Probe Card Adapter Kit  
LMS-18 Probe Card Adapter Kit is compatible with industry standard 4.5 inch probe cards. This can be used for  fixtures to test DC through microwave DUTs, thin film or MMIC.
A J microTechnology probe station with a probe card adapter is a low cost test station to perform engineering check out of production probe cards and production test programs.
The probe card adapter can be used on all probe stations, JR-2727 Personal Probe Station and JRr-2745 Manual Probe Stations. 




PCB Holder/Chuck
High frequency characterization of Surface Mount Components and engineering test of RF/Wireless subassemblies is usually on double sided PCB substrates. The LMS-10 PCB Holder/Chuck allows for 0.5" to 2.25" wide by up to 5" long and .030" to .1" thick PCBs to be held in place for precision probing. There is 0.15" min. clearance underneath the PCB. Can be used on both JR-2700 Test Fixture and JR-2727 Personal Probe Station. 



CPW to Microstrip adapter substrates

Adapter Substrates for the precision test of microstrip components 

ProbePoint Adapter Substrates

 Introduction to Adapter Substrates

ProbePoint Adapters Substrates are used to create test fixtures that coplanar or coaxial microprobes, either Picoprobes from GGB Industries or ACP/FPC probes from Cascade Microtech, Inc (CMI), can be used to precisely make electrical measurements. Because of the precision and repeatibility of the adapter substrates and the availability of calibration substrates for direct calibration of the adapters, metrology grade measurements can be made to 60 GHz and above. This makes these adapter substrates a useful tool for engineers and scientist who characterize various microstrip and surface mount devices(SMD) for "wireless" and microwave circuit design and analysis. 

ProbePoint Adapter Substrates are thin film ceramic components available in three different thickness, 5 mil 10 mil and 15 mil. An overview of the products is contained in the Introduction to Adapter Substrates. 

ProbePoint Microstrip Transmission Line Substrates are used for package characterization and interconnection of multichip MMIC devices. Standard and custom lengths up to .5" are available in either 5 or 10 mil thickness alumina. 0.1", 0.18", 0.25", 0.5" are available from stock. Custom lengths are three week delivery. 

Both standard and custom Calibration Standards available for SAW SMD packages. Replacement calibration substrates available for the repair of selected ICM fixtures.
