Prober- Production Clamshell Bed of Nails Testers All Prober Production volume test fixture with swappable test plates, front and rear panel inlays, and multi-testing compatibility with process carrier pallets. PCB / Circuit board assembly test / repair / rework. This Week In Security: SolarWinds And FireEye, WordPress DDoS, And Enhance! This technique goes by a few names, but can also be done using flying probes – this removes the need to create the bespoke bed of nails fixturing. Without needing to use alligator clamps or anything else labor-intensive to test, this simple jig with all the test points built-in means that each board can be laid on the bed and tested to ensure it works properly. Meanwhile, we have a number of PCB assemblies with $10k worth of silicon on them that we can’t use. Whether your need is a simple manual bed-of-nails test fixture or fully automated bed-of-nails test fixture, we have the right solution for you. There are other ways of testing PCBs after production, too, but if your board doesn’t involve any type of processing they might be hard to implement. For PCB-based subassemblies and complex components. A bed of nails tester is a traditional electronic test fixture. For more details, please see our. Mechanical Press Fixture Kit #9560 The 9560 Mechanical Press is a reusable fixture kit that can be customized with different fixture plates for flexibility to test multiple products. First, the clamshell lid is brought to rest directly above the UUT(s). There can be space under the fixture for electronics to support the test requirements with additional electrical access thru the Front or backside of the fixture. Swappable test plates provide the ability for one fixture base to … I’ve seen insertion machines that had a tester on the rig for passives on the ammo pack tape reels. Resources. We were doing good if we got 80% coverage on a given board. make sure to add holes/indents for guidance pins. Not yet, but someday we plan to provide fixtures for ICT and flying-probe like tests. When they arrived they were actually precision cross point head micro spring loaded PCB test bed pins. Ideal for failure analysis, fault localization, or for use under a microscope. Cheap. Early Flying Probe technology came out in the late 80’s and Flying Probe technology has advanced quite a bit. I’m hoping we won’t have to sacrifice a board for sectioning / electron microscopy, but it might be the only way to resolve the issue. Our smallest and most compact test press for low-medium pin count devices and smaller PCB modules. Interface modules and can be removed from the test press base quickly and easily. Companies like ZEHNTEL, Teredyne and others designed and manufactured ICT or In-Circuit Test platforms and they all used bed of nails type fixtures. A low cost option for any application Simple, low cost functional test boxes can be customised to virtually any application. Additional integration options are available for custom features such as RF shielding, pressure, temperature, light regulation, the inclusion of driver components, and more. We used an assortment of ZEHNTEL 410 and ZEHNTEL 810 testers in our shop. Had good success with their work. I work for a CM and we use both on a routine basis for state of the art products. Neil Lambeth has added a new project titled The X-PC. Our fixtures are for Printed Circuit Board Assembly Functional Testing (PCBA FCT), using a bed-of-nails test fixture. https://www.youtube.com/watch?v=N__yGuSz7PM, “you’re going to need to test all the PCBs after they’re built”. Constantly disassembling modifying and reassembling a normal bed of nails test fixture over and over again can be a major disaster with wire breakage and test pin bending issues. Behnam liked PCB art dithering experiments. Mukesh Sankhla has updated the project titled DIY RGB Tube Lights. Single lever operation and 100% vertical compression makes the manual test press an ideal solution for PCB, hybrid module, and high pin count device-level testing when complex test requirements cannot be met with a test socket and breakout board alone. I never followed up to see that everybody was doing that or if it was jsut one guy better than the next. Probes top bottom and all 4 sides. I’m an old in-circuit (bed of nails) Test Engineer. And board shops know it’s hard to pin the issue on them once the parts are placed and the boards go through the reflow oven. Gold plated with carbide tips. There are many very expensive solutions to that but you will learn here how to create your own bed of nails tester by simply using a 3D printer. This adaptability allows for rapid product changeover in engineering and production test environments. The 410’s had HP desktop computers with HP Basic while the 810’s has X80 computers loaded with UNIX. Do you need help finding a test solution? google ICT testing and you will find more on this subject. The fixture contains a multitude of small spring-loaded test pins that protrude from a wide base that can secure the PCB; the bed of nails test method gets its name from these protruding pins.
