SMPS transformer needs eyelets in PCB?

[grizedale]

Do you know if the holes in the PCB for the SMPS transformer will need eyelets in them?

The PCB is single sided, and the transformer may possibly break the copper on the bottom side if the pcb holes for it are not eyeletted.

Also, how heavy does a component have to be before eyeltting becomes necessary?

You need not solder the flying leads of the Tx at point of entry on the Single sided PCB.Take the lead thru an adjascent hole and solder on the lower side directly on a large track island.
