What's your latest aquisition?

Here's my latest purchase, a Tri-ang-Hornby R.754 M7 in BR Black livery.

The box was tatty, crew were missing and the BR totem transfers on the tank sides were part missing as per normal.

The model is slowly being restored, a fresh box mint was found on ebay with incorrect labels (the one on the right) and I have crew and original totem transfers a plenty in stock, I will post stages of the restoration at intervals for all my friends on here to see as they take place.

Here's the loco pre-restoration but with nice new original 40+ BR Totem transfers put on the side tanks, a packet of the original transfers is posed by the loco for reference.

Hope all at Hornby like what I am doing to their old locos.

Enjoy!

@Jeff Mennell

What is it ?

.

It's a temperature controlled hot air reflow station. These are specialist soldering tools for printed circuit boards. Instead of a traditional soldering iron to solder multi-pin components, IC's for example, you place a special type of soldering paste on the PCB connection tabs, rest a SMD (Surface Mounted Device) onto the pasted connection points. Then the hot air from the station melts the paste and solders all the pins in one go. It's other use is to allow multi-pin components to have all their pins de-soldered at the same time to aid easy and efficient removal from the PCB they are soldered to.

.

It is based upon the technology used in factories that make electronic component boards. If you look at any modern circuit board, you will find that 97% of the components on it are SMD ones. A robotic machine places a squirt of paste on the PCB connection points, then picks and places all the individual SMD components in their places. The solder paste acts temporarily like a glue to hold the SMD components in place and stops them moving. The board then goes through a temperature controlled air chamber where the paste is activated by the heated air to melt and solder the components in place en-mass.

.

They also make excellent hot air guns for shrinking 'heat shrink tubing' too.

.

I haven't got one in my electronics soldering kit tool box, but I am familiar with what they are.

.

PS - I have been looking at this bit of kit (it's on my desirable wish-list). It is as close as one can get to the factory manufacturing process at home. However at 2,000 euros I would have to have a Premium Bond win before I would actually buy one. The demonstration video on the home page does however give an example in principle of the application of the paste and the robotic placing of components (later section of the video from time-stamp 6 minutes onwards).
