Excellence in Electronics Attention Points In Handling Through-hole LEDs SLA580 Serise Visual light emitting diodes does not contain reinforcement materials such as glass fillers. Therefore if sudden thermal and mechanical shock are given, destruction or inferiority of luminous intensity may occur. Please take care of the handling. ■FIXATION METHOD 1.ATTENTION POINTS 1-1) Please do not give excessive heat over storage temperature to resin. However, In case that the product has to be heated in oven for the glue fixing, it can stand under (125℃MAX, 120secMAX) condition. 1-2) Please avoid stress to resin at high temperature. 2.TERMINATION PROCESSING 2-1) In case of termination processing, please fix the termination processing position, and process before reverse side of LED body. Please process before soldering. If stress is given during processing, It may cause non-lighting failure. To be fixed 3.ASSEMBLY ON PC BOARD 3-1) In case of soldering on PCB, if the operation is done with stress, it may cause non-lighting failure during soldering or using. ○ × ○ 3-2) Therefore please design holes of PCB suitable for termination space or termination space after forming, and avoid the stress. Especially in case of clinch to PCB, please do not leave remained stress. Enough evaluation is requested before deciding assembly conditions. Please consult with us if any problems emerged in the evaluation stage. MIN 15° MIN 45° Anode (GaAlAs chip : Cathode) REV. : A ROHM CO., LTD.

The recommendable cleaning solvent is alcoholic one such as isopropyl alcohol. RECOMMENDABLE CLEANING CONDITIONS METHOD CONDITIONS Cleaning by solvent Temperature of solvent : Max. 45℃ Immersion time : Max. 3min Cleaning by ultrasonic Ultrasonic out : Max. 15W/Liter Cleaning time : Max. 3min ■ATTENTION ON STORAGING Storage in dry box is most desirable, but if it is not possible, we recommend following conditions. Temperature : 5 ～ 30℃ Humidity : Max. 60% ■RECOMMENDABLE ROUND PATTERN Round pattern depends on the material PCB, density and circuit arrangement. Our recommendation is as follow : 2.0 1.0 ±0.1 ＊Unit : mm ＊Lead types : □0.5mm 2.5 5.0 REV. : B ROHM CO., LTD. PAGE:2/2
