免责声明

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。

Encapsulation of sensitive electronic components such as hybrid elements with wire-bonded chips.

All surfaces must be clean and free of contaminants
that will inhibit the cure of SEMICOSIL® 920 LT A/B.
Examples of inhibiting contaminants are sulfur
containing materials, plasticizers, urethanes, amine
containing materials and organometallic compounds –
especially organotin compounds.
If a substrate’s ability to inhibit cure is unknown, a
small-scale test should be run to determine
compatibility.

Caution
Only components A and B with the same lot number
may be processed together!


Component A of SEMICOSIL® 920 LT A/B contains
the platinum catalyst, component B the crosslinker.
Even traces of the platinum catalyst may cause gelling
of the component containing the crosslinker.
To eliminate any air introduced during dispensing or
trapped under components or devices a vacuum encapsulation
is recommended.

The curing time of addition-curing silicone rubber is highly
dependent on temperature, size and heat sink properties
of the component being potted.

储存

SEMICOSIL® 920 LT A/B should be stored between 5 °C and 30 °C in the tightly closed original container.

 

 The 'Best use before end' date of each batch is shown on the product label.

 

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
