Contacting Solutions for Reliable, Repeatable Test ... - Johnstech

Johnstech ServicesJohnstech offers a full line of technical services to assist you in achieving thehighest level of performance. One of the services that is particularly powerfuland effective for IC package testing is Johnstech’s use of HFSS and ADSsoftware to model the electrical performance of the Contactor and the interfaceto the device and load board pads. This provides direction to select the bestContactor ground configuration for the application and to design the optimalload board trace layout, which are both vital to optimizing the overall systemelectrical performance.Contact JohnstechTo learn more about Johnstech’spatented solutions and servicesthat maximize your precision analogtesting performance, reduce yourengineering risk, and providerepeatable production test results,contact your local Johnstech SalesRepresentative at www.johnstech.com.Electrical Specifications (NiPdAu Configuration) Pad ROL 200 Series Pad ROL 100A SeriesInductance: Self: 0.55 nH 0.37 nHMutual: 0.24 nH0.15 nHCapacitance: Ground: 0.35 pF 0.08 pFMutual: 0.12 pF0.03 pFS 21Insertion Loss: -1dB @ 18.5 GHz -1dB @ 40 GHzS 11Return Loss: -20dB @ 5.8 GHz -20 dB @ 18.3 GHzS 41Crosstalk: -20dB @ 29.5 GHz -20 dB @ 33.5 GHzCurrent Carrying Capability: 2.8 A 2.6 ACompliance: 0.20 mm 0.175 – 0.20 mmContactor configuration also available for Matte Tin packages. See website for specifications.Pad ROL200/ROL100A SeriesPerformance ComparisonThe Low-Force XL-2 Contacts areavailable for both the Pad ROL100Aand Pad ROL200. The choice ofContactor usually depends on theelectrical performance required for thedevice under test. Here is a summaryof the performance differencesbetween the two products.ApplicationsThe Pad ROL100A and ROL200 are used extensively for RF/wireless, precisionanalog, and high speed digital devices that require the highest electrical andmechanical performance for engineering and production applications. Offering thehighest electrical performance, the ROL-series lowers your engineering risk andallows you to set tighter guard bands. With the consistent results it provides, ROLseriesprovides the robust mechanical performance and site-to-site repeatability inproduction applications to increase your yields and maximize your OEE.SummaryThe new Johnstech Low-Force XL-2 Contacts for the Pad ROL100A and ROL200Contactors stand up to the challenges of NiPdAu and NiPd packages. Furthermore,the price of the XL-2 Contacts has been significantly reduced compared to theprevious Eco-1 Contacts. The extended contact life and lower spares costs willlower your overall cost of test.
