Question: How would this unit fair with fixing small logic boards found in smartphones and tablets.
Document: I was impressed with the contents of the kit. I did not expect it to come with so many extras. The kit contained extra tips, a desk lamp with a magnifying lens. Tools and spare heater elements. There was only one small problem. The top cover had a corner bend during shipping. It was no problem fixing it, took about 5 mins. Good value for money. I found the station easy to use. It worked nicely.
I am with a research group at Cornell University. We needed an hot air gun and a fine tip soldering iron to work with some small pitch QFPs that electronics nowadays seem to always be packaged in as well as to scavenge the parts from old boards we no longer use. We bought the X-TRONIC 4000 soldering iron and hot air gun units as seperate units independently from the seller after carefully considering the Aoyue 968. The spare heating elements put this unit over the top.
I don't know if this unit would be super for professional work or not, it's my first, but I do tend to solder alot on my projects and pull parts from old boards and thus far it's been nothing short of awesome.
When I decided to start working on game consoles and computer boards, I was at a loss as to how and where to start. ( Being out of Electronics repair for several years )I looked all over the net and found nothing but high priced stations and most were in another country. I found X-Tronics web site and read all the information and descriptions of each product they offered. So I decided to give them a call.
I resoldered a bunch of the joints using this very station and the light started working again haha. Basically they give you a practice project to get used to the station.Been using the station at work for pc repairs, fixing DC Jacks, replacing USB ports, fixing game consoles by replacing cd motors and etc, it all works great. The only thing that I would point out is that the temperature display isn't very accurate.
I have had the Model 4040 Digital Hot Air Rework station for almost a year and a half. I love the way this equipment performs. I have repaired several SMD boards that would have otherwise been discarded. Great tool for a great price. I have had nothing but positive experience in dealing with the customer service at X-Tronic with a prompt response in sending supplies as needed. You just can't go wrong with this piece of equipment. If you are doing SMD work then this should be in your collection.
I bought this being a beginner and have found this station as a great tool in working with motherboards and replacing power jacks. I plan to keep using it for years as a way to make money during college. over all great tool. I would recommend it as a begineer .
The screws that hold the various size air nozzles look like zinc plated steel and quickly oxidized. I replaced them with stainless steel with thumb nuts fearing they would may become stuck making it difficult to change nozzles.The soldering iron and tips look ok. For those not familiar with soldering irons for small devices like SMT or fine pitch thru-hole the better the iron the closer the tip is to the heating element. A cheap iron will have a metal heating element with a long metal tip screwed or clamped into it.
I tried to use a hot plate to preheat the boards, It worked ... but I wanted something that was a little less of a problem to assure a stable temp. SO once again I called X-Tronics and asked them what they could do to help me. The Tech suggested I purchase their new 5020 preheating station. It is a stand alone unit with a handy air wand holder for precise positioning over the chip being worked on. The 5020 has worked remarkably well.
We are a commercial enterprise and as such look for both value and dependability in equipment that we purchase. We were especially attracted to not only the accessories that were included for the price but also the included spare parts and the ISO 9001-2000 " Certified Manufacturer" statement. We found the unit to be substantial and dependable, it also provided us with the ample controls and indicators that make utilizing this device extremely convenient and productive.
