Lighting
As external lighting in automotive does not only add to the driving comfort but also is a key safety feature, it requires reliable solutions in order to prevent premature failure.
LED’s are commonly used today due to their great performance, design flexibility and reduced energy consumption. However, LED’s require special attention in terms of heat management and may need coatings to protect it against exposure to harsh environments.
Also as a vehicle undergoes constant vibrations, choosing a solder alloy better resistant to vibrations may enhance the reliability of your product.

Heat dissipation in LED’s, especially in high power LED’s, is an important factor to maintain an optimal light output. Higher junction temperatures reduces light output, in particularly the amber and red wave lengths. Secondly, poor thermal management will accelerate the gradually decrease of light output over time.
It’s commonly known that voids in the solder, decreases the ability to dissipate the heat at the junction of the LED assembly. Using solder materials who are designed to keep voiding to a minimum is therefore recommended. In automotive this is specifically significant for front LED lighting.

The fluctuating silver price, which is currently again on a high level, makes it difficult to keep cost under control. Low & No silver alloys could for devices not exposed to high thermal stress, a valuable alternative for SAC305 alloys. Automotive rear lights which compared with front lights work at a lower power level, can be a valuable application to implement these alloys.
The wetting behaviors of low-silver alloy SnAg1.0Cu0.5 are comparable to a considerable degree with eutectic standard SnAg3.0Cu0.5 and can be in many cases used as a “drop in” solution. Not only cost could be a decision factor but also the drop and vibration resistance of a low silver alloy compared to SAC305 could favor these alloys. Low silver alloys are the number one choice these days for handheld devices, particularly for this reason.

LED’s used for outside applications and exposed to weather conditions and humidity or placed in a harsh environments, can benefit greatly from coating them with an Ultra-thin coating. The higher the power of the LED, the more risk to dendrite growth and corrosion when exposed to humidity. Ultra-thin coatings are only around 1 micro thick but provide sufficient protection against unwanted influences from the environment. These coatings will create no loss of light emissions or color changes.
Part of the LED module or the whole assembly can be simply dipped in the coating. This provides you with a simple and fast process. The coating dries in ambient air in a few seconds.
In automotive, target applications are the external lights, especially the high power front lights.
