PHILIPS SAA8122AEL

SAA8122A
Digital Still Camera Processor (ImagIC family)
Rev. 01 — 20 April 2000
Objective specification
1. Description
The DSC SAA8122A is a high performance, low power, single-chip Million
Instructions Per Second (MIPS) based signal processor, part of the ImagIC family,
which is dedicated to image processing, compression, formatting and storage. The
DSC SAA8122A is optimized for use with Philips range of CCDs (e.g: FXA1022,
2 Mpixels CCD), V-driver (TDA9991), CDS/PGA/ADC (TDA9952), allowing easy
implementation of a complete system solution and fast development of high
performance consumer digital still cameras.
The SAA8122A is designed as a single-chip device, able to perform all treatments
and connections required for a wide range of Digital Still Cameras. Its embedded
RISC CPU, for which the development environment is available, enables shorter
development and validation cycles, as well as faster feature upgrade. Since one of
the main objectives of the SAA8122A is addressing a wide range of CCD sensors, a
DSP (with advanced embedded algorithm) for camera signal processing is integrated
with a high level of programmability for pulses generation.
The JPEG core is hardware based in order to allow high-speed image data
compression.

10. Soldering
10.1 Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology. A more in-depth account
of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit
Packages (document order number 9398 652 90011).
There is no soldering method that is ideal for all surface mount IC packages. Wave
soldering is not always suitable for surface mount ICs, or for printed-circuit boards
with high population densities. In these situations reflow soldering is often used.
10.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and
binding agent) to be applied to the printed-circuit board by screen printing, stencilling
or pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example, infrared/convection heating in a
conveyor type oven. Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 to 250 °C. The top-surface
temperature of the packages should preferable be kept below 230 °C.
10.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging
and non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically
developed.
If wave soldering is used the following conditions must be observed for optimal
results:
• Use a double-wave soldering method comprising a turbulent wave with high
upward pressure followed by a smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;
– 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 is 4 seconds at 250 °C. A mildly-activated flux will eliminate the
need for removal of corrosive residues in most applications.
10.4 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 to 5 seconds between 270 and 320 °C.

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.
These packages are not suitable for wave soldering as a solder joint between the printed-circuit board
and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top
version).
If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger
than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than
0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
