I recently purchased a very nice condition used JBC JT6040 professional hot air station and accessories kit. The unit was originally purchased sometime around 2007 to fulfill the SONY service centre equipment requirements of an Audio Video repair centre. Apparently SONY provide a list of equipment that service agents must have in order to be accredited. The JBC hot air station was such a requirement so clearly SONY liked it !
The owner of the unit advised that it had only been used about 8 times as the tech mainly carried out out work not requiring a hot air station. The Audio Video Centre closed and the JT6040 just went into storage and has been there ever since. The veritable 'Barn Find' of JBC hot Air Stations
I was fortunate to win this system at a very reasonable price and when it arrived it was better than expected. Not only was it in excellent condition, it also included some accessories that were not even shown in the auction
So what was in the box ?
This was the 'Deluxe' kit so it included parts that are normally optional extras. the parts list is as follows:
1. JT 6040 230V/800W Hot Air Station
2. JT6040 230V 700W Hot Air Wand
3. Foot pedal for foot operated hot air
4. 3 sizes of hot air nozzle, two of which are angled types
5. A complete set of PCB protector shields, Tripod IC lifters and combined Protector/IC Auto lifters
6. Storage unit for PCB protectors and Auto lifters with accessory draw
7. Spare filters for the Vacuum intake port
8. JBC approved sticky flux in brush type bottle
9. Instruction manual.
So there you have it, the complete kit
This would have cost a small fortune in 2007 when it was on sale and would not have been an easy purchase for a service agent to make when wanting to become a Sony Service Centre, especially if not needed for most work taken on at the time. With only 8 uses, I doubt the unit came anywhere close to paying for itself.
For anyone wondering what the PCB protectors and auto IC lifetrs might be.......

https://youtu.be/s0cKS2fq43MIt is a great system and the lifters are somewhat rare on the secondary market, except when sold with JBC systems. The clever design helps to avoid collateral damage and the need to hold onto an IC with tweezers whilst awaiting desoldering temperature to be achieved. NO more accidentally lifted traces either. Why no one else has not made clones of the system I do not know. It is very expensive to buy from JBC.
So I had this veritable JBC time capsule in its original box but would it still work ? Hmmmm read on to find out
The system was assembled and tested..... it all appeared to be working fine and I could see from the lack of oxidisation and discolouring on the wand/nozzles that it had indeed seen very little use. the unit was working well but I had concerns about noises that the main blower turbine was making. It did not have the expected 'clean' howl of a turbine as there was a distinct nocking sound and unidentifiable noises emanating from the pump. I suspected dry Oilite bearings as the unit had been unused for a long time. I was going to investigate the internals of the unit anyway so I was not concerned about the blower turbine needing a service. I also wanted to check the rubber bellows of the vacuum pump to see whether they had perished.
The top cover was removed easily for access to the internal parts. At this point I would like to say that I was disappointed to see an 'all plastic' casing on such an expensive professional product. I am used to the metal cases of PACE and Weller stations. Once the cover was removed it was easy to identify all sections of the design. The control and display boards were in the front section of the casing whilst the main casing plastic chassis contained the power control board, bellows type vacuum pump and Blower turbine unit. The front and rear panels are easily removed to provide access to the various sections of the unit. Not a bad design but I saw relatively poor cable management within the main unit and there were cables that carry mains voltage in contact with the top of the Blower unit that will inevitable vibrate against them. Hmmmm not that impressed on the cable management front
To remove the Blower turbine unit I had to remove the rear panel and move it out of the way. This allowed me to unscrew the two blower unit mounts from the chassis and slide the blower backwards to disconnect its output pipe from a silicone coupling that forms part of the front panel Wand connector. The JT6040 uses an easy disconnect wand system that allows replacement of the wand and hose in seconds. The wand connector incorporates a 6 pin electrical connector as well as the air path and air seals etc. A very nice and convenient design
. The Blower unit has a 'nose' attached to it that interfaces the various cables with the air path of the blower. This 'nose' is held in place with 4 screws and is easily removed to enable removal of the whole blower unit from the station. A two wire motor connection between the Blower and the main power control PCB also needs to be unplugged.
Once removed from the station, the Blower Turbine unit was dismantled, inspected and repaired. The full story of that repair may be found in another thread on this forum.... here......
https://www.eevblog.com/forum/repair/jbc-jt6040-hot-air-regenerative-pump-repair-help-needed-to-pull-the-rotor/I am pleased to report that the issue with the Blower Turbine unit has now been resolved and the JT6040 is back in perfect working order. At this point it may be worth me stating the systems specifications:
Station power consumption : 750W
Hot Air Wand Heater Power Consumption : 700W
Wand output temperature range : Officially 150C to 450C but mine goes up to 460C
Wand Air Flow range : 6 to 34 L/Minute*
*The output air flow may not sound very impressive compared to say a Quick 861DW with its claimed 120L/Minute capability but as Rolls Royce traditionally said about their vehicles BHP figures ..... "Enough" applies here
Whilst very high air flow might sound useful, do you really want to be blowing components off the PCB ? In my experience briefly using the JT6040, it does not need anything like its full 34L/Minute capability to get the job done efficiently and without collateral damage.
Well I think it time to start uploading pictures now, so here we go.........
