■ Cleaning

Residual solder of flux left on the LED housing could reduce intensity

and could affect the optical characteristics. Excess flux can be

removed by the following chemical method:

1. Cleaning solvents (dipping time: 3 minutes maximum at

normal temperature)

• Ethyl alcohol

• Isopropyl alcohol

• Pure water (after cleaning, the water must be removed

by drying)

• Drying condition: 90°C max., 30 sec. max. and 4 times max.

2. The effect of ultrasonic cleaning on the LED resin body depends

on such factors as the oscillator output, size of PCB and LED

mounting method. Ultrasonic cleaning is strongly recommended

after confirming that there are no problems.

1. Ultrasonic wave frequency: 28 kHz or 40 kHz

2. Output: 20 W/I

3. The solvent for freon equivalent (recommended after confirming

that there are no problems).

• AK-225AES

• Clean through

• Pine alpha ST-100S

Chemicals
