Check the centering force, and change it to High, if it isn't already.

Windowpane your ground planes, this will prevent a lot of voiding.

Hi there: I'm having trouble to assign an adequate vision Type to dpak components in Fuji Flexa (placed by an IP3, SMD3 vision system). Currently we're using 254 but accuracy is reduced and also can be placed backwards (yes, I know... supplier packag

Hi all, I'm having issues placing 7 pin DPak packages. I'm using mechanical centering with four centering phases (one for each orientation). Tool used is A24S. Machine picks up the part but will reject it when centering the part. I have measured all

We have had two jobs that have the same issues with DPAK's sliding off their pads during reflow. We tried to resolve this by placing epoxy on the side of the component to create a "dam". However this is not repeatable enough to be a quality resolutio

Hi All -- I'm about to design a DPAK part (case 369A-13, Issue Z)onto a PCB . The part's maximum length as given in the datasheets (On-Semi MAC4DHM) is 0.030" longer than the recommended land pattern as given in that same datasheet. (1) Has anybod

Good morning, (1) This depends on component type. In general it would be better to have fully populated board. Or at least you should mount components with different thermal mass. You should place TC�s at three points at least: component with high t

Hi Larry, you might find something looking for the thread "D-Pak misalignment Problem - Kantesh Doss 23:43:23 12/02/1999" Good luck Wolfgang

Usually the alignment problem comes from pad design. The ground pad (largest) is too small. If that is the case (and even if it isn't) try placing a dot of SMT adhesive before placement (it will cure before reflow and hold the part in place). Goo
