Unfortunately, they are surface mount relays that require a deft hand with circuit boards. Other potential issues are (1) the NC contacts that are rated at 1/2 the NO contacts even though they carry the same current and (2) they decided to use vented relays that are supposed to have the vent plug removed after soldering to the board but didn't remove the plug because of potential FOD issues. They should have used the external protected cover version....
