Board Design Capabilities
We offer placement and routing services for various types of boards such as probe cards, load boards, DUT, and handler interface boards. We ensure proper impedance and length matching for precise testing. We design prototype load boards for both manual and fully automated handler applications. Our expertise includes various types of probe cards such as epoxy cantilever, blade, WLP, and vertical contact, including COBRA probe cards. We also design burn-in tests, ESD, bench, and reference boards for different types of testing. We specialize in low power and high-speed testing for digital, analog, mixed signal, and RF devices. We use high-speed layout techniques to reduce distortion, delays, and noise. We carefully select PCB fabrication materials to ensure boards have less inductance and higher signal strength, and we have industry-wide knowledge on test sockets, probers, handlers, and docking systems. We support various tester platforms like Verigy, Advantest, Teradyne, LTX-Credence, Yokogawa, etc.
Board Design Experience
Our design process prioritizes signal integrity, utilizing schematic-driven and layout techniques that follow IPC standards, such as IPC-2221, -2222, -2223, and IPC-7351. Our experienced team is well-versed in a range of manufacturing processes, including DFM, DFA, DFT, and ICT, ensuring the best possible product. We incorporate precision analog and mixed signal integration, utilizing edge-coupled and tandem differential pairs, and carefully consider skew matching based on signal rise time. Our board stack-up is optimized with controlled impedance for micro stripline, stripline, and dual stripline stackups. For faster routing, we use our in-house tools, which result in aesthetically pleasing designs with minimal vias. We also employ advanced routing techniques, including blind and buried vias, micro-via and via-less routing, constraint-driven placement, and routing.

Interface Board Design
Our team has extensive experience designing probecards for various applications and providing services to leading probecard vendors worldwide. We have a strong track record of delivering high-quality designs on schedule, regardless of complexity, which has earned us repeat business requests.
Designing probecards with high pin counts and densities is a routing-intensive task that requires meticulous attention to detail. Routing signal and ground traces typically accounts for more than 50% of the total design time. Achieving board planarity requires evenly spacing the traces across the spider area, and their lengths must be matched to zero tolerance to ensure optimal performance. Completing a design of this complexity in a short period requires significant manpower.
At Caliber Interconnects Private Limited, we have the expertise to overcome the challenges of designing a probecard in a short period. We accomplish this by extending the capabilities of EDA tools through our customization capabilities. Our in-house software team has developed intelligent software tools and utilities that enable designers to achieve fast turnarounds in each design process. Our entire design process is tool-driven, and we continuously innovate new tools to facilitate manual routing. Our team can route 2000 traces in a day, enabling us to meet customer-specified timelines.

Design Highlights
We have extensive experience in designing a wide range of probecards, including fine pitch, high density, multi dut diagonal, and RF cantilever probecards. Additionally, we have designed vertical probecards and space transformers, MLO/MLC substrates, low leakage parametric probecards, blade cards, motherboards, and RF probecards. We also have experience in designing wafer sort performance interface boards and motherboards.
Our expertise extends beyond design to include electrical simulation of probecard and probe pins. We are able to keep the layer count low and achieve zero tolerances routes, resulting in efficient and effective designs. We have designed boards for high frequency memory, logic, and RF devices, and have an in-depth understanding of tester instrumentation and prober technology.
Load Board Design
A properly designed loadboard is critical for testing ICs as it significantly reduces the risk of test pass failures. At Caliber interconnects, we specialize in creating high-performance loadboards that allow for accurate testing of your device as per your test plan. Our experienced ATE testing engineers are skilled in designing flexible ATE test schematics that can accommodate future test requirements.
Our loadboard design expertise covers a wide range of devices, including SoC/Mixed signals, LCD, Memory, Image sensor, Power, Digital, Analog, and RF devices. We have also designed boards for high pin-count BGA devices up to 2016 with pitches as small as 0.4mm, and devices operating at frequencies up to 28Ghz.
We apply high-speed design techniques and conduct signal integrity analysis to ensure the highest possible performance. Additionally, we have access to tester template libraries, socket and component footprints, and handler libraries to further streamline the design process.
Our knowledge of handlers and tester instrumentation allows us to ensure zero tolerance for both high-performance and low-speed digital signals. We have extensive experience working with popular ATE systems, tester instrumentation, handlers, and sockets.
