NO he doesn't, at least in the USA. I have a friend who owns a
vertically integrated box- building company. If one wants to use their
full set of services, one can supply a diagram drawn on a yellow pad.
Their engineers will design the schematic, make the boards, stuff and
solder them, install the boards in the selected enclosure, test the
product and repair any problem, package the product for shipment and
turn it over to the carrier of choice for shipment.
We use them for our Roy and Annie induction heaters, starting at the
handing them the schematic file, the layout file and the Gerber files
plus the test criteria. I designed the devices and did the board
layout. They periodically and randomly ship me a unit from the end of
the assembly so I can test it myself to make sure that they're
maintaining my level of quality.
If I do a firmware revision, I email them the new board layout and and a
pdf that contains the new nameplate. I made provisions for in-circuit
programming so they handle that. They etch the new nameplate. For
finished units that have not been shipped, they unpack those units and
make the changes. All this for an extremely affordable price. All of
this is leading up to...
On our first visit, I asked about ROHS. He scowled and set us down in
his office for about an hour lecture on ROHS. He started off by calling
ROHS the spawn of the Devil and showed us some some ROHS boards hanging
on a wall that had tin whiskers at least 2" long.
He said that NASA was one of his largest customers and that they'd
reject work with PPM levels of tin in the solder. They send in an
inspector every month or so to test the bath and solder paste. So will
the military. Automakers will reject any ROHS in critical, must-work
systems such as the air bomb detonator board and the powertrain
computers, among other thing.
He told us that if we chose ROHS, the price of that part of the job will
double. That's because it requires different flux and solder
(obviously), a different flux placement nozzle head because ROHS flux is
more viscous, the ROHS alloy is more viscous than regular, requiring a
more powerful pump for sending the solder over the wave-forming wedge
and about once a month, they have to shut down and go over the wave
soldering machine with heat guns to melt away the whiskers that had
formed all over the machine. He said that they had learned that the
hard way when a whisker grew up into a sensor housing and shorted the
sensor.
Between the building is a trough containing weak detergent solution and
a scrubber-type door mat, followed by a flowing rinse bath, followed by
a drying mat. This tells me that if they have to take such
extraordinary separation and decontamination measures, ROHS is not for
the individual tinkerer.
We made the decision on the spot. Conventional solder. No EU sales.
The EU has made some of the most stupid rules dealing with electronics
and this is probably the worst.
We once sold 200 units to a guy in Germany. I am fully confident that
he attached "ROHS" and CE stickers and sold them into the EU market. I
decided that too much liability (the old "you knew or should have known"
bit) might reflect back on use so I stopped that program after the first
shipment.
I know that there will be someone pop up to say how successful they've
been at hand ROHS soldering. Good for them. I consulted several
experts, including flux and paste manufacturers. I did not have the
time to test an infinite matrix of solder and fluxes.
My partner's wanting to continue to sell wholesale to Europe was a major
ingredient in our friendly breakup. He is still operating,
manufacturing the Annie, a specialty heater that anneals the mouth of a
piece of brass before further processing the brass into ammunition.
fluxeon.com if you want to see. I'm over 65 so when this Coronavirus
hit, I retired.

With modern ROHS requirements, you will need to build it with lead-free

Michail, I have an unbuilt Heathkit 5MHz model IO-4105 scope kit, in
original box. Picked it up at a flea market a couple of years ago!

Count me in.
I’d like to group buy for a price break.
I’m thinking the garage door opener on page 23.
Sorry, no need for the extra remote for $25. No one is rich enough to
have a second car, but a nice option for those super rich.
Ok,,…ok… On a serious note.
I’ll take the scope on page 94. I hear in about 40 years, you can convert
to a clock.

Since we all seem to have time on our hands...
Let's order some Heathkits!
Time to go on the "Way Back Machine" and make your orders!
