I just received TSOP adapter ADP-077, and I have a question: How exactly does the chip seat in the adapter? Are the legs supposed to just balance and sit on the pins? I've tried for a while and the legs just want to slide between the pins. How do I make sure good contact is made when any downward force just pushes the chip off the pins?

Thanks.

ADP-077 is designed for accepting TSOP32, TSOP40 and TSOP48 chips.

There is a guide drawing on the left side of adapter.

All chip ship top aligned and with pin 1 at the top left.

In order to work with different chips, different base board adater is needed.

Like ADP-082, ADP-072 etc...

See ADP-033A set for combination:

That doesn't answer my question about how the chip's legs are supposed to make contact with the adapter.

"Are the legs supposed to just balance and sit on the pins? I've tried for a while and the legs just want to slide between the pins. How do I make sure good contact is made when any downward force just pushes the chip off the pins?"

I don't want to screw something up because I had the legs sitting on the connectors instead of in-between, or vice versa.

BTW I am trying to program AM29F032B*TSOP40 on GQ-4X with ADP-077 and 082.

push the chip to the side while releasing the pressure.
Also make sure the legs are free of solder - use braid to clean them up.
