Recently, Shin-Etsu launched a new line of products codenamed “Tiger LF”. These “Tiger” leadframes are Shin-Etsu’s answer to the LED and solar market to replace the industry’s conventional PPA plastic housing with a premolded leadframe using Shin-Etsu’s patented Silicone Molding Compound – its SWC-Series products. CAPLINQ is proud to support Shin-Etsu in this highly specilized [...]

Many customer have requested whether CAPLINQ can offer thinner polyimide tapes. CAPLINQ is pleased to announce LINQTAPE PIT0.5S a 0.5mil (13 micron) Polyimide Film with a 1mil (25 micron) silicone adhesive. LINQTAPE PIT1S has a backing thickness of 1mil (25 micron) and the adhesive layer adds another 1.5 mil (36micron) for an overall thickness of [...]

Shin-Etsu KJR silicones are used extensively in the manufacture of ICs, transistors, diodes and other semiconductor devices. KJR-4013E is a flexible, moisture-cure silicone most often used as junction-coating resins in the manufacture of diodes. KJR-651E, KJR-655E and KJR-657E are rigid thermoset polyimide-silicones used as junction coating resins in the manufacture of higher power diodes and [...]

Generally speaking, the acrylic adhesive will have higher adhesion at mid-range temperatures (0°C to 100°C), but silicone adhesives have higher adhesion at lower temperatures (under 0°C) and higher temperatures (above 100°C). This adhesion is independent of the tape thickness (1mil, 2mil or 5mil) as the adhesive layer thickness remains constant. This is substrate dependent and [...]

As described in the article “How Polyimide Tapes are Made“, tapes are composed of two distinct layers, each of which is critical to the properties of the final product. The first layer is the backing material, and whether this is polyimide film (the generic verison of DuPont’s Kapton), polyvinyl chloride (PVC), Polyethylene terephthalate (PET), or [...]

Shin-Etsu offer a range of silicone materials suitable for optical fiber coating. The fiber coating application can be broken down into two categories, the “primary coating” through which the light or data must pass and the “buffer coating” whose optical properties must be different than the primary coating. Shin-Etsu offer a range of silicone materials [...]
