neo pixel stick copper pads broke

Post by tanery »

hi there
i was wandering if this might be due to a defective part or the copper pads are not that strong?
my neo pixel stick copper pads broke off the stick after i soldered pins to them is are there other points that can be used instead of the copper pads.
Could mine just have been a defective pcb?

thanks

The pads are just copper on a substrate so they are not very strong. If you could post some photos perhaps we can give you some advice.

As Franklin says, the pad are just a copper layer on the pcb. They are not as structurally strong as a through-hole connection. Significant torque on a pin can cause the pad to detach from the surface - especially if the adhesive bond has been weakened due to an overheated solder joint.

You can strengthen them somewhat after soldering if you clean the joints and apply epoxy over them.
