Can JLCPCB do vias inside pads? There is solder mask on the opposite side of the pad. Will JLCPBB plug the vias or will the solder mask on the opposite side plug the via sufficiently? See image below. A .6mm .3mm via inside a 603 pad. ![via inside pad.png](//image.easyeda.com/pullimage/e8Pdksno5cyyTtoU8WeU5t1gXQWNs0i1AhfmDLZ4.png) Thanks in advance.
