SOLDERING
The indicated temperatures are those at the solder
interfaces.
MGM159
300
handbook, halfpage
Advised solder types are types with a liquidus less than or
T
(°C)
equal to 210 °C.
Solder dots or solder prints must be large enough to wet
the contact areas.
200
100
Soldering can be carried out using a conveyor oven, a hot
air oven, an infrared oven or a combination of these ovens.
A double reflow process is permitted.
Hand soldering must be avoided because the soldering
iron tip can exceed the maximum permitted temperature of
250 °C and damage the module.
0
0
The maximum allowed temperature is 250 °C for
5 seconds.

t (min)
The maximum ramp-up is 10 °C per second.
The maximum cool-down is 5 °C per second.
Fig.17 Recommended reflow temperature profile.
Cleaning
The following fluids may be used for cleaning:
• Alcohol
• Bio-Act (Terpene Hydrocarbon)
• Acetone.
Ultrasonic cleaning should not be used since this can
cause serious damage to the product.

Product specification
This data sheet contains target or goal specifications for product development.
This data sheet contains preliminary data; supplementary data may be published later.
This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices, or systems where malfunction of these
products can reasonably be expected to result in personal injury. Philips customers using or selling these products for
