Data Sheet ASCB-JTC2-0A308 1615 Tricolor PLCC-4 LED Description The Broadcom® ASCB-JTC2 series are tricolor LEDs targeting indoor small pixel pitch displays. They come in a 1.6 mm × 1.5 mm × 1.0 mm PLCC-4 package. Their full black body appearance with diffused epoxy enhance display contrast and provide a suitable solution for high-resolution video display. Features   PLCC-4 package with full black body Suitable for small pitch sign Applications  Indoor full color display To facilitate easy pick and place assembly, the LEDs are packed in tape and reel form. Every reel is shipped in single intensity and color bin to ensure uniformity. CAUTION! This LED is ESD sensitive. Please observe appropriate precautions during handling and processing. Refer to application note AN-1142 for additional details.

Observe necessary precautions of handling moisturesensitive devices as stated in the following section. Do not apply any pressure or force on the LED during reflow and after reflow when the LED is still hot. Use reflow soldering to solder the LED. Use hand soldering only for rework if unavoidable, but it must be strictly controlled to following conditions: – Soldering iron tip temperature = 315°C maximum. – Soldering duration = 3 seconds maximum. – Number of cycles = 1 only. – Power of soldering iron = 50W maximum. Do not touch the LED package body with the soldering iron except for the soldering terminals, because it may cause damage to the LED. Confirm beforehand whether the functionality and performance of the LED is affected by soldering with hand soldering. Figure 15: Recommended Lead-Free Reflow Soldering Profile TEMPERATURE 10 to 30 SEC. 217°C 200°C Special handling precautions must be observed during the assembly of epoxy encapsulated LED products. Failure to comply might lead to damage and premature failure of the LED.   Handling of Moisture-Sensitive Devices This product has a Moisture Sensitive Level 5a rating per JEDEC J-STD-020. Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices, for additional details and a review of proper handling procedures. Before use:  245 – 250°C 3°C/SEC. MAX. 6°C/SEC. MAX. 150°C  3°C/SEC. MAX. 60 – 120 SEC. 100 SEC. MAX. TIME Figure 16: Recommended Board Reflow Direction Do not stack assembled PCBs together. Use an appropriate rack to hold the PCBs. For automated pick and place, Broadcom has tested a nozzle size with OD 1.5 mm to work with this LED. However, due to the possibility of variations in other parameters such as pick and place machine maker/ model, and other settings of the machine, verify that the selected nozzle will not cause damage to the LED.
