Instructions for use
1. Place in a dry and closed place to prevent moisture and sticky ash
2. Do not squeeze or puncture the lens
3. When cleaning, please wipe with a clean cloth dampened with alcohol.
4. Welding, do not live welding; welding dwell time should not exceed 3 seconds
5. It is recommended to use a current driver lower than the rated voltage; heat should be handled properly
6. When using an integrated circuit, the junction temperature should not exceed 75°
7. Take precautions when using or storing static measures, such as using an electrostatic ring (ground wire), wearing an electrostatic suit
COB surface light source electrode welding operation manual
Operation process
1. Pre-solder solder on the top of the source pad (solder melt immediately)
2. Pre-weld solder on the wire
3. Pre-solder on the torch
4. The welding gun starts welding immediately after welding begins.
Instructions
1. In the first step of pad and solder operation, if the solder bar does not stop, stop soldering, indicating that the electrode is likely to be contaminated, and handle:
1) Stop heating (stop heating for a long time)
2) Use a wallpaper cutter to scrape off the contaminated layer on the electrode surface until it is exposed to silver.
2. Hanjiang recommended temperature: 280 - 300 ° C
3. Suitable platform for welding: low thermal conductivity platform (non-metal, high temperature), otherwise it will lead to rapid loss of welding heat and can not be welded. In general, in order to prohibit increasing the temperature of the torch, the ceramic substrate on the back of the mat may be a low thermal pad.
Precautions
1. Install the light source to ensure that the board is close to the pyrolytic aluminum.
2. When the illuminating board is used, sufficient heat radiation source can be obtained.
3. The product needs to be matched with the power source or the light source. Do not use it indiscriminately, otherwise the accessory will be damaged due to high voltage or large current. (A consultation can be customer service)
