Very nice compact board! :beer:

WHAAAAAA?? For reals???

So how much for this unit?

Just out of curiousity, how come you don't make boards using surface mount technology? IT's easier to make larger quantities if you do, plus they can get smaller too.

I also think cost is lower too. o:

I'm using through hole in my 5$ Open Source regulated Ophir power supply so it's easier for people to make themselves, as most don't know how to solder SMD.
I don't know why Jerry hasn't moved onto SMD since these are not for DIY; is it loads cheaper and he can do it on a smaller PCB too which saves money, then he can pass the savings onto the customer or make more money for himself.

How much are you going to ask for this Jerry? :beer:

Ophir.......I like!!!! Man i got to say, i love all the new LPM designs popping up lately, doesnt matter if it is LaserBee, ARGMeter, or just members making their own DIY kits. LPMs are starting to get cheaper and more available to the laser enthusiasts!!!

right on, the more LPM's out there the better for the consumer's. more options, better innovation, and lower prices. WIN WIN!

Without competition there is no need for innovation and progression. Innovation and progression makes for better competition. Vicious cycle

I doubt Jerry's company, or anyone for that matter, will be selling enough of these boards to justify having the boards pick-and-placed and reflowed by machines or fabricated through some professional service. Some of those parts, such as the screw terminals, must be soldered in by hand anyway; so you don't save much in labor either. Even if placed by hand, any savings in SMD parts would be quickly undermined by the overheads and losses associated such a small run of boards.

BB hit it right on the head...:beer:

The costs of having a professional PCB assemble company that
uses proper equipment to pick and place and properly reflow
solder any SMD parts will be much higher than the pennies we
would save buying SMD parts. I know because we have other
PCBs that have SMD parts that are done by outside assemblers.

The second part of this through hole reasoning is that we don't
want to reflow SMD parts using non properly controlled heating
and cooling curves that will stress the electronic parts as I've
seen used by some of the PCB project suppliers on the Forum.

A frying pan or Paint stripper hot air gun just doesn't seem to
be the best way to assure uniform assembly and unstressed
electronic components...

Even a Toaster Oven that does not have a PID controller in
conjunction with some type of Computer/MCU control over the
proper Heating/Cooling curve is not acceptable to me as a
means of producing high quality PCBs.

The through hole design also makes it much easier for a user
to replace any parts if it becomes necessary.

As to the price... that will be posted when they become available.
These specific PCBs will allow you to read up to 6Wattts with a
heatsinked OPHIR head and a Common Ground 4-1/2 digit DPM.

We will be sending some PCBs to a third party for in field testing.
I will report back with specs..prices and availability after the tests..

Looks like the main IC had its label sanded off

Yeah... we're not Open Source....
It helps protect our IP...
The IC still works like it was intended by the
manufacturer...

Cmon Jerry, I can at least understand that line with your meters that actually contain code, but this is just a voltage supply board.

It's a rail splitting chip and a 5v regulator for the display.

True its not open source, but open source is probably going to be about 75% less. But with no price set for these are just speculations.

Fair enough Jerry, through holes works for your set up.
For SMD though you can pick up a quality SMD rework gun on the cheap these days. I apply paste with a stencil and use the rework wand to heat up the solder to the rating specified by the solder manufacturer. You should try it, you may like it! :beer: SMD soldering is an acquired skill, but a good one to have.
If you don't have any equipment to solder SMD devices how do you solder your SOT-23-6 ADC's?

Edit:
Also, what is the point of having through hole for the user to replace components if you've removed the name of the components from the IC'S?
