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

I would go with wire thickness + 0.4 to 0.8 mm for pad width, and pre-tinned lenght + 0.5mm what seems to me like problem is that it can easily roll off the pads in reflow oven

Hi, check the Land pattern 0201 on the board, compare with another 0201. Could be different gap.,

Thank you all for your quick reply ! the problem is solved without making any intervention on line .. 0% defect rate for the moment .. for all of you who said "try rotating the board 180 °", we can't do that because the panel contains 2 boards head t

Our land patterns are slightly bigger than the part, we've had no problems. There are your own concerns about the part hanging over the pads, this can be ok or not depending on your application and/or how much part is over. I'm sure this is in the J-

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

Hi Dave, Thanks for the suggestions. To clarify a couple of the points... - What do you qualify as "small" & "large" parts? - Do not make the pad narrower than the lead width. The nominal or the maximum? If I use the maximum width I'll be back to s

"small" versus "LARGE" parts? Jeez, what do I know? We don�t have a formal definition. They�re the ones that make you say: �Now, that�s a BIG-ass part!!!� �nominal� versus �maximum�? Yes, yer correct.
