Problems with Boss DS-1 Modification Subject description: Lifted pads and possibly damaged IC chip |
|
|
My apologies if this is in the wrong place, seems like the people on this section would know what to do in this situation. I am brand new to circuit bending and electronics work in general, really starting to realize how much of an art it is to do things right.
The first project I decided to tackle before messing with the board on a Roland TR-505 drum machine I have (I will need to be much better with my soldering) is the Keeley Mod for the Boss DS-1. Well documented so it seems like a good start. ANYWAYS...
I started desoldering (Using a chisel tip, 40 watt iron and a desoldering pump) and was running into constant problems using the pump. I'll be getting a wick soon, but in the process, a few pads have lifted, exposing copper (but it doesn't look like it exposed the board itself). Is there an easy way of fixing this? I've heard scraping away the guard on a little bit of the tracing and soldering to that is a standard fix.
Also, one thing I have heard is to always be careful around the IC chip. I haven't touched it with my iron, just removed a few caps and resistors nearby. I kept touching the IC chip to see if it was getting warm, and at a point it was (but not hot, just a light warmth). How do you guys know if something like that is fried until you are totally done with your modifications?
Thanks

i repair tracks with the lead cut off of a resistor........shape it with needle nose pliers......scrape away the masking on the pcb and solder it in place
if im worried about an ic i lay the board on a damp sponge
make sure everything is clean so you can get in and out
let the ic cool down....solder a couple of pins at a time |

I've modded a bunch of DS-1's, it's got some amazing sounds buried in it!
Anyways, if I mess up a solder point, just take a small piece of insulated wire, and follow the trace up to the next point. |
