Sean I have to agree with Dave on this issue. As a frequent reader of this forum I appreciate it when company reps clearly note their affiliation, but I like it much better when they are also willing to identify the companies they compete against, "o

CMI International says, there are five basic, non-destructive methods of determining coating thickness. Each method was devised to achieve cost-effective, accurate, and repeatable results. Those methods are: * X-Ray fluorescence * Eddy-current * M

Frank, Don't know about point 1 but if they don't fall off I don't worry about it. If they do fall off it's generally because someone has mishandled them before the wave, like shoving them into racks and the like. If they have fallen off and you can'

I have just been assigned to look into the ionic chromotograhy test on our PCBA but I have zero knowledge. Could anyone help to explain what is this test about? Is it a) a destructive test? b) What is the measurement unit of this test? c) What is th

I agree that solderability is THE issue, but we choose not to get into that pissin' contest. [We don't like the selected test method, either.] We believe that our coating thickness spec provides: * Solderability level that we seek. * Repeatable tes

I'm with Steve and flying probing. As long as you are testing the capacitance of the cap in the circuit and not of the cap itself you'll get a pretty good indication. Most are going to be 10nf and 100nf decoupling caps at that size so quite easy to

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus

IPC-TM-650 is free downloadable test methods defined by IPC. Check their website. http://www.ipc.org, and look for the free downloads section. The manual is divided into several subcategories, and I believe under mechanical test methods there are
