Advanced digital printing of electronics - Prototyping of printed components

Do you consider integrating an ultra-thin humidity sensor in your product? In need of a flexible thermocouple? At Danish Technological Institute (DTI), we can help you design, print and surface mount on electrical circuits and sensors directly onto flexible and ultra-thin substrates.

We take you through the entire process
Below is a list of the services we provide, which can assist you on your journey to component prototyping.
 

C033_NRN_#1_5_1Techno/economic assessment – Before we start designing and prototyping, you need to know whether printed electronics is the right fit for you. In our assessment we provide a Go/No Go answer of whether or not we can provide you with a solution. If there is a Go, we then provide you with a System Architecture (SA) and preliminary bill of materials (pre-BOM). Through these we can provide information about what the solution will entail and estimate the material and component costs of an eventual final prototype

 


Design & prototyping – Once we have a positive techno/economic assessment, we bring the idea into our pilot lines. The first step is to design print layouts, where after we have several options for prototyping.  At DTI we have both a fully digital advanced deposition prototyping pilot line and a screen print pilot line. The full specifications of our pilot line equipment are shown below.
