AP702
USB Host and PLL Interface with DSP and MCU Controller
1. OVERVIEW
AP702 is an USB Host and PLL Interface with DSP and MCU Controller. It has a built-in 24-bit DSP for MP3 and WMA decoding,
an 8-bit MCU for CD servo control, ISO9660 file system handling and user interface function control. An USB host controller is
included in AP702 to support the data control and playback of MP3 files on portable MP3 players. AP702 also offers SD card
support, giving the end customers a luxury of a SD card plug-and-play element. This chip also has an on-chip PLL controller for
external tuner IC to form a complete digital tuning system. This system-on-chip solution is ideal for CD-base audio products

11. SOLDERING INDICATION
This section gives a very brief insight to a complex technology. There is no soldering method that is ideal for all surface mount IC
packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these
situations reflow soldering is recommended.
1. 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, stenciling or pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example, convection or convection/infrared 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 220 °C for thick/large packages, and below 235 °C for small/thin packages.
2. 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:
z
Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth
laminar wave.
z
For packages with leads on two sides and a pitch:
– 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.
z
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.
3. 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.

Suitable
Notes
1. 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).
2. 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).
3. If wave soldering is considered, 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.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch equal to or larger than 0.8 mm; it is
definitely not suitable for packages with a pitch equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch equal to or smaller than 0.5 mm.
