While you would use a breadboard for prototyping, the platform you’re going to need for quality control is called a “bed of nails“. Interface modules and can be removed from the test press base quickly and easily. When they arrived they were actually precision cross point head micro spring loaded PCB test bed pins. The most popular method for in-circuit testing is the use of a bed of nails fixture. Sadly, this may make the board much larger due to the holes. Our Press Fixture Kits are designed to provide precise, bed-of-nails contact in both R & D and production environments. Thy his type service is valuable when you start purchasing multi layer boards. I’m an old in-circuit (bed of nails) Test Engineer. For years – from the very late 1970’s to far into the Surface Mount era, In-circuit was THE test platform for circuit cards. The nails are mounted in a pattern specific to conductive pads on the target board. Early ICT test sets came out with guarding, a technique that mostly zero out parallel paths. Or the baking (or lack thereof), or perhaps the PCB house put the intern in charge of the etchant. The test bed looks like a bed of nails as well, hence the name.

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. Second, the lid presses down vertically and evenly across the UUT ensure alignment and even pressure to prevent damage to the UUT and pogo pins array(s). Probes top bottom and all 4 sides. The type of issue you are explaining are favored challenges for my consulting business and I usually tackle these near free. Compact, portable, all-inclusive, and easy to use. Neil Lambeth has added a new project titled The X-PC. The test system can then make measurements between these points. Not related to solder per se, although the temperature profile during soldering may have had something to do with it. 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. Single-site or multi-site configurations offer rapid device loading and unloading. The term bed of nails is a rather graphic description of what many fixtures look like, having a large number of test points or probes proud of a board that holds them in place. 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. Nahhh, Alice Cooper. Designing a DEV260 Fixture; Assembling a DEV260 Fixture; Test Instrumentation for a DEV260 Fixture; The first part of the DEV260 Fixture Series covers designing the mechanical bed-of-nails fixture which includes selecting test probes, guide pins, pressure pins, and positioning the DUT. The bed of nails style interface module is a UUT-specific design that routes signals from your UUT out to other components in your test configuration or directly to connectors of choice. For PCB-based subassemblies and complex components. I guess I reread your comment and noticed that you weren’t saying what I thought you were saying :). 135 East Main Ave Suite 130 Morgan Hill, CA 95037, For privacy reasons Vimeo needs your permission to be loaded. Test Presses ensure evenly distributed vertical compression force is applied to the UUT. A bed-of-nails test fixture is a pod with a number of test nails mounted on it. The nails are meant to probe different points on the PCB placed in the test fixture. Compact benchtop test presses consisting of two core components: dedicated bed of nails style interface module to engage with your UUT and a standardized test fixture base that houses the interface module and provides vertical compression force when closed. Manual test presses provide full capabilities for test point contacting both topside and backside of the Unit(s) Under Test. Solderability issues? 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. Even with 100% supply outgoing inspection it is still a good idea to do your own tests, at least on a random sample.
