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 [...]

As a manufacturer of polyimide tapes and films (generic version of Kapton), we are often asked whether we can make custom-made shapes and sizes to meet advanced packaging requirements. The requests come from design engineers looking to incorporate polyimide films into their designs, often to create an insulation layers between two parts. CAPLINQ offers this [...]

Dry etching refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a bombardment of ions that dislodge portions of the material from the exposed surface. Unlike with many of the wet chemical etchants used in wet etching, the dry etching process typically etches directionally or anisotropically. [...]

CAPLINQ does work with an independent testing facility who can carry out this the UL Certification, but then CAPLINQ normally requests either a commitment for a certain order quantity (ie. 100 rolls), or that the customer pay for the testing.

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 [...]

Polyimide Tape (the generic version of Dupont© Kapton Tape), typically comes in various polyimide thicknesses. These thicknesses are generally labelled as 1-mil, 2-mil, 3-mil or even 5-mil thick polyimide tape. Each of these variations serves different purposes and is therefore used for different applications. Of course, the thicker the polyimide film used, the more expensive [...]
