[HW CR07] AC part / Isolation Slot considerations #7

Open lbalucos opened 2 years ago

From Customer: Some modifications to this part of the PCB will be required to increase the mechanical strength.

In current versions it occasionally happens that the welds of the Murata DC / DC break / crack.

We have noticed that as a result of external stresses, the two parts of the PCB, separated by the too long slot, undergo deformations at that point that cause the weld to break.

A solution could be to distance the Murata from the Relay in order to have more space in between and space for a slot with a different layout and possibly shorter under the Murata.

We are considering this point, we will give you more details later on how to proceed with the placement of the components
