| I am looking at using a IMS substrate for a new product can any one tell me where I can get some good information on this product??? | Bergquist have helped us in the past with trials.

Dave, Ceramic sheets of that size are not always flat and as a result will sometimes crack when clamped along the full edge. Point clamping will hold the substrate secure for placement. If you are not processing in a pallet make sure that you have

When I said "In this area, there is no difference between your experience in ceramic substrates and PTFE substrates." I was referring to the area we were discussing ... gold plating. I am sorry if you thought I ment than the wire bonding process wa

I'm trying to get an even solder coating onto a retangular shaped ceramic substrate (5.0mm x1.83mm), but the solder tends to pool on the short side of the substrate.

If the goal is selective soldering (not to raise the substrate temperature too high), consider the use of microwaves. Our company has been working on this technology for selectively bonding substrates. For example, we use the process to bond ROHS met

We see delamination at Mold compound to substrate interface when tested for MSL3. We haven't tested the substrate for cleanliness. Can you please suggest methods for this? thanks, arun

Hi, I am also facing the same probelm. I assembly a substrate with a thickness of 0.30mm and the board warp after reflow. If I bake the substrate at 125 Deg C for 2 hours will it help to solve this problem? Thanks

Polymide is like a sponge and absorbs moisture much faster than rigid substrates. Pre-bake your substrate for 2-4 hours at 125C and perform your soldering within 1 shift thereafter or seal in moisture barrier bags.

Hi I am using an old Camalot 1818 to dispense squares of epoxy on a substrate. Does anyone know if it is possible to do an array of squares across the entire substrate rather than individually entering the coordinates of each square? Thanks!
