I have seen this before, our problem was palladium termination of this component. We could not change suppliers so we use a "reverse homeplate" stencil design to put the majority of paste directly underneath the solder terminations of the component

Fitness-for-use is a very important aspect of a squeegee. The most delicate and important element of the squeegee is the blade. Regardless of how you store 'em protect the blades! I know MPM has blade covers bud don't know about DEK. I'm sure they

We test Parts and Components to IPC J-std-002/003. We also use a wetting Balance tester to determine solderability. We also test with SERA. We use ROSA to electrochemically revert the components back to their original state. Need more info ... email
