Earliest example of PbF ?

[N_Cook]

Previous earliest I've personally come across was a Yamaha RS7000
sequencer, 2001 ,
too early to mention the likes of RoHS or PbF etc anywhere on that.

This time a Roland DB500 from 1999, the solder joints hazing over if you
admix with leaded solder. Or is it some other solder formulation that
can give a PbF+SnPb solder sudden-cooling + hazing appearance?

I know it all started coming in , in Japan firstly.Japan passed the
Electric Appliance Recycling Law, April 2001.
And the soldering on every aspect of Sony's DCR-TRV 30 digital camcorder,
released in March 2001, is "99.7% lead-free, including all supplied
accessories".

Anyone know what the Tick N225 compliance mark means, again on the back
of an amp with dodgey solder.
Latest component datecode 9940 and a pcb "7 segment" overlay date of 9945

I assume the circuit boards were populated+soldered in Japan, although
only reference to designed by Roland Corp USA on the rear of the Amp

"Nutcase Kook"

Anyone know what the Tick N225 compliance mark means,

** A mark like that is what many items I see have on them. The Tick ( for EM
compliance) and a number starting with "N" refers to an importer in
Australia, in NSW.

So, in this case "Roland Australia" in Sydney.

Looks like Roland print that number on everything.
