Peeling traces on homemade pcb

[Otsismi]

I recently etched a pcb using a radio shack blank. When soldering components to the pcb, the solder flowed to connect the trace to the leads of the component, but the trace became unglued from the board.

What am I doing wrong?
Is there a board quality issue?
Is my iron too hot?
Is my flux eating away at the glue?

I would say it's board quality and/or undercutting.

Where the acid eats under the toner

Board quality is an seemingly obvious fix. Buy better boards!

Undercutting- don't leave the board in the acid for so long. I use the sponge method personally, on phone, can't link right now but Google: instructables etch sponge

I've never seen undercutting that bad.

My vote is iron too hot and much too long. It's a balancing act. The iron needs to be hot, the parts and copper must be CLEAN, so you can get in-and-out FAST. 2 or 3 seconds. Yet still have a GOOD joint.

Yes go with PRRs recommendation.

I am a fledgling on these things. So his insight is certainly more useful.

There is no sarcasm in the above BTW
