Round-type contact mount LEDs (for automatic insertion)
● SEL6000 series LEDs packaged on tapes can withstand shocks caused by insertion machines; Thus, they can be contact-mounted automatically on circuit boards.
■ Using contact mount LEDs packaged on tapes
1. Printed circuit board
● One-side printed circuit board is recommended.
● If there are several SMD parts on the same printed circuit board, insert the LEDs after the adhesive for other SMD parts hardened.
2. Insertion conditions
● Use low insertion pusher pressure, as much as possible.
● Cut and clinch: Panasert T pattern is recommended.
For N pattern, make the clinching angle of the LED’s anode as small as possible.
3. Soldering conditions
● Preheating must be less than 90°C (temperature on printed circuit board’s bottom surface) for no more than two minutes
● Solder dipping must be made at a temperature of 250°C for no more than 3 seconds.
