Thanks for the information. davef, I will search for and review the Ion Chromatography for Ionic Cleanliness test method. This definitely is the test I want to perform. Do you know what the IPC specification is using this test method? The outside

Scott: Sounds like fun: � Solder joint strength in pull/shear varies with lead geometry, solder volume, lead metal/metallization, and the test method. � Among things, IPC-TM-650 talks to getting pads off-of boards. For instance: Method 2.4.8 is for

Hi, cool news! I'll try to cook some as soon as I get some experiment material. Thank you for the test method. Rgds

Not aware of anyone that builds anything like the C3 selective extraction system. I know there is a move to develope and IPC test method for this process, but it's not there yet.

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

Just wanted to ask what is the correct test method i need to do to ensure that my cleaning solvent is still OK to use. This is in particular for stencil cleaning,carriers, pcb etc. I am using a jet cleaner with recirculating solvents.

I need to perform shear tests on components that have been glued prior to wave soldering. Can any one recommend a shear tester and some standardized info on testing? We have had problems with poor glue bonds and would like to implement a test metho

This was the test method mentioned to me about 5 years ago, to use for testing for black pad, when we were evaluating the use of gold immersion for the first time. It is not practical for testing the entire surface of a PCB, but it should work well

There is an IPC test method involving a tape test, which you can try for a start. Look at the IPC TM-650 free on the IPC site. Black pad occurrences are much reduced, but I don't believe you can say they never happen, even to the better board houses

Here's your test definitions [clipped from the dictionary in the fine SMTnet Library]: * Test, Automated. Computer controlled electrical testing of parts, assemblies, or finished products. * Test, Built-In (BIT). An electrical testing technique whi
