Hi, I am looking for land patterns for 0612 and 0508 chip capacitors. Because they are not standard (yet) package sizes, i am having trouble finding a standard land pattern. (If you don't know what these are, picture a 1206 or an 0805 with the te

I have a customer want to add an SMD coil to the board, which they used to hand soldering all the time. I want to know is there footprint/land pattern size that I should follow? Any recommendation?

we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,

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

thank you very much

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

hello; When we are doing component land pattern design , one thing will always be in our mind; that is the basic criteria or common land pattern design guideline for reflow and flow solder assemblies. For basic fomula in calculating resistors are:

Wendy: The IPC-SM-782 Pad Calculator (www.ipc.org/html/fsresources.htm) should be able help you solve your problem. Good luck Dave F

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-
