TECHNICIAN is a probe card planarization and measurement system consisting of a computer, custom Windows operating software, a precision measurement unit (PMU) . Technician is available for customers who wish to add these advanced capabilities to their existing planarizing station or the Technician can be combined with the LEVELER another product of Beijert Engineering. Planarization is critical to insure optimum test probe contact and maximize test yield. Increasing device complexity coupled with increasing quantity and density of probes requires a more complete measurement solution. Technicianís PMU also measures and reports contact resistance and probe to probe leakage.   

Operating Concepts  

Technician is intended to enhance the capability of another planarization system. Technician software is user friendly and is completely intuitive, operating in a Windows 98 environment. 
System setup is as simple as pointing to a probe and touching each probe to give it an identity for a reference profile. Unlike traditional light boxes, Technicianís display provides a relational probe location display which allows the user to assign a probe on the probe card to a pad displayed on the monitor.
The pad location, as displayed, will reflect the relative location of the probe on the card. This relative location assignment makes it easier for the user to quickly identify and adjust the correct probe. 

Planarization, Contact Resistance & Leakage

Technician can measure probe planarity, probe to probe leakage and individual probe contact resistance. The Windows software is flexible and allows the user to apply filters to measure all parameters or to select specific tests for a probe card. The user is also able to select the display mode to display only failed or near failed probes, or to display both in two different colors.   

Precision Z-Measurement  

Technician includes a precision Z axis measurement capability. A precision digital linear gauge is mounted on the LEVELER and is interfaced with the central processor. Digital readout is available on the gauge or on the monitor display. The digital readout is user selectable between inches or mm.  

Graphic Display  

Technician provides a clear, easy to read display of individual probe parameters including a graphic display of probe planarization and a relational contact pad map to aid with individual probe adjustment.     
Probe contact and the quality of the contact is displayed on a pad map in color. The relative location of the probe is reflected in the pad map. Grey indicates a probe but no contact. Blue indicates contact but with marginal result. Green indicates a passing contact which is within specification. Red indicates failed contact, which is out of specification. The threshold settings for these results are programmable by the user.

Clean Concise Reports  

Technician provides clear concise reports in a universally familiar MS Excel format. 
The reports can be printed to the screen or sent to a laser printer for permanent documentation


Current Windows PC.  

Measurement Center  

All measurement electronics and I/O connections are contained in a robust electronics enclosure. The measurement center supports up to 256 channels in 32 channel increments. The basic Technician starts with 64 channels. Additional 32 channel boards can be added by the system.
