The fluctuating silver price, which is currently again on a high level, makes it difficult to keep cost under control. Low silver alloys could for devices not exposed to high thermal stress, a valuable alternative for SAC305 alloys. Typical we look for electronics placed inside the passenger compartment.

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.

The idea behind No-clean soldering is to avoid an additional cleaning step in your overall process. For certain critical applications however, there is no room for failure and removal of any contaminations left on the PCB is required. This is especially true for the automotive, Aerospace and Medical industry, where the expected life-time of the electronics are many years and where some electronic devices are critical for health & safety.

It is common knowledge that assemblies exposed to higher temperatures are more prone to electrochemical migration and leakage current. This makes cleaning of PCB’s exposed to this kind of environment a valuable choice. Also when applying a protective coating it is also advised to clean prior to the coating process in order to maximize the coating adhesion.

Inventec has developed a dedicated range of defluxing agents suited to you desired process. Designed to cater high volume assemblies with a fast and effective cleaning and with high regards to their environmental impact.

In order to extend the life time of your electronic assembly and protect it against harsh environments they operate in, coating is a valuable option. Also they can provide additional mechanical strength to the assembly by absorbing vibrations.

Inventec offers several conformal coatings & ultra-thin coatings. Ultra-thin coatings offers a more simple and cost advantage process, while traditional conformal coatings provide a more rigid protection. They both can be applied by selective spray or by dipping.

Although heat curing of conformal coatings is still very popular, we believe in the future of UV curing. Especially by using UV LED instead of the traditional mercury UV lamps, which is a more stable, cost-efficient and environmental processes.

When applying a protective coating it is also advised to clean prior to the coating process in order to maximize the coating adhesion. With Inventec you have a partner which can offer you soldering, cleaning and coating solutions. Designed to be compatible with each other to minimize the risk of compatibility issues.
