Application Note
Application Note
Washing
The washing process shall be done by using easily vaporizing
materials like methyl, isopropyl, or isobutyl.
After washing the part(s), it is mandatory to take care of
sufficient drying time at high temperature.
Recommended chemicals:
Alcohols like methyl, isopropyl, isobutyl
Aliphatics like hexane or heptane
Soap solutions
Naphtha
De-ionized water
Do not use chemicals including:
(Partially) halogenated hydrocarbons
Ketones (e.g., MEK)
Acetone
Chloroform
Ethyl acetate
Phenol
Methylene chloride
Methylene dichloride
N-methylpyrrolidone
In general, it is sufficient to use simple cleaning agents like
alcohols or soap solutions. More aggressive chemicals like
halogenated hydrocarbons are needlessly demanding to the
environment and are hazardous to human health. Therefore,
these should be avoided whenever possible.
Maximum Temperature at FOT
The maximum ambient temperature must not exceed 85°C.
Guidelines for Optimum Heat Transfer to
PCB
The board should be designed for optimum heat transfer from
the device interior via the leads to the PCB. The distance of the
device body to the solder joint on the PCB shall also be
minimized and the dimensions of the conductors on the PCB
shall be maximized. Convection airflow around the devices
shall not be obstructed. Other heat generating devices shall
not be placed near the devices.
Galvanic Insulation
AFBR-39xxyyRZ is a certified optocoupler according to EN
60747-5-5:2011. Insulation values are:
For further details, refer to the data sheet.
Flammability Classification
The Flammability class is UL94-V0.
Eye Safety
The device emits light with a wavelength of 650 nm (red). This
product is designed to avoid damage to the unprotected eye.
To indicate the classification of the light source, a label as
depicted in
can be used. However these labels are not
mandatory on the product according to IEC 60825 version 1.2
paragraph 1.1.
