Hi! Why positive displacement technique cannot be used for underfill dispensing? Which is the best technique to dispense underfill?

Check with the adhesive manufacturer. Not all underfill material is reworkable. Brian

Is there a tool to check for voiding in a Underfill process?

Does the customer understand why underfill is used? I don't think you will gain anything on this QFN.

Betcha this is coming from someone who "read" a magazine article on how underfill is so great.

Supplier would like to know the appropriate ball height to ensure suit to SMT and underfill process. Undefill using epoxy.

Yes, underfill process with dispensing. Customer require component must withstand certain strength.

Some of our other divisions have had to do epoxy underfill with BGA devices to obtain adequate reliability for aerospace applications. Are there any special layout considerations required to ensure that we can do underfill if we deem it necessary du

We never underfill BGA, but then again our products are not blasted into space. Certainly you need to provide enough room for the dispense head to move around the component in the pattern appropriate for the underfill you plan to use. Probably more

Hi all, I am looking for some recommendations on Underfill Equipment. Such as vendors, pumps, material, etc... We will be initially underfilling a 10mm x 10mm, 0.8mm pitch, 0.35mm ball uBGA on FR4 and going down in size and pitch from there. And
