Hi,
"Guidance" (rules-of-thumb) for relative mechanical strength of connectors fastened to PCB *solely* by their electrical contacts (no metal shells, swaged protrusions, etc.) in terms of stresses from the user trying to mate/unmate the connector in SMT vs thru-hole forms?
Are connectors in which insertion is normal to the PCB worse (in either technology) than those where the forces are *along* the plane of the PCB?
Any rule of thumb re: (total) foil areas vs. forces (without risking lifting foils or compromising mechanical strength?
Thx,
