I've never seen this before. Today, I got this tombstoning on Tantalum Capacitors (Okay, I saw that before) Here's the part that seems weird to me: -They didn't tombstone onto a termination - they went onto their sides! That's right, both terminati

I am looking for data on the yield of printed circuit board assemblies so that I can judge if our SMT line is performing up to typical industry standards. Following I will describe the details of the assembly and what our yield has been. Each board

I've been assembling thousands of boards for dozens of customers over the past 5 years with 0402 chip components. 85% can happen very easily even with newer equipment. Defect challanges with 0402 packages is almost always tombstoning. Capacitors abou

Hello, I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is
