Storage and transportation

1. The digital tube should be well protected against moisture for electronic products;

2. The digital tube is an electrostatic sensitive device. When a printed circuit board with a static sensitive device or a whole machine is stored, antistatic measures should also be taken;

3. When transporting or delivering, it is necessary to minimize mechanical vibration and impact; it should be handled gently during handling, and should not be stacked too high during stacking, nor

Put too heavy items on top to avoid crushing the LEDs.

Digital tube welding conditions

1, manual welding temperature: <250 degrees; welding time: 3s

2, immersion tin, wave soldering preheating temperature: 100 degrees (not more than 120 degrees, warming up)

3, welding temperature: 235-245 degrees (to find the best temperature)

4, welding time: <3s

5, beyond the above conditions, the digital tube failure rose sharply

Conditions of use: (Recommended for constant current use, uneven brightness will appear at constant pressure).

1. When using, the current and voltage must be correct; the current limiting resistor is added to the segment and the decimal point;

2. The product should not be stored and used under corrosive gas, and it should not be exposed to the air for too long, otherwise it will lead to oxidation;

3. All equipment and instruments that touch digital must be grounded;

4. Products with protective film on the surface can be torn off before use;

5. After the protective film is torn off, do not touch the surface of the digital tube with your hand;

6, the use of voltage: segment = VF; decimal point = VF;

7, the use of current:; dynamic average current 3-5mA; 1 / 8 duty cycle, peak current 40mA; static: 5-10mA per segment.

8. Take anti-static measures when using blue, emerald and white digital tubes.
