making a small batch of Texas Avenger "TA" Drivers fully tested running Bistro or Narsil, Clicky or E-switch, SIR800

Ok, since the 30mm are gone Iā€™ll buy the remaining 38.5mm built the same as the one youā€™re already building for me including LDO but with the temp at 70c. PM me the price.

I have no additional LDOs so ordering more 30mm boards make no sense
I have made the notes how to modify the LDO for you

the other 38.5mm populated board would be 13$
as the 3 boards are already covered by you and BobbyMK and I got only infineon FETs left that are a bit cheaper than the SIR800

Ok, in that case could you build the one already ordered with an infineon and the remaining board with the sir800? In other words, the board set up for 60c with the infineon and the one set up for 70c with the sir800?

new solder paste arived and prooves to be good

first 10 30mm ones are ready
as I got only 200 AMC7135 from 500 received so far I will complete the first orders as there are enough to make boards

the 10 30mm fitted with AMCs and 10 more boards ready, but I am out of AMC7135 chips for now

doing more boards not fitting the AMCs now

human solder paste printer

more boards reflowed just missing the AMCs

Haha , awesome !

I have been doing the same thing , who needs stencils :stuck_out_tongue:

Looking real good. Thanks for all the updates.

Looking good!

Great :sunglasses:

and again 9 boards reflowed
so a lot reflow work done after almost 8 hours

a pitty that still so many AMC7135 are not delivered
also 17mm boards I ordered later are not here yet

there are now all drivers gone, but if enough people want more drivers we can start an interest list from now on for a new batch

drivers with AMC7135 bank up are completly populated, MCU upside no AMCs

Updated Excel table

Lexel; Glad to read you may do this again. Iā€™m in need of drivers to build triples for my 2 Jaxman E2L hosts. Have two 219b 4500K & several 219c 5000K LEDs from clemence that need homes. May try mixing tints.

I like ToyKeeperā€™s UI in the BLF A6 and now so much more has been developed by the amazing people on BLF. Will read up on all the options you have once another run is a go.

Thanks to all sharing their expertise on BLF, it is magic.

Sorry Iā€™m late to the party.

If you do another round, I would be interested in a couple of 17mm drivers. Please add me to ā€œthe listā€. Thanks!

Iā€™ll be interested in a few more too!! :wink:

Looking good Lexel! :beer:

Still in need of a L6 driver so sign me up.

for next batch please use this topic

I checked for paypal payments and one payment i cant find in my PM and Excel sheet

P.S.
solved

This is why I always ask anyone sending my a payment to include the following details in the notes. I have had too many cases where I just canā€™t figure out who is who and what is what with unlabeled payments.

I ask for them to list:

The item(s) being ordered
Forum name
Address

This way worst case I can contact them via PM.

good news today 200 AMC7135 got delivered

so more reflow work for this afternoon and evening

I got no reponse for days from kaizer for days

If he does not answer till wednesday a 17 and 30mm get free from reservation

so finally reflowed all those 200 AMCs and some MCU sides of 17/20/22mm

in the picture on the left side drivers that are ready to be programmed and tested,
already passed visual check, with some that needed some parts aligned right, remove solder blob shorts between pads

on the right side drivers with AMCs missing as I expect 100 from the last order I added after I got more MCUs and fets to build some extra drivers

I did learning by doing for reflowing drivers
I learned how to apply a tiny but sufficient amount of solder paste with some tricks
just see one of the first vs the last, optical far better, but electrical identical

so we got for programming
1 15mm Narsil
4 17mm Narsil
9 17mm Bistro
1 20mm Bistro
1 20mm Narsil
1 21mm Bistro
3 21mm Narsil
1 22mm Bistro
1 22mm Narsil
12 30mm 2S LDO Narsil
4 30mm 1S Narsil
3 38.5 1S Narsil

At this rate you will surpass myself in the most TA drivers built lol.

The latest drivers do look much better, you donā€™t need much paste at all. This is why the stencils are so nice, they give you the perfect amount and put it in the perfect spot every time and in a a couple of seconds too boot!

A tip for better reflowing is to reflow the top side components first and heat the pcb from the bottom with about ~350-380c air. First off this lets you use much higher air speeds without blowing components off and it also ensures the best possible connection.

The 7135 side just do like normal from the top of the components. They are much easier to deal with like this.
