I producing my pcb with process using laser printer, but i don’t know how translate description of technology in to English, sorry.
RX5,
SMD components at us are easily accessible in locally shops trading radio components.
ah ic.. thats WHERE you get your parts... uhhmmm maybe just a limited value eh??
Even I , have a hard time getting 1/8 watt resistors...
classd_fromru said:djQUAN, thanks
Am coat the copper with a thin layer of fusible alloy (Rose T=93-96°Ñ) in boiling water. I very like this technology
RX5,
In Moscow there are no problems with SMD components.
could you -LINK- me to that type of PCB technology? Im very curious as to HOW its done...
UcD v 2.5
Hi All!
I build new pre-final UcD version of my UcD
PCB, Circuit and other photos and oscillograms here:

PS
Please dont ask me Gerber files, i dont have it. You can export LAY to Gerber with Sprint Layout 4

An externally hosted image should be here but it was not working when we last tested it.

Hi classd_fromru
Nice work! -- I notice you have not fitted any over voltage protection (OVP) -- do you not have any problems with busspumping if the output is short cicuit?
On my UcD (through hole, not SMD ) the -ve rail climbs 'lower' very quickly with a short circuit output, and usually destroys the low side FET!
Even with OVP fitted, it is not always protected --do you not have any problems with this?

o.0 Wow this is great stuff, tinning.
Read this, and be amazed, how easy it is. Would be nice to with it. It's so simple. Can't wait to get this opportunity.
