Laser Machined Kapton(TM) Parts

BEST Inc. can supply you with custom machined Kapton(TM) parts.

We have been involved in laser machining of Kapton (TM) and adhesive-backed Kapton (TM) for nearly 10 years and have the processing and sourcing expertise for your custom-made laser-machined Kapton (TM) parts.

BEST has the ability to machine parts as small as a few mm up to several inches in size being able to define features as small as a few mils in different types and Kapton(TM) thicknesses. While we have several standard adhesive-backed and non adhesive-backed material thicknesses in stock,we can also machine materials that you supply acting as a machining service provider. We can also package this material, add other value-added services as part of the machining services or simply just machine your parts.

We can take in a variety of file formats including but not limited to GERBERs, dxf, dwg and other vector file formats.including .ai, .eps, .pdf and .svg file types. If we perform any file modifications we will send you an approval drawing in a mutually-agreeable file format so you cna approve the files prior to us machining the parts.

BEST has experience machining a  variety of different parts. Typical parts that we have machined for the electronics assembly and rework areas include prototype SMT stencils, rework stencils, masking stencils and reballing stencils. We have also machined specialty Kapton(TM) shapes for heat shields for specialty component shapes and sizes. In addition we sometimes custom cut shapes for protection of components in the conformal coating or wave soldering processes.


Laser machining has several advantages over die cutting of Kapton™ to make precision parts. First of all the die cut parts require a die, which is tooling requiring a non recurring engineering fee. In addition, dies can take anywhere from a few weeks to two months; precious time not allowable in some projects. Furthermore, most die sets can only maintain gross tolerances of 0.005” whereas laser machining can hold tolerance down to 0.0005” inches or ten times the precision. Lastly, the die itself also is a mechanical tool meaning there is an associated life to the tools as well as lack of clean cut surfaces as the tool wears. For these reasons the precision and speed of delivery for laser machined custom Kapton™ parts is the way to fabricate parts made of this versatile plastic material.


We have Kapton(TM) in stock in many common sizes from 2-6 mils. In addition we have adhesive-backed Kapton(TM) in stock in 4-8 mils with high temperature adhesive able to withstand reflow temperatures.

    Parts were made well. There was a bunch of back and forth in the beginning of the process but they/we got it right

    We are always under the gun to get projects out very quickly. Quality of the work was good. People were good. It can and will always need to be faster
