Hello, I am wondering if anybody has process experiance of designs which use the above. I understand that the filled via is an excellent thermal cnductor, which is great from a design point of view, but how do these solder through the reflow ovens

I have used the rectangle shapes and round shapes with no noticible difference. The idea is to design the pads to accept the same solder volume per component. Components over two size pads will favor the higher solder volume side during reflow.

Is anyone currently reflowing a board with SC44 devices on it. This is a 6pin SAW filter with castellated terminations. I'm looking for a solder paste design for this part. I currently use a laser cut 6mil thick stencil.

Greetings: I would like to know the common land patterns and aperture shapes that are currently in use. We are doing some research on the same. Please respond to the thread if you have a success story with you current design. Thanks KT

Most likely this can be done if the board does not have any inner layer artwork. Are there schematics available? if so a design shop can basically re-design the board from these.

Dang Patrick, I'm going to have to agree with you again. The design needs to be corrected. This multiple footprint is a common thing nowadays but the designers need to understand the dynamics of reflow and such. PWH - Why would this mask need to

Send your gerber data to the above mentioned or any other pallet Mfgr. If the assembly is designed with pallets in mind I am sure that one can be designed for your application.

Stencil thickness is related to PCB design and is not related to paste type. If you release with a 8 mil stencil then use an 8 mil stencil. Of course there are pastes that release bteer than other and what not but use area and aspect ratios to dete

We have had this experience in China. Some of our customer produce aluminium radiator. They always ask us to design this type reflow oven for it.Because the large desire of the heat,we have to design the oven at a higher temperature.It's almost meet
