Larger contact boards are a rare item. Thankfully several members here had designed some contact boards and published them as OSHpark projects. I took the liberty to make a line of boards to my latest needs and I’m quite happy with the result.
Looks pretty sweet to me. I’m looking at the picture with the Nanjg boards: is there any issue with components touching the large exposed copper area on top of the adapter? Are you just using kapton tape or is that not a problem?
The contact board sits on the 4 AMC7135, which are the highest parts of the Nanjg 105c on the spring side. But admittedly the difference in height is small. If you solder the board askew, you might touch the stock capacitor. You really wouldn’t want to do that
When you click on ‘order’ for the 22mm boards it shows:
“Your design will cost $3.75 per set of three.”
That includes shipping. So it’s 1.25 apiece. That’s way more than the 20mm boards from Fasttech, but it’s still reasonable, at least for me.
I saw that after registering. It’s very reasonable for a custom printed contact board, but I don’t like how one can’t create a composite order [no ‘add to cart’ button]. Also, what’s their average turnaround time for making an order?
these Eagle/OSHpark combination is a hoot - and is getting addictive.
It’s fun to see how many already contibuted to the OSHpark projects thread, if only by making boards for their needs, and in that way helping and inspiring others.
I made these boards some time ago. It took a while for them to get made, being sent to Europe, surviving customs and getting in use by me.
I was quite busy in the meantime, learned a lot. H)
Had good help.
My mistake! I should have known that without looking - I’ve relied on the height of those 7135’s myself. When I looked at the picture I saw something shiny touching the contact board. The shiny thing I saw was the copper you used to sew the two PCBs together through the vias (nice!).
FYI if you order several things in a row they almost always ship to you together. They have a system which combines orders for shipping as long as the orders are produced on the same panel. Generally only about 1 panel of boards is produced per day. It’s not the same as having a cart, but it’s something.
Just ordered some of these, my 1st order on OSH Park!
Got about 10 Ultrafire F13’s with this size board that the Late Great Old Lumens did a Special Price on with one of the Chinese suppliers.
Been meaning to get around to Modding the awful driver (has High, Not So High and Medium Modes with good HIGH PWM, plus blinkies) before gifting, but only managed one 17mm Nanjg swap in so far due to the odd 22mm size.
thx, it’s nice to see these boards can be of use.
When your boards arrive, I’d be interested to know:
Does the center hole (a via) still come plated?
Which Nanjg do you use and does it’s spring still fit through the hole?
