content: Here is my first attempt at a teardown and review. The Tenma 2062633 rework station is quite good value for money I purchased my unit about two years ago for approx. $177 AUD from Element 14. Somebody else has done a review here is the link [http://goughlui.com/2014/09/29/quick-review-tenma-smd-rework-station-bundle/]The build quality is not the best as can be seen from the photos so for hobbyist use should be ok; the build quality issues are the following;Hot air gun leaks fixed by applying high temp RTV silicon between the two halves that’s why you can see red down the sides and replaced the screws with 15mm screws the originals were too short. I don’t know if I agree with the other review which states that the unit would be unreliable over time as the transformer is only rated for 220v, I’ve seen this before and haven’t encountered failed transformers due to underrating more from underrated diodes and capacitors.Wires have been directly soldered to the mains plug and top molex connector instead of using proper connectors and terminals. Use of heat shrink is atrocious, do it properly and use correct sizes. The boots that fit at the end of the soldering iron and the 7 pin Din plug at the station end just slip off, they used microphone plugs I think these are unsuitable and would replace with high quality connectors.The other review mentioned dents on the casing of the station, misaligned iron connector and switch I didn’t have these problems with my unit. The tips supplied were ok but I swapped them for Hakko 936 tips the tips which require the small collar will fit as the ceramic element on the Tenma is slightly larger than the Hakko. Also Hakko barrels and connectors will fit on the Tenma.Some final points the micro is a PIC16F916 and all electrolytics are 105°C but they look like poor quality types so change them to Jamicons or similar quality.Performance wise it is quite good the hot air gun takes approx. 1 minute to warm up to 350°C and airflow is strong and consistent, the soldering takes about 2 minutes to warm up to 350°C and maintains constant temp.All up for the price it is quite adequate and I’m happy with it.

content: I couldn't fit all the photos in the one post so here are the rest. The iron stand by the way is quite good.Cheers

content: I'm fairly confidant this a Tenma re-badged Atten AT8502D which is a Chinese mod of a Hakko 952 or similar.If you were spending similar money today I would buy a genuine Hakko 888D and an Atten 858D or equivalent hot air station similar to EEVblog episode #167. That would be around $230 AUD delivered, or $150 USD for the US 120V versions.Myself I have the same functional setup for $60 AUD delivered, a $15 Yihua 936 and $45 Yihua 858D.
