TCS DP2X-UK Decoder Installation for HO-Scale Hornby 2-6-4 Stanier 4MT Class 4P locomotive . It was performed by the TCS customer.
Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157 http://www.techni-tool.com
When installing the DP2X-UK in this locomotive the four wires
around the NMRA socket must be moved to the front and back side of the decoder
to prevent them from blocking the shell from sliding down either side of the
frame. As demonstrated below we ran two wires around the back side, and two
around the front and the decoder fit wonderfully.
Other solder tips:
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
