    It seems like I'm doing a lot of board work more recently, Swapping chips on a WPC, recapping a Sony PVM Monitor, swapping a CPU on a 70s computer (why wasn't this socketed to begin with?). All through hole stuff. After doing these sort of repairs, it's become evident that using a spring loaded solder sucker isn't for me. Now I know there have been discussions on different brands and stuff, but what's the general consensus on handheld vs station based desoldering guns?

    Essentially, is it worth it to go get a big station and shell out a bunch of money, or do the handheld guns from a reputable brand work just as well?

    Eg,
    A handheld self contained unit might be $300, and a station $600-700, but the station has the ability to operate an iron as well.

    I'm also trying to keep in mind that I'll have to pirchase different sized nozzles, which just up the price. I'll definately be using it a lot more, since it'll makes my time removing things faster.

    I prefer hand-held since I need it for playfield work, in addition to board work.

    Hakko has a nice desoldering gun. I've been using the FR-300 for a number of years, and they recently came out with an improved version FR-301.

    I think I have 3 nozzle sizes--0.8mm, 1.0mm, 1.6mm

    Also be sure to get the appropriately sized cleaning pins, a drill bit, and replacement filters.

    Yes, it's a lot of money to put into a tool, but I've found it to be an incredibly useful tool. Like you, I started with those spring loaded solder suckers, and a desoldering gun makes a huge difference, so I've never looked back.

    I've never used a station but my hakko FR301 is probably the best example of "right tool for the job" I've ever experienced in my time in the hobby. Saves so much time and mistakes if you are doing board work with any sort of regularity.

    #4 4 years ago

    Oh believe me, I'm gonna be getting one, there's no question about that. (Especially after 30min to remove a chip without cutting it out) While hakko's prices are high, their quality is even higher. I've been using one of their little stations for point to point wiring in vacuum tube stuff for the past few years, and it's amazing, really gets the solder flowing.

    How's the weight? I know it's a little heavier than the stations because of the built in pump, but I can't imagine it's that bad

    It's not. It's about a pound.

    Been using a re-badged Hakko clone, works fine. Bought from their ebay store, under $100 when there was an ebay coupon.

    Another +1 for the FR-301. This thing is such a timesaver, especially when doing ICs or anything else with multiple pins for that matter. I can't imagine the number of thru-hole barrels I would have destroyed without this thing.

    Ditto with what Biff said. I've had one for a around year with absolutely no issues. Rarely clogs - to the point I can't even remember when. Great suction.

    Even better when one sale.

    #9 4 years ago

    Well, I would have gone with the clone, had I not found a FR-301 that was on sale. I was able to get the gun, 3 tips, cleaning rods for the tips, and 10 filters for a little over $250. Free shipping, sales tax was covered as part of a promotional deal, and 5% off all Hakko products. Not too shabby, considering the stupid tips go for like $15 a pop. The only thing I wish I had was the quick changing station for tips, but that thing is like $150 in it's own right.

    #10 4 years ago

    I too bought the Hakko 301 handheld desoldering gun.

    I am overall pretty happy with it, but -

    I have been reluctant to use on IC chips on WPC CPU's. The WPC ic's are notorious for whisker-thin traces.

    I have read others who use desoldering stations that say the "chip will just fall out" after desoldering. I find the Hakko does not work this completely. I still will use some soldering wick and gentle manipulating with the ic chips i have replaced on System 11 games.

    So overall, I like it, but it is far from a perfect solution.

    Sometimes adding new solder helps suck the old solder out.

    I'm a believer of the Pace brand desoldering stations. Bought two of them when I worked for a route operator way back when.

    Bought them from Kimco (gokimco.com) when they were just starting out. They keep a good stock of service parts which is important.

    Got a link to the sale if it is still going on?

    I think the site is TEquipment

    Quoted from fiberdude120:

    Hit the nail on the head. Hak5 gets a 5% discount on all hakko equipment, and notax discounts the sales tax. Should be seeing it in about a week.

    As far as the solder situation, I just swapped one of my WPC's over to NVRAM, and it took a decent amount of unsoldering and desoldering with fresh solder to get it flowing, and that was with a wick. A little bit of liquid flux works well too. Didn't cut the chip out, and it still works. It just needs something to help get the solder flowing, otherwise it doesn't wanna come off. I see it a lot with 70s-80s computers, dunno what it is, but it's just harder to reflow and remove. I don't have that problem when doing earlier boards though. Weird.

    On WPC cpu boards, I cut the IC chips out then use the Hakko to desolder the remaining leads. Saves the very delicate traces from damage this way.

    I have been using the Aoyue 474A++ for years. I'm really happy with it's performance, and it has plenty of replacement parts that are fairly inexpensive.

    I always pull my boards out to work on them at my work station, so I don't need an all-in-one station like the Hakko FR-300.

    #18 4 years ago

    I use a pace mbt solder/desolder industrial station myself

    They certainly make life easier!

    Anyone have preferance between regular and extended tips? Advantages or disadvantages?

    Regular tips heat up faster and don't cool down as fast when doing the actual work.

    #21 4 years ago

    I have an old Hakko 472 station I bought off ebay a few years ago, and rebuilt the pump with available parts. It was pretty reliable up until about a month ago, when the thermostat began to stick on. I think I need to recalibrate the heat settings on the gun. I hope to get a few more years out of it. Right now at its lowest settings, it will leave singe marks on newer boards.

    Quoted from MrBally:

    Adding to MrBally's comments... I would suspect the longer tips have a higher tendency to clog. Just a WAG tho.

    I picked up a Hakko FR-301 a year ago on sale and finally got around to using it tonight on a Bally lamp board. This thing rocks. A few practice sucks on another lamp board's SCR's and I tried it on the good board, and they practically fell right out. One question for you pros, the 301 was great on leads that were sticking straight out the back of the board, but a few of them were bent 90' before they were soldered at Bally, and required a little massaging with the tool 2-3 times before they were freed. Is there a better way to do this, or is it just a necessary evil? Any other tips you can share? I found that tinning the tip between sucks helped a great deal.

    You can desolder a small portion of the pad...Then use a flat X-acto knife
    to lift the stem.. Or the flush cutters can do the same thing.
