Thank you for your annotaions. I am aware of the limits and temperatures of that material, but we are doing some research with thermoplastic base materials which won't survive standard solder paste reflow soldering. And beside of using conductive ad

Hello All! I've been asked to change a current design using a shield. Currently we build it by using silver epoxy adhesive to make electrical connection. Just wondering if anyone out there has a experience with using surface mount clips that hold

I was somewhat involved with Kermit Aguayo during his work on the SMA-void problem, as I was with one of the SMA suppliers at the time. I recall the problem being related mainly to absorption of moisture by the uncured adhesive. Some SMA formulatio

Go for it!!! You were unspecific, but adding mask to a completed board could cause: * Increased paste thickness, if you have double thickness of solder mask. * Wrinkled and lifted solder mask under the component, if the solderability protection of

Dear Colleagues Does anyone know or care to share any information as to typical torque values ( N/cm ) for components that have been placed using screen printing surface mount adhesive, using a plastic stencil ? Are there any industry set shear test

Hi, We occasionaly have problems with some of our panellised boards breaking away from each other. The section joining them is very small and makes the assembly weak. The boards are normally broken off during our through hole process (bad handling)
