DIP spacing for designing questions

Layout Footprints
1

Hello and thanks in advance for your time,im brand new to pcb designing and i am wondering if someone can tell me what dimensions i should put when copying the standard spacing and dimensions of a breadboard so many of my electronic items are DIP style and i figure that instead of busting out the calipers everytime or having to google the data sheet i can just use the standard hole size and spacing difference for the vertical access then i will only have to measure the horizontal access once i plug the numbers in, so in essence thats what i am asking if someone can give me the standard dimensions to breadboard spacing and size for the vertical access,thanks in advance and please feel free to poke holes in my logic if i am wrong :slight_smile:

Rather than poking holes in your logic, iā€˜d poke dots in your sentenceā€¦

Id like to poke a hole in you :slight_smile:

DIP ICs (if I remember correctly) are all on 0.1 inch centers. But if you will be designing a pcb I strongly recommend that you choose SMT devices where those are available. When all is said and done the through hole ICs have little or no advantage compared to SMT. FYI my hands have always been unsteady and I am doing a lot of hand soldering of SMT parts.

Comments about referring to the datasheet are ā€œspot on.ā€ Go to a distributor website (Mouser or Digikey for example) and search the part number and pull up the datasheet. Use of calipers makes no sense (and will be less accurate) when the correct information is available and published.

I have been doing this stuff for > 45 yearsā€¦

What are the benefits of smd over tht?

  1. Because there is much more of it used, I think the price is generally lower.

  2. It is much easier to rework. Removing an IC is never fun but removing a through hole IC is much more difficult than removing many SMT ICs.

  3. The 0.1" pin pitch of through hole sounds like it would be easier to work with than the 0.05" pitch of a larger SMT chip such as SOIC. But the through hole has the holesā€¦and I think that the space between the pads is likely to be less. So I think I get solder bridges more often with hand soldering DIP than with SOIC. Now there are many other SMT packages with much smaller pin pitch and that gets more difficult as you get smaller. But I donā€™t think there are many situations where your only choice is between DIP and TSSOP (for exampleā€¦that is a finer pitch SMT package.)

  4. Of course, a smaller IC permits smaller boards (up to a point.) You pay for board size.

Here is my own personal trick: Fat corner pads. It does make hand soldering of SMT ICs easier.

Hi @Do_not_sleep

DIP packages are .1 inches between pins and usually .3 inches or .6 inches between the rows of pins.

If you go into the Kicad PCB Footprint library and scroll down 'till you reach ā€œPackage_DIPā€ you will find all the footprints.

You will even find holes poked in the pads. :grinning:

The OP asked a serious question

The supplied DIP footprints will contain the correct pin spacing and hole size

If you are emulating breadboard then 2.54 mm( 0.1ā€) spacing and 1mm pad holes. But some specific tru-hole components may have different requirements ( and donā€™t fit in breadboards either )

Always verify the footprint of each type of component before use. This is typically against a datasheet or last resort a callipers.
