I am using a GQ-4X with a sotc8 clip to read a Fairchild 93c56 chip which is still attached to a pcb.
However the reads dont make any sense and are in consistent. Do I have to removed this chip from the pcb to get a correct read?? Is it possible the pcb circuit needs to be powered to read 93c56?? Reply 1 ZLM Posts. The in circuit connection always be tricky.

It is power related old issue. I think you need to remove the chip from PCB. Since you already have a testclip, then you do not need the adapter. Reply 2 NewBPro 8 Posts.

I ordered a adapter anyways for other projects. But thank you for your help. I assumed it was a power issue. I will have to remove burn and resolder.
Reply 3 NewBPro 8 Posts. Ok So I removed the 93c56 chip today ppin tried to read out using test clip however i still get a blank dump. Reply 4 NewBPro 8 Posts. Ok as it turns out the test clip I have some of the pins where thye should meet the chip are uneven preventing me from getting a read any way to fix this?? Reply 5 ZLM Posts. Most of cases the uneven contacting problem is due to the chip pin is unclean or pin pitch changed during the desoldering process.
Make sure your chip pin is clean and the pitch is even.

Use a magnify glass to check or use a new chip to confirm the testclip working good. Reply 6 NewBPro 8 Posts. It seems as the pins from the test clip are uneven since i got the clip it was that way. So Im going to try to file the pn down see if that helps.

I received my adapter came in handy. I still have to find a replacement chip at this point. Anyone know what chip replaces a F93c56?? Reply 9 NewBPro 8 Posts. Ok So I got my replacement chips atmel 93c56 chips. I will be using one of pni to replace a fairchild 93c Is there anything special I need to do to write the dump file form the fairchild 93c56 to the atmel 93c56??
