1. When soldering with reflow methods, Sharp recommends following the soldering profile in Fig. 13.

2. Electrodes on this part are silver-plated. If the part is exposed to a corrosive environment, the plating may be

damaged, thereby affecting solderability.

3. Do not subject the package to excessive mechanical force during soldering as it may cause deformation or

defects in plated connections. Internal connections may be severed due to mechanical force placed on the pack-

age due to the PCB flexing during the soldering process.

4. Both PCB design and solder reflow machine specifications will affect the amount of heat conducted into this part

during the production process. Sharp recommends verifying the process before production begins.

5. When using backside dip methods, Sharp recommends giving careful consideration to the process, as board

warping from heat may occur and the heat itself may be conducted into the package. Reflow after dip is recom-

mended, but they can be performed in the opposite order; keep the interval between the two processes as short

as possible.

6. When using a second reflow, the second process should be carried out as soon as possible after the first, unless

there is a water-wash or solvent-wash process. Then the parts must be baked as specified in Storage and Han-

dling before performing the second reflow.

7. The Reflow Profile shown in Fig. 13 should be considered as a set of maximum parameters. Since this part uses

the leads for heatsinking, the peak temperature should be kept as cool as possible and the cooldown period

lengthened as much as possible. Thermal conduction into the LED will be affected by the performance of the

reflow process, so verification of the reflow process is recommended. These parts may be used in a nitrogen

reflow process.
