does anyone within about an hours drive from North Bay have a nice solder - desolder station with anti static workbench I could drop by and use?

I don't have the workspace for this type of job and I need to remove and install a 28 pin chip

If you are going to trash the removed 28 pin chip, snip all legs off and then remove them one by one.

Is this a linear or logic IC? If linear, it should survive normal soldering technique. I've done it....just don't use a cordless iron.

In my electronics lab, I use the Hakko-FR-300;

Once you use a product such as the Hakko FR 300, you will never want to desolder using desoldering braid or a mechanical vacuum pump.

If you want to remove an IC to reuse, the Hakko is highly recommended.

Make sure a temperature controlled solder station is used. Try it at mid temp first and then adjust accordingly using the lowest temp that melts the solder. I like using a Sodapult solder sucker ($10-15) for desoldering. If you plan to install the chip elsewhere I recommend get a 28-pin socket for it. That way it can be pulled and reinstalled repeatedly without damage it you are careful. I also have linear chip pulling tool and an anti-static armband I use when working with chips.

ON second thought, just get someone to do it for you that has experience and the tools.


Just be grateful you aren't dealing with surface mount PCB's.

If you don't find anyone locally - and you're heading down the 400 towards Barrie at some point - I can take my kit to the cottage. But I'm 2 hours south of you near Big Chute.

Why? They're easier to desolder and remove the components. Resoldering is a little tougher than through-hole, but not by much, especially the large pieces like chips.

So you have a hot air reworking station? What about an ebb and flow table??

Desoldering easy. Soldering, NOT!

Don't need anything ‚Äčlike that; 2mm chisel point on 25 watt pencil iron, wick and/or pump for desoldering, as the case may be. Can do SMD on up with it, but 12ga speaker cable takes too long. :wink:

I don't doubt being fully kitted out makes life easier, but it isn't absolutely necessary, IME.

I do have a soldering station and solder pump that you are welcome to use.Can't help with an anti static table though.
Located on the South Shore of Nipissing near Stormy Point
