GENERAL INFORMATION
HOW TO USE INVISIBLE PRODUCTS
 SOLDERING
1. Soldering Bath--260±5℃ Within 5 seconds. (Dip depth should under 1/16 inch below seating plane)
2. Soldering Iron Under 40W within 3 seconds. (Tip temperature: 380±5℃)
3. The neutrality flux be used before soldering.
 CLEANING
1. Do not use unspecifired chemical liquid to clean invisible product. They could harm the invisible product. If cleaning is
necessary, wipe the pin out with alcohol, Freon TE or Chlorosen at normal temperature for less Than 1 minute, or wipe the
surface with alcohol. When other chemical solutions mot specified is used. It may cause crack or haze on the surface of the
lnvisible product.
 PREVENTING OVER CURRENT
1. Be not overcurrent.
2. In order to cooperate INVISIBLE PRODUCTS under stable conditions. Put protective resistors in series. Resistor values
can be determined by supplying voltage or current is in the invisible product. Recommended current is in the range of
forward current 50mA.
3. Circuit must be designed so that over voltage (over current) is not applied to the invisible product during on/off switching.
Transient or pulse current will damage the junction of invisible product die.
 BRIGHTNESS
1. For obtaining even brightness. Each segment should be at the same current, so the best circuit design is to supply constant
current for each segment.
0000000000000000000000000000000000000000000000000000000
2. To increase brightness. Increase current. But do not over maximum rating.
3. To check the appearance defect of invisible product, the viewing distance should be 15cm minimum
4. For obtaining more uniform brightness on SIDE LOOK and INTERRUPTER. The supplying forward current should be
over 20mA, but do not be over rating.
