too fast or too slow, and so on. Today, Auvcure’s Xiaobian will share this knowledge with you.
In fact, setting up and optimizing UV delivery equipment is a simple process.
It can be done in three simple steps, but before the correction, we need to prepare the following things:
1, UV glue or other UV coating technical data sheet (TDS) : ask UV glue or UV coating manufacturers
2, UV radiometer (calibration and certification)
With the above two things, we can test and optimize the UV curing furnace, but we also need to know some knowledge about the UV tunnel furnace. The key to optimizing the UV tunnel furnace process is that we also understand how much energy and light intensity values are required for the UV coating used, which is a property of the spectral output of the UV tunnel furnace, allowing us to ensure that the coating is properly cured.
Two or three simple steps to calibrate the UV tunnel furnace:
Step 1: First know the curing energy section of the TDS of the UV coating you are using, and find the recommended energy and light intensity value at each wavelength. If for some reason the information does not exist, please call your material supplier and ask them to provide the above information.
Step 2: Use the UV radiometer to measure the spectral output of the UV tunnel furnace. This measuring tool and its use are an integral part of calibrating UV tunnel furnaces. Run the UV radiometer and through the UV tunnel furnace, check the recorded energy and light intensity values on the display, and compare the requirements on the TDS. Now that you find the product’s TDS and UV radiometer output value for the UV output target, it’s time to move to step 3 calibration.
Step 3: The curing conditions of the UV tunnel furnace should be adjusted according to the results of the light intensity meter, if the energy is low, slow down the conveying speed; If the energy is high, increase the transmission speed; If the light intensity is low, reduce the height between the bulb and the circuit board; If the light intensity is high, increase the height between the UV light source and the substrate.
The above is how to set up and calibrate the UV curing furnace related knowledge.
