I’ve seen Old Lumens similar solution here: Soldering wires to a star, a little differently? - Video, and Cereal_killer mentioned using battery contact tabs. I can do these things, and I’ll try drilling too, but ultimately I’d be much more happy if I didn’t have to. Just a plan wire through a through hole, just like those cutter MCPCBs but for single LED MCPCBs would be perfect. It would make everything so much easier, I don’t see any good reason as to why MCPCB manufacturers haven’t made them.
I suppose manual soldering is not something big manufactures are thinking about, so technilogies are moving to the other side. Small connectors, point welded nickel strips, tiny laser-welded pins etc.
Not sure through hole is best solutuon, most would like rather big hole (like 2mm), if hole in shelf or pill is 2.5mm it leaves just 0.25mm to sides. If you are assembling light with wires as short as possible and fixing driver first and that soldering pcb, there is no ways to look and check if there is no solder leaked through the wire hole.
P.S.
I suddenly invented perfect decision which can fix two problems - pcb rotation and solder point under reflector bootom.
PCB with two extra half-circles protruded outside. With solder pads on them (outside reflector bottom).
Cons: you will need dremel and mill two cuts.
Should be easy enough to check for shorts, just put one DMM probe on the pill/head and check for shorts by probing each LED wire solder blob.
Yeah, that’s the downside. I’m interested in a solutions that require less work. Your design is for custom MCPCBs anyway, if your going to go custom I’m still convinced that two through holes in place of two of those wire notches would be an easier solution. If people can successfully drill their own holes and solder without shorts, soldering with pre-existing holes should not be an issue. But yeah, I have to put my money where my mouth is and try drilling first.
Through isolated hole in metall core pcb is another technology.
It took many years to move from fr4 to metall core.
And several more years from metall core to DTP.
How long will take next step? Nobody knows…
Any X6 copper or aluminum heat sinks available?
For a triple? Those are listed inthe first poet of the topic
I didn’t realize it. I PM’d him.
Is there any chance of you making an S2+ triple copper pill? The other guy still hasn’t made them yet.
There is a chance but I dont want to name any date right now.
No more custom threaded parts, dies are on sale.
Do the single led P60s have a retaining ring for the driver?
No. They have tight place for 17mm driver press fit.
Thanks for the quick response. I’ll take 2, just let me know where and how to send payment.
Where can i see it (P60 single led???) Not available in first post.
It is similar to stock one, but made from copper. Fits standart reflector.
And seems to be sold out.
Don’t have one ://
Please attach a photo on next batch.
Hi Kiriba,
Any chance of getting a couple of single led S2+ pills.
Plus, put my name down for the p60 pill if/when they become available again.
Thanks.
Single led S2+ pills are in stock.
S2+ triple spacers and pills, P60 quad drop-ins will be restocked in January.
Great,
I will take 2 x s2+ pills, please send payment details.
Many thanks Kiriba.
