CLD-CT1489 REV 3 Screen Master® 4-mm Oval LEDs: C4SMB-AGY PRODUCT DESCRIPTION These oval LEDs are specifically designed for full-color video screens, digital billboards and passenger-information signs. The oval- shaped radiation pattern and high luminous intensity ensure that these devices are excellent for bright sunlight or low power consumption outdoor applications. These lamps are made with an advanced optical-grade epoxy that offers superior high-temperature and high-moisture- resistance performance in outdoor signal and sign applications.The encapsulation resin contains anti-UV material in order to reduce the effects of long-term exposure to direct sunlight.

CLD-CT1489 REV 3 SOLDERING GUIDELINES The LED soldering specification is shown below(suitable for both leaded solder & lead-free solder): Manual Soldering Solder Dipping Soldering iron 35 W max Preheat 110 ºC max Temperature 300 ºC max Preheat time 60 seconds max Solder-bath temperature 260 ºC Max Soldering time 3 seconds max Dipping time 5 seconds max Position Not less than 3 mm from the base of the package. Position Not less than 3 mm from the base of the package.

  • Manual soldering onto the PCB is not recommended because soldering time is uncontrollable.
  • The recommended wave soldering is as below: 10 20 30 40 50 60 70 80 90 100 110 120 150 100 300 250 200

50 Temperature ºC

Times (sec) laminar wave Fluxing Preheat

  • Do not apply any stress to the LED package, particularly when heated.
  • Only bottom preheat is suggested & should not preheat on top in order to reduce thermal stress experienced by the LEDs.
  • The LEDs must not be re used once they have been extracted from PCB.
  • After soldering the LEDs, the package should be protected from mechanical shock or vibration until the LEDs have reached 40 ºC or below.
  • Precautions must be taken as mechanical stress on the LEDs may be caused by PCB warpage or from the clinching and cutting of the LED leads.
  • When it is necessary to clam the LEDs during soldering, it is important to ensure no mechanical stress is exerted on the LEDs.
  • Cut the LED lead at normal room temperature. Lead cutting at high temperature may cause failure of the LEDs.
  • Please refer to the HB LED Lamp Soldering & Handling document for information about how to use this LED product safely.
