4-channel I

C switch with interrupt logic and reset
–
smaller than 1.27 mm, the footprint longitudinal axis
must
be parallel to the
transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.
For packages with leads on four sides, the footprint must be placed at a 45
°
angle to
the transport direction of the printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must be fixed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250
°
C
or 265
°
C, depending on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most
applications.
15.4 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage
(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be
limited to 10 seconds at up to 300
°
C.
When using a dedicated tool, all other leads can be soldered in one operation within
2 seconds to 5 seconds between 270
°
C and 320
°
C.
15.5 Package related soldering information
[1]
For more detailed information on the BGA packages refer to the (LF)BGA Application Note(AN01026);
order a copy from your Philips Semiconductors sales office.
[2]
All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal or
external package cracks may occur due to vaporization of the moisture in them (the so called popcorn
effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit
Packages; Section: Packing Methods
[3]
These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with
peak temperature exceeding 217
°
C
±
10
°
C measured in the atmosphere of the reflow oven. The package
body peak temperature must be kept as low as possible.
