1. When soldering with reflow methods, Sharp recommends following the soldering profile in Fig. 15.

2. 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.

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

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

damaged, thereby affecting solderability.

5. The Reflow Profile shown in Fig. 15 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.

?SPAN class="pst GM5BW96385A_2662290_2">Recommended Solder Pad Design

1. Solderability depends on reflow conditions, solder paste, and circuit board materials. Check the entire process

before production commences.

2. Fig. 16 shows the recommended solder pad design for this part.

3. When using backside dip methods, Sharp recommends checking the process carefully: board warping from heat

can cause mechanical failure in these parts, in addition to the high heat conducted into the part through the

leads. Performing reflow after dip is recommended, with the interval between the two as short as possible.
