CINDAS

What does CINDAS stand for?
The Center for Information and Numerical Data Analysis and Synthesis

How long has it been in operation?
For over 45 years

What is TPMD?
The Thermophysical Properties of Matter Database

What is MPMD?
Microelectronics Packaging Materials Database

What is the TPRC Data series?
A 13 Volume collection of data on thermophysical properties for metals, alloys, oxides, fluorides, carbides, minerals, semiconductors, polymers, etc…It stopped being updated in print form in the late 1980’s. The TPMD is derived from these handbooks and is being continually updated with additional data.

Is the CD-ROM still available?
The CD-ROM is no longer available.

What is a CINDAS data curve?
A data curve is essentially a graph. It is a visual representation (a plotting) of a table of data illustrating the response of a property with incremental changes – usually with a dependent and independent variable. The line connecting the plotted data points can be curvilinear or rectilinear but most often is curved

The independent variable (e.g. Temperature (deg. K)) is usually plotted on the horizontal “X” axis.

The dependent variable (e.g. expansion or contraction of the material being tested) is plotted on the vertical or “Y” axis

A data point is that point in the matrix where a specific temperature gives a specific expansion or contraction.

Examples of dependent and Independent variables – Plotting the height of individuals on a crowded bus.
The horizontal (X) axis plots the independent variable. In this case it is height in increments of feet/meters. It is independent because we chose it.
The vertical axis (Y) would be the number of individuals that represent that height which meets the parameters given in the horizontal axis.

For example we can have one curve representing individuals or two curves representing women and men and a third representing children, etc. This is represented by different colors in CINDAS.

What is microelectronics packaging?
The design and assembly of microelectronic components into packaged assemblies that perform one or more functions. A typical example would be the various circuit boards in a computer. The MPMD contains data on a large portion of the solders, adhesives, coatings, etc. used in this industry.

How many different materials are covered in each of the databases?
The TPMD contains over 5,000 materials and over 50,000 data curves.

The MPMD contains over 750 materials and over 15,000 curves. The MPMD has fewer materials but has many more diverse properties in addition to the thermophysical properties.

What is the main purpose of using CINDAS Databases?
As an aid in identifying and assessing the appropriateness of materials for engineering applications.

How often is it updated?
Updates occur regularly. In the past year there have been three major updates to the databases; the next major update is scheduled for July of this year

Why CINDAS and not other similar services?
CINDAS is reliable, flexible and critically evaluated. The CINDAS works have been the bible for thermophysical properties for over 4 decades.

Are free trials possible?
Trials can be instituted on an individual basis, although a demo should indicate the suitability of the product for a customer’s needs.

How much data is on the demos?
Approximately 1% of the total available data is represented in the demos.

Can I compare multiple materials?
Yes, multiple materials and data sets/conditions can be graphed for comparisons.

Is the usage unlimited?
Yes – through the CSA Illumina Platform.

Can the data be exported into an Excel spreadsheet for example?
This is a planned future enhancement to the databases.

Are there other databases in production?
Yes. A database on aerospace materials is planned for next spring.

How does a CSA customer access the CINDAS databases?
By either selecting the databases directly from the resources page – whereby they will have full CINDAS platform access or through a search of the CSA Illumina files they are subscribed to.

Is CSA the exclusive distributor?
Yes – CINDAS will refer all new prospects to CSA.
