The Probe Card Interface Assembly (PCIA) can interface with any wafer size. The PCIA is robust and trouble free, it is quite reliable. It fits into the same opening as the 9.5″ RC-2 carrier ring used by most prober manufacturers for rectangular probe cards.
Test Structure and Software for Measuring Thin Film TCR
This product offering consists of test software, a GDSII compatible test structure, testing of at least one wafer, and one day of training at Reedholm. It can be ordered with a new Reedholm test system or retro-fitted in a Reedholm system which has at least three VFIF’s and a DMM-16.
Use of Low TCR Films
Performance of many precision integrated circuits is dependent on low temperature coefficient of resistance (TCR) resistors. For example, analog to digital and digital to analog converters typically use low TCR films in ladder networks and as feedback resistors. Some signal processing IC’s make use of low TCR films for gain setting. TCR values, matching, and stability are extremely important in such applications.
Our progress continues. It has been a busy last couple of months with systems being shipped all over the world.
On the business front, we are busy at work completing this year’s CARTA corporate valuation paperwork. Everyone that you work with at Reedholm Systems is a shareholder in our entity, which means they have a stake in your success too!
This month we are promoting a couple of test accessories that we hope are of interest:
Reedholm’s PCIA has proven to be a workhorse for customers, dramatically reducing if not eliminating cable failures that otherwise result in a down test system. And these are matched by simple high-performance probe cards that are wafer size independent. The PCIA is normally shipped with Reedholm test systems but can be shipped for use with just about any test system while delivering sub-pA performance if desired. The probe card end remains the same, however a cable and connector that that matches up to other brands of testers needs to be incorporated.
The other test accessory is the automated TCR capability. Comprised of a test structure and automated and integrated test routines, this allows customers to gather comprehensive TC data in production.
Finally, we are updating our website with the availability of spares or replacement modules, both new and refurbished. If not immediately available, online ordering will be in place by the end of the year.
