Oshpark Projects

I use whatever the specs on oshpark are as the tolerances on my drivers, unless they changed recently that is. I always run the clearance test to make sure everything clears before releasing a driver. Never had an issue yet.

All my drivers are setup to be hot air reflowed, so the whole driver is heated and reflowed at once. In this case the thermal setup of the driver doesn’t effect the soldering a lot. Never tried it with an iron nor would I even try to do such a thing to be honest.

That’s good to know, thanks again.

Oshpark wrote me the solder mask should no exeed 30 mil beyond the board cutout to not make problems in the fab, TA boards are copper poured to the board outline and so far all boards I ordered over 200
the bigger ines have copper till to the edge, but the small not, not sure why

just too wide solder mask of the 46mm and 21, 22mm LDO had problems the fab removed the outer solder mask ring as they hit boards around
On one fab ground rings were not removed, but the other made problems

I’ve already read your former post (I guess in TA drivers thread) regarding this solder mask problem. Very helpful, thanks. Do I understand right: only the solder mask above the outer copper trace has been removed, and not the copper trace itself?

The copper pour on TA drivers is matched to the board outline, of course it would be possible to manually widen it over the board outline, question is if its working

for solder mask
The Gerber files contain a ring shape that was on some drivers a few mm over the board outline
in one fab that collided with boards around it so it was automatically removed on the panel, so the copper ring was there but fully covered with solder mask

I try this experiment in one fab
copper pour and solder mask expanded beyond the board outline

I like life to be predictable. So all my boards are made within OSH Park design rules. I design all my boards to be bigger diameter to make up for the copper-to-edge set-back required. Then, they are ground down to the edge of the copper pour. Some people have gotten by with designs that had copper all the way to the edge. But sometimes (maybe now it’s all the time) OSH Park will set it back themselves. In some cases, that can make the board unfit for its intended purpose.

I lost all my eagle stuff when I moved to linux

Can someone create and upload a 17mm to 20mm adapter board for the BLF 17mm driver for the new type C8 lights

Didn’t we used to have some copper adapters floating around here? I am actually in need of some of these myself. They were washers for something but can’t find them anymore.

New like the convoy c8? It works with 17mm drivers, I have a blf driver on mine without an adapter,

I found some that should work as adapters.

You can also get dedicated 17mm to 20mm driver adapter rings. I used to get mine from 3Tronics (now closed) but Googling “17mm 20mm adapter ring” produces several hits like this one from Kaidomain:

(TinyURL because the Kaidomain link broke)

There are other sizes at the bottom of the page, too.

Right…we used to have some at OSHPark that would allow fitting a 17mm driver inside a 20mm ring…or I believe we did

A fellow BLF member I talk to got a new light in and I was asking for him

The problem with oshpark is that it would have very bad thermal properties and could cause the driver to overheat depending on the driver used.

Hi Gang,

I would like to have some 17mm blanks made. One with a battery positive center larger enough to fit hanks gold spring (about 11mm), but on the back side a way that I can solder a negative contact without putting wire in the way of the rim. Can someone here assist me with that?

Hey. is there any project of the nanjg 105D driver somewhere available ??

Hello and welcome in BLF!

What do you want to make with it? What do you need?
If you want a 105D, you have to buy a 105D or 105C
Here in BLF are some similar drivers with similar Layout to the 105D which has more output channels, e.g. for some AMC7135 chips for regulated current and for a FET for unregulated maximum output.
Look at this topics for examle:

I would like to make a few flashlights for myself and my family, based just on nanjg 105D. That’s why I’m looking for a 105D tile design without FET. based on 6-8 AMC

Look e.g. here:
http://kaidomain.com/Flashlight-DIY-and-Tools/Circuit-Board-Driver-Board?sort=p.price&order=ASC&limit=100
Convoy-Shop on Aliexpress: driver - Shop Cheap driver from China driver Suppliers at Convoy flashlight Store on Aliexpress.com

They have very similar drivers. Some are an upgrade to the 105D. The 105C is the same as the 105D but with aditional stars for some options.

A good driver is e.g. this: https://www.aliexpress.com/store/product/7135x3-7135x4-7135x6-7135x8-with-new-firmware/330416_32734523412.html?spm=2114.12010612.8148356.8.5bb73cf1I0IKuV

Is this something okay under 105D?
