A bed of nails tester is a traditional electronic test fixture which has numerous pins inserted into holes in an epoxy phenolic glass cloth laminated sheet (G-10) which are aligned using tooling pins to make contact with test points on a printed circuit board and are also connected to a measuring unit by wires. Compact, portable, all-inclusive, and easy to use. Our most popular benchtop manual test press for testing high pin count devices, panelized PCB modules, and large complex PCB boards. Thank you for sharing you knowledge! The test fixture can be designed to use little or no external instruments. At the moment, the contract manufacturer and the PCB house are pointing fingers at each other. More reliable than vacuum operated fixtures, they are a good choice for functional testing on a smaller scale. The test bed looks like a bed of nails as well, hence the name. Sadly, this may make the board much larger due to the holes. They land probes on components and can perform any measurement you want. I guess I reread your comment and noticed that you weren’t saying what I thought you were saying :). Solderability issues? 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. There are many different manufacturers for these fixtures, with varying costs and durability. If you have whetting issues it could be either, and it’s hard to prove who once the parts are places and the solder reflowed. So, if your profile uses brand X solder, nitrogen or no nitrogen have them share solderability data for like boards in their process. If they do and they show no issues with other’s products then it’s the board house! posted some links (awaiting moderation), see Early ICT test sets came out with guarding, a technique that mostly zero out parallel paths. Resources. Clean, streamlined, and robust designs can be made adaptable to accommodate a multitude of standard and custom printed circuit board footprints. All of them apply chemistry profiles to their customers.

The 410’s had HP desktop computers with HP Basic while the 810’s has X80 computers loaded with UNIX. Mukesh Sankhla has updated the project titled DIY RGB Tube Lights. While it might be tempting to start soldering a circuit together once the design looks good on paper, experience tells us that it’s still good to test it out on a breadboard first to make sure everything works properly. Standalone or complete with embedded test systems. The alignment is usually solved by inserting a plastic board (such as POM) with precisely drilled holes between the DUT and the PCB beneath. The leader for over 20 years Test-X offers you unmatched quality for value products and services. Cheap.
