If you could check the figment of the pins that would great. If they require a larger diameter hole, could you possibly revise/update your design to support these pins on your next run of boards?? Thanks for looking into it, it’s much appreciated
I'm currently looking at the re-order and what can be changed in the design.
The Mil-Max pins require a 0.91mm mounting hole. That is definitely doable without major impact on others.
The single-row pins suggested by caius and ShootTheCore are most likely going to require a larger hole, if they are similar to the turned-pin sockets I've got on my desk they'll need a bit holes a bit larger than 1.3mm, assuming you want to bury them similar to the Mil-Max pins. (If anyone has used them like this, can someone confirm the required diameter?) I'm a bit worried that this will make the boards less usable for everyone else who wants to use normal sockets or solder the chips directly.
The options are:
- leave boards as they are. If you want to test ROMs before installing them, order a forth set for tests and use normal sockets.
- leave boards as they are, but drill out the holes to the required diameter. Not sure how well that would work, that may be quite time consuming, and you may need to solder the pins from both sides to get good contact.
- change the holes to 0.91mm for the Mil-Max pins. I have not tried the pins, and I'm not sure how much of the diameter is lost from hole plating, so it may be a good idea to go to 0.95mm or something. I don't mind doing this if nobody has objections?
- change the holes to something like 1.3mm (If someone can confirm the required diameter.) I don't mind doing the design change, but I'm reluctant to order all boards with this design.
What are everyone's thoughts on this?
