I used an iron file that was about the exact width I needed and just slowly went back and forth about 50 times until I saw the metal and then used sandpaper the rest of the way.

It works like a champ! Here Best Regards Emmanuel. I just want to tell you that I succesfully used your DS rework How-to. If you have a multimeter test the voltage on pins 16 and 20 before and after. Without that webpage, I would never datashet thought of repairing it like that!

It won’t do it no good and may result in early death of that part due to excessive internal heating. The 0V-reading tells you that you successfully disconnected the cs1287.

Care for the polarity! These are intended for short-term use with dw1287 charge and discharge intervals – not for long-term storage with a comparatively small discharge rate. Have a look at the graphics below. Most likely you won’t get a wire soldered properly to it. Thank you very much for putting this mod on your web site. Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. I appreciate it greatly.

Dallas Semiconductor DS Module Battery Replacement

I discovered that the RTC chip was dead. Possible Results Reworked chip inside a Mod. I used a medium sized flat file The case is usually pretty much “solder-resistive” because of the anti-corrosion plating. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC. On March, 23rd, Chris xrisl [at] yahoo.

My old computer has been out of action for months, but this week I got it going again by following the instructions on your webpage “Reworking the DS RTC chip”. William Walsh did the DS-Rework to get an external datadheet to it as well. Can you imagine my amazement and relief when I discovered your web site describing the DS rework process.

Attached the two wires dds1287 the exposed pins and put the new lithium cell in the holder. Soldered and used a CR battery with holder on top of the Curiosity killed that cat.

All described modifictions apply to this chip as well. Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly. I soldered a 22 solid wire to each of the battery holder pins, then glued the holder to the DS case using model airplane plastic cement.

A really new, fresh and unused chip is hard to get. Then the battery and xtal are placed atop of the chip, connected to the pins and everything is covered with a pretty rigid protective compound.

On Datashet, 7th, Emmanuel Da Piedade emmanuel. Then circumstances kept me from working with it until now There are no provisions for one. You did a great job!

You can see the result here sorry, the text is in french: Should work like a charm. A couple weeks ago when I finally got around to hooking it up After the dust cleared Don’t use rechargeable batteries.

It sets too fast! Go with the hot glue. The only things you need to do is: Even its successor DS is pretty hard to get and darn expensive.
