New VirEnce MCPCB for E17/E21/119/144/233U

Looking forward to those quad boards. Plan to use 4 of them with a quad optic, 16 total emitters, then put a large diffuser over the front to make a high CRI lantern. Host is a JKK36 from Kaidomain.

Will be a nice emergency lantern since it uses 3x18650 for good runtime, and has a built in power bank function in the cell holder. So I can charge my devices with it at night, and charge the lantern with a solar panel during the day.

Update: 171016:

- 60 pcs prototypes shipped!

Not any more…

Meaning?

The pic can’t be seen

Ah sorry about that. I changed the privacy policy of my albums…. accidentally in batch. Fixed many but I posted like hundreds of pictures, missed this one too. That was stupid, changed the policy back to it’s original state didn’t fix it. I have to do it manually one by one.
As for the picture, it’s not relevant anymore since the final designs are those in the OP. I’m still making my own test rig so don’t have to always overload Djozz with my test requests.

Yes, I would like to see final product. I enjoy nice pics so when someone says “Eye candy” but the pic is not available that is kinda let down :wink:

Shipment released from the custom! :laughing:

  1. Prototypes received, OP updated with the preview

They look Great! Sorry to hear they are super expensive. Once they are up on the store I’ll be picking up a few regardless as I have some projects that could benefit.

16mm single 144

There is no space to place the insulating gasket?

With such flexible options in 16mm you don’t have much room left. You better use kapton, electrical tape, or epoxy to make needed insulation.

They look very attractive! I will surely be in for some, no matter what price they will be, more of course when they are affordable :slight_smile:

Just when we though they couldn’t be more pricey, then the custom added some 40% more to the bill…… :expressionless:
I’m still trying to simulate your Djozz test here. The only datum to your test is the S3030 VirEnce board, 144AM sm653 R70, and the TASI meter test. Will report the test ASAP.

Amazing #1 test result! Check the OP

They’re so pretty. Can’t wait to order some!

Final touch by Texas_Ace :wink:

Awesome results, really excited to finally have a good option for 144A and E21A!

Great results!
These boards are also nice for an Oslon version, because the thermal pad of Oslon Black’s (that is connected to led-minus) can then be electrically insulated from the body of the flashlight.

Created many centering/positioning jigs, spent two VR16SP4 boards, some E21As (fortunately the R70), and one full day without success. Only later, I remember I didn’t stir the thermal paste after left in the fridge for weeks. Now the reflow works flawlessly. No gimmicks, just simple drops of solder paste and light tapping using flexible bamboo stick……and voila! The said to be difficult to solder E21A moved themselves to the correct position. The ultra thin solder mask do works. Perfect quadtrix board!

Many manufacturers gave up on E21A because it has very little to no self aligning behaviour during reflow. Thus requires very accurate PNP and solder dosing machine. But with very thin solder mask the self align effect restored back, even at very little solder paste applied. Thinner solder bond line, easier manufacturing, at the expense of fragile solder mask.

I use Sn96,5Ag3Cu05 (max. 260C @30seconds), with Sn63Pb37 reflow should be far easier.

I still have few hours before my flight, will post later.
