SOLDERING

Introduction to soldering surface mount packages

Thistextgives averybriefinsight toacomplextechnology.

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 can still be used for

certainsurfacemount ICs,butitisnot suitableforfinepitch

SMDs. In these situations reflow soldering is

recommended.

Reﬂow soldering

Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied

tothe printed-circuitboardbyscreenprinting, stencillingor

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.

Wave soldering

Conventional single wave soldering is not recommended

forsurfacemount devices(SMDs)orprinted-circuitboards

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.

•Forpackageswith leadsonfoursides,the footprintmust

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.

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.

Suitability of surface mount IC packages for wave and reﬂow soldering methods

Notes

1. Formore detailedinformationon theBGApackages referto the

“(LF)BGAApplication Note

”(AN01026); orderacopy

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 packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder

cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,

the solder might be deposited on the heatsink surface.

4. 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.

5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not

suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

6. Wave soldering is 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.
