RECOMMENDED WAVE SOLDERING PROFILE

Notes:

1. Recommend pre-heat temperature of 105°C or less (as measured with a thermocouple

attached to the LED pins) prior to immersion in the solder wave with a maximum solder bath

temperature of 260°C

2. Peak wave soldering temperature between 245°C ~ 255°C for 3 sec (5 sec max).

3. Do not apply stress to the epoxy resin while the temperature is above 85°C.

4. Fixtures should not incur stress on the component when mounting and during soldering process.

5. SAC 305 solder alloy is recommended.

6. No more than one wave soldering pass.

PRECAUTIONS

Storage Conditions

1. Avoid continued exposure to the condensing moisture environment and keep the product away from rapid transitions in ambient

temperature.

2. LEDs should be stored with temperature ≤ 30°C and relative humidity < 60%.

3. Product in the original sealed package is recommended to be assembled within 72 hours of opening.

Product in opened package for more than a week should be baked for 30 (+10/-0) hours at 85 ~ 100°C.

Correct mounting method " x " Incorrect mounting method

LED Mounting Method

1. The lead pitch of the LED must match the

pitch of the mounting holes on the PCB

during component placement.

Lead-forming may be required to insure

the lead pitch matches the hole pitch.

Refer to the figure below for proper lead

forming procedures.

Note 1-3: Do not route PCB trace in the contact area between the

leadframe and the PCB to prevent short-circuits.

Lead Forming Procedures

1. During soldering, component covers and holders should leave

clearance to avoid placing damaging stress on the LED during

soldering.

2. The tip of the soldering iron should never touch the lens epoxy.

3. Through-hole LEDs are incompatible with reflow soldering.

4. If the LED will undergo multiple soldering passes or face other

processes where the part may be subjected to intense heat,

please check with Kingbright for compatibility.
