CAPLINQ has been working with a number of LED customers lately, and many of the same questions keep coming up regarding the Shin-Etsu X35-186H-1, a screen-printable silicone suitable for phosphorus suspension in LED applications as well as other silicones for LED assembly. Below is a list of some of the most frequently asked questions with [...]

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 [...]

Same size die stacking is different from other die stacking in that the bondline thickness must be a minimum of 60µm – 80µm high to ensure enough wirebond-loop height. In short, there are four proven ways to achieve this: Dummy-Die silicon interposer (a space-consuming, expensive and redundant method not discussed here as it is a [...]

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 [...]

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 [...]
