General Precautions for Using DOTITE™
DOTITE™ is...
DOTITE is the brand name and general term for Fujikura Kasei’s resin-based materials for electronics. Because electrically conductive materials make up the core of the DOTITE lineup, we refer to them collectively as our Electronics Materials.What is it?
DOTITE is marketed as “electrically conductive paste,” and it can be used to provide electrical conductivity to a variety of materials. Generally, when in paste form, it isn’t conductive - but through the process of “application⇒ drying or curing” to form a cured film, it is able to conduct electricity.
Because it contains silver, DOTITE is also known as “silver paste”, but depending on its properties, these materials may also be known as “electrically conductive adhesive,” “electrically conductive paint,” “silver ink,” and other names depending on the industry.
Choosing the Right DOTITE™ Product
We provide a variety of DOTITE products, so we always check the user’s requirements to determine the right material for their project. Of course, you can always check our catalogue below or contact a sales representative with any questions.We’ll ask about your requirements for electrical conductivity, application method, substrate, and what role DOTITE will it play in your final product – how will you use DOTITE?
【Electrical Conductivity】
We measure conductivity as volume resistivity (Ω・cm), which can be compared to other products or metals (for example, silver has a volume resistivity of 1.62 x 10-6Ω・cm).
【Application Method 】What is the application method? What shape will it be? Applicability, resolution (large or small area, fine line, &c.), and cost are some factors to consider. If you have an application method in mind, the material’s viscosity is important; but if any application method is ok, then the shape or resolution of the finished product must be considered.
【Target Substrate 】The paste’s adhesion to the substrate and the curing/drying temperature need to be considered.Additionally, the texture of the substrate surface is a factor.
【Function and Use 】Let us know in detail the properties that are necessary for your application and we will offer the best material for your project.
Adhesive：“Brazing or soldering replacement,” etc.
Cured Film Durability/Reliability：Environmental resistance, solvent resistance, abrasion resistance, bending resistance, etc.
Application：“Electrode,” “circuitry jumper/crossover,” “bump interconnect,” etc.
General Precautions for Using DOTITE™
・Be sure to mix thoroughlyBefore use and/or after dilution, the DOTITE material components may separate. Using a spatula or similar tool, be sure to mix the material thoroughly. Continue for 2-3 mins. after the material appears to be uniformly mixed.
・Clean tools and equipment after useThe appropriate cleaning solvent is different for each of our DOTITE materials, so check the product information for the correct solvent to use.
・Other precautionsFor other usage precautions, chemical composition, and safety information, see the material’s SDS documentation.
